11.4.8 Procedure following power failure
11.4.8.1 Overcurrent shutdown
If overcurrent >8 A is present during battery operation for a duration of 16 seconds, then an overcurrent shutdown
takes place. A switch-off time of one minute is available to the system.
If power returns during this time, then the shutdown process is aborted.
Information:
Overcurrent shutdown has the highest priority.
11.4.8.2 Low battery shutdown
If the LowBatteryFlag is set during power failure, then a "low battery" shutdown is performed to prevent the battery
from fully discharging. Once the switch-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.
11.4.8.3 Standard shutdown
The standard shutdown is in effect whenever the UPS service is active; the switch-off time is 3 minutes by default.
If power returns during the switch-off time, then the shutdown procedure is aborted.
If power returns during the shutdown process, then the shutdown timer will run until the B&R Industrial PC enters
standby mode, at which point the system will be rebooted.
