After the system start, the battery must charge continuously for 5 hours to ensure
that the Windows service runs the evaluation of the "Battery exchange needed" sta-
tus.
Recommendation: an evaluation of the battery should be performed weekly.
For the evaluation of the battery, one of the two following conditions are required:
The battery must be continuously charged for at least 5 hours (detection of "battery is
fully charged" via time condition).
The charging current has sunk to 30 mA during the charging phase (detection of "bat-
tery fully charged" via charging current. depending on ambient conditions, this case
should not occur).
In addition, the following condition must always be met:
The USV must be active due to a main power loss, this means that the device must be
powered by the battery (status bit "The UPS is active"). The battery is not evaluated
when the system is not shut down by a loss of main power, but for example, with [ALT]
+ [F4] -> [shut down].
The Windows service sets the status "Battery exchange needed" when:
The main supply has failed and
At the same time, during the "SigmatekUpsMonitor" Windows service runtime, the
battery voltage drops below 13.2 V. This guarantees that the loss of the actual 24 V
supply can still be buffered without error.
The circa last 5 seconds until the UPS deactivates the buffered supply and is no longer
detected by the Windows service, has no effect on the correct evaluation.
