Description
The relay "command: GCB open"
will be de-energized to open the
GCB and will be energized again
after the discrete input "Reply
GCB" is energized to signal the
control that the GCB is open.
Not used A GCB open relay is not used and
relay R7 (Command: open GCB) is
freely programmable. In this case,
parameter
╚═▷ 3414 must be
configured to "Steady" to open the
breaker.
Notes
This parameter only applies to
application mode
A02 A03 A04 .
3414 GCB close command 2 Impulse The relay "Command: GCB close"
issues an add-on pulse. If the
relay is configured in this manner
a holding coil and sealing contacts
must be installed externally to the
control unit. The DI "Reply GCB" is
used to identify closed contacts.
[Steady] The relay "Command: close GCB"
may be wired directly into the
holding circuit for the power
circuit breaker. If this method is
utilized it is recommended that
isolation relays are used.
After the connect pulse has been
issued and the reply of the power
circuit breaker has been received,
the relay "Command: close GCB"
remains energized. If a class C
alarm or higher occurs or a GCB
open command is issued, this
relay de-energizes.
Notes

"Command: GCB open" energizes

the frequency in a way, that the
frequency of the source
(generator) is marginal greater
than the target (busbar). When
