9.
OVERLOAD SHUTDOWN SYSTEM DOES NOT OPERATE PROPERLY (CONT).
Step 5. Check for proper spooling on hoist drum (1) of the hoist cable (2). It is essential for the correct
operation of the Overload Shutdown System (3) to have the hoist cable spooled properly. The
Overload Shutdown System cannot accurately determine the amount of extended cable if
the cable is not spooled evenly or “birdnested”.
If the hoist cable is not spooled properly, refer to Fault 6, Hoist Does Not Spool
Cable Properly.
If the hoist cable is OK, notify Unit Maintenance.
