INTRODUCTION Searchlight Sonar Basics Searchlight scanning sonars have many applications in commercial fishing, passenger ship navigation, diving and salvage and underwater security. The WESMAR 860-series of stabilized precision searchlight sonars are designed for high-performance, reliability and ease of use.

The WESMAR scanning sonar is a unique and valuable instrument because of its ability to “see” underwater in front, beneath and around the vessel.

Traditional depth sounders have fixed transducers that cannot be moved. They face straight down to the bottom, transmitting sound waves in a wide, cone-shaped pattern. Like an electronic “lead line”, the sound waves can only determine depth directly below the boat.

For sounders, a wide-angled sound beam is used rather than a narrow angle because the instrument can then cover a larger area. However, the wide sound beam produces insignificant and confusing echoes for the electronics (and eventually, the user) to interpret.

To locate underwater objects (fish, wrecks, rocks etc) with a depth sounder, you must cruise back and forth through the water until you pass over an object. In challenging locations, such as the Antarctic Peninsula or the Inside Passage to Alaska, this is not an option for a passenger vessel.

Similarly, for commercial fishing vessels, operators want to locate fish or fish-bearing bottom structures quickly to minimize time at sea, thereby maximizing safety and improving profitability.

WESMAR’s approach is to utilize scanning searchlight sonar technology.

Unlike a traditional echo sounder, scanning sonar does much more than indicate depth directly below the ship. It provides information on distance, depth and bearing of objects all around your vessel.

The transducer acts much like an underwater searchlight, turning up to a full 360 circle. The transducer can be tilted up and

down also, from +4 degrees above horizontal, to 90 degrees to profile directly below.

It is the narrow, moveable beam that enables the WESMAR scanning sonar to be used successfully in shallow water.

NOTE: THE USE OF SONAR FOR NAVIGATION SHOULD ONLY BE RELIED UPON BY AN EXPERIENCED OPERATOR IN CONJUNCTION WITH OTHER NAVIGATIONAL AIDS.

WESMAR 860-Series Sonar Models The 860-series is available in several different models, matched to the required application of the end user.

The HD860 Precision Searchlight Sonar is focused on the fish-finding requirements of commercial fishing operators, while the EV860 Navigation and Security Sonar is focused on the collision and grounding avoidance requirements of the passenger shipping and large yacht markets.

The WESMAR 860-series Sonars share a common system architecture, robust hydraulic hoist assembly and the following feature set:

· Active electronic gyro-controlled stabilization that is capable of correcting for 34 degrees of movement per second.

· 110 kHz frequency, in 8” and 10” soundomes, which has proven effective for navigation, fish-finding and underwater intruder detection.

Application: Commercial Fishing Application: Navigation and Vessel Security



· A highly targeted sonar beam with up to 280 elements in a large array transducer. The 860-series includes up to 30% more detection elements than conventional sonar, with greater transmit power and receiving sensitivity.

· The connectivity between the 860’s soundome electronics and the wheelhouse control unit is digital, and therefore resistant to interference from vessel electrical noise. Thus, sonar gains can be operated at a high power and sensitivity for optimum target detection.

· The system includes a unique “power booster” system that supplies high voltage to the transmitter. This ensures a strong transmit pulse for maximum transfer of acoustic energy.

· A heavy-duty hydraulic hoist system designed for the harshest weather conditions extends the 860’s urethane soundome up to 1.5m below the hull, away from air bubbles created by the vessel and weather.

· Sonar operation is simplified through an optional remote hand controller/joystick operation.

Please consult the Appendices for detailed technical specifications for 8” and 10” 860-series Sonars.

CASE STUDY: Passenger Ship Navigation The WESMAR EV850 Expedition Vessel Navigation and Security Sonar is aboard Lindblad Expeditions’ M/V National Geographic Explorer, commanded by Captain Leif Skog.

Lindblad Expeditions’ newest vessel, the National Geographic Explorer is an ice-classed expedition vessel described as the best-equipped expedition ship in the world.

Captain Skog reports:

“The new WESMAR 850 sonar works very well and is a very important tool for us. It’s a marvelous tool. We use it to find and avoid uncharted rocks and icebergs when we are cruising in remote areas. All cruise ships should have this sonar for navigation.”

Lindblad Expeditions M/V National Geographic Explorer



CASE STUDY: Commercial Fishing The WESMAR HD850 Precision Searchlight Sonar is aboard the C/P Arctic Storm, a 334’ Bering Sea Factory trawler, commanded by Captain Brian Styke.

Captain Styke reports:

“When the weather is rough the electronically stabilized HD850 soundome holds a sonar picture when others won’t.”

“With the HD850 we can find the bigger, more profitable fish hiding near the bottom, often very dense but hard to see with sonars of the past. The HD850 is one of our main fishing tools. On our most recent trip we were out 11 days and brought in 1,450 tons. That was a good trip.”

INSTALLATION PLANNING Sonar Location and Installation For vessels of 150 tons or more, the seachest should be installed within the forward 1/5th of the ship’s overall length, back from the bow.

On vessels of 50 to 150 tons, the seachest should be installed within the forward 1/3rd of the ship’s overall length back from the bow.

With smaller vessels up to 50 tons, the seachest should be installed 1/3rd to ½ of the ship’s overall length back from the bow.

Mounting the seachest too far forward will expose the soundome to turbulence and air bubbles. Installing the seachest too far aft will place the soundome close to the engines and propeller(s). They are sources of noise and can limit sonar performance.

Locate the seachest away from water intakes, discharge lines, or zinc plates that have been welded to the hull. Air bubbles and water turbulence caused by these objects during vessel movement can reduce sonar performance.

Avoid installing the seachest in the vicinity of existing transducers. Sounders and other sonar equipment, when operated at the same time, may interfere and cause a pattern to appear on the 860 Sonar display each time they transmit.

WESMAR recommends that the seachest be installed as close to the ship’s keel/centerline as possible.

A seachest installed too far from the keel will have reduced performance because it will be subject to increased turbulence and air bubbles.

Seachest Specifications Please consult the Appendices for technical specifications on length, diameter, wall thickness and mounting flange dimensions for 8” and 10” Steel and Fiberglass seachests.

All of the 860-Series Sonars have been designed to fit in a seachest with a length of 1m. If the top of the seachest rises above the waterline of the vessel, then the soundome can be



removed while the vessel is still in the water. To provide an installation with a removable soundome in a seachest that is below the waterline, install a gate-valve of appropriate size at the location of the seachest flange.

If you believe that you have non-standard requirements, consult WESMAR concerning the seachest when placing your order.

Seachest Flange For metal seachests, the seachest flange must be made of the same material as the seachest and welded to the seachest pipe. Consult the appendices for flange dimensions. A flange is included with WESMAR’s optional fiberglass seachest.

Installation Position The seachest must be perpendicular to the waterline.

Attach the seachest to the hull with standard shipyard practices. If the seachest could vibrate when the ship is under way, support it with gussets or stringers.

The bottom of the seachest must be 1cm (0.5”) above the bottom of the keel. This ensures that there is no pressure applied to the seachest when the vessel is dry-docked.

SPECIAL NOTE: The WESMAR Model M-18 hoist does not require the seachest to support the soundome during vessel movement. Therefore, the seachest can be installed flush with the outside of the hull bottom. This is the typical installation for large vessels such as cruise ships.



MOUNTING OF SYSTEM COMPONENTS Unpacking and Inspection The 860 Sonar should be carefully unpacked and examined for any damage that may have resulted from shipping. Report any damage to the carrier immediately.

PLEASE READ ANY TAGS THAT MAY BE ATTACHED TO THE EQUIPMENT BEFORE ATTEMPTING TO INSTALL THE SONAR.

DO NOT REMOVE ANY TAGS UNTIL AFTER THE SONAR HAS BEEN COMMISSIONED.

Introduction A significant percentage of the installation effort required to successfully commission a WESMAR 860-series Sonar can be accomplished, with proper planning, before a ship goes into drydock. If cabling and control boxes are connected prior to the welding of the seachest and coffer dams etc, then the sonar can be commissioned and put to effective use immediately after a vessel returns to service.

NOTE: Installation in Double-Bottom Vessels In ships with a double-bottom, the Sonar seachest and hydraulic hoist may need to be installed in a water-tight compartment or “Sonar Room”. It is your responsibility to consult with a qualified Naval Architect and your Classification Agency (for example, Lloyd’s Register) to implement the sonar installation safely.

The following photograph shows an example of a well-planned installation where the Sonar was placed in a dry tank/coffer dam within a cruise ship’s double-bottom.

Penetrations for Cables and Hoses Consult with your Naval Architect for an approved method for passing electrical cables and hydraulic hoses which are required for the Sonar’s operation to the hoist location. We have successfully implemented Roxtec-type cable glands in previous installations.

Transmit/Receive and Power Boost Boxes Please see Appendix 14 for a suggested mounting pattern for the Transmit/Receive and Power Boost boxes. It is important to allow enough space between the boxes so that they can both open without interference. However, they should also be sufficiently close (within 3m) so that the 2 boxes can be integrated without having to extend the WESMAR factory-supplied cabling.

