Units are not synchronized:

Improper Master/Slave program settings.

One gate braking to stop causes a fault in the other (moving) gate:

1.Both units are wired to the same circuit breaker.

2.Undersized power wires.

B. FAULT LISTThe following conditions can cause a fault:

1.Instantaneous motor overcurrent (left/right obstruction sense) due to an object physically obstructing the gate or gate track (UL325 requirement).

2.Average motor overcurrent (overload) caused by excessive motor current (UL325 requirement).

3.Interrupt Bar activation (edge sensor) due to physical contact with the edge sensor.

4.Inoperative motor caused by an open motor winding, broken or disconnnected input motor wires, thermal overload, or unsupervised motor (UL325 requirement).

5.Limit switch staying closed when gate is supposed to move, caused by a broken V-belt, defective limit switch, or defective limit cams.

6.Maximum motor run time exceeding 75 seconds.

A.If faults 1 through 3 occur only once during opening or closing, the gate reverses a few inches and stops. Fault may be cleared by removing the obstruction and cycling any command (Manual Inputs, FIRE, Cycle, Radio, EXIT).

B.If two sequential faults (a combination of faults 1 through 3 and Photo- Sensor activation) occur during opening or closing, gate stops and Obstruction Alarm sounds off for 5 minutes. Fault may be cleared by removing the obstruction and cycling Manual Inputs or FIRE.

C.If fault 4 occurs, gate stops and Obstruction Alarm sounds off for 5 minutes. Fault may be cleared by cycling Manual Inputs or FIRE.

D.If faults 5 through 6 occur, gate stops. Fault may be cleared by cycling any command.
