Standard /
Relay
1
Terminal 9/10
Output relay (type: make contact, NO)
The "relay manager" controls this relay.
NOTE
The "ready for operation" function is always assigned to relay 1. However, other protective functions
may also be assigned to relay 1 additionally. Relay 1 is always configured as Normally Closed (break
contact) and will de-energize if the unit is not ready for operation.
Relay 2, 3
Terminal 11 through 16
Output relay (type: change-over contact)
The "relay manager" controls this relay. If the
Option YC
is installed, the
synch-check function is assigned to this relay.
Option R
Relay 4 to 7
Terminal 19 through 30
Output relay (type: change-over contact)
The "relay manager" controls this relay.
Option R
Relay 8
Terminal 31/32
Output relay (type: make contact, NO)
The "relay manager" controls this relay. If
Option R
is available in addition
to
Option YC
, the synch-check function is assigned to this relay.
NOTE
For units with
Option YC
, the synch-check function is assigned to relay 3 or relay 8 (
Option YC
and
Op-
tion R
). Therefore, relay 3/8 cannot be configured with the relay manager. Starting with SW version
3.1450 it is also possible to assign the synch-check function to relay 2 as well. In this case, relay 2
cannot be configured with the relay manager as well.