Sealed tank installation

Control boxes mounted outside of the tank



The hydraulic hoist assembly includes pre-drilled holes for mounting control boxes and the hydraulic power pack directly to the hoist. This could be an excellent and compact option for installations that are guaranteed to be dry, warm and accessible.

However, if the hoist will be in a sealed tank, it is strongly recommended to mount the boxes in an accessible location outside of the tank. The following photos illustrate examples of well-planned and implemented installations.

Hydraulic Power Pack The hydraulic power pack has multiple mounting options. It may be directly attached to the hydraulic hoist assembly, or may be installed on a separate rack.

The 860 Sonar is usually shipped with tags that help to connect the correct hydraulic hose quick-connect fitting to the correct fitting on the hydraulic RAM. However it is prudent to consult Appendix: Hydraulic Components to ensure that the correct connections are made.

The WESMAR factory-supplied hydraulic hoses are Gates Corporation 6M3K (JIC-6 fittings, 3/8” or 9.5mm, 3000 PSI). The default hose length is intended to support installation of the power pack directly on the hoist assembly.

If you are mounting the hydraulic power pack away from the hoist, consult with WESMAR for customized hose lengths.

HYDRAULIC HOIST ASSEMBLY

Introduction The hydraulic hoist is the physical assembly that lowers the sonar soundome into the water below the vessel’s keel, and then retracts it into the seachest when not in use. The hoist will be assembled after an appropriate seachest and bolting flange (supplied by WESMAR or your shipyard) has been installed. Note: The seachest installation (materials and welds) may need to be approved by a surveyor from your Classification Agency.

For testing of the hoist assembly, it is very helpful for power to have been run to the location where control boxes and the hydraulic power pack are mounted.

Verify Hoist and Power Pack components WESMAR ships the sonar system in one or more robust shipping containers, such that shown in Figure: Factory Packaging. In some cases, the hydraulic hoist assembly will be pre-assembled by the factory.

Recommended tools (customer-supplied) The assembly of the hoist assembly will be aided by having the following equipment available at the site:

· 1.5” socket and open box wrenches for flange bolts. The availability of a “rattle gun” impact wrench is extremely helpful.

· 0.75” socket for hoist bolts

· 0.375” (3/8 “) Allen-key T-wrench for tightening recessed hex bolts

· “Stubby” Philips-drive screwdriver for adjusting limit switches

· 1t+ capacity chain hoist with lifting strap(s), attached to a sturdy overhead ring.

· Shop cloths/sorbents

· Portable shop light or flashlight

WESMAR ships all required bolts, lock-washers, nuts, flax packing, gaskets, O-Rings, PVC tube bearing, Permatex anti-seize and O-Ring lubricant with the system.

Figure 1: Factory Packaging



Verify the Seachest Installation Prior to assembling the hoist, it is prudent to verify that the seachest installation is satisfactory. Ensure that the mounting flange has been welded at 90 degrees to the steel pipe. If possible, run a plumb line from the overhead to ensure that the seachest is straight. The interior of the seachest should be fair and free from “burrs” and sharp edges that might interfere with the soundome.

If the mounting flange is not perpendicular to the pipe, the hoist could contact the interior of the pipe while raising and lowering the soundome. It is much easier to correct this type of issue early!

The interior of the seachest should be coated with an appropriate antifouling paint prior to the hoist installation.

Finally, it will be very helpful if a lifting ring is available above the seachest to allow for the use of a chainfall to raise and lower the assembled hoist onto the seachest.

Install Hydraulic Motor and Hoses The hydraulic motor can be mounted on bulkhead standoffs (See Installation Planning), or it can be fastened to the 2 pre-drilled mounting holes on the hoist assembly leg that is opposite to the limit switches.

The motor is relatively heavy so ensure that it is well supported with a lifting strap or by a helper while being fastened.

Remove the temporary metal oil-fill (supplied to prevent leakage during shipment) cap on the motor and replace with the black plastic screw cap. The plastic thumbscrew provides 1500 PSI pressure-relief and is mandatory.

If not pre-connected, attach the hydraulic hoses to the manifold on the motor and tighten the threaded connections. Do not use Teflon tape on these connections. Consult Appendix: Hydraulic Components to ensure the right hoses on the motor (Up/Down) are connected to the correct connections on the RAM.

Install the unit so that the motor is up, and the reservoir is down.

Ensure that the soundome moves smoothly and doesn't bind in the

seachest

Installation onboard a 90m expedition vessel



The hydraulic system is tested and calibrated at the factory before shipping. The hydraulic system should not require any more oil. If the hydraulic hoses have been lengthened, the reservoir will require more oil.

(OPTIONAL) Field-test of Hydraulic RAM Note: If electricity has not yet been run to the hoist location, the hydraulic motor can be temporarily “hot wired” for test purposes. Connect the motor’s power supply lugs (white, black, green) to an appropriate AC source.

The hydraulic RAM assembly can be field tested prior to its attachment to the soundome tube.

Attach the hydraulic hose quick-connect fittings to the ports on the RAM.

Turn on the hydraulic motor (see the section above on “hot wiring” the hydraulic motor. Take a push-pin and manually activate the hoist solenoid (for both sides). When the solenoids are activated the hydraulic Ram will move in its intended direction.

Turn the motor off. Disconnect the quick-connects and set the hydraulic Ram aside.

Install flange Base, Soundome tube and Packing The following instructions assume that there is sufficient overhead vertical clearance to lift the complete hoist and soundome assembly and place it on the seachest flange. If vertical clearance is limited, then the soundome could be attached outside of the vessel.

Install the zinc collar at the base of the soundome tube, above the mounting flange for the soundome.

In most cases, a PVC tube bearing and flax packing will be already inserted into the flange base weldment at the factory. If this is not done, push the PVC bearing into the flange base until it bottoms out.

Add in 5 layers of flax packing, staggering the ends of the layers at 90 degrees to each other. Attach the packing cap with its 2 tightening bolts but keep the bolts loose at this time.

Lay the hoist flange weldment on its side and push the soundome tube about half-way through the base. The end of the

Zinc Collar

soundome tube with the zinc collar and mounting flange should be on the side that will drop down into the seachest.

The fit between the soundome tube and the packing gland will be relatively snug. Avoid binding the tube in the flange base.

Run a sturdy line through the holes at the top of the soundome tube, so it can be lifted straight up with the chain host and set down on the seachest flange. The soundome tube, with the flax packing, may be tight enough at this point to release the chain hoist. However, be very careful that the tube is secured so that it cannot fall through the vessel!

Install Hydraulic Cylinder Assembly Insert the hydraulic Ram assembly into the soundome tube and rotate it so that its 3 tapped bolt holes line up exactly with the drilled holes in the soundome tube.

The fit will be snug. You may find that a very light tapping with a rubber mallet will help to align the fastener holes.

Attach the Ram assembly to the soundome tube with the supplied recessed Allen/Hex head bolts, after applying some anti-seize compound to the bolts.

It is very important that all three hex-head bolts smoothly engage with the tapped hydraulic cylinder assembly. Take your time with this operation and ensure that all 3 holes line up correctly and that fastener threads are not stripped!

Carefully consider the orientation of the hydraulic cylinder assembly versus the limit switches on the hoist. During operation, ensure that hydraulic hoses and the soundome cable will not interfere with the limit switches!

Install Hoist legs, Tube clamp and Cross members The hoist rack assembly includes 4 angle-iron legs and 2 angle-iron cross supports. Each of the 4 angle legs is labeled. Match the same name label of the angle leg to the corresponding location on the flange base brackets. Pins have been driven through the flange leg bases to ensure that you cannot mount the legs on the wrong sides of the brackets.

For the 10” Sonars, it is important to insert a large 1.5” seachest flange mounting bolt, threaded end down, at the base of each of the 4 flange legs. Later, the other mounting bolts will be inserted with the threaded ends facing up.

3/4" Bolts on Hoist Assembly

For proper hoist operation, cams must engage limit switches fully!

Limit switches may be field-adjusted up or down.



Assemble the hoist legs with the correct 0.75” bolts, nuts and lock-washers. Do not tighten too much at this point. Allow some ability for the hoist to flex.

Assemble the 2 halves of the tube clamp guide assembly with the supplied bolts, and slide over the soundome tube. Align the clamp guide so that cams will engage the hoist leg with the limit switches. The tube clamp guide stabilizes the soundome tube’s travel and triggers the limit switches to stop hoist travel. It is very important to secure the tube clamp close to the 3 hex head bolts so that the factory limit switch settings will engage properly.

Install and hand tighten the fasteners for the top cross members. Attach the clevis of the hydraulic ram to the center of the angle cross supports. Carefully remove the circlip that secures the pin to the clevis and then re-attach once secured to the cross supports.

Slide the soundome tube clamp assembly up the soundome tube so that it is just below the three alignment bolts holding the ram end cap. Tighten the bolts on the tube guide evenly, but do not over tighten.

