DensityPRO Chapter 1 Introduction

Chapter 1 Introduction

The Thermo Scientific DensityPRO gamma density system is designed to provide reliable, accurate process material density measurements for a wide variety of challenging applications. The gauge is mounted outside of the process vessel and never contacts the process material. The instrument can measure the density of almost any liquid, slurry, emulsion, or solution.

The instrument can convert the basic density measurement into a variety of output measurements as appropriate for specific applications, e.g., bulk density or solids content per unit volume. Given a temperature input, the instrument can compensate the density measurement relative to a user-specified reference temperature. If a flow input is provided, the instrument can calculate mass flow. The Setup Menus guide you through the configuration process to help you quickly complete the gauge setup.

Description

The gauge consists of the source head that contains the radioisotope source and the detector-transmitter that contains the scintillator detector and electronics. The radioisotope source emits gamma radiation that passes through the process material. The detector measures the energy of the radiation arriving at the detector after passing through the process material (and vessel walls). The gauge determines the density of the process material by measuring the amount of radiation arriving at the detector, which varies with the density of the process material.

Detector-Transmitter Source

Approvals

The instrument is certified for use in hazardous locations by FM/CSA as follows.

Model 9719A Detector

• Class II, III, Div. 1, Groups E, F, G • NEMA 4 / Type 4


• Class I, II, III, Div. 1, Groups B, C, D, E, F, G • NEMA 4 / Type 4

Note: Refer to the tag on your gauge to verify the hazardous location approval information for your gauge.

Chapter 1 Introduction DensityPRO

Source

A Cesium (Cs-137) radioisotope source is used for most applications. A Cobalt (Co-60) source is available for applications requiring a higher energy source. The radioisotope is bound in ceramic pellets and double-encapsulated in a pair of sealed, stainless-steel containers. The resulting source capsule is highly resistant to vibration and mechanical shock.

The source capsule is further enclosed in the source head, a lead-filled, welded steel housing. A shaped opening in the lead shielding directs the gamma radiation beam through the process material towards the detector. Outside of the beam path, the energy escaping the source head is very low and well within prescribed limits. Closing the source shutter allows the beam to be “turned off” (the shutter blocks the radiation) during installation or servicing of the gauge. All source housings meet or exceed the safety requirements of the U.S. Nuclear Regulatory Commission (NRC) and Agreement State regulations. Refer to the Gamma Radiation Safety Guide (P/N 717904).

Detector-Transmitter

The gauge uses a scintillator-type detector to measure the radiation reaching the detector from the source. The detector consists of a special plastic scintillator material, a photomultiplier tube, and associated electronics. When radiation strikes the plastic scintillator material, small flashes of light are emitted. As the density of the process material increases, more gamma radiation is absorbed by the process material and fewer light pulses are generated by the scintillator material. A photomultiplier tube and the associated detector electronics converts the light pulses into electrical pulses that are processed to determine the process material density and related measurement values.

Measurement Calculation

After the gauge calculates the process material density, it can convert the measurement into a number of forms. For a slurry (solid material in a carrier fluid), the gauge can provide measurements based on the ratio of solids to carrier. Similar measurements can be made for emulsions (two different fluids) and for solutions (a solute material dissolved in a solvent fluid).

If flow data is provided as an input, the gauge can generate mass flow measurements. A 4-20 mA current output from a magnetic flow sensor or from a Thermo Scientific VersaFLO™ fixed or portable flow meter can be input to the instrument.

For applications that require temperature compensation, the gauge can accept a temperature input to compensate the density measurement for changes in process temperature.

Communications and Measurement Display

You communicate with the gauge via the RS-485 or the RS-232 serial ports from a Thermo Scientific Hand-Held Terminal (HHT), a PC running TMTComm for Windows® or terminal emulation software, or a standard ANSI or VT-100 terminal.

1-2 Thermo Fisher Scientific


The HART communication protocol is supported over the 4-20 mA current output with an optional daughter board. You communicate with the gauge using the standard Fisher Rosemount 275 HART handheld communicator. Refer to the “DensityPRO/ DensityPRO+ HART Operation Manual,” (717816), for detailed instructions.

