UNKNOWN FAULT CODE

hellow fellow OKK users, I got an alarm while running and can not find it in our books anywhere, it gave me PL0011 #2011 "COOLANT UNIT TROUBLED 1" I shut down and rebooted the machine the next day and so far it has run fine?? any clues are greatly appreciated because OKK would not return my phone calls

Look in your electrical manual from OKK. All PLC alarms are in there. Check the filter on your oil coolant unit. It may be getting dirty.

thanks mitsman , filters look good, our OKK rep says it is a phase detect circuit problem so our electrician bypassed it because we know our phasing is corect and that solved the problem untill we can find a replacement component. what type of control so you have? ours is a 635 V

[Mitsman]

For standard Mitsubishi controls we have here at least one of the following: 5000CII, M83, M84, M85, M86, M0, L0, M300, M3, L3, C3, M2, M2A, M500, M50,C5, C6, E60, E68, M60, M64, Magic64, M65, M66, M64S, M65S, M66S, M610, M625, M635, M635V, C70, M70A, M730, M750, M720BM.

are you saying that you have info for the 635V ? if so I would appreciate any PDF documentation, I downloaded the basic operations and programming PDF from the mits website but any "in depth" info on this machine seems hard to come by, thanks
