Symptom Items to check
Operator will not run 1. Be sure AC power switch is on.
2. Check if Power LED on circuit board is on.
Operator will not run 1. Activate Card Reader, Transmitter or Phone Entry. Look at
Power LED is ON circuit board inside Gate Operator and see if LED’s on
terminals 11 or 12 light up when device is activated.
2. Using a wire jumper, jump between terminals 11 & 20, gate
should open.
Gate opens short distance, 1. Check if the how much force is needed to stop the gate. It

gate can be stopped by less pressure the clutch may need
adjustment. (See Following Page)
2. While gate is moving, Check that the pulse counter LED
sensor is blinking at terminal #9 (on bi-parting gates both
counters must be blinking, terminals 9 & 10).
3. Turn OFF power and unlock the manual release and check
that the gate swings freely and that the hinges do not bind.

2. Check red LED on Reverse and Exit Loop Detectors. If on
then loop is holding gate open.
Gate starts to close 1. Check for binding of gate at point of reverse.
then reverses to open. 2. Check if the how much force is needed to stop the gate.
3. Check counter LED’s
4. Check Loop Detector LED’s to see if loop is sensing the
gate.
