Mori MV40B Yasnac MX3 554 Alarm
I have a MV40B with MX3 controller, it goes into alarm 554 lube/oil alarm. I do know I had a pressure switch that was stuck on the spindle luber, I have fixed the problem but I cannot get the lubers to come back on while the machine is starting up. Any help or experience is greatly appreciated in maybe resetting this part of the unit, I have dissassembled all the parts and verified all is working but my contactors will not power back up, I can push in on the contactors and both lubers work. Thanks

Thank you for your reply, I will check the float switches. My manual buttons are not working as well, like the whole system is shut off for some reason? I have checked all wiring and all components individually and did have a stuck pressure switch but have fixed it, but cannot get it to power up either luber, I can press the contacts in on either contactor and they both will build pressure on the spindle as well as the ways with no issues? I almost feel as the controller is holding them out for a reason if thats possible? Thanks and any ideas are greatly appreciated

unfortunately I dont have the ladder diagram, however I was able to trace down where the coil was getting (or not getting) its voltage and found that the B stat relays where working but the Omron relay giving voltage to them appeared to be stuck, I took it apart an cleaned it and its up and running thankfully. I also ordered a extra relay to replace the one that was stuck. I cant thank you enough for your help, I really appreciate it and your suggestions.
