DC Motor Control Board

Check for 120 VAC input to the control board at

 

 

terminals L1 and L2. If not present, check the

 

 

conveyor switch and wiring back to 3-amp fuse and

 

 

then back to power source if necessary. If 120 VAC

 

 

is present at L1 and L2, check the VDC output at

 

 

terminals A+ and A-. If a DC voltage is not present,

 

 

check the 4 amp and the 1 amp fuses on the

 

 

control board. Also reset and check the mini

 

 

breaker in the armature line to the gearmotor. If

 

 

120 VAC is present at terminals L1 and L2, but DC

 

 

voltage is not present at A+ and A-, providing the 1

 

 

amp and 4 amp fuses are good, replace the board.

 

 

If DC voltage is present at A+ and A-, but motor

 

 

does not run, check gear motor as follows.

 

Conveyor Gear Motor

If DC voltage is present at A+ and A- and the motor

 

 

does not run, first check the mini breaker and then

 

 

the conveyor. Refer to the next possible cause.

 

 

Check the leads to the motor for evidence of any

 

 

shorts or opens, and each lead to ground. If the

 

 

motor fails the above tests, replace motor. Remove

 

 

dust cover from the top of the motor and rotate

 

 

motor shaft to determine if there is a locked rotor or

 

 

a locked gearbox (use care so encoder disc is not

 

 

damaged).

 

Conveyor

Check for any mechanical misalignment or

 

 

improper adjustment. Also check for worn bearings.

 

 

The Installation and Operations Manual shows

 

 

proper conveyor belt adjustment. A conveyor belt

 

 

that is over tightened will cause excessive bearing

 

 

wear and sometimes, irregular speed.

Conveyor speed

Power Supply

Check power supply at the DC control board for the

varying or intermittent

 

120 VAC at board terminals L1 and L2. If voltage is

 

 

not present, check main circuit breakers.

 

Tach generator and DC Motor

With the power to the DC motor control board

 

Control Board

turned off, remove the leads from terminals T1 and

 

 

T2.Place the test leads of a digital meter on the

 

 

tach leads, turn power on, and the meter reading

 

 

should be approximately 30 to 35 VDC. This

 

 

reading should be steady within ± 0.2 to 0.3 VDC. If

 

 

this reading is not within + 0.5 VDC, place the test

 

 

meter probes on terminals A+ and A-. The meter

 

 

reading should be approximately 150 to 160 VDC

 

 

and steady within approximately 2 VDC. If the tach.

 

 

voltage is unsteady, and the board output is steady,

 

 

check the coupling for loose set screws or any type

 

 

of damage. If the coupling checks good, the tach. is

 

 

usually bad. If the board voltage output is unsteady

 

 

beyond limits, then the board is probably bad.

 

 

Always check the speed pot. Be sure it is okay

 

 

before changing a board or tach. This test is not

 

 

always 100% accurate as this test is not performed

 

 

at operating speeds. However, this test is the best

 

 

method currently available. Readjustment should

 

 

always be attempted at least once before

 

 

replacement. See procedure for board adjustment

 

 

on page 65.

 

DC Gearmotor

If the DC control board is steady then the problem

 

 

may be the motor or gearbox. Check the brushes in

 

 

the motor for excessive arching and/or unusual

 

 

wear. Check the motor and gearbox from

 

 

instruction located on page 34 under "possible

 

 

cause" listing "Conveyor gear motor".
