Switchgroups SGR1...SGR9 can be used to link
the start or trip signal of any protection stage to
the desired outputs SS1...SS4 or TS1...TS4.
Two output operation modes, i.e. a continuously
energized or a pulse-mode output operation can
be selected for the output signals SS1...SS4 and
TS1...TS4(switches SGF5/1...8). A continu-
ously energized output remains active as long
as the protection stage controlling it is active.
When a pulse output is used, the output remains
active only as long as the preprogrammed pulse
Either the main settings or the second settings
can be selected as the actual setting values used.
Shifting between main setting and second set-
ting values can be done in three ways as fol-
lows:
1. Over the serial bus, using command V150.
2. By using any external control signal.
3. Via the push-buttons of the relay module, in
subregister 4 of register A. When the value
of subregister 4 is 0, the main settings are
used and when the value is 1, the second set-
ting values are used.
The push-buttons on the front panel, an exter-
nal control signal or a serial communication pa-
rameter can be used for resetting the operation

is present, even though the protection stage con-
trolling the output stays active.
Resetting of the output relays appears from the
table in paragraph "Resetting".
The TRIP indicator on the front panel can be
set to indicate activation of any output signal.
The operation indicator remains lit, when the
output signal resets. The switchgroup SGF6 is
used for selecting these functions.
The main and second settings can be read and
set over the serial bus, by using the S param-
eters. The push-buttons on the front panel can
be used for reading and setting only the actual
setting values used. When the second settings
are in use, the indicator of the selected setting is
flashing.
Note.
If external control signals have been used for
selecting the main setting or the second setting,
shifting between the settings cannot be done
over the serial bus or with the push-buttons on
the front panel.
