Battery Inspections
The FS100 has a battery that backs up the important program files for
user data in the CMOS memory.
A battery alarm is indicated when a battery is weakened to be replaced.
Also, a message "Memory battery weak" appears on the programming
pendant display.
Refer to
section 5.3 “Battery Replacement”
When the programming pendant is not used, be sure to confirm, from the
LED audit window on the FS100 front door, that the battery alarm LED of
the CPU unit (CPU-201R) is not lit up.
Also, the battery alarm status can be confirmed by “battery alarm” of a
system input.
