Description
This setpoint selects the method of
optimalization of priorities
:
DISABLED
Optimalization is disabled. Priorities are given directly
by the values adjusted into the setpoints
RUN
HOURS
EQU
The priority setpoints are automatically updated
(swapped) to equalize running hours of the gen-sets
or to keep constant difference of running hours.
LD
DEMAND
SWAP
This method changes the priorities (not the setpoints
itself) of up to 3 gen-sets of different capacity to
optimalize which gen-sets are running according to
their capacities and actual load demand (if more gen-
sets are needed, please use IGS-NT-PSC firmware in
additional controller - more information about this FW
can be found on our webpages
). Note
that this priority swapping function may be used only
if

Optimalization of priorities

N
OTE
:
Setpoint Priority in gen-set controllers is not actually changed by AutoSwap
functions - the priority is changed only locally during AutoSwap function is
enabled. Note that after RHE is activated any changes in the actual priority
setpoints need to be confirmed by disabling and enabling RHE again to take
effect.
N
OTE
:
If the optimalization is enabled at least one gen-set in the group must be set as
the master for the optimalization (
= MASTER). It is possible to have
more than one master, the one with lowest CAN address will play the role of the
master and if it is switched off the next one will take the master role.
C
AUTION
!
If the controller which is set to MASTER in PriorAutoSwap function is in
, priority autoswapping will not work and no other controller will assume
MASTER role.
