1.1 SHIPPING DAMAGE & SHORTAGES

Before and after the crated machine is unloaded from the truck the crate should be inspected

for any signs of damage. If suspected damage is found it must be noted on the bill of lading

and signed by the driver and the person receiving the shipment. After the machine has been

uncrated inspect it and all other contents of the crate for shipping damage. In the event that

damage has occurred in transit notify the freight carrier and Norfield Industries immedi-

ately. Inspect the complete shipment against the packing slip to make sure all items listed

are accounted for. If any shortages are noticed, the freight carrier and Norfield Industries

should be notified immediately. While any shortages, other than back orders, or freight

damages are the complete responsibility of the freight carrier, Norfield Industries desires to

be notified so that the replacement of lost or damaged parts can be expedited.

1.2 INSTALLATION

The information in this chapter refers to the installation and setup of the Magnum Door and

Jamb Machine. Since the purchase of the machine includes a start-up by a field technician,

the following five items MUST be accomplished before the technician arrives:�

1. Uncrate the machine and inspect for shipping damage or shortages.

2. Position the machine in its permanent location

3. Provide the proper electrical supply (7 wire input) and make connections to machine and

vacuum unit.

4. Provide the proper air supply and make connections.

5. Position and connect the vacuum system.

14

1.3 POSITIONING THE MACHINE

This figure shows the overall dimensions of the Magnum Door and Jamb machine. It is

recommended that you allow 4 feet between the rear of the machine, where the electrical panel

is located, and any wall or structure.

Material flow into and out of the machine should also be considered for optimum

performance. On the infeed end of the machine a minimum 8 feet of loading space is

recommended and on the outfeed end a minimum 4 feet is recommended.

Since the vacuum system can be mounted on either end of the machine placement of the

machine should allow adequate space for the vacuum.

1.4 LOCATIONS OF CONNECTIONS

Figure 1.1 shows the location of the electrical, air and vacuum connection points. Refer to

the other figures noted for complete detail and instructions. If you have any questions

regarding any of these connections contact Norfield’s Service Department for advice at

(530) 891-4214.

1.5 LIFTING & MOVING THE MACHINE

The easiest way to move the machine is by picking it up from above. A steel bracket is

supplied with the machine that can be used as a pick-up point. A chain can be passed

through the bracket and over the forks of a fork lift see figure 1.2. Make sure the chain is

strong enough to support the weight of the machine (approx. 2600 lb.). The bracket is se-

cured to the top of the frame just to the right of the control panel. The machine can also be

lifted from underneath, but it is not recommended due to uneven weight distribution. Also,

be careful not to damage any tubing, wiring, or components mounted to the front or bottom

of the frame.

1.6 ELECTRICAL CONNECTIONS

Before making any electrical connections, insure that the voltage listed on the specification

plate on the electrical box door match those of your building (i.e. 208 volt-3 phase-60 Hz,

230 volt-3 phase-60 Hz, or 460 volt/480 volt-3 phase-60 Hz). Refer to Figure 1.3 for elec-

trical connections to the machine.

Norfield recommends that you have main disconnect switches (one for each input source)

near the machine. These switches are usually wall mounted in a position convenient to the

operator for safety reasons consult your electrician.

Do not lift the machine from any part of this section

FIG 1.2

All electrical connections MUST be made by a qualified electrician.

��

16

1.7 AIR SUPPLY & CONNECTIONS

Clean, dry air is important for the continued performance and low maintenance of air

operated tools and equipment. Foreign materials such as moisture, dirt, grit, and pipe scale, all

generally present in air systems, can cause severe abrasive wear in valves and cylinders.

Before connecting the Magnum to your air supply, insure that you have adequate mainline

filtration and drainage. In addition to adequate filtration, Norfield also highly recommends the

use of an air drying system. If you have any questions regarding your air system, please

contact Norfield Industries or consult with the field technician upon arrival for the start-up, see

figure 1.4. The Magnum requires 2.2 CFM at 90 PSI of clean, dry air for proper operation. If

an air screwdriver and air pre-drill are to be used through the machine's F.R.L. (Filter

Regulator Lubricator) an additional 6.3 CFM will be required. (Total 8.5)

(Continued on page 17)

FIG. 1.3

��

17

(Continued from page 16)

The air supply is connected to the machine at the F.R.L. unit. The supply line should be

1/2 inch. I.D. minimum if the length of the run is 75 feet or less. If the length of the run is

between 100 and 300 feet, 3/4 inch I.D. pipe should be used. Use 1 inch. I.D. pipe for runs

between 300 and 1000 feet.

Never use a supply line less than 1/2 inch inner diameter or any air fitting to connect the air

supply to the machine with less than a 3/8 inch diameter.

��

18

1.8 VACUUM REQUIREMENT

A dust collection unit must be used with this machine. If the machine is connected to an

existing in-plant dust collection system, the system must be capable of moving at least

1900 CFM (Cubic Feet per Minute) at the connection point. Vacuum connection is made at the

Vacuum Collector adapter which can be located on either end of the machine. (See the Pre-

Installation drawing for detailed specifications). Refer to figure 1.5.

If the Norfield Vacuum unit was purchased with this machine, a cord end is provided on

the backside of the machine (230V Phase 3 @ 10A).

Allow adequate space for access to the dust bags and controls of the vacuum system. The

vacuum unit may be placed at either end of the Magnum depending on the layout of your shop.

It is important to have as few bends as possible in the 8” vacuum hose (connecting the

vacuum unit to the machine) as this may affect the efficiency of the vacuum. For optimum

performance lime the vacuum hose length the no more than 10 feet.

2.1 PREFACE

The following is a brief description of the operation procedures of the Magnum. It is

recommended that before processing a door, the operator should make sure that the machine is

properly adjusted for door width, undercut, butt size, lock height, backset, size of lock and

latch bores and size of the faceplate rout. Proper procedures for making these adjustments are

outlined in Section 4.

Refer to figure 2.1 below (for adjustment locations).

FIG 2.1

20

2.2 RUNNING THE MACHINE

1. Turn on SIZER, POWERFEED, and DRILLS motors (In that order). These motors

should remain "ON" unless the machine is to be idle for an extended period of time.

Please refer to figure 2.2 below.

2. Adjust the Top Section for correct door width. On the operator control panel there are

two 3-position selector switches that spring return to the center. They are under the

heading “DOOR WIDTH”. One is labeled FAST in the center and UP and DOWN. The

other is labeled SLOW in the center and UP and DOWN.

There are two methods that can be used to set door width. One is used for automatically

stopping at the standard 2 inch increments and at your pre-set door undercut. The other

method is used to set the machine for any door width between 1-6 and 4-0 by reading the

door width scale, see figure 2.1.

