The "Learn" button/diagnostic LED will flash a number of times then pause
signifying it has found a potential issue. Consult Diagnostic Chart below.
•0 Symptom:One orboth of the Indicatorfightson the safetysensorsdo notglow steady.
• Inspect sensorwires for a short (staple in wire), correct wiring polarity (black/white
wires reversed), broken or disconnected wires, replace/attachas needed.
• Disconnectall wires from back of motor unit.
• Removesensors from brackets and shorten sensor wires to 1-2 ft (30-60 cm) from
back each of sensor.
• Reattachsending eyeto motor unit using shortenedwires. If sending eye indicator
light glows steadily, attach the receiving eye.
• Align sensors, if the indicator lights glow replacethe wires for the sensors. If the
sensor indicator lights do not light, replacethe safety sensors.
•Q Symptom:LEDis not lit ondoorcontrol.
• Inspect door control/wires for a short (staple in wire), replace as needed.
• Disconnectwires at door control, touch wires together. If motor unit activates,replace
door control.
• If 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, replacedoor control wires.
•Q Symptom:Sendingindicatorlight glowssteadily, receivingindicatorlight is dim or
flashing.
• Realignreceiving eye sensor, clean lens and secure brackets.
• Verify door track is firmly securedto wall and does not move.
•Q Symptom:Motorhas overheated;the motor unit doesnotoperate or trolleyis stuckon
stopbolt = Motorunit humsbriefly;RPM Sensor= Shorttravel 6-8" (15-20 cm).
• Unplug unit to reset. Try to operate motor unit, check diagnostic code.
• If it is still flashing 5 times and motor unit moves6-8" (15-20 cm), replace
RPMsensor.
• If motor unit doesn't operate, motor unit is overheated.Wait 30 minutes and retry. If
motor unit still will not operate replacelogic board.
•0 Symptom:Motorunit doesn'toperate.
• Replacelogic board becausemotor rarely fails.
