The point of intersection of the tangent with the respective axis will
result in the parameters a and L.
Consult the manual of the control unit for connecting and program

ming details. Choose control upwards or downwards.
Control upwards/downwards
Setpoint:
User-defined process value (Measured value or flow)
P-Band:
Range below (upwards control) or above (downwards con

trol) the set-point, within the dosing intensity is reduced from 100% to
0% to reach the set-point without overshooting.

5.2.1.43.3
Reset time:
The reset time is the time till the step response of a sin
-
gle I-controller will reach the same value as it will be suddenly
reached by a P-controller.
Range: 0–9’000 sec
5.2.1.43.4
Derivative time:
The derivative time is the time till the ramp response
of a single P-controller will reach the same value as it will be sudden
-
ly reached by a D-controller.
Range: 0–9’000 sec
5.2.1.43.5
Control timeout:
If a controller action (dosing intensity) is constantly
over 90% during a defined period of time and the process value does
not come closer to the setpoint, the dosing process will be stopped
for safety reasons.
Range: 0–720 min
5.2.4
Signal Sequencer:
Only visible if a Sample Sequencer is connected.
Assign process value, the current loop range and a function to the
signal output.
5.2.4.1
Parameter:
Only the parameter “Si Sequencer” is available.
