Innovations with regard to VDE-AR-N 4105
For the 3 new parameter sets of VDE-AR-N 4105 (3.3.3-5), the following applies for the commissioning:
When commissioning, make sure that only one coupling switch (on R1) is used. 3.3.5. for inverters is an
exception here - 2 coupling switches (on R1 and R2) must still be used.
Furthermore, the feedback contact(s) must be connected to the digital inputs I1(2)-
┴
provided for this
purpose. Finally, parameter 3.099 determines whether the feedback contact(s) are normally closed (n.c.) or
normally open (n.o.).
An Error C (Contact) appears on the display if this has not been taken into account. NA003 must not switch
on the output relays R1(2) for VDE-AR-N 4105 during error C as long as the feedback contacts are not
correctly connected and parameterized.
Contact Error-Reset:
If U
N
3x400V AC is correctly connected, a reset can only be carried out by pressing the Esc (level 1.010) or Ent
(level 1.050) key. The contact error is then cleared and the output relays R1/2) energize after the switch-on
time has elapsed.
An existing contact error can also be reported to the generation system via R3.
In this context, we would like to refer to Chapter 3.9 Test function (Determination of the tripping time of the
coupling switch).
Password protection:
With regard to VDE-AR-N 4105, the devices are supplied with fixed password protection. The password is
"4105". The commissioning engineer is requested to change the password immediately for safety reasons
(see 5.2.5).
