Dosing contact
A dosing contact is used to actuate electrolysis systems for chlo-
rine dosing or to reduce the combined chlorine in the water with
powder activated carbon dosing systems or UV systems. A special
controller is required to drive these systems in order to prevent fre-
quent switching on or off (on account of flushing times on powder
activated carbon systems, cooling phases on UV systems).
The contact is enabled or disabled within the set control parame-
ters.
If the Cl-N value entered is exceeded (e.g. 0.20 mg/l), the control-
ler output switches on for at least the minimum duty cycle. As long
as the Cl-N value is exceeded, the controller output remains on.
When the Cl-N value is not reached, the controller output switches
off immediately (provided that the minimum duty cycle has
elapsed).
Renewed activation when the setpoint is exceeded is only possible
when the minimum off-duty cycle has elapsed.
Please note
In manual mode the minimum duty cycle and the minimum off-duty
cycle are ignored!
For dosing contact, there is no monitoring of the max. dosing time.
Controller STOP function
When the controller STOP function is active, all controller outputs
are switched off (positioner closed, dosing pump off, pulse pumps
off, analog output controller 0%, enabling contact off, dosing con-
tact off).
The flocculation output is also switched off.
The DIN function remains active as long as the DIN limit values are
kept.
Controller STOP is triggered by the digital inputs, e.g. by sample
water STOP or circulation off.
