1 FLASH

Safety sensors wire open (broken or disconnected).

OR

2 FLASHES

Safety sensors wire shorted or black/white wire reversed.

3 FLASHES

Door control or wire shorted.

4 FLASHES

Safety Sensors slightly misaligned (dim or flashing LED).

5 FLASHES

Motor overheated or possible RPM sensor failure. Unplug to reset.

6 FLASHES

Motor Circuit Failure.Replace ReceiverLogic Board.

Symptom: One or both of the Indicator lights on the safety sensors do not glow steady.

ïInspect sensor wires for a short (staple in wire), correct wiring polarity (black/white wires reversed), broken or disconnected wires, replace/attach as needed.

ïDisconnect all wires from back of motor unit.

ïRemove sensors from brackets and shorten sensor wires to 1-2 ft. (30-60 cm) from back each of sensor.

ïReattach sending eye to motor unit using shortened wires. If sending eye indicator light glows steadily, attach the receiving eye.

ïAlign sensors, if the indicator lights glow replace the wires for the sensors. If the sensor indicator lights do not light, replace the safety sensors.

Symptom: LED is not lit on door control.

ïInspect door control/wires for a short (staple in wire), replace as needed.

ïDisconnect wires at door control, touch wires together. If motor unit activates, replace door control.

ïIf motor unit does not activate, disconnect door control wires from motor unit. Momentarily short across red and white terminals with jumper wire. If motor unit activates, replace door control wires.

Symptom: Sending indicator light glows steadily, receiving indicator light is dim or flashing.

ïRealign receiving eye sensor, clean lens and secure brackets.

ïVerify door track is firmly secured to wall and does not move.

Symptom: Motor has over heated; the motor unit does not operate or trolley is stuck on stop bolt = Motor unit hums briefly; RPM Sensor = Short travel 6-8" (15-20 cm).

ïUnplug unit to reset. Try to operate motor unit, check diagnostic code.

ïIf it is still flashing 5 times and motor unit moves 6-8" (15-20 cm), replace RPM sensor.

ïIf motor unit doesnít operate, motor unit is overheated. Wait 30 minutes and retry. If motor unit still will not operate replace logic board.

Symptom: Motor unit doesn’t operate.

ïReplace logic board because motor rarely fails.
