PAT iSCOUT Load Moment Indicator Service Manual

An LMI keeps watch on crane loading by reading boom angle, boom length, pressure, slew position and load, then showing the operator what the crane is doing against its limits. When a sensor drifts or the console goes blank, the crane is parked and the rental clock keeps running. The service manual is what a technician picks up to find the fault and fix it in the yard.

What this manual helps you do

• Troubleshoot a blank screen using the sections on no console display, A2B problems and CAN-bus communication.
• Diagnose a sensor fault from the display, working through angle sensing, length sensing, pressure sensing, slewing sensing and load sensing.
• Look up error codes and fault diagnosis entries so you know what the system is reporting.
• Follow the sensor calibration procedure after a sensor is replaced or has drifted.
• Trace wiring and connections with the drawings, and work through the moisture troubleshooting section when water is the suspect.

Who this is for

Crane service technicians and rental fleet mechanics who repair LMI systems in-house on Grove RT and TM cranes. Independent repair shops and dealer technicians will also find the fault-finding steps useful when a machine arrives without paperwork.

FAQ

Q: What do I receive and how is it organised?

A: You get 1 PDF file of 61 pages in English, with a text layer you can search and copy. It runs from general information, warnings and system description through troubleshooting, drawings, sensor calibration and error codes.

Q: Which system does it fit?

A: It is the PAT iSCOUT service manual, publication number 50 650 69 0101e, titled "iFLEX2 iSCOUT Service Manual for Grove RT/TM", so it covers both iSCOUT and iFLEX2. The cover may carry the older Hirschmann name, so don't be thrown by the logo.

Q: How does it fit the job I'm doing?

A: If you're chasing a fault, the "What's wrong?" sections point you to the right sensor or circuit, and the error code list tells you what the display is flagging. Then you can calibrate and test.

Keep it on the shop computer, search a fault code, and get the crane back on the job.
