General programming instructions
The difference between the setpoint w and the measurement x corresponds to the regulation error, which is
filter by a dead band.
Dead band A eliminates small regulation errors. The filtered control error is transmitted to the P.I.D
calculator which consists of three components. Proportional P, Integral I and Derivative D. The integral (in green)
also has an anti-saturation system for limiting the action of the integral.
The sum of the three components gives a need for regulation Y which is limited according to the actuators
you use, B (-100% to 0% or 0% to +100% or -100% to +100%).
 E01 pH PI1
- Parameter identification, includes information on parameter number (E01), type (pH) and associated
main sensor input (
PI1)
 Mode P.I.D
- Dosage mode selection, on this selection button we find the selected mode information (P.I.D). Press
to modify.
 Setpoint 7,20 pH
- Enter the setpoint value. Here the value is (7,20).
Press to open the numeric keyboard and enter the desired value.
 Dead band 0,01 pH
- Enter the dead band value. Here the current value is (0,01).
Press to open the numeric keyboard and enter the desired value.
 Intergral OFF
- Enter the integral value. Here it’s disabled, current value is (OFF).
Press to open the numeric keyboard and enter the desired value.
 Derivate OFF
- Enter the derivate value. Here it’s disabled, current value is (OFF).
Press to open the numeric keyboard and enter the desired value.
When the integral and the derivate are OFF the dosing mode is PROPORTIONAL.
When only the derivate is on OFF the dosing mode is PROPORTIONAL INTEGRAL.
If all values are entered the dosing mode is PROPOTIONAL INTEGRAL DERIVATE.
 Basic load OFF % - Maximum time OFF min – Activation threshold 90 %
- See Hysteresis dosing mode
Save:
- When a change is made, the “SAVE” button appears (floppy icon), you must save your configuration
by pressing it.
