Liftmaster SL3000101UL-1hp slide gate operator

31 Main control board has experienced an internal failure. Disconnect all power, wait 15 seconds, then reconnect power (reboot). If issue continues, replace main control board.
35 Max-Run-Time Exceeded Error Check for an obstruction, then reprogram the limits.
36 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.
37 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.
43 Exit Loop Error Failure or missing 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.
44 Shadow Loop Error
45 Interrupt Loop Error
46 Wireless edge battery low Replace batteries in wireless edge.
47 Power board fault Relay fault detected in the power board. Replace the power board.
50 Run-Distance Error The limits are less than the minimum requirement or longer than what was learned. Check limit positions and proper switch function. Run- distance can be re-learned by setting the handing again.

53 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.

54Wireless 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.
55 System AC Overvoltage Call utility.
56 System AC Undervoltage Check wiring and wire gauge to operator.
57 Limit Error - Stuck Switch Check switch for proper operation. Check harness for shorts. Replace if defective.
58 Limit Error - Wrong Switch Check motor wiring.
59 Missing Power Board Check harness for shorts. Check for presence of power board.

60 Minimum number of monitored entrapment protection devices not installed. Review monitored entrapment protection device connections. Slide gate operators require a minimum of two external safety devices; one in the close and one in the open direction.
61 CLOSE EYE/INTERRUPT held more than 3 minutes Check wired input on main control board; check for alignment or obstruction.
62 CLOSE EDGE held more than 3 minutes
63 OPEN EYE/EDGE held more than 3 minutes
64 CLOSE EYE/INTERRUPT held more than 3 minutes Check wired input on expansion board; check for alignment or obstruction. The photoelectric sensors may be installed too far apart.
65 CLOSE EYE/EDGE held more than 3 minutes
66 OPEN EYE/EDGE held more than 3 minutes
67 Wireless edge triggered more than 3 minutes Check wired input for wiring issue or obstruction.
68 Wireless edge loss of monitoring Check wireless edge inputs.
69 Wireless edge triggered IF an obstruction occurred, no action required. If an obstruction did NOT occur, check inputs and wiring.

70 CLOSE EYE/INTERRUPT triggered, causing reversal, preventing close, or resetting TTC  IF an obstruction occurred, no action required. If an obstruction did NOT occur, check alignment, inputs, and wiring on main control board

71 CLOSE EDGE triggered, causing reversal, NO preventing close, or canceling TTC
72 OPEN EYE/EDGE triggered, causing reversal or preventing opening
73 CLOSE EYE/INTERRUPT triggered, causing reversal, preventing close, or resetting TTC  IF an obstruction occurred, no action required. If an obstruction did NOT occur, check alignment, inputs, and wiring on expansion board.

74 CLOSE EYE/EDGE triggered, causing reversal and preventing close or canceling TTC
75 OPEN EYE/EDGE triggered, causing reversal or preventing opening
80 Close input (EYE/EDGE) communication fault from other operator 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.
81 Open input (EYE/EDGE) communication fault from other operator
82 Close input (EYE/EDGE) communication fault (expansion board) Check the connections between the main board and the expansion board.
83 Open input (EYE/EDGE) communication fault (expansion board)

84 Non-monitored device detected on the wireless safety system Non-monitored contact closure devices are not supported. Make sure connected devices are monitored. Check edges for proper orientation and resistive end cap connection.

91 Force Reversal (Operator 1) Check 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.

93 RPM / STALL Reversal (Operator 1) Check for obstruction. If no obstruction, check the operator wiring and that the mechanical assembly is engaged and free to move. Replace APE assembly.

95 AC motor no start condition Motor start sequence failed. If the gate and motor are NOT moving, or moving too slow, check for an obstructed gate, binding in the mechanism, and relay board and start capacitor connections. If the gate and motor ARE moving, failure is due to loss of the encoder signal. Check the encoder cup and sensor on the limit shaft, and wiring.

96 Current Sensor Fault A fault was detected on the current sensor. Make sure the current sensor is connected to the main control board. Check the current sensor harness for an open or short. The operator will need a power cycle to resume operation after correcting the fault. If the fault continues, replace the power board.

99 Normal Operation No action required