Once the gauge has been set up, the primary (density) measurement is displayed on the external display, if present, and on the remote terminal or HHT.

Chapter 1 Introduction DensityPRO

Features

Dynamic Menu System

The Setup Menus guide you through the configuration of the gauge. The “Set up density, den. alarms, and flow” menu group includes all of the basic parameters and commands required to quickly configure your gauge. Additional menu groups provide specialized parameters and commands allowing the gauge to be tailored to a wide variety of applications.

Direct-entry menu shortcuts are also provided, allowing experienced users to access menu items and commands directly, bypassing the menu system.

Instantaneous Response

Our Dynamic Process Tracking (DPT) ensures that there is no lag time in the system response to significant changes in process density. When changes occur, the DPT feature reduces the normal averaging time constant by a factor of eight, ensuring a rapid, yet smooth output response. When the process stabilizes, a longer time constant is applied to reduce the fluctuations inherent in radiation-based measurements. In this way, process density changes are immediately reflected in the transmitter output, while the effects of statistical variations in the radiation measurement are greatly reduced.

Multiple Readouts

Select up to eight measurement values for display. Available measurement types include density, bulk density, solids concentration, carrier concentration, ratio of solids to carrier, bulk mass flow, bulk volume flow, and the rate of change of any these measurements.

Extensive Alarms

You can set up as many as 16 process alarms in addition to system fault alarms and warning alarms.

Totalizers and Batch Control

You can set up four independent totalizers to “count” elapsed time or cumulative mass/volume when a flow input signal is provided and a mass/volume-flow measurement has bee defined. Totalizers can be assigned to drive relays. Relays can be set to open or close at specified “slow” and/or “stop” counts for batch or sample control.

Output Signals

You can assign any measurement to the 4-20 mA current output, or the measurement values can be sent to a remote terminal or host computer as serial data. The two contact closure inputs can be used to activate any system command based on a user-provided switch input (open or close). Two relay outputs are available on the optional AC power/relay board.

Chapter 2 Hardware Installation DensityPRO

Mounting the Gauge (Source and Detector-Transmitter)

Mounting Configurations

The optimum gauge mounting configuration depends on the application; however, the source head and the detector are typically mounted together on the opposite sides of a pipe. The following mounting options are supported for the instrument:

• Chain mount − Single chain (unichain) − Dual chain

• Cradle-type (saddle) clamp • Pipe spool with gauge head pre-installed • Z-pipe (axial) mount for small diameter pipes

The chain mount is the most frequently used mounting configuration this allows the unit to be mounted on a range of pipe sizes using the same mounting hardware.

Note: Moving the gauge to a pipe with a different diameter may require changing the radiation source size. Call Thermo Fisher for assistance.

Guidelines for Mounting the Gauge • Power requirements for the detector-transmitter:

− 24 Vdc ±20%, 12VA, at detector input, or − 12 Vdc ±30%, 12VA, (w/12-to24 Vdc converter option), or − 115/230 Vac (±15%), 50/60 Hz, 12 VA (w/AC Power option).

• The operating temperature range is –40º C to 70º C (–40º F to 160º F). • Make sure there is enough clearance to install and service the gauge head. (Refer

to the appropriate drawings for your type of gauge and mount.) • Position the gauge head so the radioactive source identification tag is visible.

Mount the source housing so the tag is upright. • Avoid locations where process overflow, debris, or other material can collect in

the beam path (especially in the shutter mechanism).

Regardless of what mounting configuration is used, it is important to align the beam path (the centerline of the source housing) as closely as possible with the centerline of the detector housing. Be sure to mount the gauge head securely, since any movement or change in alignment can affect the gauge’s calibration.

For best performance the beam must pass through a representative cross-section of the process material being measured.

• It is best to mount the gauge head on a vertical section of pipe. This keeps suspended solids from settling out of the measured area. (The gauge measures only the material that passes through the beam.)