Move the top section in the direction needed to obtain the correct setting by the FAST

switch in either the UP or DOWN position. When you are approximately 1/2 inch to 1/4

inch below the desired door width, rotate the SLOW switch to the UP position and release

it. The top section will go up slow and stop at the next door width .

If you would like to do a special width door, rotate the FAST switch to either the UP or

DOWN position, as necessary, and watch the scale until it is near the width you desire, then

momentarily turn (or bump) the FAST switch until the scale reads the correct door width.

3. Pick up a door and turn it up on edge so that it can be sighted for straightness. If a bow

is noticed, place the door on the infeed bed so that the bow is toward the machine (if

possible). This way the bow will be away from the stop on the jamb when the door is

closed.

4. Adjust the door width with the infeed bed control lever until the undercut reference

marks align, see figure 2.3.

5. Slide the door into the powerfeed system where it will be sized, beveled, and the corners

sanded. To adjust the speed of the powerfeed wheel adjust the knob located in the

operator control panel, see figure 3.4 on page 24. For light cuts and soft woods it can be

set at the fastest speed, but should be reduced for heavier cuts and hard woods for

performance.

6. If the next door to be processed is the same width as the door in the machine, sight it for

straightness and then place it on the infeed bed in the “holding” position (leading end

just under the first roller of the undercut reference assembly).

7. Place the jamb in the desired position on the jamb rack (right or left hand) by pushing

the dado end against the appropriate jamb stop.

8. By this time the first door will be waiting in the drill section. Roll it against door stop at

the same end as the jamb is located. While pressing the door against the main bar and

the door stop, operate foot pedal to clamp door.


FIG 2.3

��

22


9. Start the drill cycle by depressing the foot pedal (located to the right of the clamp

pedal). Release the router carriage by pushing the button on the left side of the router

carriage handle. CAUTION: the motor will automatically start when lowered to about 25 degrees. Lower the router carriage until the locating dog drops over the "top hinge"

index block. The router bit should be between the door and jamb.

10. Clamp the router carriage to the door making sure that the jamb is in contact with the

bottom of the router carriage. If the jamb requires moving up or down to compensate

for different thickness jambs activate the control which is located on the front of the butt

router. It is a two-way toggle switch, pushing it up raises the jamb and pushing it down

lowers the jamb. When the jamb switch is released a brake is applied to hold it in the

desired position.

11. Mortise the door and jamb. When the mortise is complete the router carriage should be

stopped in the forward position over the door. This positions the router carriage so that

when it is lifted it is captured in the appropriate position for lowering the next time. If

you fail to do this, the next time the router carriage is lowered it will bring the bit down

into the jamb.

12. Unclamp the carriage from the door and move the carriage to the next hinge location. It

is not necessary to lift the router carriage to its full up and locked position between

mortises. When the last mortise is completed, raise the carriage up until it locks.

13. Apply the hinges.

14. Unclamp the door and fold the jamb toward you. Roll the door until the lock bore is

over the faceplate template, then activate the stop by pulling the faceplate handle out,

away from the frame. This will activate the locating cone.

15. Push the door against the main bar, turn on the faceplate router and clamp the door by

pushing the button in the faceplate router handle. The router will also plunge into the

door after clamping. mortise the faceplate by following the template.

16. When the faceplate mortise is complete, push the button on the handle to stop the router

and unclamps the door.

17. Remove it from the machine.

18. As the operator walks to their left for another door, grasp the door that is in "holding"

and push it into the powerfeed.

3.1 REGULATOR SETTING

Set the regulator at 90 psi. The black adjustment knob is located beneath the regulator

gauge. Turn the knob clockwise to increase the regulated pressure or counter clockwise to

reduce the pressure, see figure 3.1.

3.2 AIR TOOL LUBRICATOR SETTING

Set the drop type lubricator so that two to four drops of oil is mixed with the air supply

every minute. Adjustment is accomplished with the adjustment knob which is located next

to the oil fill port. Turning the knob counter clockwise increases the oil drip rate. Observe

the drip rate through the sight bulb on top of the lubricator.

��

Over tightening the adjustment knob will damage the lubricator.

FIG 3.1

24

3.3 ADJUSTMENT FOR DOOR WIDTH

The top section can be raised or lowered to adjust the machine for any door width between

1-6 and 4-0. There are two methods for establishing door width, 1) index at 2" nominal

widths, or, 2), stop the width adjustment at any increment using the width scale. The

controls for making this adjustment, the “DOOR WIDTH” switches are located on the

main control panel at the front of the machine. CAUTION: There should be no doors

in the machine when this adjustment is made.

3.4 ADJUSTING FOR NOMINAL WIDTH DOORS

To raise or lower the top section rotate the FAST switch to either the UP or DOWN

position, as necessary, and watch the scale until you are approximately 1/4” below the width

setting you want, then rotate the SLOW switch to the UP position and release it. The top

section will go up slow and stop at the next door width.

3.5 ADJUSTING FOR ODD WIDTH DOORS

Rotate the FAST switch to either the UP or DOWN position, as necessary, and watch the

scale until it is near the width you desire, then momentarily turn (or bump) the FAST switch

until the scale reads the correct door width.

3.6 UNDERCUT

The Magnum is designed to size and bevel doors to an exact width. Since many doors come

from the manufacturer under nominal width, most pre-hung door manufacturers size all

doors 1/16" to 3/16" under nominal size. A 1/8" undercut is most common. A 2'-0" door

undercut 1/8" would be 23-7/8" from the hinge edge to the long point of the bevel.

25


The Magnum is adjustable for up to 3/8" undercut on a nominal sized door. For removing

more than 3/16”, or in some harder wood stile doors, the powerfeed feed rate must be

reduced. CAUTION: Never attempt to make large cuts at a fast powerfeed settings.

If you are sizing doors that are considerably oversized and/or you are attempting a large

undercut, the cutterhead must be SHARP and the cutterhead V-belt must be TIGHT. It is

recommended that you use the slower powerfeed speed settings when large undercuts are

made. The machine is factory set for a specific undercut of 1/8". The undercut scale,

located on the side of the left width carriage, displays the undercut the machine is set for.

Next to the scale is the undercut adjusting knob.

When the undercut pointer aligns with the center "O" mark on the scale, the machine is set

to bevel doors at nominal width (no undercut). To change the undercut to 1/8", loosen the

locking knob and adjust the undercut assembly watching the pointer until it aligns with

1/8". Tighten the locking knob and check the alignment of the pointer and the 1/8" division

below the "0" mark again.

