YELLOW DIAGNOSTIC LED
# BLINKS MEANING CORRECTION
2 BLINKS ID resistor failure Check ID resistor wiring, clear limit
settings and reset limits
3 BLINKS Exceeded Maximum
Run Timer
Check gate travel, if necessary adjust
force setting
5 BLINKS RPM (obstruction) Check for obstruction, if necessary
adjust force setting
6 BLINKS Current (obstruction) Check for obstruction, if necessary
adjust force setting
7 BLINKS Position failure Check gate travel, clear limit settings
and reset limits
12 BLINKS Loop Error One of the loops is in error. Refer to the
loop detector to determine the error.
RED DIAGNOSTIC LED
# BLINKS MEANING CORRECTION
2 BLINKS Current Sense Motor control circuit fault, replace
control board
3 BLINKS FET Failure Motor control circuit fault, replace
control board
4 BLINKS RAM Failure Memory failure, replace control board
5 BLINKS Flash Memory
Failure
Memory failure, replace control board
6 BLINKS EEPROM Failure Memory failure, replace control board
7 BLINKS Watchdog Failure Controller failure, replace control
board
8 BLINKS Brownout Check power harness or line voltage
9 BLINKS Fail Control Board failure
10-14 BLINKS Software Failure Cycle power to the control board. If
continues replace control board.
