10.4.8 Procedure following power failure
Over-current shutdown
If an over-current >8 A is present during battery operation for a duration of 16 seconds, the over-
current 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.
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 "over-current" shutdown or "standard" shutdown is detected during the shutdown process,
the "low battery" shutdown is replaced by the respective process.
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 APC620 enters standby mode and will then reboot the system.
Information:
Regardless of these options, all changes to the UPS status are logged in Windows
event protocol (under "Application").
Information:
The over-current shutdown has the highest priority.
