3.5 Computer Unit Overview

The Computer Unit is the center of the System. It reads the sensors, controls computations and
disconnect functions, and communicates with the display console/internal bar graph.
The computer unit connects to the crane wiring harness via 60-way bulkhead connector. There are no
wiring connections or screw terminals within the unit.

The computer and the two hydraulic pressure sensors contained inside are calibrated during production.
These sensors are unable to be replaced in the field.

3.5.1 Computer Unit Layout

3.5.2 Internal Status Indicators

The computer unit contains a row of LED indicators for checking computer operation. During normal
operation, all LEDs will be illuminated with the COMM indicator blinking. If not, please contact Technical
Support for assistance. Use the following chart and Figure 3.2 for LED location.
