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 gear box (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.

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 44.

 

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 27 under "possible

 

 

cause" listing "Conveyor gear motor".
