This alarm has been popping up every so often and has gone away before we've found the problem, and here it is in the middle of a job that is very special to my shop. This time I'd really like to solve it.
The message is EX50 Lube Pump Failure, causes singleblock action only.
The manual Hardinge sent me is evidently for the CHNC not the CHNC2 as several differences are shown inside.
First off, can someone tell me if this alarm is pertaining to the Bijur type lube assy on the side of the machine and what parameters are seen that set this alarm?