Attaching the Soundome Note: The images for this section show an installation where a soundome was attached from outside the vessel. The soundome is shipped with a carrying chain attached to eyebolts. Do not carry or support the soundome’s weight by the soundome cable.

Use the chain hoist to lift the entire hoist assembly after looping a lifting strap to the top cross members. Unscrew the strain relief for the soundome cable that is located on top of the hydraulic cylinder assembly. Drop a messenger line through the soundome tube. Place the soundome O-Ring gasket over the Soundome cable. Lubricate the O-Ring with the supplied LanoLube and press into the appropriate groove on the soundome. Use the messenger line to tie down the various electrical connection lugs on the soundome cable so that they can be fished

The soundome can optionally be attached from outside of the

vessel.

Never lift the soundome by its cable!



without binding. Use some plastic and electrical tape to package up the wires into a smooth package that can be easily fished up through the top of the hoist. Fish the soundome cable up through the top of the hydraulic cylinder.

Mark the location of FORWARD (facing the bow) on the soundome tube and align this mark with the FWD mark on the soundome. Any misalignment can be corrected by the Sonar’s operating software, but it is good practice to install facing forward.

Attach the soundome to the base of the soundome tube with the supplied bolts and washers, not forgetting to apply anti-seize compound. . Pull the soundome cable taught (not tight) and then ratchet down the strain relief.

Mount the Assembled Hoist to Seachest Place the large neoprene gasket over the steel seachest flange (See Figure). Ensure that the holes in the gasket are centered on the holes on the seachest. Place the hoist flange on top of the gasket. Loosely place the mounting bolts through the flange holes. Threads should protrude UP through the flange. Loosely install the lock washers and nuts with anti-seize but do not fully tighten yet.

Completing the Hoist Installation With the chain hoist still attached to the hoist, please ensure that there is no binding of the hoist legs with the tube guide. Ratchet down all the bolts except for the seachest flange. Connect the hydraulic hoses. Assuming that the hydraulic pump is mounted on the hoist leg labeled Pump, attach the hoses to the nearest threaded connection on the pump manifold. Facing the pump, the connection on the left will be “Down” and the connection on the right will be “Up”. Plug in the hydraulic pump and test the up and down motion of the hoist by manually activating the solenoid. Once the unit moves smoothly without any binding in the seachest, then tighten the seachest bolts. A “rattle gun” impact wrench is very useful for securely tightening these bolts.

WIRING THE 860 SONAR Safety Notes Ensure that the Sonar area (especially if located in a sealed tank in a ship’s double-bottom) is properly ventilated prior to entry for servicing. Observe all ship’s maintenance procedures and regulations. For example, obtain a tank entry permit prior to opening and entering confined areas.

Under no circumstances should repair or adjustment of energized equipment be attempted alone. The immediate presence, on-scene, of someone who is capable of rendering first-aid is required.

Consult with your naval architect and Class Society for approved methods for routing electric cables and hydraulic hoses on your vessel. For Sonars that are installed in watertight tanks, cables may need to be routed through cable transits such as those manufactured by Roxtec Int’l.

See the Appendices of this Manual for Schematics and wiring diagrams for the various cables.



Power Booster & Hoist AC Voltage The power booster and the hoist board are factory wired at WESMAR for 110 VAC or 220 VAC single phase. It is possible to change the voltage in the field. However, you must have a set of solenoid coils on hand in order to complete the change.

Devote one 20 amp circuit breaker for the sonar for 220 VAC installations (30 amp circuit for 110 VAC). This circuit will supply power to the hoist motor and all electronics. Connect ship’s AC to terminal block TB3, “AC in”, located at bottom left on the hoist board. Connect terminals #30 & #31 “AC In”. If used, connect terminal #32 as ground.

The power booster is wired at WESMAR with a US stile 110 VAC plug. This plug is on all units. The standard installation practice is to cut the plug off, strip the wires and crimp on lugs

. Pass the cable through a small strain relief in the T/R box. Connect the wires to TB5 “AC out”. Connect the black & white wires to terminal #30 & #31. Connect the green wire to terminal #32. Refer to Appendix: AC Wiring.

Interconnect Cable The standard 850 Sonar Interconnect (IC) cable is 65 feet (19.8 meters) long. On some passenger ships, the IC cable is custom-fabricated to over 100m in length. The connector end will mate with the computer console in the wheelhouse. On some installations, the Interconnect cable may have been deployed in multiple sections, connected by one or more J-boxes.

The other end is terminated with lugs. Rout the cable through a large strain relief and connect the lugs to the numbered terminals as in the Appendix: Interconnect Cable Wiring.

For hoist configurations that lack a middle limit switch, do not connect Lug #8 (white wire). If connected, the yellow LED on the panel control will light, even though the middle limit setting is not available. Wrap Lug #8 in electrical tape.

Soundome Cable The soundome cable must not pass through the hoist on the side of the limit switches. Have enough slack in the cable so it can move down and up with the soundome tube. Make sure there is no possible way the cable can snag with boat movement.

Wiring the Power Booster Box

Wiring the Transmit/Receive Box



Route the cable through a large strain relief and connect the lugs to the numbered terminals as in Appendix: Soundome Cable Wiring.

Power Booster The power booster supplies operating voltage to the TR board and high voltage for the transmitter. The power booster must be installed next to the TR box. Use the pre-wired cable.

Route the cable through a small strain relief on the TR box and connect the lugs to the numbered terminals as in Appendix: Power Booster Wiring. Check the wiring as there are two #1’s and two #3’s.

Panel Control The panel control has three cables. One for hoist control, one for system operation and one for DC power in.

Hoist control is the cable with ten lugs. Pass the cable through a small strain relief in the computer console. Connect the lugs to the terminal block in the upper left. Connect all ten wires starting with lug #1 at the top.

The joy stick and quick switches run through the cable with the connector at the end. Mate this connector to one of the connectors on the computer console. There are two connectors - either of the two will work.

The third cable is for DC voltage. This voltage is used by the computer console. It also goes down the interconnect cable to energize a relay in the power booster. This relay will turn on the AC voltage to power up all the electronics at the hoist end.

Connect the cable to a 12 volt or 24 VDC source that is able to supply 1.5 amps.

Hand Control The hand control has the same functions as the control console with the exception of turning the system on and operating the -hoist.

The hand control can be connected direct to the computer console. In a standard installation an extension cable with bulkhead connector will be installed. The extension cable standard length is 15 feet, 4.6 meters; however, the cable can be extended to any length.

Computer control console in the wheelhouse



Hydraulic Hoist The hoist board controls the raising and lowering of the soundome. There are four cables coming from the hoist assembly that are connected to the hoist board: the AC power for the hydraulic pack, the solenoid valve and two cables from the limit switches.

Run the AC hydraulic motor power cable through a small strain relief, run the solenoid valve cable through a small strain relief, run both limit switch cables through a small strain relief. Connect the lugs to the numbered terminals as in Appendix: Hoist Wiring.

Wheelhouse Monitors(s) If using two monitors connect the #1 monitor to the video connector to the right. For commercial fishing applications, a second monitor can be used to view Trawlscan (Select Screen #3 from the 860 Main Menu) available from video connector #2 left.

For operators who would like to have the ability to control the Sonar from multiple locations, including bridge wings, please contact WESMAR for junction boxes and additional cabling.



SONAR COMMISSIONING Order of Operations After installation the sonar system is ready for its operational check. Part A is performed before the boat goes into the water. Part B & C are performed when the boat is in the water dockside.

Electronic check, Boat is out of the water This check is to confirm the electrical parts of the sonar and soundome are operating correctly before the boat goes back into the water. The hoist is to be disabled during this test. Failure to disable the hoist may result in soundome damage as it is driven into the ground!

Disable the hoist so it cannot move by removing the fuse from the hoist board.

a. Turn the hoist AC breaker OFF.

b. Remove the fuse on the hoist board, F1, lower left.

c. Turn the hoist AC breaker ON.

Check all cable wires in the Transmitter/Receiver Box for loose connection on terminal strips.

Check all cable wires in the Power Booster for loose connection on terminal strips.

Check all connectors into the computer control unit in the wheelhouse.

Turn the wheelhouse Sonar monitor(s) ON.

Turn the sonar ON by rotating the rotary switch one click to the left, (Counter-clockwise, CCW). No lights on the panel control will light at this time.

The Sonar will enter its Power-On/Self Test mode:

a. Software (console) Release (some number). This is the software that is in the computer control unit.

b. Hardware (console) 1234567. This is the serial number of the microprocessor in the control console.



c. Software (remote) 8-6B. This is the software in the transmitter/receiver box down by the hoist.

d. Soundome (remote) 110 kHz 10 inch. Make sure this is the correct frequency and size of the soundome installed on the hoist.

e. SETTINGS: Passing the test the word “settings” will display green in color . This test checks computer memory and all the sonar settings from the last time the sonar was in operation.

f. PROGRAM: When the sonar program is running without complications the word program will display green in color.

g. LINK: When the computer control unit in the wheelhouse communicates with the transmitter/receiver unit near the hoist assembly and back up to the computer control unit the word “link” will turn green. No only is this a check of the electronics but it is a check of the interconnect cable between the two.

h. SCAN: Every time the sonar is turned on the soundome must locate zero degrees. When zero degrees is located the word “scan” will turn green in color.

