CnF. 3
- Main control output conditioning - [C.F06]
This parameter will be available only when main control output is
configured.
Range: norñ
= The control output is calculated by the PID.
CñPL = The control output is complemented (100-PID
calculated value).
Ouic = The control output is conditioned to match a
“QUICK OPENING” flow characteristic.
Eou = The control output is conditioned to match an
“EQUAL PERCENTAGE” flow characteristic.
NOTE about output conditioning
Sometimes non linear valves are used where a linear valve is
suitable.
In these cases, it is advisable to linearize the ratio between flow
rate and valve travel in order to obtain a better control of the
process.
This instrument allows you to select an output linearization in
accordance with the two most common valve flow characteris-
tics:
- Quick opening
- Equal percentage.