• To mount the gauge head on a horizontal pipe – − Position the beam path at a 30 to 45 degree angle from vertical. This position

tends to average density variations caused by settling, while reducing the effect of any trapped gases or solids that accumulate in the top or bottom of the pipe.

− If the process material is a solution, light slurry, or a single-phase liquid that will not separate, the gauge head can be mounted such that the beam is horizontal.

• If the process material is a slurry, position the gauge head as far as possible from any elbows, tees, or valves - these tend to separate suspended solids. Position the beam path in the plane of the upstream elbow so the measurement includes any uneven distribution caused by the fitting.

Mounting Instructions

The following sections provide installation details for the various mounting configurations.

Refer to the following drawings for detector dimensions.

• Drawing 866778 Model 9719A detector (NEMA 4 Housing) • Drawing 866777 Model 9720A detector (Exp-Proof Housing)

Caution: Use proper lifting procedures during installation to avoid injury.

Do not over-tighten the bolts.

Single Chain (Unichain) Mounting Instructions

The single chain or unichain mount is only available with the Model 5211 source housing. In this mounting configuration, a mounting chain is inserted through an eye bolt in the rear of the source housing. The two ends of the chain are wrapped around the pipe and engaged in slotted tabs in the detector housing.



The following steps describe the installation of the gauge head using a single chain mount. Also refer to the following drawings for mounting details.

• Drawing 867456 Model 9719A detector (NEMA 4 housing), or • Drawing 867465 Model 9720A detector (explosion-proof housing).

The mounting hardware kit shipped with the gauge should include:

− 1 Eye Bolt (.500-13 x 3 in.), 1 Nut (.500-13), 1 Belleville Washer − 1 Chain

1. Insert the eye bolt through hole in rear of source housing. Place Belleville washer, cupped-side first, onto the eye bolt. Thread the nut on the eye bolt until the bolt just begins to come through the nut.

2. Insert the chain through the eye bolt so that approximately the same length of chain extends on each side of the eye bolt.

3. Position the source housing and detector housing so that the V-shaped mounting features center the housings on the pipe.

4. With the axis of the source housing and detector housings aligned, attach one end of the chain in the slotted tab on one side of the detector housing. Pull the chain tight on the other side and attach it into the slotted tab on the other side of the detector housing.

5. Maintain alignment of the housings and tighten the nut on the eye bolt ~1/2 turn past point where Belleville washer becomes fully flattened.

Note: There must be an even number of chain links between the slotted tabs so that there will be an equal number of links on both sides.

Dual Chain Mounting Instructions

In the dual chain mount, two mounting chains are wrapped around the pipe with their ends engaging keyhole-shaped openings in the source head mounting plate. The detector housing is then clamped to the two chains’ center links (opposite the source mounting plate) by tensioning bolt assemblies as illustrated in the photograph below.



The following steps describe the installation of the gauge head using a dual chain mount. Refer to the following drawings for mounting details.

• Drawing 867466 Model 9719A detector • Drawing 867467 Model 9720A detector

1. Use the table on page 2-6 to determine the number of chain links to thread

through the keyhole slots. Count the links and mark the links that will be engaged at each end of the two chains (four links in all).

2. Partially assemble the two tensioning bolts (hardware kit 885826) in the following order: − 1 tensioning bolt (large), − 1 chain - place center ring of chain over the bolt head, − 1 bar nut - position the guard tube towards the bolt head, − 1 special nut - thread nut securely onto the bolt end. After the special nut is

fully threaded, thread the bar nut back down the bolt so that it rests against the special nut.

3. From the pipe side of the source mounting plate, thread one end of a chain through the plate’s top keyhole opening until you reach one of the four end links you marked in Step 1. Engage this link by sliding it into one of the keyhole slots.

4. Thread one end of the other chain through the bottom keyhole and engage the marked link as you did with the top chain.

5. Position the source housing mounting plate on the pipe. If necessary, use a lift, hoist, or other means to hold it in position.