For the Sonar’s initial operation, adjust the following settings:

Check for receiver noise. The transducer is now scanning 360 degrees inside the seachest. Do not expect to see targets.

Turn both sonar near and far gains up until noise is displayed on the screen. Both gains may need to be up to 100% to see noise. If noise is not visible lower sonar threshold from 3 to one and delete 0 colors. Noise should be visible.

Check for transmit. Set sonar speed to zero. Go below to the hoist. The area must be quiet. Place your ear to the hoist rack. There should be a ticking sound. If you cannot hear a ticking sound, adjust for sonar for 100% pulse and 100% power. Ticking sound should now be heard.

This completes the “Out of water check”. Turn the sonar and monitor OFF. Turn the hoist AC breaker OFF. Replace the fuse back into the hoist board.

Take note of the hoist fuse: 110 VAC hoist = 30A MDL Slo-Blo; 220 VAC hoist = 20A MDL Slo-Blo. Always have a few spare fuses taped to the inside of the T/R box.

Hoist check (IN THE WATER) IMPORTANT: Ensure that there is at least 2m of water beneath the seachest, and a rising tide!

Check all cables from the hoist:

1. Soundome cable must be free from snags as it moves up and down. The soundome cable must avoid rubbing against the limit switches as it moves.

2. Hoist motor and limit switch cables can be tied together. Wires must be protected from chafing during vessel movement.

3. Check the hydraulic hoses for possible snags and chafing during movement.

Check the packing gland for water. Tighten the packing gland so water is just weeping. Do not over tighten. A packing gland that is too tight may create excess friction on the soundome tube that results in the stalling of the hoist motor and the blowing o f uses.

Check the hoist motor’s supply of ATF oil. Remove the vent screw in the side of the reservoir. Fluid level should be just below the opening. Use standard ATF fluid to top off.

Turn the AC breaker on to the hoist. The hoist tub may jump up if the top limit switch is not triggered. Once triggered, the motor



will stop running. If the upper limit switch is not fully engaged, the limit switch must be adjusted lower.

Before turning the sonar on have a person at the hoist. If hoist movement is not correct they can report back to the wheelhouse by radio or turn the ac hoist breaker switch off.

Consult the Operations Chapter, to turn on the Sonar and go through its Power-on and Self-test (POST) mode, and instructions on lowering and raising the hoist, and troubleshooting.

Sonar Check (IN THE WATER, AT DOCKSIDE) Turn the sonar on and lower the hoist. NOTE: Refer to the following Operations chapter for guidance on how to use the system menus and controls.

Set the sonar to its initial recommended configuration. For the in-water check, adjust the following settings from the initial settings:

a. SONAR.

Pulse = 25%

TVG (160kHz) = 300 to 400

TVG (110kHz) = 500 to 700

TVG (60kHz) = 800 to 1000

Power = 25 to 50%

b. PROFILE. Pulse = 12%

TVG (160kHz = 200 to 400

TVG (110kHz) = 400 to 600

TVG (60kHz) = 700 to 900

Power = 25 to 50%

Select Screen #1: Full-screen Sonar. As the sonar scans a full 360 degrees adjust the sonars near and far gains for a good display of the dock. The dock should fill 2/3 of the screen. If not adjust the range so it does. The angle of the dock on the screen should be the same in reference to the boat seen visually. If the angle is not correct go to LOCAL, then



OFFSET. Change the degrees until the picture on the screen is the same seen visually.

Select Screen #2: Split screen, sonar with profile. The Profiler will sweep from starboard to port. Adjust the profile near and far gains for a good presentation of the bottom. If the gains become too low or hard to adjust reduce power and pulse. The bottom should repeat or overlay on each sweep. It should not change in angle. If the bottom is changing every other sweep go to LOCAL, then TILT CAL. Change the number in TILT CAL so each profile sweep repeats accurately.

Select screen #3 if there is a second monitor connected to the computer unit. Go to LOCAL then TRAWLSCAN. Select Numbers 1 through 4, one at a time. Watch the second monitor and confirm targets are displayed. Some tilt may be needed along with short range. TRAWLSCAN is designed for deeper water than is typically found at dockside.

Select Screen #4: Full-time Down Sounder. Select a short range, low gains, low power and pulse. Adjust gains for a good bottom display. Make a depth measurement. Add to it the draft of the vessel plus the travel of the hoist. The sum should equal the depth of the water.



OPERATION

The best way to become proficient with your Sonar is to use it often. The more you work with it, the more valuable it will be as a navigation or fish-finding aid. Don’t be afraid to experiment with the controls. .

Basic Sonar Operating Conditions Like all sophisticated computer equipment, the 860-Series Sonar has temperature limits of 0 degrees to 43 degrees Celsius (32 to 110 degrees F).

THE SONAR SHOULD BE OPERATED ONLY WITHIN THESE TEMPERATURE LIMITS.

The WESMAR 860-series Sonars are being used today for the following applications, with more to come in the future:

1. Location of large compact schools of midwater fish, such as herring, sardine, mackerel and tune, in deep water.

2. Location of large compact schools, such as Pollock, in shallow water with a smooth, soft seabed.

3. Location of scattered schools of mid-water fish such as herring, mackerel and large individual fish like salmon, albacore tuna and blue marlin in deep water.

4. Detection of rocks, reefs or other bottom structure for bottom trawlers, red snapper fishermen, research vessels and salvage operators.

5. Detection of collision and grounding hazards, including shelves, reefs, icebergs by large yachts, expedition vessels and cruise ships.

User Interface The 860-series Sonar is configured and operated via a software user interface, which can be navigated using either a bulkhead-mounted Panel Control or a remote Hand Controller, both of which are supplied with the Sonar.

The control devices plug into the Sonar’s wheelhouse PC control box and require panel cut-outs close to the Sonar screen.



Power-On and Self-Test (POST) Turn the Sonar ON by rotating the rotary switch on the Panel Control one click to the left (CCW). No lights on the panel control will light. The Sonar will enter its POST mode with the following display:

a. Software (console) Release. This is the software revision in the computer control unit.

b. Hardware (console): This is the serial number of the microprocessor in the computer control unit.

c. Soundome (remote): 110 kHz, 10 inch. Ensure that this is the correct frequency and size of the soundome that has been installed on the hoist.

d. SETTINGS: The word SETTINGS will display in green. This test checks computer memory and all the sonar settings from the last time the Sonar was in operation.

e. PROGRAM: When the Sonar program is running without complications the word “PROGRAM” will display in green.

f. LINK: When the computer control unit in the wheelhouse communicates with the transmitter/receiver u nit (near the hoist assembly) via the Interconnect Cable, then the word “LINK” will turn green.

g. SCAN: Every time the sonar is turned on the soundome must locate zero degrees. When zero degrees is located, the word “SCAN” will turn green.



IF THE SONAR FAILS THE SELF-TEST, CONTACT YOUR DEALER OR WESMAR

(+1-425-481-2296) FOR SUPPORT

Software Menus and Control The Sonar’s user interface is navigated by either the Panel Control joystick/buttons or the Remote Hand Controller.

Remote hand controller with buttons and trigger



The Main Menu (titled “WESMAR 860”) of the 860-series displays the current Sonar targets and a vertical Menu bar to the right that includes the primary “controls” for the system: Range, Tilt, Center (Bearing), Reverse, Thickness, Sector, Speed, Zoom, Screen, Set Up, and Gains (Near/Far).

To adjust the sonar for the application push the enter button on the control panel or pull the trigger on the hand controller. A menu item will light in green. Use the up/down joystick to scroll from one item to another. Use the right/left joystick to make selection.

Pull the trigger or push the button a second time will remove the green highlight from menu. When the green highlight is removed from menu the joystick will then control the cursor. Move the cursor over a target will give horizontal range to and depth of the target.

The remote handheld controller and the bulkhead panel control unit also include 3 buttons which provide for quick access to common function: Button 1: Range, Button 2: Center/Bearing and Button 3: Sector Angle (in degrees)

The Sonar is configured by clicking on the main menu item “SET UP”. Configuration settings are grouped by: Sonar, Profile, Colors and Local.

Basic Operation (the main WESMAR 860 Screen)

SCREEN There are 4 screen selections that can be accessed by clicking on the “SCREEN” menu item:

Screen 1: Full-screen: 360 degree Sonar view Screen 2: Split-screen: Sonar with simultaneous bottom profiling [very popular for Navigation applications] Screen 3: Trawl Scan: Commercial fishing view Screen 4: Full-screen down sounder. This stabilized sounder mode can also be used when the soundome is retracted.

Main Menu Bar



Screen #1: Single screen – Sonar scanning forward with adjustable tilt.

Screen #2: Split screen – Sonar scanning forward with adjustable tilt and simultaneous bottom-profiling.

The 860-Sonar Series enables multiple views

around and below vessel:

860 Sonar operating as both a horizontal scanning sonar and bottom

profiler

In Video-sounder mode with transducer stabilized. Can be

operated when soundome is fully retracted

Screen #1: Full-screen Sonar

Screen #2: Split screen sonar and profiler



Screen #4: Full-screen down-sounder is available even when the soundome is fully retracted.

RANGE Sets the distance that is covered on the display screen. There are 2 selections, one for Sonar and another for Profile. Range can be set in units of Feet, Fathoms or Meters.

TILT This configures the scanning angle of the transducer below Horizontal (0 degrees). Minus 90 degrees tilt is straight down. Positive tilt is above the horizontal. For Navigation applications, it will be typical to set TILT to 0 degrees, and perhaps lower several degrees to eliminate interference from wave action.

CENTER (or Bearing) This marks the center of the scanning sector. Center can be moved in nine-degree steps around the screen. It is normally set to zero degrees when scanning forward.

SECTOR This sets the number of degrees scanned. There are 2sector selections, one for Sonar and the other for Profile.

Screen #4: Full-Screen Stabilized Down-Sounder



ZOOM Zoom is used as a magnifier. Move the cursor over the target and pull the remote handheld trigger or push the button on the panel control. The enlarged target will display in the lower right of the screen. Pull the trigger or push the button again to disable the function.

SPEED Sets the scanning speed of the transducer. Use the slowest speed 1 for the highest resolution. Each number is equal to 1.8 degrees of rotation. There are two speed adjustments (for Sonar and Profile). Adjust the speed for best target presentation.

SET UP Transfer to Sonar, Profile, Color and Local menus where detailed adjustments can be made.

GAINS (NEAR and FAR) Near Gain controls the complete gain curve and has its greatest affect on targets displayed in the first half of the sonar range. Far Gain controls the height of the gain curve and has its greatest affect on targets displayed in the last half of the sonar range.

When both Near and Far Gains are adjusted correctly, targets at long range will not change in density as the vessel approaches. Also, target density will remain constant from one range to another. Gain settings can be adjusted for all conditions the operator will encounter, ensuring accurate target presentation.

Gain settings can be adjusted independently for both Sonar and Profile modes.

Sonar and Profiler Configuration (SONAR and PROFILE)

PULSE At the beginning of each Transmit/Receive cycle the transmitter turns on and off in a brief period of time called the Pulse Length, and is measured in milliseconds (1/1000th of a second). Pulse Length is equal to 1.5m/ms. The Pulse Width can be manually adjusted depending on the acoustic environment and target characteristics. For example, a shorter pulse will give better target definition and reduce volume reverberation when looking for dispersed or small targets in the water column.

Scanning Bearing and Sector is fully adjustable



A long pulse may be used when seeking out large targets at long ranges. Pulse length can be selected from BOOST (longest) to 3% (shortest). NOTE: A Zero pulse length will turn the transmitter OFF, which is useful for eliminating sources of interference.

ENHANCE This is a filter that enables a stronger display of weaker targets. Normally set to 3.

LIMITER This is useful to reduce external interference, such as acoustic interference from other sonar/sounder equipment onboard, and electrical interference from power supplies and cabling. Under normal conditions, Limiter is set to OFF.

Selecting Limiter #1 creates a requirement that a sonar target must be present in two adjacent transmits at the same range. Selecting Limiter #2 requires that three consecutive target samples are received and the lowest sample will be displayed. Both #1 and #2 can be selected to further reduce noise. CAUTION: Activating Limiter will remove smaller targets. Limiter can be adjusted independently for Sonar and Profile.

FILTER Will eliminate weak targets and light noise from the screen. Filter is normally set to OFF.

TVG (or Time-Variable Gain) The Normal TVG Setting for a 110kHz system is 400-600 mSec.

The TVG (Time-Variable Gain) setting adjusts the receiver gain based on Sonar range, to offset the propagation loss of sound as it passes through the water.

Propagation Loss of sound is the sum of Spreading and Attenuation Losses. Spreading Loss refers to the physical spreading of sound energy as it travels outward from the source and back from the target. Attenuation Losses are primarily due to absorption and the scattering of sound as it passes through the water.

Automatically adjusts receiver gain based on Sonar range. As sound travels through water, it loses strength due to propagation losses (attenuation). This makes distant objects seem weaker. As targets approach they appear stronger and stronger. To



offset propagation losses the sonar gradually increases sensitivity or gain relative to range.

With the correct TVG setting, targets at long range will have the same color as they approach. TVG numbers change with frequency and water temperature. Warmer waters support more plankton and plant life that absorb sound energy. TVG can be configured separately for Sonar and Profile.

A Zero TVG will not adjust gain based on sonar range. Zero TVG is used when checking boat noise levels.

POWER Sets the output power of the transmitter. Use 100% power for long range. Low power is useful in shallow water and conditions where there is a lot of plankton or algae suspended in the water column.

Color Configuration (COLOR Screens)

THRESH (or Threshold) Selections range from 1 to 6. Strong targets mark in red, yellow or orange. Weaker targets mark in green and blue. Thresholds 1-3 have 25 colors. Thresholds 3-6 have 8 colors. For strong targets and schooling fish, select 3 or 6. For ground fish and bottom typing, select 1 or 4. Delete colors as necessary to remove clutter. All colors can be deleted with the exception of the clipped color.

Sonar and Profile have their own threshold adjustment. NOTE: If the selected background is black and the selected clip color is black, then no targets will display on the screen!

DELETED This will remove colors from the screen from weak to strong. One way to remove clutter from the screen is to delete colors. Colors can be deleted independently for Sonar and Profile.

CLIP Sets the color for the hardest targets. Choosing a color other than Red can help distinguish the bottom from targets that are very near the bottom. Adjust the gains so the strongest target marks in the Clip color. Clip color can be selected independently for Sonar and Profile.



BACK Sets the background color of the screen: black, blue or white. For blue or white background to appear, delete at least one color.

PALETTE Will lower the brightness of target colors without eliminating them, starting from blue to yellow. Sonar and Profile have their own palette adjustment.

CURSOR Sets the color of the cursor and marks on the screen.

TEXT Sets the brightness of the white numbers and letters. Will not affect the sonar target colors.

Local Settings Configuration (LOCAL Screen)

UNITS Select meters, fathoms or feet as the unit for range.

ENGLISH Select the language for the display. English is the default.

TEXT Sets the brightness of the white numbers and letters. This will not affect the sonar target colors.

MARKS Turn the range rings and range lines ON or OFF. The range rings represent 25%, 50% and 75% of the configured range.

OFFSET Aligns the image on the screen with respect to the bow in plus or minus one degree steps. Configure the offset to adjust if the FWD mark on the soundome is not accurately directly aligned with the forward direction.

TILT CAL Tilt calibration is used to adjust the angle of tilt at both ends of the transducer. Calibration is made when running Screen #2 at dockside. Observe the bottom profile on the screen. Each sweep should repeat over the one before. If not, make a change in Tilt Cal + or – until each profile sweep repeats itself.



TUNING Adjusts the frequency of the transmitter. This should match the factory setting (110 kHz is the standard). To reduce noise or interference, adjust the frequency up or down for the best picture. The factory frequency setting is noted on the inside of the Transmit/Receive Box and may vary from the nominal 110 kHz by several degrees.

SCOPE Fish loop or “A” scan are other names for Scope. In screen #4 (Down Sounder), the “A” scan will display on the right of the display. “A” Scan can be turned On or Off.

SHAPE Can be set to either Circle or Square. For a Circle setting, the sonar will mark targets that lay within the diameter (Sonar Range) of the circle. For a Square, the Sonar will mark targets into the corners of the square. The corner of the square is 1.4 times the range of the circle’s diameter.

STABILIZER When stabilize is set to OFF the transducer will move with the ship. Selecting 1 or 2 will turn stabilization on. The transducer will then correct for the motion of the ship. For light seas, select #1. For heavy seas, select #2.

Scanning Sonar Techniques

In Deep Water If the vessel is being operated in deep enough waters so that the sonar receives no bottom echoes when being operated at a 5 degree tilt, set the sonar on medium or long range and adjust the GAIN controls high enough to receive bottom echoes from shallow water at long ranges and set SECTOR SIZE for a 90 degree sector.

Be certain to use enough FAR GAIN and NEAR GAIN to detect even a gently sloping mud seabed. When properly adjusted, the sonar will display fish schools, boat wakes and other major changes in the water.

Although it is possible under ideal circumstances to locate surface targets such as large logs and boats, the sonar is not a reliable tool for detection of these surface targets and should only be used for locating underwater targets.



In Shallow Water At dead-slow speed, the sonar can be used to provide a depth indication of waters immediately ahead and around your vessel.

Operation of the Sonar in shallow water requires a different technique and a little more practice. In shallow water as the sound is projected out horizontally at a 0 degree title angle from the vessel, the cross-sectional diameter of the beam gets wider and wider. As the sound beam goes out at a distance from the vessel of approximately 4-6 times the depth, the sound beam will begin to intersect the bottom and the sonar will receive bottom echoes.

If the bottom is smooth and flat most of the sound energy will be reflected away from the vessel and by using a relatively low sensitivity level the sonar will receive very few bottom echoes.

If the water suddenly becomes shallower, as at the edge of a channel, the edge of the channel will be a more perpendicular target to the sonar beam and will reflect more sound energy which will be displayed on the sonar display.

As the sonar sweeps from side to side, areas of shallower water will appear as solid targets and areas of deeper water will provide weaker targets or no targets at all. Any massive hard targets will be excellent sonar reflectors. In very shallow water, a tilt angle of between 0 and +4 degrees is very common.



PERIODIC MAINTENANCE

Safety Notes Ensure that the Sonar area (especially if located in a sealed tank in a ship’s double-bottom) is properly ventilated prior to entry for servicing. Observe all ship’s maintenance procedures and regulations. For example, obtain a tank entry permit prior to opening and entering confined areas.


Inspect Hoist Assembly for Signs of Corrosion The Zinc ring that protects the soundome tube should be inspected with every dry docking. The hoist assembly and hydraulic fittings should also be inspected for signs of excessive corrosion, especially for a system that is installed into a sealed tank where cold and condensation is typical.

Antifouling Paint WESMAR does not recommend painting the urethane plastic soundome boot. In the case of sand blasting operations on the hull adjacent to the seachest opening, it is strongly recommended that the seachest be temporarily covered to protect the soundome.

Check Hydraulic Oil Level The hydraulic system is tested and calibrated at the factory before shipping. They hydraulic system should not require additional oil at the time of initial installation. If the hydraulic lines (hoses) have been lengthened during the initial installation, the reservoir will require more oil.

The hydraulic hoists are self-bleeding. If air bubbles do get into the hoses, they will be expelled when the hoist has been raised and lowered several times.

Check the oil level after installation, and once a month after that, by removing the plastic thumbscrew venting plug on the side of the reservoir. Fluid level should be just below the opening.

Use Chevron Automatic Transmission Fluid, “Dexron® III”, or its equivalent.



Pour oil through a funnel until it begins to flow out the oil fill hole. Air will be able to escape out the vented thumb screw above. Replace the oil fill plug.

Check the Packing Gland for Leaks Check the hoist packing gland for leaks. Packing may need to be tightened, but if too tight may create excess friction on the soundome tube, and potentially stall the hoist motor. If the hoist motor is stalled, then fuses will be blown.

WESMAR has supplied an extra ring of flax packing which can be added subsequent to the initial installation if weeping is persistent.

Check for Chafing of Hydraulic Hoses and Electrical Cables Check hydraulic hoses and soundome cable in the vicinity of the Sonar hoist for possible snags and chafing during movement. It is prudent to wrap cables with anti-chafe protection.

All cables must avoid contact with limit switches during hoist movement. If hoses must be replaced, replace with Gates 6M3K (or equivalent) with JIC-6 (3/8”, 9.5mm) fittings.

Contact WESMAR for the most recent system software and documentation If software updates are available for the system they should be applied during dry-dock. Software updates are delivered as EPROM chips which should be removed using a PROM-puller tool as opposed to a screwdriver!

Inspect and clean the hoist assembly If the hoist assembly is located in a sealed area, it may have become dirty over time from condensation. Wipe the assembly with a degreaser such as Clorox 409 and clean rags. A clean hoist is easier to trouble-shoot in the future for signs of leakage, corrosion, etc.

Check the Electrical Boxes for loose connections, fuses and shorts Open up the Power Booster and Transmit/Receive Boxes and visually inspect them for signs of electrical problems. Ensure that appropriate spare fuses are taped to the inside of the boxes.



BASIC TROUBLESHOOTING Safety Notes Ensure that the Sonar area (especially if located in a sealed tank in a ship’s double-bottom) is properly ventilated prior to entry for servicing. Observe all ship’s maintenance procedures and regulations. For example, obtain a tank entry permit prior to opening and entering confined areas.


Cannot see any targets! PROCEDURE: Ensure that the wheelhouse monitor is turned on, and that power is available to the control unit.

PROCEDURE: Ensure that the unit completes its power-on self test and the system has started up normally. Ensure that power is available to the control and power boxes near the hoist.

PROCEDURE: Ensure that the range settings are appropriate for the location. If you are deep water, perhaps there is nothing to see. For navigation, the tilt of the transducer is set to zero (looking straight out, horizontally). Increase the far gains until targets appear. If all you see is red, then lower the gain settings until noise is removed.

PROCEDURE: Ensure that your color selection is appropriate. If you set the color of targets to the same color as the background, then targets won’t be visible.

Salt Water In the Soundome? PROCEDURE: Turn the console off and disconnect soundome cable Lugs #17 and #18 from the TR Box. Note, it is best to use an analog multimeter for this procedure. Measure the resistance between Lug #17 and Lug #18. If there is no water in the soundome, the reading should e Open (infinity). Salt water in the soundome will read between 1-3kΩ.

If water is in the soundome, the soundome must be replaced.

Seachest and hoist are Misaligned!



Hoist Packing Gland is weeping Water Excessively PROCEDURE: Ratchet the 2 large machine screws to tighten the flax packing gland cap down another revolution. If necessary, an extra layer of flax (supplied by WESMAR) can be added to the gland. Note: if the packing gland cap is tightened excessively, it can make it difficult to raise and lower the soundome, stalling the motor and blowing fuses.

Blinking lights on the wheelhouse panel console SAFETY NOTE: The hydraulic host is a fast-moving hoist. It should travel to any single limit switch in six seconds. Travel time can be longer depending on boat speed and the tightness of the packing gland.

If the hoist does not reach a limit switch in twenty seconds, the Red light on the control panel will start to blink. The hoist motor will continue for thirty seconds more. If no limit switch is triggered after thirty seconds, all three lights on the control panel will blink. The processor on the hoist board will turn the motor OFF.

PROCEDURE: If upper and lower hoist limit switches are not triggered fully into their movement, the hoist motor will continue to run until the system’s control software turns it off after 20 seconds. The limit switches can be adjusted higher or lower by loosening and then re-tightening their respective Philips-head machine screws on the hoist assembly.

PROCEDURE: Ensure that the tube clamp guide has been securely tightened just below the 3 hex bolts that secure the hydraulic assembly to the soundome tube. If the guide is secured too low, the limit switches will not be engaged fully at their factory settings.

Hoist Motor runs but Hoist will not Raise or Lower PROCEDURE: Check that the ATF fluid in the hydraulic reservoir is not too low. Refill with an appropriate ATF.

PROCEDURE: The packing gland cap is too tight. It should be tightened so that the gland weeps a little water, but not over-tightened.



PROCEDURE: Verify that the sea chest opening is not obstructed.

PROCEDURE: Ensure that the metal shipping screw in hydraulic oil reservoir has been replaced in the field with the pressure-relieving (1500 psi) plastic thumb screw.

Soundome will not stay up PROCEDURE: Check for a leak in the hydraulic cylinder. If hydraulic hoses have been disconnected for servicing, secure the soundome tube to the hoist cross-members to ensure that it will not drop.

Hoist Motor will not Start PROCEDURE: Check that the hoist fuse in the Transmit/Receive Box has not blown. For a 110 VAC system, this will be a MDL 30Amp Slo-blow. For a 220 VAC system, this will be a MDL 20 Amp Slo-Blo. Always keep a few spare fuses taped to the inside of the T/R Box.

PROCEDURE: Check that the circuit breaker that provides power to the Hoist System and Electronics has not been tripped. Once the power is re-energized, the hoist tub may jump up if the top limit switch is not triggered. Once triggered, the motor will stop running.

LINK on Sonar Display fails to turn GREEN during Power-on Self-Test (POST) PROCEDURE: Ensure that the AC breaker to the Transmit/Receive and Power Boost boxes is ON.

PROCEDURE: Verify that the Interconnect cable between the Transmit/Receive Box and the Computer Control Unit in the wheelhouse has not been damaged. Check any intermediate Junction Boxes for continuity and secure connections..

Sonar Noise Check WESMAR sets the internal gain of the receiver in our test tank. For installations where the 860 is located in a vessel’s engine room, it is prudent to compare the receiver gain to the noise generated by the vessel.

For larger ships, where the Sonar has been installed in a tank, noise is not usually an issue.



To evaluate noise levels, adjust the Sonar to the following settings:

MENU WESMAR 860 SONAR PROFILE COLORS LOCAL

SETTINGS

Range = 100

Tilt = 0

Center = 0

Sector = 360

Speed = 1

Cursor = 1

Text = 1

Units = Meters

NOTE: A pulse-width of Zero configures the Sonar for Passive Mode (Listening only). Don’t forget to set Pulse to a non-zero value after the noise check is completed otherwise you won’t see any targets.

With the vessel out of gear and no headway, or at dockside, there should only be light sprinkle of blue dots on the last 2/3 of the screen. Move ahead slowly. There should be the same, light sprinkle of blue dots.

Speed up to five knots. There should be no change. Keep increasing speed up. At some speed , noise will come into the display. If this speed is exceeds the intended use of the sonar, then the noise test is complete.

Noise can make the screen all red. One can reduce the gains to remove the red; however, sonar range will suffer. The only way to remove the unwanted noise is to locate the source. Noise can come from:

1. Electrical; generators, converters, motors, etc.

2. Mechanical; machinery, hydraulics, shaft bearings, reduction gear, motor vibration..

3. Flow noise; water running under the vessel, aeration across the soundome, cavitation and rough seas.

Seachest Specifications The HD860, (160, 110, or 60 kHz) depending on the model, will an 8-inch soundome. The size of the soundome will determine the pipe and the flange specifications. Use one of the included drawings when fabricating the seachest at the boat yard. Steel and wooden boats use steel. Aluminum boats use aluminum. Fiberglass boats use fiberglass. Fiberglass seachest with flange can be ordered from WESMAR. (8-inch Part #62.04329.0)

8-inch seachest 1. Use 8-inch Schedule 80 steel pipe (7.625 in ID nominal) 2. Length between minimum (3.2.1) and 40 in (1.2 m) CALL FACTORY 3. Paint inside with same bottom paint as hull.

ELECTRIC HOIST INSTALLATION

Note: The HD860 can be ordered with an electrical hoist or a hydraulic hoist.

Calculate Length of Soundome Tube for Lead Screw Hoist

For electric lead screw hoist (12 or 24 VDC):

8-inch soundome: measure the length of the seachest and add 8 inches (20.32 cm)



When the proper length of the soundome tube is determined, measure from the threaded end, mark the length and cut. File the rough edges.

Check soundome clearance inside seachest

The soundome should not fit tight inside the seachest. This can place additional strain on the hoist motor and damage it. Also, if the insides of the seachest start to rust the dome may jam and possible damage to the hoist motor may result. A loose fitting soundome will be subject to vibration reducing sonar performance.

The HD860 soundome must fit the seachest with a clearance no greater than 1/16 inch (1.6 mm).

When checking the soundome, do not handle the soundome by the soundome cable. Hold the dome by the neck.

Fasten the soundome to the soundome tube

1. Thread the jam nut into the soundome.

2. Wrap Teflon tape around the threads of the soundome tube. WARNING: only use Teflon tape on the threads of the soundome tube.

3. Run the soundome cable all the way through the soundome tube, starting from the threaded end. Have a helper hold the soundome at the same time rotate the soundome tube. Be careful not to cross threads. Tighten by hand without tools.

4. Tighten the jam nut using a wrench for a snug fit.

5. To protect the soundome cable from chafing on the end of the soundome tube, a urethane strain relief is supplied. Cut the urethane strain relief down one side. Open the cut and push the soundome cable into the strain relief. Slide the strain relief down the cable and into the open end of the soundome tube.

Urethane Guides

Wesmar supplied lock nut, zinc and urethane guides need to be installed before soundome goes into seachest (see photo to the right).



Assemble Hoist

1. Remove the packing flax from the packing gland on the flange.

2. Run the soundome cable through the flange following by the soundome tube. Insert the packing flax one at a time. Use a 1/4-inch (6 mm) rod to push the flax to the bottom of the packing gland. Rotate the next flax by 90 degrees and push to the bottom. Do the same for the remaining flax, total six pieces. Slide the packing gland cap over the soundome tube. Apply ANTI-SEIZE (supplied) to the thread posts. Thread the two nuts on each cap post DO NOT tighten the 7/16-inch nuts.

3. Thread the top hoist clamp onto the lead screw until it is flush with the top.

Use alcohol to clean soundome tube and grip area of upper hoist clamp. Rough surface of soundome tube where the clamp will be fastened with 100 G sandpaper as well as the grip area of the hoist clamp. Use caution not to over tighten bolts. Use anti-seize on bolts as instructed.

4. Apply ANTI-SEIZE to the bolts on the safety clamp and top hoist clamp. Slide the safety clamp over the soundome tube. DO NOT tighten. Push the soundome tube through the top hoist until 2 inches (51 mm) remain on the other side. Tighten the top hoist clamp (3/8 inch nuts) so the soundome tube is locked in place.

5. Place safety clamp directly below the top hoist clamp and tighten bolts.

Attach Hoist to Seachest

1. The soundome has the letters FWD stamped on the edge of its stainless steel top. Locate this mark and make a new mark on top of the soundome tube in line with the FWD stamp. This mark will be the reference point that points to the bow.

2. Clean the flange surface of both hoist and seachest. Place the clean neoprene gasket on

Thoroughly grease leadscrew before use.



the seachest flange. There is no need to grease the gasket. Carefully lift the hoist and align the soundome to the opening of the seachest. Lower the hoist onto the seachest. Rotate the hoist for easy access to the TR box. Apply ANTI-SEIZE (supplied) to the 1-inch bolts (supplied). Insert the 1-inch bolt from the bottom up. Use the lock washers and nuts (supplied) to tighten the hoist flange to the seachest.

3. Align the soundome to the boat, FWD to point toward the bow of the vessel.

4. Check the soundome inside the seachest. The hoist is shipped from WESMAR in the up position. The above procedure will place the soundome 1.5 inches (38 mm) inside the seachest. If the boat is out of the water, check this distance. To make corrections, loosen the top hoist clamp and push up or down on the soundome tube for the correct measurement. Retighten the hoist clamp.

5. Slide the safety clamp up to the top hoist clamp. Apply ANTI-SEIZE to the bolts and tighten. WIRING All hoist motor cables are numbered and are installed on mother board in transmit box. (All cables are numbered for easy assembly and installation.) Any questions, please contact factory.

Check hoist travel distance travels beneath the keel.

To make corrections loosen the top hoist clamp and safety clamp. Move the soundome up or down for the correct position.

Packing Gland Tighten the packing gland by rotating the two nuts hand tight then two complete turns using a wrench. Tighten the second nut against the first nut.

Lead Screw Hoist



When the boat is back in the water, cycle the hoist up and down four times. Check the packing gland for water. It is normal for the packing gland to be wet but not dripping with water. Retighten the nuts on the packing gland. WARNING: Do not tighten the packing gland too tight. A tight packing gland will hold the soundome tube from moving, either the fuse will blow or the bronze shear pin will break.

HYDRAULIC HOIST INSTALLATION Install the soundome

1. Clean the mating surfaces of the soundome and soundome tube flange.

2. Run the soundome cable through the flange O-ring then through the soundome tube so there is 1 foot (30 cm) slack at the dome end.

3. Apply silicone compound to the O-ring. Position the O-ring in the machined groove on top of the soundome.

4. Use ANTI-SEIZE and bolt the soundome to the soundome tube and tighten.

5. FWD (Forward Arrow) depicts direction forward. Mark top of soundome tube for reference of forward arrow.

Install the hydraulic ram

1. Remove the top cross plates from the rack assembly. Note which plate is connected to which rack. Make sure the tube guide clamp does not slip off the soundome tube when removing the cross plates.



2. Remove the cable strain relief from the hydraulic ram end cap.

3. Place the soundome cable in the slot on the hydraulic end cap. Slide the hydraulic ram inside the soundome tube. The ram can be disconnected from the hydraulic power pack by using the quick disconnect fittings at the end of the hydraulic lines. Align the soundome cable coming through the end cap with the rack leg that has the limit switches. The cable will be to the left and the limit switches to the right. Push the hydraulic ram in place. Align the holes in the soundome tube with the holes in the ram end cap. Slide the tube guide clamp up over the aligned holes. Bolt all three pieces together. Before tightening visually draw a line from the packing gland bolt and the bolt just installed. Rotate the soundome tube so the two bolts are in line with one another. Tighten the two bolts. Do not tighten the packing gland bolts at this time.

4. Place the strain relief grommet around the soundome cable. Slide the grommet down the cable until it fits snuggly into the top of the hydraulic end cap. Bolt the strain relief plate over the grommet.

5. Push the soundome tube up until the hydraulic ram shaft goes through the holes in the center of the cross plates. Thread the castle nut onto the ram shaft so it’s snug; at the same time align the holes through the shaft with the nut. Place a cotter pin through the hole and lock it in place.

INSTALLATION

Install hoist assembly on seachest

Placing the hoist assembly on the seachest will require the assistance of two or three helpers. Use a chain fall connected to the overhead to lift the load.

1. If the hydraulic lines are removed from the ram end cap, the fittings may leak when the hoist



is lifted up. To reduce leaking, install the safety clamp around the soundome tube just above the packing cap and tighten in place. This will keep the soundome tube from slipping down when lifting the hoist.

2. Clean flange surfaces of the seachest and hoist. Place the neoprene gasket on the seachest flange.

3. Lift the hoist assembly and set it on top of the seachest. Rotate the flange to coincide with the hoist power pack and limit switches for easy maintenance.

Alignment considerations:

a) Only DC power pack can be installed on the hoist rack. The rack opposite the limit switches is the only rack leg the power pack can be attached to.

b) The AC power pack must be installed on a bulkhead. The DC power pack can also be installed on a bulkhead and not on the rack. Rotate the hoist so the rack leg with the limit switches is adjacent to the bulkhead that has the power pack. This will avoid crossing the hydraulic lines.

