TROUBLESHOOTING

IMPORTANT: Only qualified personnel should service internal components or electrical wiring.

TROUBLESHOOTING GEAR MOTORS

Basically, Gear motor problems can be narrowed down to three areas of checkout.

The Gearmotor Will Not Run

1. No voltage to the transmission terminals – check external circuit.

2. Low voltage – check voltage supply.

3. Problems in the gear motor electrical circuit. See Figure 4.

The Gearmotor Starts but Trips Repeatedly On The Overload Protector

1. Voltage – high or low voltage can cause the overload to trip.

2. High Gear motor amperage draw, see Specification Chart for ratings and Troubleshooting Guide.

The Motor Runs but Output Shaft Does not Rotate

Replace defective gear motor.

WARNING:

Be sure unit is disconnected from the power source. Disconnect the transmission cable.

OVERLOAD CHECK:

1. Allow motor to cool and reset overload if necessary.

2. Remove motor end bell and stator, if necessary.

3. Check terminals 1 and 3 on overload. No continuity replace overload. Use a volt–ohm meter. See Figure 4 and