6. Pass the center part of the upper and lower chains around the pipe and thread their ends through the corresponding keyholes. Engage the marked links in the empty slots.

Note: All four chain ends must engage at the same link. To make an adjustment, adjust all four chain ends by the same amount. Make sure the chain does not twist as you wrap it around the pipe. You may have to adjust chain links (thread more or fewer links through each slot) to allow for pipe size tolerance, insulation, and so forth. Start with about 10 cm (4 inches) of play.

7. Position the detector on the pipe, opposite the source mounting plate. If necessary, use a lift, hoist, or other means to hold it in position.

8. To secure the detector and the source head mounting plate on the pipe: − Position the upper chain (including the tensioning bolt assembled in Step 1)

over the detector’s top mounting arm. − Place a spacer ring and then two Belleville washers (concave sides together)

onto the pilot end of the special nut. − Insert the pilot end of the chain tensioning bolt into the hole in the top

detector mounting arm and tighten the chain tensioning bolt finger-tight. − Repeat the previous three steps for the lower chain.

9. Alternately and uniformly tighten the chain tensioning bolts until the spacers are just touching the mounting arms.



10. Place the loose ends of the upper chain over the top edge of the source mounting plate so they won’t interfere with the source housing installation.

11. Position the source housing so its four mounting holes engage the four studs on the mounting plate. If necessary, use a lift, hoist, or other means to hold it in position.

12. Use the provided lock washers and nuts to secure the source housing.

Pipe Saddle (Cradle) Mounting Instructions

A pipe saddle mount (shown below) is a pair of identical mounting plates that are bolted together on opposite sides of the process pipe.



Refer to drawing 85726N and use the following steps to install a gauge head with a pipe saddle mount:

1. Assemble the two halves of the saddle mount onto the process pipe using the supplied nuts, bolts, and washers. Do not tighten the nuts and bolts yet, just thread them together.

2. Adjust the saddle mount halves so the mounting plates are parallel and even with each other. Then tighten the bolts evenly so the clamp ends are the same distance apart on both sides of the pipe.

3. Bolt the detector and source housings to the mounting plates on either side of the pipe saddle.

4. Tighten all bolts securely so the gauge head components cannot shift positions.

Pipe Spool Mounting Instructions

A pipe spool is normally a 30-inch section of pipe with either mounting plates or a complete gauge head already installed. Often, the customer sends a length of the required pipe to Thermo Fisher to be converted into a pipe spool mount.

Warning: Use correct pipe fitting techniques suitable for the pipe being used and the process material that the pipe will handle.

Use the following steps to install a gauge head with a pipe spool mount:

1. Assemble the pipe spool into the existing pipe. 2. Position the source housing so its identification tag is upright. 3. If the detector and source housings are not already installed, bolt them to the

mounting plates on either side of the pipe saddle. 4. Tighten all bolts securely.

Z-Pipe (Axial) Mounting Instructions

A Z-pipe mount is used for small pipes, four inches in diameter or less. It uses a Z-shaped pipe section so the gamma rays can travel along the pipe’s axis for several inches. This lets the beam pass through more process material so the material’s density can be measured more reliably.

Depending on the application, the user typically fabricates the Z-pipe section and then either assembles it into the mounting fixture or sends it to Thermo Fisher for assembly.

Fabricating and Assembling the Z-Pipe

To fabricate the Z-pipe, refer to the drawings for your specific application.

• Drawing 861104 Z Pipe Fabrication Details (1-3 in. pipe sizes) • Drawing 864163 Z Pipe Fabrication Details (4 in. pipe)

Carefully note the tolerances for each dimension. Any variation in the Z-pipe dimensions, especially in the bracket placement, can lead to misalignment causing inaccurate readings or no readings at all.



Z-Pipe Installation

Refer to the following drawings for mounting dimensions.

• Drawing 866670 Z Pipe Mount (1-3 in. pipe sizes) • Drawing 864163 Z Pipe Mount (4 in. pipe)

Caution: If a lead doughnut is provided with the mounting assembly, make sure

its inside diameter matches the pipe’s outside diameter.

