Inverted Input (system start is blocked when the
MCB fail occurs)
New Sys S/S function which should be used to
start and stopped the gen-set group instead of
LBO Sys start/stop
LBO Sys start/stop
Indication of MCB fail and request for start block
9.2 General Information
N
OTE
:
In the following text, “CB” abbreviation is used for MCB or MGCB respectively.
9.2.1 Related binary inputs:

CB
FDB
– CB feedback binary input.

CB
FDB NEG
– negative CB feedback binary input. Used for increasing the reliability of CB
status evaluated by the controller. In case that it is not configured, negative value of CB fdb is
calculated internally within the controller.

CB
DISABLE
– this input is used for disabling issuing of CB closing command (if CB is closed
and this input is activated CB is opened immediately).
9.2.2 Related binary outputs:

CB
CLOSE
/
OPEN
– output for circuit breaker. Equals to 1 during the time when CB is requested
to be closed.

CB ON
COIL
– output for closing coil of the CB. 2s pulse (5s if synchronising is not provided by
the particuilar CB) is used for closing the CB.

CB OFF
COIL
– output for opening coil of the CB. 2s pulse (5s if synchronising is not provided
by the particuilar CB) is used for opening the CB.

CB UV
COIL
– output for undervoltage coil of the CB. Permanently active, 2s negative pulse
(5s if synchronising is not provided by the particuilar CB) is used for CB opening request.

CB
STATUS
– output indicating CB status as evaluated by the controller. This signal is used for
lighting

LEDs on the panel, switching the regulations, CB fail evaluation, etc.
N
OTE
:
All pulse outputs for CB in following diagrams may be long 5s if the CB is not used for synchronization
in that particular instance.
