With the setting INs,Ib,Ic,Vx=Ia, however, the measuring input Ia is used as sensitive current input In
sensitive and the measuring input Vx as LoPo/LPS current input Ia.
With the setting Ia, INs, Ic, Vx, however, the measuring input Ib is used as sensitive current input In
sensitive and the current Ib is calculated. It is thus possible to detect any voltage via the voltage input Vx
also in this connection variant. Siemens recommends supplying the Ι
Ns
input up to 2.5 Ι
N
at most.
At address 350 Bat. Monitor you can activate the voltage monitoring of the external battery.
The flexible protection functions can be configured via the FLEXIBLE FUNC. parameter. You can create up
to 20 functions by setting a checkmark in front of the desired function. When the checkmark of a function is
removed, all settings and configurations made earlier are lost. After reselecting the function, all settings and
configurations are in default setting. The flexible function can be configured in DIGSI at “Settings”, “Additional
Functions” and “Settings”. Configuration is done, as usual, under “Settings” and “Configuration”.
If you want to use the 3-/1-pole operation function, set address 374 Triple Single to Enabled.
