Setpoint changes behaviour of binary output Neutral CB C/O which is used
for Neutral contactor control.
EACH:
- When GCB is opened (after start, before stop):
o Neutral contactor closes when Generator voltage is higher than
85% of Nominal voltage.
o Neutral contactor opens when Generator voltage is lower than
50% of Nominal voltage.
- When multiple gen-sets are connected to the bus and MCB is opened
(island running group) the Neutral contactor is closed on the running
gen-set with the lowest Contr. address only. When a lower controller
address gen-set is connected to the bus, the Neutral contactor
connection changes.
- Neutral contactor is opened when gen-sets are running in parallel to the
mains.
COMMON:
- When MCB is opened Neutral contactor closes when at least one
Generator voltage from the group (at least one phase) is higher than
86% of Nominal voltage.
- When MCB is opened, the Neutral contactor opens when all phases of
all gen-set voltages are lower than 50% of Nominal voltage.
- When MCB is closed, the Neutral contactor opens.
NOTE:
Configure BO: Neutral CB C/O and BI: NeutralCB fdb prior to Neutral
contactor function is used.
User-defined name, used for controller identification at remote connections.
The name can be max. 15 characters long and must be entered using
LiteEdit.
NOTE:
The setpoint can't be changed from the front panel of the controller.
