Compound-Loop-Control
The compound-loop-control is a combination of the single feed
forward control with additional single feed back control to correct
control deviations.
Required module configuration:
•
MOD 1
-
To record measured value
•
MOD 5
- mA/V input module to record the
flow as well as the external setpoint
A typical application is for a flow-controlled chlorine dosing with
chlorine surplus correction for potable water treatment.
Input signals:
•
Flow rate measurement (0/4–20mA, 0–10V) scalable
(module 5)
•
Module 1 measured value recording
•
Internal or external setpoint (module 5)
Output parameter:
•
Dosing pumps
•
Solenoid pump
•
Positioner with feedback (1kOhm/5kOhm)
•
Continuous
