TROUBLESHOOTING CONTROL BOARD LEDS CONTROL BOARD LEDS # BLINKS 1 BLINK 2 BLINKS 3 BLINKS 5 BLINKS 6 BLINKS 7 BLINKS 12 BLINKS DIAGNOSTIC CODES LEDS YELLOW DIAGNOSTIC LED MEANING CORRECTION Low Power Mode (not an error) ID resistor failure Check ID resistor wiring, clear limit settings and reset limits Exceeded Maximum Check gate travel, if necessary adjust Run Timer force setting RPM (obstruction) Check for obstruction, if necessary adjust force setting Current (obstruction) Check for obstruction, if necessary adjust force setting Position failure Check gate travel, clear limit settings and reset limits 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.
