Kouwa
Kouwa Chiller display only shows ---- and A200
Mazak 6800 HMC uses Model KMV-150-M14-C. Had a 30 amp trip shut down machine. Traced to low oil in the in the Hysol (Left side oil fill port). Still tripped. The CM motor starter 4th from left was dirty with carbon. We changed it out. Still trips. We ohm'ed out the motor. Seemed good. Thinking what the motor is spinning had frozen up but the e stop won't go away and the chiller never starts. I get the 4 dashes at boot up and I can push the parameter button to see A200. Nothing else shows on the display, no alarms.