While assembling the mount, clamp the doughnut to the axial portion of the Z-pipe (between the source and detector) as close to the center as possible.

Warning: If the process pipe is not strong enough to support the gauge head and mounting assembly, you must provide additional support for the gauge head.

After the pipe and mount are assembled, you can install the gauge head using the steps in “Pipe Spool Mounting Instructions” on page 2-7, with the following additional notes:

• If your gauge is supplied with a large lead plate with a one- to two-inch hole in the center, the plate should be mounted between the detector and the mounting plate.

• If your gauge is supplied with a thin steel plate with a small lead disk, the plate should be mounted between the source housing and the mounting plate, with the disk towards the pipe (the disk should fit in the hole in the mounting plate).

Chapter 3 Wiring Procedures DensityPRO

Wiring Drawings

The Installation Layout drawing (868580) provides general guidance for routing the cables to the unit. The installation wiring drawing (868578) describes the function and wiring requirements for each connector on the CPU/DC power board and on the optional AC power/relay board. The wiring drawing also shows cable requirements, power requirements, and grounding locations.

The wiring label on the top of the detector-transmitter chassis also provides connector wiring information for the CPU/DC power and the AC power /relay boards. Drawing 868519 provides additional instructions for wiring the RS-485 serial port.

Initial Wiring Preparations

Warning: Do not apply power to the unit in any hazardous area unless the safety ground is properly wired inside the unit and the cover is properly installed.

Note: Connect the AC wiring Earth ground to the internal safety ground terminal as shown in the wiring diagram. Refer to “AC Power” on page 3-3, if you need to change the AC supply voltage from 115 V to 230 V or vice versa.

Warning: Hazardous Location Installations – The cable entries must be sealed per the Installation Layout Drawing (868580).

Non-Hazardous Location Installations – The cable entries into the enclosures must be sealed to prevent passage of gas or vapors. The sealing compound should not be affected by the surrounding atmosphere or liquids. The minimum thickness of the sealing compound should be 5/8 in (16 mm).

If metal conduit is used, the conduit must be grounded.

Use the following procedure for wiring the detector-transmitter:

1. Make sure all source shutters are in the “OFF” position.

2. Make sure all power to the gauge is turned off.

3. Remove the housing access cover. Loosen the screw on the cover retaining bracket and slide the bracket off of the housing cover. Unscrew the housing access cover (two lugs are provided on the top of the cover to aid in the removal of the cover).

4. Remove the cable conduit plugs only from the hole(s) that will be used. As shown in the installation layout drawing, lay one conduit for the DC power input and signal cables, and if applicable, a second conduit for the AC power input and relays. Route the cables into the detector housing and connect the input power and signal wires as shown in the installation wiring diagram.

5. Pull each cable through the correct conduit fitting and into the enclosure. Leave approximately 150 mm (6 inches) for strain relief. Secure the conduit, making sure it is completely sealed.



6. To complete the wiring of the detector-transmitter, follow the procedures described in the “Power Supply Wiring” and the “Board Wiring” sections below.

7. When the wiring is complete, replace the detector housing cover and secure the cover retaining bracket.

Power Supply Wiring

The maximum input power requirement is 6 VA.

Note: To meet the requirements of CSA 1010.1, an external switch or circuit breaker must be installed to allow the power source to be disconnected from the gauge. In addition, protective bonding (grounding) must always be provided, even if a DC power source is used.

DC Power

The Model 9719A/9720A scintillation detector is designed to operate on 24 Vdc (± 20%). When the optional 12-to24 Vdc converter board is installed, the detector can operate on 12 Vdc (± 30%). In either case, the input connector for the DC source voltage wiring is located on the CPU board. Refer to the installation wiring drawing.

Note: To meet the requirements of CSA 1010.1, the input DC terminals shall be

supplied from an SELV (Safety Extra Low Voltage) source.

!

AC Power

If the optional AC power board is installed, the gauge may be operated using either 115 or 230 Vac. The AC supply voltage is set by the 115/230 Vac selector switch on the AC power board.

