Setpoint Trim
This controller type consists of a compound-loop-control with
adaptive setpoint. A second measurement controls possible
controldeviations, which, for example, arise as a result of attrition
in the delay tank. The compound-loop-control's adaptive setpoint
adjustment automatically equalises control deviations developing
in the system.
Input signals:
•
Flow measurement (0/4–20mA, 0–10V) scalable
•
Measured variable 1 compound-loop-control
(Sensor module 1 - Cl
2
, pH, mA, – )
•
Measured variable 2 control measurement
(Sensor module 2 - Cl
2
, pH, mA, – )
The following requirements must be met:
Measured variables 1 and 2 must be equal measurements with the
same unit. The format (e.g. 00.00, 0000, 000.0) must be identical
as well.
The measuring range may differ (e.g. mod. 1 = 10.00 mg/l, mod. 2
= 5.00 mg/l).
When using different sensor measuring modules (e.g. Cl
2
= Mod1,
mA/V = Mod2), the measuring ranges must be adjusted
accordingly.
