Description
700 P electronics module
3.
The CEDOX control system is based on the following principle:

The example diagram below shows how the CEDOX mode works:
Image 4 Operating principle of the CEDOX operating mode
Notes for settings for CEDOX control:
In CEDOX mode, a ORP setpoint is generally set. A neutral band
Xsh defines what the maximum deviation from the mV setpoint is.
If the deviation is greater than Xsh, the 700 P electronics module
defines a new Cl
2
setpoint.
The parameter “mV delay time” defines the reaction time of the
ORP electrode and has a delaying effect on the setpointoptimiza-
tion of the chlorine control.
The Cl
2
setpoint values defined by the CEDOX operating mode
must remain between the limit values of the "Cl2 min. setpoint" and
the "Cl2 max. setpoint." If these setpoint limits are reached, the mV
measured value may vary from the mV setpoint.
