NOTE
If the mains monitoring (frequency and voltage) is disabled, decoupling from the mains is not per-
formed.
Parameter 133
Mains decoupling
via ------
[GCP-32]
Decoupling from the mains via ... GCB; GCBMCB; MCB; MCBGCB
GCB ............. If a mains failure (Parameter 179 through Parameter 193) occurs the
GCB will be opened. A mains failure is detected by means of the
mains voltage (terminals 50/51/52).
GCBMCB If a mains failure (Parameter 179 through Parameter 193) occurs the
"Co
mmand: Open GCB " relay (terminals 41/42) will be energized.
A mains failure is detected by means of the mains voltage (terminals
50/51/52). If the GCP does not receive the reply that the GCB has
opened (terminal 4 energizes) prior to the time configured in Para-
m
eter 134 expiring, an F1 alarm will be issued and the relay assigned
relay manager function 76 will be energized. The "Command: Open
GCB " relay (terminals 41/42) will de-energize and the "Command:
open MCB" relay (terminals 39/40) will energize.
Issuing of F1 class alarm
MCB ............. If a mains failure (Parameter 179 through Parameter 193) occurs the
MCB will be opened. A mains failure is detected by means of the
mains voltage (terminals 50/51/52).
MCBGCB If a mains failure (Parameter 179 through Parameter 193) occurs the
"Co
mmand: Open MCB " relay (terminals 39/40) will be energized.
A mains failure is detected by means of the mains voltage (terminals
50/51/52). If the GCP does not receive the reply that the MCB has
opened (terminal 54 energizes) prior to the time configured in Para-
m
eter 134 expiring, an F1 alarm will be issued and the relay assigned
relay manager function 77 will be energized. The "Command: Open
MCB " relay (terminals 39/40) will de-energize and the "Command:
open GCB" relay (terminals 41/42) will energize.
Issuing of F1 class alarm
Parameter 134
Mains decoupling
-> after 0.00s
only accessible via LeoPC1
Mains decoupling after 0.10 to 5.00 s
The maximum amount of time that the mains decoupling should be completed in.
WARNING
It is possible for the MCB to close after the mains settling time (Parameter 194) expires, causing the
busbar to energize, while maintenance is being performed on the busbar if Parameter 135 is configured
as "YES". Closing of the MCB can be disabled by
configuring Parameter 1355 as "NO" or by blocking
the
MCB through other methods.
Parameter 135
Switch MCB in
STOP mode NO
[GCP-32]
Close MCB in STOP operation mode YES/NO
YES .............. The MCB will be closed by the GCP when the STOP mode is
enabled. The breaker will not close unless the "Enable MCB" dis-
crete input (terminal 54) is energized as well.
NO ................ The GCP will not change the state of the MCB when the STOP mode
is enabled The breaker will remain open or closed depending upon its
state when the operation mode is changed to STOP.
