10.6.3 Binary step switch
The binary step switch is used to switch multistage aggregates. The aggregates
must be sized according to the binary load distribution.
With the binary step switch, run priority changeover is not possible.
In the binary step switch, the digital outputs are distributed across the entire
switching capacity of the aggregate in the following load increments:
0Y+2 Q 1.Q = 1/3 2.Q = 2/3 3 load increments
0Y+3 Q 1.Q = 1/7 2.Q = 2/7 3.Q = 4/7 7 load increments
0Y+4 Q 1.Q = 1/15 2.Q = 2/15 3.Q = 4/15 4.Q = 8/15 15 load increments
If configured with an analog output:
1Y+2 Q Y = 1/4 1.Q = 1/4 2.Q = 2/4 4 load increments
1Y+3 Q Y = 1/8 1.Q = 1/8 2.Q = 2/8 3.Q = 4/8 8 load increments