3.7 BACKSET ADJUSTMENT

FIG 3.3

��

��

26

The distance from the long point of the beveled edge to the center of the lock bore is

referred to as backset. The machine is quickly and easily adjustable from 2-3/8” backset to

5”, or any measurement in between. The backset adjustment (located on top of the frame

above the Lock Drill) is factory set so it will bottom out at 2-3/8” when turning the

adjusting crank counterclockwise and stop at 5” when turning the crank clockwise. The

backset can be set at any intermediate position and the lock drill's position will be

maintained until the backset is changed.

When doing any backset greater than 2-3/4” the latch drill stroke will have to be increased

to allow it enough travel to reach the lock bore hole, this is simply accomplished by the

LATCH STROKE selector switch mounted on the operator control panel.

As a rule, when the backset is changed to any setting other than 3”, the particle board drill

back-up block will also have to be changed to prevent tear-out of the lock bore.

3.8 LOCK HEIGHT

Lock height is defined as the distance from the center of the lock bore to the top of the door.

On the Magnum, lock height is determined by a door stop that always references the top of

the door to the Lock Drill and Latch Drill. The standard stop system is adjustable for all

standard lock heights up to 8'-0" doors. In order to set the lock height follow the

instructions below.

1. Set the door and jamb stop assembly on the index bar, but do not tighten the locking

screws, refer to figure. 3.6.

2. Mark a door with a line at the desired lock height from the top of the door, i.e. 44” from

the top for a 6-8 door.

3. Place the door in the door clamps with the top towards the stop you want to set.


FIG 3.5

��

��

28


4. Position the door so that you can see the line centered in the back-up block lock bore

hole, then clamp the door. Norfield recommends that you draw a line on the back up

block in the center bottom of the hole to increase accuracy of this step.

5. Position the door stop assembly against the top of the door, without moving the stop and

tighten the locking screws.

6. With the drill motors OFF and the door clamped, step on the cycle start foot pedal, when

the lock drill bit contacts the door unclamp the door, this will return and reset the drill

cycle. Remove the door from the machine and measure from the top of the door to the

drill mark left on the door by the bit.

7. Adjust the door stop screw until you have achieved 44" (or the dimension you desire).

3.9 HEADER CLEARANCE


FIG 3.6

��

��

29


Header clearance is the gap between the top of the door and the head jamb, usually 1/16" to

1/8". Normally this dimension will not require changing. However, if an adjustment is

necessary check the lock height first and adjust the jamb stop only if the lock height is

correct. Adjusting the door stop to change header clearance will result in an incorrect lock

height.

3.10 CHANGING THE LOCK BIT

The lock drill bit can be changed from the front of the machine. Activate the front panel

switch labeled “BIT CHANGE”. Open the drill cover.

The lock drill chuck is located on the lock drill motor shaft. There are two set screws in the

forward half of this chuck which secure the lock drill bit in place. Loosen these two set

screws to remove the drill bit.


ENGAGE THE EMERGENCY STOP OR THE BIT CHANGE SWITCH

PRIOR TO ATTEMPTING ANY BIT CHANGES BE SURE ALL

TOOLS HAVE COME TO COMPLETE STOP.

FIG 3.7

��

��

30


The replacement bit must have a flat ground on the shank otherwise it will not fit into the

chuck. There is a pin inside the chuck to prevent the bit from turning in the chuck in the

event the set screws are not properly tightened. When inserting a bit, rotate it until the flat

aligns with the pin and push the bit into the chuck until it bottoms out in the chuck. This

will permit the door to pass without striking the drill tip and will allow proper chip

clearance between the drill and the chip deflector plate just inside the main frame. Tighten

the set screws securely.

3.11 CHANGING THE LATCH DRILL BIT

Supplied standard for the latch drill of your machine is a "single fluted flat type" drill bit.

To remove this bit use a adjustable wrench secured across its flats to keep it from

turning while you use a 1-1/4” wrench on the flats on the latch drill chuck to break

loose the tightened threads. The bit can then be unscrewed by hand. As an option a

"double fluted twist type” drill bit is available. To remove it, it is necessary to insert a

punch in the hole through the bit to keep it from turning, and then, just as with the "flat"

type, use a 1-1/4” wrench on the drill chuck shaft to break loose the tightened threads.

When re-installing a bit use the appropriate method to snug the bit after hand tightening.

3.12 CHANGING OF LOCK BORE BACKUP BLOCK

Each time the bit size or backset is changed the lock bore backup block must also be

changed. The same block may be used not for 2-3/8” and 5” backset with each different

bore size, but a separate block must be used when boring at 2-3/4” backset because the

bores will overlap. NOTE: Backup blocks must be exactly 3/4” thick or latch drill centering

will be changed.

Backup blocks can be purchased from Norfield Tools & Supplies @ 1-800-824-6242.

3.13 SANDER ADJUSTMENT

The sander is designed to relieve the sharp corners on the lock edge left by the sizer/

cutterhead. The adjustment for raising the sanding wheels is located just above the sander

on the top side of the main frame. Turn the adjustment knob 1/4 turn each time there is an

indication that the corners are too sharp.


Do not attempt to use sanding wheels after they are worn smaller

than 4" in diameter. Doing so will cause the sander wheels to lift

the door and an uneven edge will result.

��

��

31

3.14 CHANGING BUTT SPACING

From time to time you may need to change your butt spacing on an existing index bar,

or set up a new index bar. To accomplish this, the following procedure is suggested:

1. If changing an existing index bar, use a metal scribe, mark the location of the index

blocks when they are set for your standard spacing so you can accurately and quickly

return them to standard.

2. Place the "non-standard" or “set-up” door in the machine, roll it to the proper door stop

and clamp it.

3. Starting at the top of the door measure down the door edge and make a mark where the

top of each butt is to be located.

4. Loosen the set screws in the router index blocks.


FIG 3.8

��

��

32


5. Lower router carriage until the locating dog on the router carriage is over the index

block nearest the top of the door, and the router carriage is resting on the door.

6. Slide router carriage back and forth until the applicable "butt reference line" on the

door clamp bar is properly aligned with the mark on the door nearest the top of the door,

see figure 3.8.

7. Move the door while holding the stop to tighten set screws in router index

8. block. Clamp router carriage to door and check to make sure that the lines are still

aligned. Repeat process for other butts.

9. If frequent changes in butt spacing are made, we recommend the purchase of a second

index bar with six index blocks and two door stops. The entire index bar can be quickly

changed by releasing the locking clamp mechanism.

3.15 CHANGING SIZE OF MORTISE

Referring to figure 3.9, when all three sets of the pendulum stops are in the path of stop

screws the mortise will be 3-1/2” wide. As stops are rotated out of the path of the stop

screws the mortise will increase to 4”, 4-1/2” and 5” wide. The distance of cut into the door

and jamb is controlled by the stop turret, which can be rotated to change from 3-1/2” to 4-”

butts. The turret stop screws will fine tune the depth of cut for each setting.

