5 SCHEDULED MAINTENANCE

Maintenance and supervision should be performed by qualified persons only.
Inspection and service should be performed anytime a malfunction is observed or suspected.
WHEN SERVICING - ALWAYS DISCONNECT OPERATOR FROM POWER SUPPLY
5.1 MECHANICAL
The door area should always be kept clear of dirt, rocks or any other substance to insure proper operation.
- Check and adjust the brake band and solenoid, if needed.
EVERY 3 MONTHS - Check and adjust the clutch, if necessary.
- Check all safety features if responding properly (photocells, pneumatic etc)
- Check the oil level in the gearbox.
- Lubricate all moving parts, bushings are oil impregnated and are lubricated for life.
- Verify that all mechanical parts function properly.
EVERY 6 MONTHS
- Inspect the V-belt and adjust or replace if necessary.
- Manually operate the door. If the door does not open or close freely, correct the
cause of the malfunction.
- Inspect all bolts and screws and tighten if necessary.
- Check for any excessive slack in chains and adjust or replace them if necessary.
The limit switches may have to be reset after a chain adjustment.
- Inspect the door for wear and damage.
- Run the operator a few cycles:
ONCE A YEAR
- Verify that the mooring bolts are holding the unit securely.
- Inspect the unit for evidence of corrosion.
5.2 ELECTRICAL
BEFORE OPENING THE CONTROL BOX COVER, DISCONNECT OPERATOR FROM POWER SUPPLY

Inspect the unit for evidence of corrosion.

Inspect the wiring compartment and remove any dirt from the control units.

Check all the grounding wires and terminations for corrosion. Be particularly careful to check the ground wires.

Check the terminal strip to insure that all the screws are tight.

Verify that the safety edge or other safety devices installed on the operator are fully operational.

Check 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, the contact points will wear
prematurely and may eventually weld. Check the power terminations for corrosion.

Check the current consumption of the unit with an amp-meter. The value of current should be consistent with the
nameplate specifications. Investigate any anomaly
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 limit operates quietly and smoothly: investigate any unusual noise.
