•
Run the operator a few cycles:
◦
Make sure that the door rollers are rolling smoothly on the track.
◦
Listen to the motor: The motor should hum quietly and smoothly.
◦
Verify that the limits operate quietly and smoothly: investigate any unusual noise.
•
Verify that the mounting bolts are holding the unit securely.
•
Inspect the unit for evidence of corrosion.
•
Change the gear reducer's oil, at the very least, after every
2500 hours
of operation or once a
year (if applicable).
1.2
Electrical Inspection
It is recommended that the electrical maintenance inspections be performed at the same intervals as the mechanical
maintenance inspections.
Table 13 - Electrical Inspection
Time Frame
Inspection
Every Month
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.
Verify that the pneumatic edge or other entrapment protection devices installed on the
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.
