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.

Info from Potain about GREAT HEIGHTS package on hoist

Dusty,

Full hoist rope length including rope to rig the jib and maintain 3 wraps is approximately 310-320m. At 30m of HUH, the crane would need approx 220m of rope in total to work in 4 part. You might, therefore, remove about 100m of rope if you discover that the rope is not reeving properly at the lesser operating mast and HUH height.

New Memory Card in Slew Drive (ACS880) T85A

Installed a new memory stick in the swing drive on Igo T85A. Had to go to menu 74 and then to 11 to set the Supply Voltage to get started.

Then had to restart the drive and it went through a motor ID and run ID test. Once complete, had to restart the drive again and it worked fine.  The drive said it was ready to work, but was unresponsive.  Make sure to restart again.