The turret stop shown in figure 3.9 is routable for use with 3.5” or 4.0” butts and is so

marked. If 4-1/2” or 5” butts are called out only occasionally, one set of stop screws on the

turret stop can be readjusted, or if you have frequent occasion where 4-1/2” or 5” butts are

called out, you will find it advantageous to purchase a second turret stop for this purpose.

Like the stop system in Fig. 4-10 used for flat jambs, the turret stops can be easily

interchanged without disturbing their settings.

Different butts from different manufacturers vary slightly in width. This can be

compensated for by adjusting stop screws. Also, if you sharpen your router bits the

diameter of the bits will change and you will need to compensate for this by adjusting the

stop screws.

The use of the turret stop system is designed to "work" to the stop on the jamb and to the

outside edge of the door, represented by the clamp plate that secures the router carriage to

the door.

The actual distance routed into the door will vary as the thickness of the door varies, and the

actual distance routed into the jamb will vary as the reveal varies.

This system has three basic advantages: It automatically compensates for different

thickness doors and for jambs with varying reveals, it automatically compensates for


��

��

33


crooked jambs and it allows the operator to always maintain an exact clearance between the

door and the stop on the jamb when the door is closed.

3.16 ROUTING FLAT JAMBS

When mortising flat jambs (jambs with no stop) the stop system shown in figure 3.10 is

used to control the movement of the router in the transverse direction (across the hinge pin).

The “Stop Dog” is rotated to the down position, this tab will be positioned between the door

and jamb. By adjusting the stop screws the distance of mortise into the door and into the (Continued on page 34)

FIG 3.9

��

��

34


jamb can be precisely controlled. This stop system is generally used for 3-1/2” butts only.

If you have need to mortise for 4” butts on jambs with no stops, it is recommended you

purchase an extra Flat Jamb Stop Assembly and set it for 4” butts. The two assemblies are

quickly and easily interchangeable and the individual settings are not disturbed by

removing and replacing them on the router carriage.

3.17 CHANGING THE MORTISE DEPTH

If the butts you use vary in thickness this can be compensated for by adjusting the depth of

the router. Move the adjustable scale clockwise so that 0 on the scale is located exactly

above the pointer on the base. Open the locking lever and turn the depth adjustment ring


FIG 3.10

Locking Clamp

Adjustment Ring

FIG 3.11

��

��

35


until the bit is at the desired depth. Turning the ring clockwise raises the cutting head while

turning it counterclockwise lowers the cutting head. Turn the depth adjustment ring along

with the adjustable scale to the desired depth. Note that each mark on the adjustable scale

represents a depth change of 1/64" or .015" (.4mm). Close the locking lever.

This section describes special adjustments that may become necessary during the life of this

machine. This includes those adjustments that will be necessary to make after certain parts

are replaced.

4.1 INFEED BED

The infeed bed must be parallel with the outfeed bed. The combination of the four

components - infeed bed, cutterhead, outfeed bed, and outfeed rollers add up to a bed-type

planner (or Jointer). If the infeed bed is parallel to the outfeed bed, but 1/8” under the

outfeed bed, then you would remove 1/8" from the door at the high point of the bevel.

The Outfeed bed is not adjustable. The Infeed bed, Cutterhead &

Outfeed rollers are all adjusted in relation to the Outfeed bed.

FIG 4.1

38


Should you experience problems in cutting a straight edge on your doors we urge you to

proceed with caution in your efforts to correct the problem. Ninety-nine percent of all

problems in this area arise from the cutterhead rather than the Infeed Bed, outfeed bed or

rollers. If you have attempted to solve your problem and you are completely satisfied that

the problem is not with the cutterhead, then we suggest you call the factory before

attempting to adjust the infeed bed.

4.2 ADJUSTMENT OF INFEED BED CLUTCH

The clutch is located on the infeed bed pivot shaft inside the frame. The purpose of this

clutch is to provide the proper amount of friction for the infeed bed handle so that it can be

adjusted and will stay where you leave it. As the friction discs wear after long periods of

service, a lessening of the friction may be noticed. When this occurs, a slight adjustment of

the clutch is necessary.

1. Back off all tension screws at least three turns.

2. Loosen the adjusting nut set screw at least six turns.

3. Reset the adjusting nut. Turn clockwise for more torque or counterclockwise for less.

One valley at a time.

4. Tighten the adjusting nut set screw in nearest

spline notch. Do not tighten set screw on

threads of hub.

5. Tighten the tension screws alternately and

evenly until the heads bottom. Do not use

washers under heads of these screws.

6. Check the friction on the infeed bed handle to

see if it is too tight or to loose. If necessary, re-

adjust until the proper tension is provided.

4.3 OUTFEED ROLLER

To the right of the outfeed bed, facing the machine, there are four rollers called outfeed

rollers. They are positioned at the factory and are referenced to the outfeed bed. It is not

likely they will ever get out of adjustment. Adjusting these rollers in the field by other than

factory trained service people is not recommended. If there is a problem in obtaining a

straight edge on the door the problem is most likely the cutterhead or possibly the Infeed

Bed. For instance, if an undersized cutterhead is placed on the machine or if the Infeed Bed

is tilted forward, the door will “bump” the outfeed bed and cause a "nick" in the door edge

11” from the front end of the door. Investigate the cutterhead and/or infeed bed and make

adjustments.


FIG 4.2

��

��

39


After years of use, the outfeed rollers will wear to the point that they will need to be

replaced. Their useful life can be extended by keeping them and the shafts they turn on,

clean at all times and by reversing them on the shafts periodically. This is practical since

only the high point of the bevel actually rolls on the rollers.

4.4 CUTTERHEAD

The “effective cutting height” of the cutterhead is a term used to describe the location of the

long point of the bevel on the door as it is being sized. The long point of the bevel is always

towards the machine and the door slides against a permanent reference, or fence. It doesn’t

matter how thick the door is, the effective cutting height of the cutterhead remains constant,

assuming the diameter of the cutterhead and the “set” of the blades remain constant.

The relationship between the effective cutting height and the outfeed bed is extremely

critical. THEY MUST BE THE SAME HEIGHT, or an uneven edge will result. If you

change the cutterhead and the new cutterhead is smaller in diameter or if the blades are set

differently, and a problem with the sized edge develops, you should determine what the

problem is with the cutterhead and resolve it before making adjustments. Adjust the height

of the cutterhead mandrel to the outfeed bed only as a last resort, first determine what has

changed to create the problem.

4.5 CUTTERHEAD HEIGHT

Should the need arise to remove the cutterhead mandrel assembly from the machine to

replace the bearings, or to install a new mandrel assembly. The following procedure is

recommended, refer to figure 4-3.

