LiftMaster System Installed System Informational External Entrapment Protection Inherent Entrapment Protection Code 66 67 68 69 70 71 72 73 74 75 80 81 82 83 91 93 95 99 Meaning OPEN EYE/EDGE held more than 3 minutes (expansion board) Wireless edge triggered more than 3 minutes Wireless edge loss of monitoring Wireless edge triggered CLOSE EYE/INTERRUPT triggered, causing reversal, preventing close, or resetting TTC (main board) CLOSE EDGE triggered, causing reversal, preventing close, or canceling TTC (main board) OPEN EYE/EDGE triggered, causing reversal or preventing opening (main board) CLOSE EYE/INTERRUPT triggered, causing reversal, preventing close, or resetting TTC (expansion board) CLOSE EYE/EDGE triggered, causing reversal and preventing close or canceling TTC (expansion board) OPEN EYE/EDGE triggered, causing reversal or preventing opening (expansion board) Close input (EYE/EDGE) communication fault from other operator Open input (EYE/EDGE) communication fault from other operator Close input (EYE/EDGE) communication fault (expansion board) Open input (EYE/EDGE) communication fault (expansion board) Force Reversal RPM / STALL Reversal AC motor no start condition Normal Operation Solution Check wired input on expansion board; check for alignment or obstruction. Check wired input for wiring issue or obstruction. Check wireless edge inputs. IF an obstruction occurred, no action required. If an obstruction did NOT occur, check inputs and wiring. IF an obstruction occurred, no action required. If an obstruction did NOT occur, check alignment, inputs, and wiring. IF an obstruction occurred, no action required. If an obstruction did NOT occur, check alignment, inputs, and wiring. IF an obstruction occurred, no action required. If an obstruction did NOT occur, check alignment, inputs, and wiring. IF an obstruction occurred, no action required. If an obstruction did NOT occur, check alignment, inputs, and wiring. IF an obstruction occurred, no action required. If an obstruction did NOT occur, check alignment, inputs, and wiring. IF an obstruction occurred, no action required. If an obstruction did NOT occur, check alignment, inputs, and wiring. Check inputs and communication method between operators, either wired bus or radio. Ensure operator is powered. May have to erase the wireless communication and reprogram the two operators. Check inputs and communication method between operators, either wired bus or radio. Ensure operator is powered. May have to erase the wireless communication and reprogram the two operators. Check the connections between the main board and the expansion board. Check the connections between the main board and the expansion board. Look for obstruction, if no obstruction, check that the mechanical assembly is engaged and free to move. See section on Limit and Force Adjustment, and Obstruction Test. Check for obstruction. If no obstruction, check the operator cable wiring and that the operator arm is engaged and free to move. Replace RPM assembly. Motor failed to start. Check for an obstructed gate or binding a mechanism. Check start capacitor connections and condition. No action required Saved YES YES YES NO NO NO NO NO NO NO YES YES YES YES YES YES YES YES 24
