Loop 1 Split O/P*
The split output facility enables the
PID
control output (see page 30) to be split into 2 separate outputs. This enables heat
/ cool and other applications requiring dual outputs to be controlled. The linear relationship between the input from the
PID
algorithm and the 2 outputs is configured using the
Min
and
Max
Input / Output
parameters (see below).
When operating with
Split O/P
in
Manual
control mode, manual adjustment is made to the input at the split output block
(x axis). By default, the Operator page displays both output values (OP1 and OP2).

*Applicable only if the output type selected is
Split O/P
– see page 36.
