Real Time Clock The PowerFlex 755 is equipped with a real-time clock with a battery backup.
This enables programming of real time in the drive, and keeping that time even if
the drives power is removed. This enables actual timestamps instead of runtime
timestamps for faults and events. It is also used in the runtime accumulation of
maintenance items such as total run time, number of times fans are running and
so forth. If a battery is installed and the time values are set, time is accumulated.
Approximate battery life is 4.5 years with drive unpowered, or lifetime if drive is
powered.
The real time clock on the drive can be set two different ways. It can either be set
from the HIM, or from Drive Executive/Drive Explorer.
