INITIAL TROUBLESHOOTING STEPS (ANY INOPERATIVE FUNCTION)
IF YOU ARE EXPERIENCING AN ELECTRICAL PROBLEM (OR ARE UNSURE WHAT
THE PROBLEM IS) CHECK THE FOLLOWING BEFORE PROCEEDING:
CHECK THE MAIN POWER SUPPLY - MAKE SURE THAT THE MASTER DISCONNECT SWITCH
IS
ON.
CHECK THE PENDANT CORD PLUG - MAKE SURE IT IS SECURELY PLUGGED IN.
THE MOST COMMON ELECTRICAL PROBLEM IS INSUFFICIENT VOLTAGE. YOU
CAN VERIFY SUFFICIENT SOURCE VOLTAGE BY REFERRING TO SERVICE
BULLETIN
800306 “MINIMUM VOLTAGE TEST” IN THIS INSTALLATION MANUAL.
IF YOU ARE UNABLE TO PERFORM THIS TEST (i.e. THE POWER UNIT WILL NOT
FUNCTION) SKIP TO THE NEXT STEP.
CHECKING FOR SUFFICIENT CONTROL VOLTAGE AT THE PENDANT SOCKET:
REMOVE THE PENDANT CONTROL FROM THE CRANE AND PROP OPEN THE PENDANT
SOCKET LID.
TURN ON THE MASTER DISCONNECT SWITCH.
LOCATE THE POWER SUPPLY PIN ("HOT PIN") FOR THE SOCKET - SEE FIGURE 1 BELOW.
WITH A MULTIMETER/VOLTMETER MEASURE THE VOLTAGE AT THE "HOT PIN". THIS
SHOULD BE SOURCE VOLTAGE MEASURING 12 VOLTS DC.
PENDANT CONTROL BYPASS PROCEDURE
IF THE PENDANT CORD IS SUSPECT, YOU CAN JUMPER THE “HOT PIN” TO ANY OF THE
FUNCTION PINS (i.e. WU = WINCH UP, BD = BOOM DOWN, ETC.) TO VERIFY WHETHER
THE PROBLEM IS IN THE PENDANT CONTROL OR THE CRANE WIRING.
