8.2 (2.4.1.2) CT monitoring
Activate or deactivate the CT monitoring.
If CT monitoring is active, an alarm is signalled as soon as a fault occurs on a current trans-
former of an activated channel (short circuit or interruption).
CT monitoring is activated
•on
(the current transformers are monitored).
CT monitoring is deactivated
•off
(the current transformers are not monitored).
8.2 (2.4.1.3) I Response value
ΔL
Set the response value for I (main alarm for insulation fault location) between 200 μA

and 10 mA. The response value must be below the set locating current
The permissible response value and the response sensitivity depend on
the connected EDS (EDS440x or EDS441x).

8.2 2.4.2.1.1 TEST
The functional test of the relay can be activated or deactivated. This only applies to the
manual test and not to the cyclic device self test.
The manual test checks the switching function of the relay.
•on
•off The manual test does not check the switching function of the relay.
8.2 2.4.2.1.2 Operating mode
The relay operating mode can be adapted to the application.
Normally closed- N/C operation contacts11-12-14 / 21-22-24 (in
•N/C
fault-free condition, the alarm relay is energised).
Normally opened - N/O operation contacts 11-12-14 / 21-22-24 (in
•N/O
fault-free condition, the alarm relay is de-energised).
