Tab. 7.6: Response values (menu 6.5)
Note:
1)
When using a coupling device CD14400 or CD25000, the menu item "Ground-fault trip > off"
is not available.
2)
Observe the maximum trip time and the restart time (t
restart
) for the installed CD-series cou-
pling device when setting the time delay t
trip
(see Tab. 8.1).
6.5.9 6.5.8
t
restart
On the
device:
t(restart)
100 ms…24 h
Time delay between fault elimination
and automatic restart of the installation;
only used when "Alarm stored > off" has
been selected.
6.5.10 6.5.9 Restart count 1…5
Number of restart attempts within 24 h;
only used when "Alarm stored > off" has
been selected.
6.5.11 6.5.10 Trip signal
RMS
Trips on the full-spectrum RMS value (f =
DC…3.8 kHz).
Fundamental
Trips on the RMS value of the fundamen-
tal.
Harmonics Trips on the RMS value of the harmonic.

Indicate range of harmonic that should
trigger the trip relay if the threshold
value has been exceeded; only active
when "Trip signal > Harmonic" has been
selected.
