PAT Modular PDC Load Moment Indicator Service Manual (PDC V1.3a1)

An electronic load moment indicator (LMI) monitors crane loading, and the PAT Modular PDC is the unit that does that job on the machine. When it throws a fault or reads wrong, the crane is down until someone sorts it out. This service manual is for the person doing that work in-house: checking the system, finding the fault and getting the crane back on the job.

What this manual helps you do

• Trace faults through the system description to find where a problem starts
• Check sensors and run calibration steps so the readings match the crane
• Diagnose error codes and work out what each fault points to
• Verify wiring and connections when a signal drops out or reads erratically
• Replace components and set the system up again afterward

Who this is for

Crane service technicians and rental fleet mechanics who repair LMI systems on their own machines. It also suits independent repair shops and dealer technicians who get a crane in with a PAT PDC unit and need workshop-level information to fix it.
