Looking in the fault stack, 1-400-711 showing in the fault stack and BrF on the hoist drive this was the first fault. The second fault was 1-230-007 load sensor wiring problem.
It would always have the 400 code then the 230 code. Need to always look past the first fault code
Checked and all drives were shutting off, not just the hoist drive. Tomas says if all drives shut off, its not the brake but rather the brake fault is a result of another failure.
Near the upper limit, the 0 load was showing 230 pions. In the manual, the crane wants between 1150-1350 pions. As a result, the crane would fault and shut off all drives and the fault 1-400-711 was a result of shutting off the brake contactor and the 230 code from the processor shutting down the drives.
The teach-in portion of the manual tells the tech to lower the block all the way to the ground raise until the hoist cable is in the middle of the drum. This load cell was only reading 364 pions.
Replaced the load cell and redid the teach-in. The crane was only reading 936 pions at 0 load. Although lower than what the manual specified, it is within the operating range of the crane.
