Settings of the implemented configurations
Definition for the following tables:
Lines highlighted in gray mean that the associated parameters can be edited. All other settings are fixed.
Connection Modes
2-wire
Only the voltage between L1 and N is evaluated
3-wire
Only the line to line voltages U
L1-L2
, U
L2-L3
and U
L3-L1
are evaluated
4-wire (LN)
Only the phase-to-neutral voltages U
L1-N
, U
L2-N,
and U
L3-N
are evaluated
4-wire (LN+LL)
Both the phase-to-neutral voltages U
L1-N
, U
L2-N,
and U
L3-N
as well as the phase to
phase voltages U
L1-L2

Units
%Unom
Percent of the nominal voltage (nominal voltage factor)
Functional safety
Errtol 2ch
2 separated contactors with 2 separated auxiliary contacts are connected
Errtol 1ch
1 external contactor with 1 auxiliary contact is connected
Operational mode
It is possible to switch between 2 different operating modes

Auxiliary contact
Read back of the position of the actuated contactors (via positively-driven auxiliary contacts) is required for
the necessary functional safety. The following can be selected for these auxiliary contacts:
Contact n.c. (normally closed)
Auxiliary contact is normally opened (recommended implementation)
Contact n.o. (normally opened) Auxiliary contact is normally closed
Contact dis. (disabled)
Auxiliary contact is ignored (impermissible for standards that require
functional safety)
Ranges
Conformity range
Within this range, the device is configured in compliance with the selected
standards. Outside of these ranges, the device is no longer compliant with
standards and the corresponding certificates lose their validity. This status is
shown on the display by the identifier "ncnf." Settings outside of this range are
therefore within the operator's scope of responsibility and/or the acceptance
authority of the system.
