The fan stages are loaded or unloaded one after the other with the
Direct
switching mode. The fans are also
loaded one after the other with the
KKGG
switching mode. This results in the first half of the outputs loading the
fans at low speed (star operation). The second half of the outputs switches the fans to the high speed (delta
operation). When shifting down the capacity stages, both fan outputs (star and delta outputs) are unloaded
simultaneously. The low speed is loaded again after a configurable time delay.
The following table shows the control of the fan outputs using the example of a system with two fans and four
fan stages:
