8.3.4 Binary step switch
Use the binary step switch to switch multistage aggregates. Size the aggregates
according to the binary load distribution.
 With the binary step switch, run priority changeover is not possible.
 Connect a modulating load signal to the output at aggregate A ( A).
In the binary step switch, digital outputs and number of load steps are assigned as
per the tables below to the entire switching capacity of the aggregate.
If configured without modulating output:
–
Configured
outputs
Cmd A
0 +2 A = 1/3
0 +3 A = 1/7
0 +4 A = 1/15
If configured with a modulating output:
–
Configured
outputs
Load A
1 +2 A = 1/4
1 +3 A = 1/8
0 = No modulating output.
1 = 1 modulating output.
Load assignment applies the following pattern:

0 % 100 %
