System Maintenance

It is recommended that the following checks be performed on the system prior to each shift or crane 
operation to help prevent errors or malfunctions:

Crane Configuration and System Setup

The crane configuration defines the physical setup of the crane.  The system setup defines the load 
parameters for each configuration.  The data for these calculations are loaded in the capacity chart and 
installed in the crane’s computer prior to factory shipment.

WARNING!

ENSURE THAT THE CONFIGURATION CODE NUMBER IN THE DISPLAY CONSOLE WINDOW IDENTIFIES THE 
CRANE’S CONFIGURATION FOR THE CURRENT OPERATION.  IF IN DOUBT, SELECT THE CODE NUMBER 
AGAIN FOLLOWING THE STEPS OUTLINED IN THE CRANE OPTIONS AND SETUP CODES OUTLINED IN THIS 
MANUAL.

Extension Reel, Reel-Off Cable to Boom Tip, Extension Reel Cable to Computer

The extension reel houses the reel-off cable to the boom tip, a cable from the extension reel to the 
computer, and the boom angle sensor.  The extension reel provides the following signals that are sent 
directly to the computer via the extension reel computer cable:

•  The Boom Extension Signal is generated within the extension reel, and controlled by the reel-off cable, 
as the boom is extended or retracted.  The extension reel measures the boom extension and provides a 
signal, which enables the computer to calculate the operating radius of the crane, the weight of the actual 
load, and the percent of rated capacity.

•The Two-Block Signal is transmitted from the boom head, through the reel-off cable, to the extension reel, 
and the extension reel cable to the computer.  This signal
