Home the A-axis or orient the axis before starting the removal procedure.
1. Remove the pallet from the receiver.
2. Remove the Z-axis way cover from the front (closest to the load station) of the rotary table.
3. Loosen the single bolt in the switch plate assembly.
4. Pull the switch plate assembly away from the center of the receiver.
5. Remove the one bolt at the bottom of the rotating union. The rotary union is now loose and can be
removed; pull it straight down.
6. Remove the bolts securing the receiver to the base.
The receiver is now ready to be removed from the machine.
7. Use lifting equipment to remove the receiver. The receiver plate has 1/2-13 tapped holes in it so
that lifting eyes can be installed, or use straps to grip the top of the receiver. It is possible to
remove the receiver assembly through the operator door.
8. Carefully lift the receiver assembly up; just free of the base.
9. Note the size and position of any shims. These will need to be reinstalled in the same position in
order to keep proper alignment.
10. Completely remove the receiver form the base and out of the machine.

EC-400 - Pallet Changer - Receiver - Installation
1. Use straps to lift the receiver assembly. Make sure all of the surfaces are clean.
2. Replace shims on the base, if necessary.
3. Position the assembly, orienting the clamp plate, over the base and lower into place.
4. Install the rotary union at the bottom of the receiver shaft.
5. Align the switch plate assembly and tighten the mounting screw.
6. To test the pallet press “Jog A” to lift the platter and “Reset” to lower it. There are two switch
assemblies that may need to be adjusted. The switches are on the out side edge or the switch
plate (one for rotary platter clamp, one for rotary table unclamp). Adjust the set screw trigger for
each switch as necessary. The switches have an LED on them that will show the reading of the
switch.
7. Install a pallet on to the receiver.
10.Set up a magnetic base and indicator, placing the tip of the indicator into the hole in the pallet.
Jog the rotary axis and check for platter alignment. The platter must be clamped before taking
readings. The concentricity of the pallet should be .002 T.I.R. The receiver base can be positioned
by tapping the base into alignment.
12. Verify concentricity, if necessary, loosen the bolts and repeat the previous step.
Set up a magnetic base and indicator, placing the tip on the pallet. Jog the X-axis and check for
parallelism. Repeat this for the Z-axis. If the pallet is out of alignment, shims will need to be
placed under the receiver assembly. Flatness is not to exceed .0005/10”.
13.Command a pallet change and repeat the previous step for the second pallet.
14.Replace the Z-axis way cover and secure with the screws.
8.
9. Tighten the bolts which secure the receiver to the base.
