The operator starts crane and all functions work except hoist. When he tries to hoist drive throws TJF Fault.
The voltage on the generator is at 500 V had him turn it down to 480V restart the crane and it all works fine
Tower Crane Mast info on how to understand the names
One number the memo does not cover is the 2 at the end of your mast name.

The 2 just means that it is the most recent revision (non structural) to make it compliant with different safety standards. In our case it would be OSHA.
Trolley would not work on Igo T85A
Hoist and slew would work, but no trolley. Obf was displayed on trolley drive. Found trolley discharge resistor was damaged and broken. Ultimately, was an input power problem that damaged trolley resistor.
Igo T85A Horn Honks when trying to Telescope up
When trying to telescope up, horn would honk. Would go down, but not up. Went through erection aid and all looked good. Needed to readjust brake microswitch on telescoping drum.
Adjust microswitch by loosening locking nut and running down adjustment screw until “H” light comes on in CAN Open module (U213X). Back off screw, just until the light goes off.

Trolley stopped working on Potain T85A (27148)
Customer called and said stopped mid-pick while trolleying. Customer was able to hoist and swing, but no trolley. Lowered load and cleared the hook. Drive showed FST.
Went to Erection Screen and all sensors and switches were open. The thought was that we lost +24V from transformer. Customer went to get a meter, but didn’t work. Got a 2nd meter and turned crane back on. Erection Aid read correctly. Trolley drive was flickering between FST and RDY. Disconnected G33, and drive went to RDY. Power cycled the crane and all works at this time.
