9.4.8 Procedure following power failure
9.4.8.1 Overcurrent Shutdown
If an overcurrent > 8 A is present during battery operation for a duration of 16 seconds, the overcurrent shutdown
is executed. A turn-off time of one minute is available to the system.
If the supply is regenerated during this time, then the shut down process is aborted.
Information:
The overcurrent shutdown has the highest priority.
9.4.8.2 Low Battery Shutdown
If the LowBatteryFlag is set during power failure, then the "Low Battery" shutdown is executed, preventing the
battery from fully discharging. Once the turn-off time expires (3 minutes by default), the UPS shuts down.
If an "overcurrent" shutdown or "standard" shutdown is detected during the shutdown process, the "low battery"
shutdown is replaced by the respective process.
9.4.8.3 Standard Shutdown
The standard shutdown is effective when the UPS service is active, the turn-off time is 3 minutes by default.
If the supply voltage returns during the turn-off time, then the shutdown procedure will be stopped.
If the supply voltage returns during the shutdown process, then the shutdown timer will run until the B&R industrial
PC enters standby mode and will then reboot the system.
