2. Allow system to warm up for approximately 45 minutes to
one hour, (and when the ready light is on).
3. To set Automatic Compensator circuit on, the following
procedure is to be followed:
A. Set X Axis:
1. Push X axis drive to the "Left" until the limit
switch stop motion.
2. Put on X auto-compensator switch.
3. Push X drive switch to "Right" for approximately
1" (approximately 20 seconds) and immediately reverse back to the
"Left" limit.
4. Switch off X axis auto-compensator switch when table
is still coasting close or at the limit of travel (Left).

1. Push Y axis drive to the "In" until the limit
switch stop motion.
2. Put on Y auto-compensator switch.
3. Push Y drive switch to "Out" for approximately
1" (approximately 20 seconds) and immediates reverse back to the
"In" limit.
4. Switch off Y axis auto-compensator switch when table
is still coasting close or at the limit or travel (In).
4. System is now ready for use.

6. Check repeatability
a) Place grid on platen
b) Apply vacuum
c. Set machine to center of travel with index
mark of grid at the center
d) Zero X and Y counters
e) Traverse to one edge 2 1/8" from center and go
around table as indicated. All paths 2 1/8" from
center.
f) Return to center index mark.
g) Read counters - both X and Y should read zero +
8 counts.
