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
