The BAT-1 shut off module has two outputs of relays switching when shut off
impulses from energy storage No. 1 and no. 2 are sent. Use of latching relays makes them
independent of any power supply after operation of the protection device. The signal can
be reset after auxiliary voltage or current transformer power reappears.
If the optional test module is used, the shut off circuits are switched from external
circuits to the external test module checking correct operation of energy storage during the
test.
