PAT PRS145 Load Moment Indicator Service Manual

The PAT PRS145 is a load moment indicator. It watches crane loading and warns the operator as the machine nears its limit. When the system acts up, throws a fault, or needs a part swapped, the service manual is what a technician picks up to sort it out in the shop. The cover may show the older brand name Hirschmann, so don't let the logo throw you.

What this manual helps you do

• Trace the connections between the console and the central unit when the display or readings drop out.
• Follow the troubleshooting flow charts to narrow down a fault step by step.
• Look up error codes and see what each one points to.
• Adjust the basic hardware settings on the central unit using the documented procedures.
• Replace components and check the work against the drawings and definitions.

Who this is for

A crane service technician or rental fleet mechanic who keeps LMI systems running. Also an independent repair shop that gets a PRS145 on a machine with no paperwork and has to fix it in-house.
