Check fuse. With the power cord removed, use a thin straight-blade
screwdriver to remove the cover of the electrical input module. Slide out
the fuse holder and check the fuse. If necessary, replace it. Replace the
input module cover by snapping it back into place, and reconnect the
power cord.
Incorrect Operation
If system positioning does not seem to be repeatable, the problem could be
with the machine tool or with the readout system.

Check the machine tool. Check that the table is not locked. Ensure that
the knee, ram, head bolts, turret-to-column bolts, and head-to-knuckle
bolts are properly secured. Check the gib adjustments. Tram the head.
Check spindle run-out.
•
Check linear encoders.
Check each encoder and reading head for proper
installation. Ensure that the mounting brackets are secure.

CAUTION
Replace fuses only with the specified type. Using incorrect fuses
can present a safety hazard. The readout may also be
permanently damaged. Refer to the Readout Specification chart
on page 60 for the correct fuse.
