CL Setting range Description
[Default]
2 40 to 300 ms The inherent closing time of the MCB corresponds to the lead-time of the
close command.
[80 ms]
The close command will be issued independent of the differential frequency at
the entered time before the synchronous point.
2 This is used for special circuit breakers to put the MCB into a defined initial
state or to enable closing at all.
Yes Before every close-pulse, an open-pulse is issued for defined duration
(parameter
pulse is issued.
[No] The CB close pulse is enabled without being preceded by a CB open pulse.
2 0.10 to 9.90 s This time defines the length of the MCB open time pulse, if the automatic
switch unblocking MCB is activated.
[1.00 s]
CL Setting range Description
[Default]
2 Off The synchronization is disabled; the frequency and voltage adaptation for
synchronization is not active.
Permissive The unit acts as a synch check device. The unit will not issue speed or
voltage bias commands to achieve a synchronization, but if phase matching
synchronization conditions are matched (frequency, phase, voltage and
phase angle), the control will issue a breaker close command.
There are two different functionalities of this option depending on the setting
of parameter
n
n
Check Used for checking a synchronizer prior to commissioning.
The control actively synchronizes generator(s) by issuing speed and voltage
bias commands, but does not issue a breaker closure command for synchro‐
nizing.
[Run] Normal operating mode. The control actively synchronizes and issues breaker
closure commands.
Notes
The device will still perfom a dead busbar closure if the conditions are valid.

5718 Ä p. 207. A CB close pulse is enabled only after the open
3414 Ä p. 202 (GCB close command).
GCB close command set to "Impulse":
The GCB close command is pulsed as long as the synchronization con‐
ditions are matched.
GCB close command set to "Constant":
The GCB close command remains enabled as long as the synchroniza‐
tion conditions are matched.
