Proportional outputs can be used in the following way:
Output with one relay:
An output range is defined with a
Start value
and an
End value
. No output
takes place above and below the output range (see page 99).
Output with two relays:
An output range is defined for each relay with a
Start value
and an
End value
.
One relay outputs in the upper output range and a further relay in the lower
output range (see page 99).
