Pallet Changer Recovery (EC-300, EC-400, MDC)
EC-300 or MDC
If the pallet change is interrupted another M50 must be run; use M50P1 or M50P2. If this puts the wrong pallet into
the mill, then an additional M50 must be run.
EC-400
The control has a pallet changer recovery mode to assist the operator if the pallet changer fails to complete a pallet
change. To enter the pallet changer recovery mode press the Recover button and then press the specific function
key (F2) for pallet changer recovery mode. Note that is the pallet is in the proper position, the pallet changer
recover function is not available.
The most convenient way to recover from a failed pallet change attempt is to press "Y" and follow the on-screen
help text. A message will prompt the operator to command an individual step of the pallet change sequence. More
than one step may need to be completed, as each step is done, press "Y" for the next step. The control will exit
the recovery screen once the pallet changer has recovered.
Pallet Replacement (EC-400)
The pallets can only be loaded into the mill through the load station. Note the orientation of the pallet; the pallet
can only be loaded one way. A cut-out is machined into the pallet to insure the proper orientation of the pallet.
1. Orient the pallet 90 degrees from home in either direction.

2. Attach a suitable lifting device to the top of the fixture(s) or use eye bolts screwed into the pallet holes.
3. Lift the pallet approximately .25” (6.35mm) to position it above the load station pins, but below the load station
lock plate. Pull the pallet towards you until it has cleared the load station.
Pallet Storage (EC-400)
When removing the pallet, be sure to set it on a soft surface such as a wooden pallet. The bottom side of the pallet
has machined surfaces that must be protected.