1. Turn off all electrical power and lock and tag-out the machine

2. Remove cutterhead shroud, pulley and belt.

3. Loosen lower set screw (inside machine just under mandrel) one turn.

4. Remove 4 bolts that secure mandrel to frame.

5. Install a new mandrel (or mandrel with new bearings).

6. Moderately tighten 4 bolt that secure mandrel to frame.

7. Tighten bottom set screw. (Continued on page 40)

Before beginning any service repairs, general maintenance, or adjustments you MUST

follow proper Lockout Tag-Out procedures. OSHA regulation 1910.147 establishes a

minimal lockout tag-out procedure to assist employers in development of their own

procedures.

��

��

40


8. Tighten 4 bolts securely.

9. Replace cutterhead.

10. Place a beveled, straight-edge door on the outfeed bed. Pressing the door firmly against

the machine, roll it to your left until the left end of the door is over the cutterhead. Using

the pressure of the second powerfeed wheel to hold the door in place, rotate the

cutterhead backwards. The cutter knives should touch the door, but still turn freely. If

this condition does not exist, raise or lower cutterhead until you achieve this condition.

4.6 CUTTERHEAD REPLACEMENT

The condition of the cutterhead should be inspected daily. The cutterhead knives are

carbide which means that anything metallic, either in the door or stuck to it, will chip or

actually break one or more knives. It is good practice never to put a door “edge down” on

the floor as foreign particles (rocks, dirt, metal particles, screws, etc.) may be picked up by

the edge of the door. A chip in the cutterhead will show up on the door as a ridge the entire

length of the beveled edge.

To replace the cutterhead:

1. Turn off all electrical power and lock and tag-out the machine .

2. Open the front cover to expose cutterhead and powerfeed wheels.

3. Remove locking pin from first powerfeed plate. (Continued on page 41)

FIG 4.3

��

��

41


4. Remove the cap on cutterhead vacuum shroud.

5. Using two wrenches, hold the mandrel shaft and loosen the cutterhead nut

6. (LH threads on mandrel shaft).

7. Remove dull cutterhead and replace or replace disposable insert blades.

8. Reinstall nut, vacuum cap, powerfeed plate locking pin. and close cover.

4.7 CUTTERHEAD MOTOR DRIVE BELT

Your cutterhead motor is equipped with a motor base/belt tension device. Loosen the lock

nuts securing the motor base to the rails (not screws that secure rails to frame) and turn the

adjusting bolts clockwise to force the motor away from the cutterhead mandrel. Be careful

to keep the motor drive pulley aligned with the mandrel pulley. After taking up the slack in

the belt, tighten the lock nuts. Check for 1/4” deflection of the belt at center between the

motor pulley and mandrel pulley.

4.8 SANDER WHEELS REPLACEMENT

1. Turn off all electrical power and lock and tag-out the machine.

2. Open the powerfeed cover and the locking pin from the second powerfeed plate.

3. Use a punch to keep shaft from rotating while loosening the locking nut.

4. Note carefully the side of the sander wheel which has the abrasive and replace the new

wheels one at a time. The two shafts turn toward each other so the wheel goes on the

first shaft, the closer of the two shafts, with the abrasive at the top of the wheel toward

the door. The second sander wheel goes on the rear shaft also with the abrasive toward

the door Be careful not to loose the bushings.

5. Each wheel requires a bushing and a pair of 5/8” flat washers on either side of its hub.

6. Reinstall bushings, wheels, and nuts (NOTE: left-hand treads on the long shaft).


Use of a dull Cutterhead will shorten the life of the mandrel

bearings, drive belt & the motor.

��

��

42


7. Lower the sander with the knob on top of the machine until the wheel is just touching

the opening in the frame.

8. Reinstall locking pin in powerfeed plate and close guard.

4.9 SANDER DRIVE BELT

The sander wheels present no great load so the sander double V-belt need not be tight. In

fact, if the belt is overly tight, the belt life is very short. Loosen the 3/8”-16 hex bolt and

raise or lower the idler pulley mounting block until there is about 1” deflection of the belt

on the nearly vertical section of the belt nearest the infeed end of the machine. Be careful

not to miss-align the idler pulley as it is adjusted.

4.10 REPLACEMENT OF POWERFEED WHEELS

Should the need arise to replace one or both powerfeed motors, scribe a line around the base

of the motor to be replaced so the new motor can be mounted in the exact position of the

original. This is important as the motors are “canted” at the factory so as to create enough

downward pressure on the door to overcome the lifting action of the cutterhead and sanding

wheels. Without this "cant" there is no assurance that the edge of the door will be straight.

On the other hand, if the “cant” is too great, the door will be pulled down on the cutter

assembly so much that the door will hit the outfeed bed, causing a poor edge on the door.

4.11 CENTERING OF THE LATCH DRILL IN THE DOOR

If you process any doors with a 5” backset, then this adjustment, if required, should be

made with the backset at 5”. Press door against Main Bar, roll it to door stop and clamp in

the usual manner. Bore and drill for the lock and latch bolt. Measure the amount the latch

bolt is off center in the door edge and the amount it is off center where it enters the lock

bore. If the latch hole is off center more where it enters the door edge than where it enters

the lock bore. The problem can usually be corrected by following these suggestions:

1. Turn off all electrical power to the machine and lock and tag-out.

2. Note the amount the latch hole is off center from the last door to be machined.

3. Measure and record the distance from the center of the latch drill to the main frame. Add

or subtract step #2 measurement from this distance.


Do not over adjust the sanding wheels, it will cause excessive wear, a

light touch on the door edge is all that is required.

��

��

43


4. Loosen the eight hex bolts, four on each side of the latch drill assembly that secure the

assembly to the frame mounting brackets.

5. Move the entire latch drill assembly toward you or away from you to achieve the

dimension you arrived at in step 3 above. The latch drill assembly can be moved in and

out, and the parallel to the frame can be changed by moving the top or bottom unequally

to correct the angle drilled into the door.

6. Tighten the hex bolts.

4.12 ALIGNING LOCK AND LATCH DRILLS��

Under normal operating conditions the lock and latch drills will remain properly aligned.

However, should the machine (or in particular the lock drill) sustain a severe jar, the lock

drill can become misalign. Also, should you remove the lock drill motor for repair or

replacement the new or repaired motor will need to be realigned with the latch drill.

Following is a suggested procedure:

1. Clamp door.

2. Cycle the lock and latch drills to bore a set of test holes in a door.

3. Remove the door and extend lines from the lock hole edge to the door edge with a

square.

4. Measure from the lines drawn in step 3 to the latch hole. Measurement “A” should equal

measurement “B”.


