(Overhead Time)
Battery Backup Time At 25
°C, the battery life (maximum service life) for batteries is five years
whether or not power is supplied to the CPU Unit while the battery is installed.
This is the same as for CJ1G-CPU@@H CPU Units. The following table shows
the approximate minimum lifetimes and typical lifetimes for the backup battery
(total time with power not supplied).
Note The minimum lifetime is the memory backup time at an ambient temperature
of 55
°C. The typical lifetime is the memory backup time at an ambient temper-
ature of 25
°C.
EXEC Running Green Not lit The system is stopped for one of the following reasons:
• The Loop Control Board is initializing.
• A hardware failure occurred in the Loop Control Board.
• Power is not being supplied from the Power Supply Unit.
• A Loop Control Board WDT error occurred.
• The Loop Control Board is not running.
• Data is being written to flash memory.
