Diagnostic Chart
1 FLASH | Symptom: One or both of the Indicator lights on the safety reversing sensors | ||
Safety reversing sensors | do not glow steady. | ||
• Inspect sensor wires for a short (staple in wire), correct wiring polarity (black/white | |||
wire open (broken or | |||
wires reversed), broken or disconnected wires, replace/attach as needed. | |||
disconnected). | • Disconnect all wires from back of motor unit. | ||
| OR | ||
| • Remove sensors from brackets and shorten sensor wires to | ||
|
| back each of sensor. | |
2 | FLASHES | ||
• Reattach sending eye to motor unit using shortened wires. If sending eye indicator | |||
Safety reversing sensors | light glows steadily, attach the receiving eye. | ||
• Align sensors, if the indicator lights glow replace the wires for the sensors. If the | |||
wire shorted or | |||
black/white wire reversed. | sensor indicator lights do not light, replace the safety reversing sensors. |
3 | FLASHES | Symptom: LED is not lit on door control. | |
Door control or | • Inspect door control/wires for a short (staple in wire), replace as needed. | ||
• Disconnect wires at door control, touch wires together. If motor unit activates, | |||
wire shorted. | |||
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, replace door control wires. |
4 | FLASHES | Symptom: Sending indicator light glows steadily, receiving indicator light is | |

|
|
•If motor unit doesn’t operate, motor unit is overheated. Wait 30 minutes and retry. If motor unit still will not operate replace logic board.
9 | FLASHES | Symptom: Door reverses while closing. | |
Cable tension | • Check for possible door obstructions and remove. | ||
• Check that the cable tension monitor is properly connected to the operator. | |||
