! USE EXTREME CAUTION when performing tests on energized circuits.

WARNING:

! When repairing a circuit, disconnect the power at the main service disconnect switch and place a tag at the disconnect switch to indicate that work is being performed on the circuit.

Troubleshooting

Schematics

Moyer Diebel places an electrical schematic in the control cabinet of every machine before it is shipped. Schematics are included at the back of this manual as well. Be aware that these schemat- ics include options that may not apply to your machine. Options are enclosed in dashed lines with the words (IF USED) next to them on the schematic. Disregard any options that appear on the schematics which are not a part of your machine.

Tools

All electrical repairs can be made with:

Standard set of hand tools Volt/Ohm Meter (VOM) Clip-on AC current tester

Circuit Tests

Use a clip-on AC current tester to check the motors and electric heaters. Use a VOM to test line voltages and the 115VAC control circuit.
