I tried several things and could not get the carousel back so I pressed E-stop and manually pushed the carousel back into place. Powered up the machine using the POWER UP/ RESTART button and when the carousel went into action it was slow and not performing like normal. Then the machine went into alarm 175.
175 GROUND FAULT DETECTED - A ground fault condition was detected in the 115V AC supply. This can be caused by a short to ground in any of the servo motors, the tool change motors, the fans, or the oil pump.
Anyone one else experience something like this? I took the cover off of the carousel motor compartment and nothing looked wrong or burnt.
Is this a HFO service man call issue?
Any input or comments???
Thanks