Warning: Applying 230 Vac with the selector switch in the 115 Vac position will damage the equipment.

The AC selector switch is located behind (below) the connectors on the top edge of the AC power/relay board. To access the selector switch, it is necessary to remove the screws that hold the detector-transmitter unit in the housing and lift the detector-transmitter unit several inches out of the housing.

Caution: For reliable operation and to maintain safety approval, the F1 fuse on the AC power board must only be replaced with an approved fuse. Refer to the Installation Wiring Diagram, Drawing 868580.

If both AC and DC input power are supplied to the detector, the detector will draw power from whichever source provides the higher DC voltage.



Board Wiring

DANGER: Remove all power from the unit before making any connections. Electrocution can result if power is present.

Warning: All wiring must be done by qualified individuals in accordance with National Electric Code (NEC) ANSI/NFPA 70 specifications or the Canadian Electrical Code Part 1. For intrinsically safe systems, refer to ANSI/ISA RP 12.6.

If metal conduit is used, it must be grounded.

After completing the initial wiring preparations, use the following procedure to complete the wiring of the detector-transmitter. For each cable to be connected, refer to the wiring label on the top of the chassis or to the installation wiring diagram. You will need a screwdriver with a 1/8-inch blade to connect the wires to the screw terminal connectors.

1. Make sure all source shutters are in the “OFF” position. 2. Make sure all power to the gauge is turned off. 3. To remove the housing access cover, loosen the screw on the cover retaining

bracket and slide the bracket off of the housing cover. Then, unscrew the housing access cover (two lugs are provided on the top of the cover to aid in removal).

4. Connect the cable to the appropriate connector on the board as follows: − Remove the screw–terminal connector from the on-board connector. If the

connector is tight, brace the board with your hand to remove the screw-terminal connector, but be careful to not touch any circuit components.

− Loosen the terminal screws on the connector. Insert the wires into the connector and make connections as shown in the installation wiring drawing.

− Tighten the terminal screws to secure the wires. Replace the connector on the board when all wires are secured.

5. Install the housing cover. For the explosion-proof enclosure, secure the cover retaining bracket.

Serial Communications

The gauge provides both an RS-232 single-drop and an RS-485 multi-drop serial interface. Screw-terminal connectors for both ports are located on the CPU board.

The RS-485 connector includes the +8 Vdc required to power the Thermo Scientific HHT as well as the +Data and –Data connections. An RJ-11 (phone jack) connector is also provided for the RS-485 port. The HHT can be connected directly to the RJ-11 connector.

Both the RS-232 and RS-485 ports provide independent access to the measurement readings and software functions. Both ports are always active and can be used to display measurements. The Setup Menus, however, can only be accessed by one port at a time.



RS-485 Wiring

To connect the serial (COM) port on a PC to the RS-485 port on the gauge requires an RS-485-to-RS-232 converter (P/N 670045).

• Connect +Data and –Data on the RS-485 connector (located on the CPU board) to the corresponding connections on the RS-485-to-RS-232 converter.

• Connect the RS-485-to-RS-232 converter to the PC using a standard DB-9 serial cable.

Refer to the RS-485 installation wiring drawing (868519) and the Wiring drawing (868578) for details.

Note: Party-line Communications – Initial Setup! To communicate with multiple gauges via an RS-485 party-line, each

unit must be assigned a unique unit identification number so it can be addressed individually. All gauges are assigned unit number 0 (zero) by default.

To assign a unique unit number to each gauge, you must be able to communicate with each gauge individually. You must be able to disconnect each gauge from the party-line in turn and then communicate with the disconnected gauge directly. Alternately, you must remove power from all gauges except one, then assign a unit number to the single powered gauge. Repeat this procedure for the remaining gauges.

Note: If you have trouble using another device on the RS-485 chain, verify that it

is properly terminated for its position on the chain. To terminate a device, connect a 120 Ω resistor between its RS-485 +/– data terminals. Never terminate more than the first and last device in the chain.

