WARNING To reduce the risk of INJURY or DEATH: CAUTION • DISCONNECT power and battery BEFORE installing or servicing operator. • Replace ONLY with fuse of same type and rating. • To be compliant with UL325 and industry safety guidelines, qualified monitored WARNING external entrapment protection devices such as photoelectric sensors or edge sensors are required to be installed with this operator at each entrapment zone. Use ONLY LiftMaster approved entrapment protection devices (refer to the accessory page of manual). WARNING • See manual prior to servicing regarding maintenance and required safety testing. Diagnostic Codes TO VIEW THE CODES: Press and hold STOP... ...then press and hold CLOSE... ...then press and hold OPEN until "Er" shows. The operator will show the code sequence number followed by the code number: A SECOND LATER.... CODE SEQUENCE NUMBER The first number shown is the most recent code (example: "01"). The display will show the sequence of codes that occurred starting with "01" and going up to code "20". CODE NUMBER The second number shown after the code sequence number is the code itself (31-99, example" "31"). CODE COLOR KEY: LiftMaster System Installed System Informational External Entrapment Protection Inherent Entrapment Protection CODE MEANING SOLUTION Main control board has experienced an internal Disconnect all power, wait 15 seconds, then 31 failure. reconnect power (reboot). If issue continues, replace main control board. 32 Linear Drive Disengaged (Arm 1) 33 Linear Drive Disengaged (Arm 2) Disengage then re-engage arm. Check wiring and connections. 34 Absolute Position Encoder Error, not getting position information from encoder Check the operator cable connections, then reprogram the limits. 35 Max-Run-Time Exceeded Error Check for an obstruction, then reprogram the limits. Product ID Error 36 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 37 Unplug product ID harness then plug back in. Disconnect all power, wait 15 seconds, then reconnect power before replacing product ID harness. 38 Hard Stop Limit (Arm 1) 39 Hard Stop Limit (Arm 2) Limit may be set too tightly against a nonresilient hard stop (re-adjust limit). Operator may be at end of travel (re-adjust mounting). Battery overvoltage 40 Too much voltage on the battery. Check harness. Make sure there is NOT a 24V battery on a 12V system. Battery overcurrent 41 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 42 Check battery connections and installation. Replace batteries if depleted to less than 20V on a 24V system or less than 10V on a 12V system. Make sure there is NOT a single 12V battery on a 24V system. 43 Exit Loop Error 44 Shadow Loop Error Interrupt Loop Error 45 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. 46 Wireless edge battery low Replace batteries in wireless edge. Run-Distance Error 50 Gate unbalance detected. Make sure the gate is installed on a level surface and not on an excessive grade. 51 Pass-point not detected (Arm 1) 52 Pass-point not detected (Arm 2) Check yellow pass-point wiring. If limits are not accurate, reprogram. Brownout occurred 53 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, 54 restore power and try to run the system. If powered, deactivate the wireless feature and then reprogram the second operator. Minimum number of monitored entrapment Review monitored entrapment protection device protection devices not installed. connections. This swing gate operator will 60 operate only after installation of a minimum of one external safety device in either the open or close 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. 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. Wireless edge triggered 69 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 71 CLOSE EDGE triggered, causing reversal, preventing close, or canceling TTC IF an obstruction occurred, no action required. If an obstruction did NOT occur, check alignment, inputs, and wiring on main control board. 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, 74 CLOSE EYE/EDGE triggered, causing reversal and preventing close or canceling TTC inputs, and wiring on expansion board. 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. Open input (EYE/EDGE) communication fault Ensure operator is powered. May have to erase 81 from other operator the wireless communication and reprogram the two operators. 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) Non-monitored device detected on the wireless Non-monitored contact closure devices are not 84 safety system supported. Make sure connected devices are monitored. Check edges for proper orientation and resistive end cap connection. 91 Force Reversal (Operator 1) Force Reversal (Operator 2) 92 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 in the manual. 93 RPM / STALL Reversal (Operator 1) RPM / STALL Reversal (Operator 2) 94 Check for obstruction. If no obstruction, check the operator wiring and that the mechanical assembly is engaged and free to move. Replace APE assembly. 99 Normal Operation No action required WIRING DIAGRAM Model CSW24UL COAXIAL CABLE ANTENNA Control Board DIAGNOSTICS LOOPS CONTROLS Jumper N.C.
