Sec-5.4
Section 5: Troubleshooting
To aid in troubleshooting problems, this operator includes an error code memory that stores the most recent 10 error
events. These codes are stored with or without power. The latest error code detected is also displayed on the lcd until
the stop button or key is pressed or the operator stops at the down limit.
The error code memory stores its codes in time sequence. Once 10 codes are stored, the oldest code will be erased to
make room for the next newest code. These codes are displayed in calibration mode. The display will flash the number
of the code in the sequence and the 2 digit code id, followed by a description of the code.

Check the door balance. Check the Clutch adjustment to
make sure it's not slipping. Check for mechanical issues.
Replace the Limit Module. Replace the Main Control
Board.
4A
REV > LOSS OF C/C
The door stopped traveling down and reversed because the
constant contact activation was removed before the door
reached the down limit.
User input was removed.