RS-232 Wiring

The serial port on a PC (COM1 or COM2) can be connected directly to the RS-232 port on the gauge. This requires five wires - ground, transmit (TX), receive (RX), RTS and CTS. The connections between the gauge RS-232 port (J3 connector) and the PC serial port are summarized in the table below for standard DB-9 and DB-25 PC serial port connectors.

Using Serial Communications

To communicate with the gauge from a PC requires that the PC be running TMTComm for Windows communications software or other terminal emulation software.

The default communication settings for the RS-232 and RS-485 ports of the gauge and for the Thermo Scientific HHT are:

• 7 data bits, • even parity, • 1 stop bit, and • 9600 baud data rate.

Refer to the user guide for additional details about setting up and using serial communications.

HART Communications

The HART communication protocol is supported over the 4-20 mA current output with an optional daughter board. You communicate with the gauge using the standard Fisher Rosemount 275 HART handheld communicator. Refer to the “DensityPRO HART Operation Manual” (717816) for detailed instructions.

Current Output

The current output is programmable between 0 and 20 mA; however, the minimum current output is ~3 mA. The maximum load is 800 ohms. Refer to the installation wiring diagram (Drawing 868578) for details.

The default configuration for the current output is isolated, loop-powered. A jumper is placed across pins 4 and 5 of the 14-pin header J7, located below the RS-484/RS-232 connectors on the CPU.

• Connect the +24 Vdc loop-power input to Pin 7 of connector J10. • Connect the +Iout (current output) signal, Pin 6 of J10, to one side of the user

load. • Connect the other side of the user load to the return of the 24 V loop-power

supply.

Alternately, the current output can be reconfigured as a non-isolated system-powered output by moving the jumper from pins 4 and 5 to pins 3 and 4 on header J7.

To configure the current output as isolated, system-powered, remove all jumpers from J7 and install the optional daughter board, P/N 886595.

Flow Input

There is also provision on the CPU board for a user-provided 4-20 mA Flow (AUX) input (pins 1/2 of connector J10). Refer to the user guide (717784) for details on how to configure the gauge to use the flow input signal.



Relays

Two relays can be provided as an option on the AC power/relay board. (A factory-installed jumper across pins 4 and 5 of header J11 indicates to the gauge that the optional relays are installed. Refer to the installation wiring drawing (and the wiring label on top of the detector-transmitter chassis) for wiring details. Relay contacts are Form C SPDT, isolated 8 A, and 220 Vac.

Contact Closure (Switch) Inputs

The contact closure inputs are dry contact inputs between ground and Switch 1 and ground and Switch 2. The gauge can be configured via software settings to execute a command or other function upon a user-provided contact opening or closing. Refer to the user guide (717784) for instructions for assigning commands to the contact closure inputs.

Chapter 4 Troubleshooting and Maintenance

Thermo Fisher is ready to assist you with any problems you may have with your gauge. Thermo Fisher provides field service, factory service, and replacement parts. Experienced service representatives are available to help. A 24-hour phone number is provided for emergency service calls.

Source Housing

Periodically check the source and remove any debris that may have accumulated in the beam path between the source housing and the outer wall of the process vessel.

Warning: Do not place your hand between the source and the tank. Use a brush or other tool to remove any accumulated debris.

Also check the shutter to make sure it works correctly. For source housings with an exposed shutter lever pivot, you can apply grease to the pivot if necessary to prevent corrosion and jamming.

Note: Do not paint or overcoat the source housing without first masking its identification tag and other labeling. All labels on the source housing must remain visible.

Detector-Transmitter

Danger: Remove all power from the unit before servicing. Electrocution can result if power is present.

In hazardous locations, ensure that power is removed from the detector before removing the housing cover. Be sure that the housing cover has been replaced and that the grounds are properly connected before reapplying power.

Caution: Close the shutter on the source housing before servicing the detector

unit.

AC Power Supply Fuse Caution: For reliable operation and to maintain safety approvals, the F1 fuse on

the AC power board must be replaced with an approved fuse. See the Installation Wiring Diagram (868578) or Appendix B “Parts List.”


