PAT DS 85 Load Moment Indicator Service Manual

The PAT DS 85 is a load moment indicator, the system that monitors crane loading and warns the operator as the crane approaches its limits. When the readout goes dark, a sensor drifts or the anti-two block warning acts up, the crane sits idle. A service manual is what a fleet mechanic or crane service technician picks up to find the fault and fix it in-house.

What this manual helps you do

• Diagnose a blank screen by working through the no console display procedure.
• Troubleshoot angle, length, pressure and load sensing faults one sensor at a time.
• Set up and calibrate the anti-two block system, and trace an A2B problem.
• Check CAN-bus communication when the display and sensors stop talking.
• Verify error codes and use the service screen for sensor calibration.

Who this is for

Crane service technicians and rental fleet mechanics who repair LMI systems themselves. It also suits independent repair shops that get a DS 85 in with no paperwork and need a reference to work from.
