Call Mori seiki, or Ellison depends on where you are in Canada. You most likely have the early ATC if you are getting that alarm. Ask for the MV40 ATC recovery for the early machines. That one will most likely have the rack and pinion hydraulic atc. You will need to recover the racks to home position, then clear a machine parameter. The later ones are much easier. They use a 3 phase motor in a cam-gearbox. Basicaly, if you have a hydraulic pump (NOT SPINDLE COOLER), its an early one. No hydraulic unit-later style.
