- Secondary control output bias - [C.F05]
This parameter will be available only when the split range is
enabled ("SPLt." [C.F01] = "Enb").
Range: from -100.0 to 100.0 % of the output span.
- 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.
The bias and gain of the two split outputs are the following:
“ñC.bS” [C.F03] is the Bias 1 applied to the main output
“ñC.Gn” [C.F02] is the Gain 1 applied to the main output
“SC.bS” [C.F05] is the Bias 2 applied to the secondary output
“SC.Gn” [C.F04] is the Gain 2 applied to the secondary output
- Main control output gain - [C.F02]
This parameter will be available only when the split range is
enabled ("SPLt." [C.F01] = "Enb").
Range: from 0.50 to 5.00.
- Main control output bias - [C.F03]
This parameter will be available only when the split range is
enabled ("SPLt." [C.F01] = "Enb").
Range: from -100.0 to 100.0 % of the output span.
- Secondary control output gain - [C.F04]
This parameter will be available only when the split range is
enabled ("SPLt." [C.F01] = "Enb").
Range: from 0.50 to 5.00