Chapter 4 Troubleshooting and Maintenance DensityPRO

Adding or Replacing Boards

The detector-transmitter includes the following boards.

• CPU / DC power board (required) • AC power and/or relays board (optional)

This optional board is available in three configurations. − AC power with no relays − AC power with two relays − Two relays only.

• Isolated, self-powered, 4-20 mA current output - optional piggy-back board that mounts on the CPU board.

Use the following procedure to access the detector-transmitter electronics:

1. Make sure all source shutters are in the “OFF” position. 2. Make sure all power to the gauge is turned off. 3. Remove the housing access cover.

− For the explosion-proof housing, loosen the screw on the cover retaining bracket and slide the bracket off of the housing cover. Then unscrew the housing access cover.

− For the non explosion-proof housing, remove the bolts that attach the housing cover to the enclosure.

4. Disconnect the plug-in screw terminals from the board connector. If the connector is tight, brace the board with your hand (but do not touch the circuit or components) and pull firmly but carefully. Lay the cables and connectors back over the edge of the housing, so they will not be in the way when lifting the unit out of the housing.

5. Remove the screw that secures the unit in the housing. Using a pull and turn motion, lift the unit a few inches out of the housing, so that the electronics boards are exposed.

Factory Wiring

The detector board (positioned horizontally under the top of the electronics chassis) mounts on the photomultiplier tube. A factory-installed cable connects the detector board to the J2 connector on the CPU board.

If the optional AC power board is installed, a factory-installed cable connects the J3 connector on the AC power board to the J9 connector on the CPU board.

If the optional 12-to-24 Vdc converter board is installed (located below the CPU board), a factory-installed cable connects the J2 connector on the 12-to-24 Vdc converter board to the J15 connector on the CPU board.


DensityPRO Chapter 4 Troubleshooting and Maintenance

Current Output Jumper Settings

The default configuration for the current output is isolated, loop-powered. A jumper is placed across pins 4 and 5 of the 14-pin header J7, located below the RS-484/RS-232 connectors on the CPU.

Alternately, the current output can be reconfigured as a non-isolated system-powered output by moving the jumper from pins 4 and 5 to pins 3 and 4 on header J7.

To configure the current output as isolated, system-powered, remove all jumpers from J7 and install the optional daughter board, P/N 886595.

Current Output Problems

If you suspect a problem with the current output, attach an ammeter in series with the current output load and verify the current output at various levels. Use the commands in the “User service & related items” submenu, located under the “Security, service, and diagnostic functions” top-level menu, to hold the current output at specific levels for testing (Refer to Chapter 9 of the user guide for details).

Relay Problems

If you suspect a problem with a relay output, you can attach a continuity tester to the suspected relay output and use the “Test relays” commands to test relay operation. (Refer to Chapter 9 of the user guide for details.)

Troubleshooting & Service

Note: Enable the “service-only items” in the “Special functions” menu before proceeding with this section. Refer to Chapter 9 of the user guide for details on the service-related menus.

If you suspect a detector problem, you can quickly check the detector output using the “Internal value of sensor signal” item in the “Snapshot” menu (Direct Entry Code 112003). This value (count rate in counts per second) should be much larger with the source shutter ON than with the shutter OFF (typically more than 10 times larger).

As a further check, if standardization has been completed, set up the standard configuration and compare the “Internal value of sensor signal” to the “STD value in use” (Direct Entry code 121003) displayed in the “Sensor standardization” submenu of the “Gauge fine tuning” menu. If the gauge was working properly when standardized, the two values should be similar.

If the displayed signal value is not behaving correctly, be sure to consider misalignment of the gauge head, buildup or wear, debris in the beam path, or faulty shutter operation before testing the detector signals.

If you can eliminate these other factors, the cause is probably on the CPU board. Verify that the connectors on the cable connecting the detector board to the CPU board are securely seated on both boards. If the problem remains, call Thermo Fisher for assistance.
