Changing the Relay Assignment (Relay Manager; Standard /
Option R
)
Change relay-
allocation? YES
Change relay assignment?
YES/NO
This parameter permits the user to change how the relay outputs are configured.
Refer to the list of parameters.
YES
..............The relay assignments can be configured and the user may define the
relay functionality and assignments. The subsequent screens are dis-
played.
NO
................The relays are configured with the factory default settings. The sub-
sequent screens are not displayed.
NOTE
All relay outputs are configured the same. The following is an example showing relays 1 through 3.
Depending on the model purchased, the unit may have up to 7 configurable relays.
Option R
enables
to use 5 additional relays
Example:
Relay 1 to 3
Funct. relay 123
(R=releases) RRR
Function of the relays 1, 2 and 3
E/R
The individual relays may be configured as either E=Energizes (Normally Open
contacts) or R=Releases (Normally Closed contacts).
E
...................The relay is configured as normally open (N.O.) contacts. The relay
will energize only if the assigned monitoring function has tripped.
R
...................The relay is configured as normally closed (N.C.) contacts. The relay
is always energized and will only de-energize (release) if the as-
signed monitoring function has tripped.
NOTE
Relay 1 is configured as R (release/N.C.) and cannot be modified.
NOTE
Units with
Option YC
do not enable to configure the function of relay 3. The synch-check function is
always assigned to relay 3 (or relay 8 for units with
Option YC
and
Option R
). Relay 3 (8) is fixed to
N.O. For reasons of redundancy, the synch-check function may also be assigned to relay 2 with the
following parameter starting with SW version 3.1450.
2. Synch.Check
relay 2 OFF
only available for
Option YC
starting with SW version 3.1450
2
nd
Synch-check triggering assigned to relay 2
ON/OFF
This parameter permits the user to assign the synch-check function to relay 2 as
well for reasons of redundancy.
ON
................The synch-check function is assigned to relay 3 (8)
and
relay 2. No
monitoring function may be assigned to relay 2.
OFF
..............The synch-check function is only assigned to relay 3 (8). Relay 2
may be used for other monitoring functions.
CAUTION
If above parameter is configured to "ON" and a monitoring function is assigned to relay 2, relay 2 will
not react if this monitoring function is triggered.
