Unfortunately they need to be separated due to the logic and control system.

Can line 3 is independent of the rest of the machine to allow recovery when it fails.

If it’s linked with the rest ordinarily and something like this happens then it would be dead with no simple way to recover it

You’re not wrong about lightning though as a crane technician i see lightning strikes far to often and it’s always expensive and time consuming

I wish we had a schematic.

Even when I worked for Liebherr once a circuit entered a control module it may as well be a magic box Liebherr are very protective of that information.

Cheers that is where the output is you’re great at deciphering my ramblings haha.

We’ve already gotten the machine running with a new board but out of our own curiosity we wanted to see if there was some sort of “simple” fix.

I might give this a try and go from there

Replaced already was just an exercise in curiosity.

Liebherr don’t repair them they just sell a new part.

(I used to work for them before going independent)

Yeah already done that and a second module at a cost of 17k for the two.

Was just an exercise in curiosity really since they get hit once or twice a year
