Configuring the conductivity controller
Setting the flushing interval and flushing time of the continuous blowdown valve
Open the “Valve” menu.
Description of display/settings
Tt
Valve runtime, see page 57
If the actual value/manipulated
variable output is configured as a
manipulated variable output (Yw),
the valve runtime is no longer
shown and therefore has no impact
on control behavior. The manipu-
lated variable therefore changes
rapidly.
Flushing interval
Flushing time
Activate 24h flushing.
Press the button to activate 24h
flushing.
Setting the flushing interval and flushing
time
You can enter the desired times, within their
limits, in the input fields.
When the set interval has elapsed, the flushing
interval is activated and moves the valve to
“Open” for the set time.
When the set flushing interval has elapsed, the
valve returns to the “Closed” position for the
set time.
The incrementing times are shown in the
parameters.
Feedback of this action is shown on
the home screen and in the bar charts,
see page 57.
Active parameters when a feedback poten-
tiometer is connected to the conductivity
controller.
The current valve position is shown in percent.