4. Bolt the hoist flange to the seachest. Apply ANTI-SEIZE on the bolt threads. Insert the bolts from the bottom up. Use the lock washer and nuts and tighten in place.

5. Tighten the packing gland cap bolts finger tight. Use wrench and tighten each bolt one full turn, repeat for a total of two turns.

NOTE: When the vessel is back in the water, cycle the hoist up and down four times. Check the packing gland for water. It is normal for the packing gland to weep but not drip. Tighten if necessary.

Install hydraulic power pack

1. Install the DC power pack on the rack leg opposite the leg with the limit switches. Half way up on the leg are two holes for bolting the DC mounting bracket.. Use ANTI-SEIZE and tighten in place. Connect the hydraulic lines to the cylinder.



2. Install the AC power pack to the bulkhead. Use the mounting bracket attached to the motor. Generally taped standoffs are welded to the bulkhead and the motor will bolt to them. The hydraulic lines will need to be lengthened. Make sure there is enough slack in the lines for up and down travel. Connect the hydraulic lines to the cylinder.

3. After the hydraulic lines are connected make sure they are free to travel and no chance to catch on nonmoving part. The soundome cable must also be free to travel and not catch on any nonmoving part.

4. Install the vent screw in the reservoir. In order to ship the hydraulic power pack full of oil, the vent screw was replaced with non-venting screw. This non-venting screw must be removed and replaced with the supplied venting tape.

WIRING, DC HYDRAULIC HOIST

The DC hydraulic hoist is a stand-alone system that does not require power from the sonar. It will operate on its own. The hydraulic power pack is available in 12 and 24 VDC. Wiring is different between the two voltage systems.

Check the voltage of the hydraulic pack unit before wiring.

DC hoist board wiring

1. The DC hoist board is enclosed in its own aluminum box. The DC hoist board will work on both 12V hydraulic power pack units and 24V hydraulic power pack units.

2. Hoist control cable, PN: 78.10015.0

The hoist control cable is 25-feet (7.6 meters) long. One end is terminated with a six pin connector, the other end is terminated with terminal lugs. The connector end will mate with the connector



on the switch panel in the wheelhouse. The other end will go through a strain relief fitting on the hoist control box and connect to terminal TB1, number to number.

If a longer hoist control cable is needed, hoist extension cables are available in 25-foot (7.6 meter) lengths, PN: 78.10015.1

3. Hoist board voltage

Voltage to the hoist board must be the same as the voltage for the hydraulic power pack. This voltage powers the solenoid valve, the big relay on the DC motor, the up/down relays on the hoist board and the red and green lights on the switch panel in the wheelhouse. The hoist board is fused with a 5A slow blow fuse. Run ships power through a strain relief fitting on the hoist box and connect the battery negative to terminal #31 and battery positive to terminal #30. Use the correct wire size to carry 5 amps over the distance from battery to hoist board.

4. Solenoid valve wiring

The large relay on the DC motor is activated by the same voltage that operates the solenoid valve. To simplify wiring, the relay is pre-wired into the solenoid valve. From the solenoid valve there is a pre-wired cable with numbered lugs at the end. Pass the cable through a strain relief on the bottom of the hoist box. Connect the wires to TB2, number to number.

5. Limit switch up/down wiring

Located on the hoists are two limit switches that will stop the hoist at its up and down limits. Both switches are pre-wired and numbered at WESMAR. Run the limit switch wires through a strain relief on the hoist box. Connect the wires to TB2, number to number.

6. DC motor wiring

The hydraulic power pack is available in 12V and 24V. Confirm the voltage of your unit before wiring. The 12V motor will draw 65 amps under normal load. The 24-volt motor will draw 40 amps under normal load. The amperage will go up if resistance in hoisting increases. Fuse the 12-volt motor for 130 to 140 amps. Fuse the 24 volts for

Hydraulic Hoist Assembly



to 60 amps. Select a wire gauge appropriate for the load. The hoist takes less than ten seconds to go up or down so the cycle is very short before it turns off. Wire as pictured on Page 34.

WIRING, AC HYDRAULIC HOIST

The AC wiring hoist is a stand-alone system that does not require power from the sonar to operate. It will operate independent from the sonar. The hydraulic power pack is available as 110V AC single phase and 220V AC single phase. Wiring is the same for both systems.

AC hoist board wiring

1. The AC hoist board is enclosed in its own aluminum box. Before wiring, check the AC voltage of the board. Next to transformer T1 there will be one or two jumpers installed. One jumper is for 220V AC and two jumpers are for the 110V AC

NOTE: Use a 30 amp slow blow fuse for 110V AC and a 20 amp slow blow fuse for 220V AC.

2. Hoist board voltage.

Voltage to the hoist board is the same voltage that will power the motor and the solenoid valve on the hydraulic power pack. Run ships AC power through one of the strain relief fittings on the hoist box and connect the wires to TB3. Use wire size capable to handle a one horsepower motor.

3. Hoist control cable, PN: 78.10015.0

The hoist cable is 25 feet (7.6 meters) long. One end is terminated with a six pin connector; the other end is terminated with terminal lugs. The connector will mate with the connector on the switch panel in the wheelhouse. The other end will go through one of the small strain relief fittings on the hoist control box. Connect each number wire to the same numbered terminal



on TB1. If longer hoist control cable is needed, hoist extension cables are available in 25 foot (7.6 meters) lengths. PN: 78.10015.1.

4. Solenoid valve wiring

The solenoid valve is pre-wired with terminal lugs at the ends. Run the solenoid cable through one of the strain relief fittings on the hoist box. Connect the wires to TB2, number to number.

5. Limit switch up/down wiring:

There are two limit switches on the hoist rack that will stop the hoist at the travel limits. Both switches are pre-wired with terminal lugs at the ends. Run the limit switch wires through one of the strain relief fittings on the hoist box. Connect the wires to TB4, number to number.

OPERATION CHECK, HYDRAULIC HOIST, DC & AC

Lowering hoist first time

1. Check to make sure there is enough room beneath the boat before lowering the soundome. Total travel is 18 inches, 45.5cm. Outside the seachest 16.5 inches, 42cm.

2. Make sure the hoist switch is in the ‘up’ position.

3. Disconnect the upper hoist limit switch wire labeled #27 located on TB2 for DC motors or TB4 for AC motors. Once this wire is disconnected the hoist will only move down when powered.

4. Disconnect the hoist down limit switch wire labeled #1 located on, TB1 for DC motors and TB1 for AC motors. Once this wire is disconnected the hoist will not move when the hoist switch in the wheelhouse is pushed down to lower the soundome.



5. 1. The hoist will lower. The hoist should stop before the safety clamp comes in contact with the packing gland. If it looks like the safety clamp will come in contact with the packing gland remove the wire immediately. Tap the wire on terminal #1 for short movements until the hoist stops. The top clamp should stop no less than 0.5 inches, 13mm above the packing gland.

Adjustment - Move the lower limit switch up on the hoist rack so the top clamp is 0.5 inch, 13mm to 1.0 inch, 25.5mm above the packing gland

6. Lift up the soundome - Push the hoist switch up in the wheelhouse. Touch the wire labeled #27 to terminal #27. The hoist will start to go up. The hoist should go up, stop and the motor turn off.

Adjustment - If the motor keeps running when the hoist has stopped in the up position the top limit switch must be lowered. Lower the limit switch so the hoist will stop 0.5 inch, 13mm before the mechanical stop.

7. Connect the wires back to terminal #27 and #1.

Check hoist soundome travel

1. Lower the soundome, push the hoist switch down in the wheelhouse.

2. Measure the distance from the bottom of the seachest to the bottom of the soundome under the boat. The distance should be 16.5 inch, 42mm to 15.5 inch, 39mm.

Packing Gland

1. Tighten the packing gland by rotating the two nuts hand tight then two complete turns with a wrench. Tighten the second nut against the first nut to lock.

2. When the boat is back in the water cycle the hoist up and down four times. Check the packing gland for water. It is normal for the packing gland to be wet but not dripping with water.



3. Retighten the nuts if water drips after cycling the hoist. WARNING: Do not tighten the packing gland too tight. A tight packing gland will hold the soundome tube from moving and may trip the circuit breaker or damage the electric motor.

4. From time to time inspect the packing gland. Tighten if needed.

HYDRAULIC HOIST TROUBLESHOOTING 1. ‘Up’ and ‘Down’ are reversed:

a. Solenoid valve is wire opposite. b. Hydraulic lines are reversed.

2. Hoist motor runs, green light on, but will not raise or lower.

a. Solenoid valve stuck. b. Check solenoid wiring. c. Fluid level in reservoir is too low. d. Packing gland cap is too tight. e. Hoist rack is bent. f. Obstruction in seachest. g. Reservoir is not vented. 3. Hoist motor continues to run, green light on, hoist did go up & down.

a. Limit switch arm not triggering. b. Soundome tube not traveling all the way. c. Broken wires to limit switches. d. Reservoir low on fluid.

4. Soundome tube will not stay up.

a. Dirty check valve. b. Leak in hydraulic lines. c. Leak in hydraulic cylinder.
