The following start/stop curve will be generated if a bow setting is used:
Fan
Output
At parameter 6581 to 6584, the output relays for fans A to D are selected. The purpose
of these relays is to issue a signal to the fan starter cabinet. The relay must be
energized for the fan to run.
Fan Start Delay
If two or more fans are requested to be started at the same time, it is possible to add a
start delay between each fan start. The reason for this is to limit the peak start current,
so all fans will not contribute with a start current at the same time. This delay is
adjusted in the parameter 6586.