FIG. 4.4

��

��

44


5. If the bores are not aligned the latch bore can be adjusted by loosening the bolts that

secure the assembly to the frame and moving slightly to the left or right as needed. Be

sure to keep the motor at a right angle to the door. Then check the lock height from the

door stop and adjust if necessary.


FIG 4.5

4.13 ADJUSTMENT OF DRILL SENSORS - LOCK

Under normal operating conditions the lock drill will remain properly adjusted for depth of

cut. However, should the need arise for adjustment, the sensors on the cylinder will need to

be moved. As shown in figure 4.6 below there are three sensors. The home sensor indicates

that the lock drill has returned to its resting position. If it is not triggered the drill cycle will

not start. The door pull sensor is used when the operator wants a pocket ,not a full bore,

through the door. This may need adjustment if the depth of cut needs to be changed. The

lock bore limit sensor may need adjustment if the cutter is not cutting completely through

the door. To adjust these sensors all that is needed is a flat blade screwdriver. First loosen

the machine screw then move the sensor along the cylinder as needed. Tighten down the

screw when done.


FIG 4.6

��

��

46


4.14 ADJUSTMENT OF DRILL SENSORS - LATCH

Under normal operating conditions the latch drill will remain properly adjusted for depth of

cut. However, should the need arise for adjustment, the sensors on the cylinder will need to

be moved as was the case with the lock drill. As shown in figure 4.7 below there are three

sensors. The home sensor indicates that the latch drill has returned to its resting position. If

it is not triggered the drill cycle will not start. The short stroke sensor is used for certain

backsets. This may need adjustment if the depth of cut needs to be changed. The lock bore

limit sensor may need adjustment if the cutter is not cutting completely through the lock

bore. To adjust these sensors all that is needed is a flat blade screwdriver. First loosen the

machine screw then move the sensor along the cylinder as needed. Tighten down the screw

when done.�

FIG 4.7

4.15 LATCH PLATE MORTISE CENTERING

Centering the latch plate mortise in the edge of the door is accomplished by adjusting the

nuts securing the template holder posts to the frame, see figure 4.8.

Be sure to retain the 1/16” gap between the template holder and the door when adjusting the

mortise centering.

To center the latch mortise on the latch bore, the air cylinder that activates the alignment

cone can be adjusted on its mounting bracket. Loosening the cylinder mounting bolts and

shift the cylinder side to side (not at an angle) until the mortise is centered on the latch bore.

Tighten the mounting bolts securely�

4.16 LATCH PLATE DEPTH


FIG 4.8

��

��

48


To establish the vertical travel of the latch mortising assembly, lift the latch routing lever by

activating the button in the handle (no door in the machine and with the motor switch off). Check to see that the base of the template guide on the control weldment does not touch the

bottom surface of the template holder. If it does touch the template, the control weldment

must be lowered slightly by loosening the shaft collars. When at rest, the template guide

should now be touching at least 1/16” of the bottom of the template. After the template

holder is set at the correct height and the vertical travel is correct, the depth of the actual

mortise may be adjusted. To mortise deeper, loosen the micrometer and adjust the router up

into the casting the amount needed and tighten the micrometer. If the mortise is too deep,

use same procedure except lower the router.


There should be 1/16” clearance between the top of the template

holder and the long point of the beveled edge of the door.

Always Disconnect the router motor electrically before removing it from

the casting.

��

��

FIG. 4.9

49


4.17 MAIN BAR

Calibration Check

The Main Bar is the rectangular long tube assembly that is affixed to the width carriage

assemblies. It must be parallel to the outfeed rollers. To ascertain this, select a door that has

just been sized and beveled, measure it to make sure it has no taper, check the scale on the

machine to see if it reads the exact width of the door you just measured, and then place it on

the outfeed rollers. Now, at each end of the door, measure from the hinge edge down to the

main bar. This measurement should be 2-1/2” at each location.

If the dimension of the door to the main bar are equal but are not 2-1/2”, the following

procedure should be used:

1. Calculate the difference of error from 2-1/2” , as an example if the actual measurement

is 2-7/16” the error would be 1/16”.

2. Move the door width scale pointer by the amount of the error, up for a measurement less

than 2-1/2”, and down for a greater dimension. until you achieve the required 2-1/2”.

After moving the scale you will need to re-set the door width using the elevator buttons.

3. Re-calibrate the pointer on the undercut scale by loosening the pointer and moving it to

the correct reading. The reading of the scale should be the same as the undercut of the

door sized.

4. The indicator lines on the undercut reference roller assembly may also need calibration,

The red lines should align when the door is 2-1/2” above the main bar.

If the dimension on the undercut scale is different than the measured door width, the

following procedure should be used:

1. Re-calibrate the undercut scale by moving the pointer until it reads correctly, move just

the pointer without adjusting the assembly up or down.

2. Re-calibrate the undercut reference roller indicator until you have the 2-1/2” dimension

and the proper undercut, this may require repeating steps one and two several times.

�� Set the undercut scale to read exactly what the door width is by moving the pointer.�

If the dimensions are not equal from the hinge edge of the door to the main bar, adjust the width carriage on the outfeed end (right side) by moving the torque tube gear up or

down as required, an adjustment screw is provided at that location.

��

��

50

4.18 JAMB RACK ADJUSTMENT

Angular Adjustment

The jamb supports should be at an angle of 90 degrees from the face of the door. This can

be checked with a framing square. To establish the correct angular orientation between the

jamb and the door the jamb rack may be rotated. By loosening the jamb nut and turning the

adjustment link (using the flats) see in figure 4.10 below. By shortening the link the jamb is

tilted towards the door and by lengthening the link the jamb is tilted away from the door. Be

sure to check and adjust both ends of the jamb rack.

Parallel Adjustment

The jamb should be parallel to the top of the door for correct hinge pattern routing. This can

be checked by raising the jamb lift to the correct height and checking the relationship of the

door and jamb with a framing square set flat on the jamb and the top of the door. If

adjustment is necessary, this can be accomplished by loosening the jamb nut, removing the

clevis pin, and then rotating the clevis to either extend or retract the length between the

cylinder and the link, see figure 4.11. This in turn will raise or lower the jamb rack and

jamb to obtain parallelism. A combination of adjustment on both sides may be necessary.

4.19 LEVELING THE ROUTER CARRIAGE

In order that the router mortises to the same depth both in the door and in the jamb, it is

necessary that the router carriage be level both before and after clamping it to the door.

Before attempting to level the router carriage, though, you must ascertain that two

conditions exist:

→ The hinge edge of the door is 2-1/2” above and parallel to the main bar, see figure 4.12.

If one end of the main bar is low and the other end is high, the mortise will be deeper in

the door at one end and deeper in the jamb at the other end.

