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”).

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.

32

Linear Drive Disengaged (Arm 1)

Disengage then re-engage arm. Check wiring and

connections.

33

Linear Drive Disengaged (Arm 2)

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.

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.

38

Hard Stop Limit (Arm 1)

Limit may be set too tightly against a non-

resilient hard stop (re-adjust limit). Operator may

be at end of travel (re-adjust mounting).

39

Hard Stop Limit (Arm 2)

40

Battery overvoltage

Too much voltage on the battery. Check harness.

Make sure there is NOT a 24V battery on a 12V

system.

41

Battery overcurrent

Possible short of the battery charge harness.

Check harness. Make sure you do NOT have a

12V battery on a 24V system.

42

No battery at boot up

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

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.

50

Run-Distance Error

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)

Check yellow pass-point wiring. If limits are not

accurate, reprogram.

52

Pass-point not detected (Arm 2)

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

reprogram the second operator.

60

Minimum number of monitored entrapment

protection devices (one) not installed.

Review monitored entrapment protection device

connections.

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.

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


an obstruction did NOT occur, check alignment,

inputs, and wiring on main control board.

71

CLOSE EDGE triggered, causing reversal,

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


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)

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 in the manual.

92

Force Reversal (Operator 2)

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.

94

RPM / STALL Reversal (Operator 2)

99

Normal Operation

No action required

WARNING

•

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

external entrapment protection devices such as photoelectric sensors or edge

sensors are required to be installed with this operator at each entrapment zone.

•

See manual regarding maintenance and required safety testing prior to servicing.
