DISABLED, RUN HOURS EQU, LD DEMAND SWAP [-]
This setpoint selects the method of optimalization of priorities:
Optimalization is disabled. Priorities are given directly by the
values adjusted into the setpoints Priority.
The priority setpoints are automatically updated (swapped) to
equalize running hours of the gen-sets or to keep constant
difference of running hours.
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 www.comap.cz).
Note that this priority swapping function may be used only if
Pwr mgmt mode is set to ABS (kW).
NOTE:
See the chapter Optimalization of priorities for more details.
NOTE:
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.
NOTE:
If the optimalization is enabled at least one gen-set in the group must be set as
the master for the optimalization (Priority ctrl = 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.
CAUTION!
If the controller which is set to MASTER in PriorAutoSwap function is in Emerg.
manual, priority autoswapping will not work and no other controller will assume
MASTER role.
Setpoint: Priority ctrl
This setpoint is used to select the role of this particular controller in the
optimalization of priorities.
