Measures In The Event Of Conspicuous Current Sensor Values; Check Battery Charger; Check The Battery Modules; Checking The Replacement Power Network - Varta element backup 6 Operating Manual

13.6.2

Measures in the event of conspicuous current sensor values:

If, despite the charge, the current sensor value of one or several phases is 0, check the connection between the
energy storage system and the current sensor.
•
If necessary, replace the connection line.
•
Check whether the folding ferrites are correctly closed and that the cores are not damaged.

Checking the replacement power network

1. Connect the intended consumers to the replacement power network.
2. Switch off the store fuse (F1 in the connection diagram).
•
The store should automatically go into backup mode.
3. Interrupt the connection to the consumers for a few seconds.
4. Check whether the replacement power network was developed and the consumers are in operation.
Note: Remember that some consumers change operating mode only after a few minutes. Test the replacement
power network over a sufficiently long time.
5. Check in the web interface whether error messages are displayed.
Fault remedy: Possibly inrush current too great. Reduce the consumers and carry out the check again.
Fault remedy: Possibly continuous load too great. Reduce the consumers and carry out the check again.
