Gen-set #1 means that the CAN address of the controller is set to 1. The relevant setpoint is adjusted
by
Comms settings: Contr. address .
By choosing the setpoint Pwr management: Priority = 1, the gen-set #4 is running all the time in the
example shown on the figure above (AUT mode selected, Pwr management enabled and LBI Sys
start/stop activated).
The priority can be also adjusted by a set of logical binary inputs Priority sw A , Priority sw B , Priority
sw C and Priority sw D . If at least one of these inputs is closed, the priority adjusted by the setpoint as
mentioned above is overridden by the priority given by the combination (binary code) of the Priority
SW inputs.

The inputs are intended for adjusting the priority by a rotary switch.
The force value function can be used to force priority 0 into the setpoint Pwr management: Priority .
Priority 0 is the "highest" one, which means the gen-set will be running all the time while the power
management is switched on.
If more than one gen-set have the same priority, they will act as "one big" gen-set. There are methods
of automatic optimization of the priorities to achieve specific behavior of the group such as equalizing
engine hours of the gen-sets or selection of optimal gen-sets to run according to their size and current
load demand.
7.6.3 Automatic priority swapping
As stated in the chapter Priorities, the operator is able to select the order of gen-set starting. There is
also the option of automatic priority selection. The controllers are sharing data concerning the running
hours and all important information relevant to the actual load. Thanks to the Automatic priority
swapping function the controllers choose the gen-set(s) to be running with consideration of their
running hours and the actual load. The
Running hours equalization (RHE) function keeps a constant
maximal difference of gen-
sets’ running hours. The
Load demand swap (LDS) function keeps running
only the gen-sets with suitable nominal power to avoid inefficient fuel consumption or gen-set
overload.
At least one gen-set in the group must be set as the master for priority optimization
(
Pwr Management: 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.
Important setpoint: Pwr management: #PriorAutoSwap
The Automatic priority swapping function does not change the setpoint Pwr management: Priority .
The function sets the order of gen-sets by
virtual values “engine priority”.
