SAFETY PRECAUTIONS

5. WARNINGS RELATED TO DAILY MAINTENANCE
WARNING
1. Memory backup battery replacement
Only those personnel who have received approved
safety and maintenance training may perform this work.
When replacing the batteries, be careful not to touch the
high–voltage circuits (marked
and fitted with an
insulating cover).
Touching the uncovered high–voltage circuits presents
an extremely dangerous electric shock hazard.
NOTE
The CNC uses batteries to preserve the contents of its
memory, because it must retain data such as programs,
offsets, and parameters even while external power is not
applied.
If the battery voltage drops, a low battery voltage alarm is
displayed on the machine operator’s panel or screen.
When a low battery voltage alarm is displayed, replace the
batteries within a week. Otherwise, the contents of the CNC’s
memory will be lost.
Refer to the maintenance section of the operator’s manual or
programming manual for details of the battery replacement
procedure.
