TROUBLESHOOTING & DIAGNOSTICS

BEEPS EXPLANATION SOLUTION
2 Beeps Over Voltage > 30V unit will shut down. Check voltage & adjust to 24 V.
3 Beeps Under Voltage < 20V unit will shut down. Check voltage & adjust to 24 V.
4 Beeps Failed Sensor Verify all 3 sensor wires are installed correctly. Replace sensor if problem persists by contacting office.
5 Beeps Retraction or dogging failure After 1st fail: 5 beeps then immediately attempts to retract again. After 2nd fail: 5 beeps with pause in-between for 30 seconds then device attempts to retract again. After 3rd fail: 5 beeps every 7 minutes, device will not attempt to retract. To Reset: Depress bar for 5 seconds at any time.
6 Beeps PUSH TO SET Device is recording it's new position and power mode after the 6th beep.

*FOR MM4T *Latch bolt adjustment- If the latch bolt is not retracting far enough, turn the dial clockwise with a small flat blade screw driver. If the latch bolt is retracting too far causing the device to chatter and drop-out, turn the dial counter-clockwise until the chatter and drop-outs stop and the desired location is achieved.
