Load assignment (flexible step switch only)
With the flexible step switch, assign the load to the aggregates so that as few
aggregates as possible are operating and optimum control is achieved under
partial load conditions.
To this end, the output values of each connected aggregate must be set in the
rotary step switch.
The mini. output (0% of the load signal) and output (100% of the load signal) must
be set if the load output configuration is ( ).
The rotary step switch then distributes the load on the aggregates.
Set and connect the aggregates as follows:
Output Aggregate A ≤ Aggregate B ≤ Aggregate C ≤ Aggregate D
As shown in the examples below, the ratio of the loads determines the actual
output in the RMS705B. Sometimes however, it is easier for the commissioning
engineer, to set effective output.