→ A gap of 1/32” between the door clamp bar and the door exits when the carriage is

resting unclamped on the door edge and the door is pressed against the main bar. If the

gap is less than 1/32”, the clamp bar will strike the edge of the door as the carriage is

being lowered. If it is greater than 1/32”, the action of the clamp cylinder will pull the

plate and tram rollers forward causing the pivot point to lower and a deeper mortise in

the jamb will result. If the gap is not 1/32”, loosen the four screws that secure the

adjusting bolts to the plate and adjust the carriage by turning the adjusting bolts equally

to attain a 1/32" gap. Retighten the screws. If the jamb reference bars do not rest flat on

the door edge with the carriage down, the following procedure will correct this:

After checking the above conditions use the following procedure to correctly level the

router carriage:

1. Make sure that your door edge is square.

2. Loosen the three tram rollers and raise or lower plate until the jamb reference bars are

resting flat on the door edge.

3. Tighten the top center roller.


FIG. 4.12

��

��

52


4. Position and tighten the lower rollers, leaving a 1/32” gap between each of them and the

bottom of the tram rail. This will permit the carriage to "rock", thus conforming to the

door edge should the edge be slightly bowed.

5. Adjust the felt wipers to effectively wipe the top surface of the tram rail�

4.20 CHANGING ROUTER BIT RADIUS

If you change bit radius, i.e. 5/8” radius to 1/4” radius, you must also change the butt router

travel stops.

1. WIDTH - Two sets of mounting holes are provided for the width stop mount. Simply

move the block to the proper position by removing the two mounting bolts, see figure

2. TRANSVERSE - Across the hinge pin travel, must also be changed by adjusting the

turret stop screws, see figure 4.13. It may be necessary to change the length of the

adjusting bolts or screws. If you change radii often, you will find it advantageous to

purchase an extra stop turret and/or Flat Jamb Stop Assembly so quick changes can be

make without disturbing settings.

4.21 BUTT ROUTER CARRIAGE BUSHINGS

The useful life of the bushings in your router carriage will depend upon how well the rods

they slide on are kept clean. If any type of lubricant is used on the rods, the bushings will be

short-lived.

When the bushings do wear to the point where the carriage no longer makes an acceptable

mortise, you may (1) replace the bushings yourself, (2) have them replaced at a machine

shop, or (3) purchase a rebuilt router carriage from the factory. If you choose to install new

bushings into the carriage yourself, you will need a press and two line reamers, one 1/2”

and one 5/8”. To replace, press or drive the old bushing out FROM THE OPPOSITE END

and�press the new bushings in, taking care not to damage them. Once inserted, line ream

each pair of bushings to fit the matching slide rod. Since most door shops do not normally

have presses and line reamers, we would suggest you contact the factory for a replacement

carriage, as the cost will, as a rule, not exceed the cost of taking your router carriage to a

machine shop. Plus you save the down time.

�

Contact Norfield’s Service Department for advice if you plan on changing the

bushings yourself.

4.22 CHANGING THE BUTT ROUTER FROM 0 TO 3 ½ DEGREE.

This will allow the Magnum to machine the hinge mortises flush with the beveled edge of

the door. The jamb can be held and machined at the same angle. Simply install the 6 jamb

riser wedges, item number 0001-741 which is included with standard machine. The wedges

slip over the jamb risers on the Magnum jamb rack and are held in place by a thumbscrew

on the side. The thin end of the wedge should point toward the operator.

1. Unplug the Butt Router motor, whenever you work on or make adjustments to the butt

router assembly the router must be unplugged.

2. Lower the butt router assembly.

3. Press the butt router latch button and raise the butt router assembly slightly, to release

the latch pin. Maintain pressure on the latch button while you lower the butt router

assembly.

4. Unlock the pivot pins.

5. Located on each side of the butt router assembly are two pivot lock pins (see figure

4.14). Pull the pin out and rotate it 90°. With both pivot lock pins unlocked push down

on the butt router handle. This will cause the pivot blocks to move up in their slots.

Hold the handle down and rotate the pivot lock pins 90° and allow the pins to lock the

pivot blocks in the up position.

6. To return the router to its normal position, simply reverse the procedure.

5.1 GENERAL MAINTENANCE

Door machines work in an environment of endless sawdust. Sawdust is not only very

abrasive when allowed to penetrate motors, bearings, etc., but it also contains pitch. Pitch

clings to sliding surfaces and eventually coats the bearings. Mechanisms become “sticky”

and, if not cleaned, soon become inoperable. To combat the effects of sawdust on your

machine the following recommendations are made:

1. Using an air hose blow all motors and routers off 2-3 times daily.

2. Clean slide rods on router carriage and latch drill daily with a non-oil based solvent

(Electrical/Electronic Grade Contact Cleaner), and wipe rods completely dry with clean

dry cloth. DO NOT LUBRICATE! Any type of lubrication on these slide rods will

merely collect more sawdust. Clean and wipe dry the slide rods on the lock and latch

drills weekly.

3. Clean gears and gear racks on elevator mechanism daily. A good stiff brush is best, but

an air hose is better than nothing. DO NOT LUBRICATE! Wipe vertical posts on

elevator clean daily.

4. Once a month remove door edge rollers and clean the roller I.D. and shaft O.D. with a

non-oil based solvent, electrical/electronic contact cleaner. Wipe dry, DO NOT

LUBRICATE!

5. Inspect and clean weekly the two cam guides and rollers on the jamb rack These

components are located on the backside of the jamb rack on opposite ends. First blow

the cavities clean, then take a brush and clean any pitch left on the rollers and guides.

5.2 CUTTERHEAD

When the blades of the Cutterhead become dull or damaged it will be necessary to replace

them. Please keep the following three items in mind.

1) Each blade is reversible and can be used twice.

2) Only use the correct inserts for this cutterhead for proper operation, The replacement

blades are available from Norfield Tools and Supplies.

3) The head turns in excess of 7000 RPM and any imbalance will result in severely

shortening the life of the bearings in the cutterhead mandrel, in addition to giving a poor

finish to the door edge.


56


Most local grinding services are not equipped to provide the proper sizing and balancing.

Therefore, we urge owners not to send their cutterheads or knives for sharpening. Use only

the correct replacement knives.

5.3 ROUTER BITS

Router bits will need to be sharp to provide a clean, well formed mortise. Check router bits

once daily and replace if the router bit looks burnt or dull.

5.4 DRILLS

Drill bits need to be kept sharp at all times Failure to do so will result in the use of

additional electrical current and shorten motor and bearing life. Here again, we believe we

can do a superior job in sharpening your drill bits and we solicit this work from you.

5.5 FILTERS

The air filters on your machine are designed to further clean air that is not heavily laden

with moisture or impurities. If excessive water or pipe scale, etc., is present in the air to the

filters, the filters will clog up and pass through the excess water, etc. For this reason if you

do not have an in-plant air cleaning system, we suggest you contact the Norfield Service

Department or your local air system supplier for assistance in correcting this problem.

Water present in air cylinders and valves will severely shorten their life by up to 90%!

Check the air filters daily see figure 3.1. The drain on the pre-filter (particulate) is

automatic, but still needs to be checked daily to make sure it is “dumping” all the water.

The particulate air filter will require cleaning at intervals dependent on the quantity of

impurities in your air supply. The secondary filter (coalescing) is designed to remove very

small impurities and oils from the air. This filter must be replaced when the element

appears discolored or dirty. NOTE: A DISCOLORED COALESCING FILTER

INDICATES A POSSIBLE PROBLEM WITH THE UPSTREAM AIR SUPPLY

5.6 REGULATOR

Set regulator at 90 PSI

When changing router bits ALWAYS disconnect the router cord from the receptacle first.

Keep all cutting tools sharp. Dull cutterheads, router bits or drill bits will not only do

shabby work, they shorten the life of essential parts of your machine.

��

57

5.7 AIR TOOL LUBRICATOR

Set lubricator to drop (2-4) drop per minute, with one air tool running. This is not a critical

adjustment, but excess oil in the air serves no useful purpose. Use 10 wt. turbine oil to refill

the lubricator.

5.8 CYLINDERS

Keep cylinder shafts clean to prevent excess wear. As seals in all cylinders will take a “set”

when not operating, cylinder manufacturers strongly recommend that all cylinders be cycled

at least two times each morning before placing a door and jamb in the machine. This will

allow the cylinder seals to regain natural sealing ability and will lengthen cylinder life

considerably.

5.9 SANDER BELT

Inspect the sander drive belt weekly for tightness, cracks or hard spots at the splice. When

adjusting the tension of the belt it is important not to over tighten the sander double V-belt

as this will severely shorten the life of the belt.

5.10 BEARINGS

Inspect the bearings of the cutterhead and sander weekly. Check for noise, play, and

smoothness of operation.

5.11 LUBRICATION OF BEARINGS AND BUSHINGS

With the exception of adding oil to the Lubricator no lubrication is required. All bearings

are pre-lubricated and sealed: All bushings are self-lubricating 'Nylatron' or 'Oilite'.

Note: Bushing life will be lengthened by keeping slide rods clean. Never use oil, graphite or

silicone spray on the bushings of any assembly of your machine to “free” it up. Any foreign

substance such as those above will collect fine sawdust and dirt particles which will tend to

wear the bushings very quickly. If any assembly is binding, and you have kept the

mechanisms clean, the problem is most likely that the parts have become misaligned.

Do not use hydraulic fluid, oil containing additives or any substance

not recommended by Norfield as this may cause damage to the

machine and possibly void your warranty.

6.1 PREFACE

The first portion of this section is to help familiarize you with the operation of the Magnum

by briefly describing what actually happens (mechanically, pneumatically and electrically)

when you “push the button”, refer to Figure 6.1 for additional assistance. The second and

third portions of this section deals with troubleshooting the machine.

6.2 DRILL CYCLE SEQUENCE

Before the drill cycle sequence can start, the operator must first depress the foot clamp

pedal to clamp the door. The activation of the foot clamp pedal also enables the drill cycle

pedal to operate. This is a safety feature: it prevents the operator from inadvertently ruining

a door by attempting to drill it before it is clamped.

To start the drill cycle, the operator presses the drill start foot pedal. If the latch drill is fully

retracted and the latch drill home position sensor is on, the lock drill valve is then activated

by the controller. When the lock drill stroke is far enough out to activate the lock drill

return sensor the controller turns the lock drill valve off, and the lock drill returns. When

the lock drill has returned the lock drill home position sensor is turned on which then

enables the latch drill sensor valve to turn on supplying air to the latch drill cylinder and it

begins its stroke. When the latch drill has extended to activate the latch drill return sensor

the latch drill valve is turned off, returning the latch drill to its home position. Opening the

clamps at any time during this cycle will immediately turn off the valve that is on, returning

the drills to their home position and resetting the cycle to the off position.

The flow control valve and controls the speed at which the cylinder retracts and extends

meter when air is fed into either the lock drill or latch drills cylinders, the air escaping the

cylinder.

The setting of the lock drill flow control valve determines how fast the lock drill will bore

through the door. Drilling time should be 4 seconds. If it is faster, there is danger of

overloading the lock drill motor. On certain doors with hardwood drill blocks, a longer

drilling time may be required.

As the drill sequence occurs the output and input lights on the controller turn on and off as

various actions occur, these lights can be a invaluable troubleshooting help. As an example,

if you step on the cycle start pedal and the foot pedal light on the controller does not come

on when the pedal is engaged, then the controller is not getting the start input, and the

machine will not cycle, Taking a close look at the cycle start foot pedal switch is warranted.


60


To assist you in determining the cause of a problem when it occurs, we have labeled and

identified all inputs and outputs of the controller modules. The labeling and lights should be

clearly visible through the window on the operator control panel.

As the controller turns functions on and off, output lights on the controller or expansion

module turn on and off, the pneumatic control valves also have a indicator light that come

on when they are activated. If the controller is providing an output the corresponding

control valve light should be on.

To assist in trouble shooting the following figure will identify which pneumatic control

valve powers, which function on the machine.

6.3 WIDTH INDEX SPEED CONTROLLER

The speed controller is located in the lower left corner of the main electrical panel. This

unit controls the width index motor speeds (fast, slow, up and down). This unit is not

serviceable. The speed controller is programmed at the factory with the right parameters for

your magnum. If you should have any problems with the speed controller unit, a code will

be displayed. Look through the small window on the main electrical panel and record the


FIG. 6.3

��

63


code for future reference. This code will help in finding a possible problem with your

magnum. After the code is recorded you can reset the speed controller by turning off the

main disconnect switch for 5 seconds. Below is a list of possible error codes for the speed

controller:

1. OC1 - OVER CURRENT SHUT DOWN (DURING ACCELERATION)

2. OC2 - OVER CURRENT SHUT DOWN (DURING CONSTANT SPEED)

3. OC3 - OVER CURRENT SHUTDOWN (DURING DECELERATION)

4. THM - CONTROLLER OVERHEATING OR MOTOR OVERLOAD

5. OLT - STALL PREVENTION

6. UV - INSUFFICIENT VOLTAGE WARNING (THIS ERROR IS SELF CORRECTING

OPERATION WILL RETURN WHEN THE CORRECT VOLTAGE IS RESTORED)

If a code is displayed other than the above, or if a code appears

repeatedly. Call NORFIELD SERVICE for assistance. !
