Haas CNC Alarm 950 (Mill) APC-ILLEGAL SWITCH CONDITION, LIFT FRAME
Alarm Description, Cause & Remedy
The pallet changer lift frame switches indicate that the pallet changer lift frame is up and down at the same time. Verify an adequate supply of air pressure and air volume. Check the adjustment of the lift frame position switches and for debris on the switches. Check switch electrical connections and wiring. This may be a false alarm if the pallet changer was out of position by 90° (+/- 20) when a pallet change was in progress. After correcting the cause, press Tool Changer Restore to enter pallet changer recovery, recover the pallet changer, and then continue operation.
