Configuring the conductivity controller
Continuous blowdown valve - Setting the flushing interval and flushing time
Open the “Valve” menu.
Description of display/settings
Tt
Valve runtime, see page 62
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
behaviour. The manipulated variable
therefore changes rapidly.
Activate 24h flushing.
Press the button to activate 24h flushing.
Flushing interval
Flushing time
Setting the flushing interval and flushing time
You can enter the desired time, within their limits,
in the input fields.
When the set interval has elapsed, the flushing in-
terval 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 param-
eters.
Feedback of this action is shown on
the home screen, and in the bar charts,
see page 46.
Active parameters when a feedback poten-
tiometer is connected to the conductivity
controller.
The current valve position is shown in percent.
