Output A and output B must be adjusted to the same relay to avoid alarms when the set point
is reached.
When a relay has been selected for this function, it cannot be used for other functions.
Start/stop scenario
This diagram shows a (simplified) scenario where three DGs are started and stopped depending on the load-
dependent start/stop relays.
The scenario shows that genset 2 starts when genset 1 reaches 80 %. The next genset to start is DG3, and
the three sets load share at 53 %.
When the load of all three gensets drops to the stop limit, which is 20 %, the load-dependent stop relay acti-
vates and a genset (genset 3 in this example) can be stopped. The load continues to drop, and at 20 % load,
the next genset to stop is genset 2.
