Disconnect all power, wait 15 seconds, then reconnect power (reboot). If issue continues, replace control board. Absolute Position Encoder Error, not getting position information from encoder Check the operator cable connections, then reprogram the limits. Max-Run-Time Exceeded Error Check for an obstruction, then reprogram the limits. Product ID Error Was the control board just replaced? If so, erase limits, enter limit setup mode and set limits. If not, disconnect all power, wait 15 seconds, then reconnect power before changing product ID harness. Product ID Failure Unplug product ID harness then plug back in. Disconnect all power, wait 15 seconds, then reconnect power before replacing product ID harness. Hard Stop Limit Limit may be set too tightly against a non-resilient hard stop (re-adjust limit). Operator may be at end of travel (re-adjust mounting). Battery overvoltage Too much voltage on the battery. Check harness. Make sure you do NOT have a 24V battery on a 12V system. Battery overcurrent Possible short of the battery charge harness. Check harness. Make sure you do NOT have a 12V battery on a 24V system. No battery at boot up Check battery connections and installation. Replace batteries if depleted to less than 20V on a 24V system. Make sure you do NOT have a single 12V battery on a 24V system. Loop Error - Failure or missing exit loop (SHORT Check loop wiring throughout connection. May be a short in the loop, or OPEN - LiftMaster Plug-in Loop Detector only) or an open connection in the loop. Loop Error - Failure or missing shadow loop (SHORT or OPEN - LiftMaster Plug-in Loop Detector only) Check loop wiring throughout connection. May be a short in the loop, or an open connection in the loop. Loop Error - Failure or missing interrupt loop (SHORT or OPEN - LiftMaster Plug-in Loop Detector only) Check loop wiring throughout connection. May be a short in the loop, or an open connection in the loop. Wireless edge battery low Replace batteries in wireless edge. Battery shorted Check battery harness for short to chassis Run-Distance Error Gate unbalance detected. Make sure the gate is installed on a level surface and not on an excessive grade. Brownout occurred AC/DC board supply dipped below allowable level. Review power supply and wiring. If rebooting, ensure enough time for discharge of power to force a fresh boot. Wireless Second Operator Communication Error Check the second operator for power. If OFF, restore power and try to run the system. If powered, deactivate the wireless feature and then re-learn the second operator. Minimum number of monitored entrapment protection devices (one) not installed. Review monitored entrapment protection device connections. CLOSE EYE/INTERRUPT held more than 3 minutes Check CLOSE EYE/INTERRUPT input on main board; check for (main board) alignment or obstruction. CLOSE EDGE held more than 3 minutes (main board) Check CLOSE EDGE input on main board; check for alignment or obstruction. OPEN EYE/EDGE held more than 3 minutes (main Check OPEN EYE/EDGE input on main board; check for alignment or board) obstruction. CLOSE EYE/INTERRUPT held more than 3 minutes Check wired input on expansion board; check for alignment or (expansion board) obstruction. CLOSE EYE/EDGE held more than 3 minutes (expansion board) Check wired input on expansion board; check for alignment or obstruction.
