THREE PHASE WIRING DIAGRAM Models SL585UL and SL595UL To reduce the risk of INJURY or DEATH: • DISCONNECT power 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 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). • 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"). TO SCROLL THROUGH THE SAVED CODES: Press the OPEN button to cycle to the most recent code ("01"). Press the CLOSE button to cycle to the oldest code (up to "20"). CODE COLOR KEY: LiftMaster System External Entrapment Protection Installed System Inherent Entrapment Protection Informational MEANING SOLUTION Main control board has 31 experienced an internal failure. Disconnect all power, wait 15 seconds, then reconnect power (reboot). If issue continues, replace main control board. Max-Run-Time Exceeded 35 Error Attempt to run and review for duration and obstructions. Max-Run-Time can be re-measured by saving one or both of the limits again. 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. 43 Failure or missing EXIT loop Check loop wiring throughout connection. May be a short in 44 Failure or missing SHADOW the loop, or an open connection in the loop (LiftMaster Plug- loop in Loop Detector only). 45 Failure or missing INTERRUPT loop 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. Run-Distance Error 50 Limits are less than 4 feet apart or longer than what was learned. Check limit positions and proper switch function. Run-distance can be re-learned by setting the handing again. 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 54 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. Minimum number of 60 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 Check wired input on main board; check for alignment or more than 3 minutes obstruction. 62 CLOSE EDGE held more than 3 minutes 63 OPEN EYE/EDGE held more than 3 minutes 64 CLOSE EYE/INTERRUPT held Check wired input on expansion board; check for alignment more than 3 minutes 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 Check wired input for wiring issue or obstruction. than 3 minutes 68 Wireless edge loss of monitoring Check wireless edge inputs. 69 Wireless edge triggered IF an obstruction occurred, no action required.

TO SCROLL THROUGH THE SAVED CODES:
Press the OPEN button to cycle to the most recent code ("01"). Press the CLOSE button
to cycle to the oldest code (up to “20”).
To reduce the risk of INJURY or DEATH:
DISCONNECT power 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
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).
See manual prior to servicing regarding maintenance and required safety testing.
