Table 13 - Electrical Inspection
Time Frame

Inspect the unit for evidence of corrosion on electrical wires and connectors.

Inspect the wiring compartment and remove any dirt from the control units.

Verify all the grounding wires and terminals for corrosion. Be particularly careful to verify the
ground wires.

Verify the terminal strips to insure that all the screws are tightened.

Every Month
operator are fully operational.

Verify the voltage at the input terminals while the operator is running. The voltage must not drop
more than 10% momentarily. If the voltage drop is too deep when running, the relays may
chatter and the contact points will wear prematurely and may eventually seize. Verify the power
terminals for corrosion.

Verify the current consumption of the unit with an amp-meter. The current value should be
consistent with the nameplate specifications. Investigate any anomaly.
