Adaption (only applies to free Cl
2
)
The adaption programme automatically determines the control
parameters for free chlorine during commissioning. The adaption
can be run separately for normal operation and ECO mode in order
to find the suitable controller parameters for both operating modes.
Application
The adaption is used for automatic ascertainment of the reaction
times of the control loop (loop dead time Tu and loop rise time Ts)
or the resulting control parameters Xp and Tn.
Please note
The control parameters Xp and T ascertained by the adaption
must be considered as a recommendation for the first commission-
ing!
The control parameters Xp and Tn can be manually optimized to
ensure maximum control quality.
Requirements
The following requirements must be met:
•
Positioner set to automatic (manual wheel engaged)
•
Dosing pump set to automatic
•
Calibrated Cl
2
measuring (zero point and DPD value)
•
Loop dead time < 60 min
•
Loop rise time < 480 min (8 h) for 0 to 100 % measurement
range
•
Decomposition time < 480 min (8 h) of the current measuring
value to 20% of the 2x setpoint
•
Correct menu setting of the end value, control direction (direct
or inverse), actuator (e.g. positioner), positioner running time
(Ty)
Adaption may not be started:
•
If a large volume of fresh water is being added
•
If the measuring cell has not been run in
•
During cleaning work
•
During filter backwashing
•
While the circulation changes
•
During peak chlorination
