SINGLE 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.

CODE COLOR KEY:
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.
MEANING
SOLUTION
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
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.
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
Failure or missing EXIT loop
Check loop wiring throughout connection. May be a short in the
loop, or an open connection in the loop (LiftMaster Plug-in Loop
Detector only).
44
Failure or missing SHADOW
loop
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.
50
Run-Distance Error
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.
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.
54
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.
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

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
Look for obstruction, if no obstruction, check that the mechanical
assembly is engaged and free to move. Refer to manual for Limit
and Force Adjustment, and Obstruction Test.
93
RPM / STALL Reversal
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.
95
AC motor no start condition
Motor failed to start. Check for an obstructed gate or binding
mechanism. Check start capacitor connections and condition.
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
