Liebherr LICCON 1 Load Moment Indicator Service Manual

The LICCON 1 is Liebherr's electronic load moment indicator. It monitors crane loading and tells the operator where the crane stands against its limits. When it throws a fault or reads wrong, the person reaching for this manual is usually a technician who needs to test the system, read the inputs and outputs, and get the readings back in order.

What this manual helps you do

• Check the functional data of the system visually with the test system.
• Trace CU-inputs and CU-outputs, including the inputs for incremental sensors.
• Adjust initial or final currents using the modification procedure.
• Transfer incremental sensor values when a sensor is replaced or reset.
• Troubleshoot faults by reading the error stack and working through the data and AWL operand sections.

Who this is for

A crane service technician or rental fleet mechanic who has to test and fault-find a LICCON 1 in the shop or in the yard. It also suits an independent repair shop that has taken in a used crane with no paperwork.

FAQ

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

A: You get one PDF file of 48 pages in English, with a text layer you can search and copy. It runs from General and Abbreviations through the test system checks, CU-inputs and outputs, Data, the AWL Disinterpreter, AWL operand specification, current modification, sensor value transfer and the error stack.

Q: Which machine does it fit?

A: It is written for the Liebherr LICCON 1 load moment indicator. The publication number is OW-16, and the title on the manual reads "LICCON 1 Test System General".

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

A: If you're testing the system, checking inputs and outputs, or chasing a fault through the error stack, you'd expect to work from this manual at the bench. It is the complete manual for the LICCON 1 test system, so you have everything in one file.

Open it next to the test system and work through the checks, inputs, outputs and error stack in order.
