Enable contact for
activated powder carbon/
UV disinfection unit
Activated powder carbon dosing systems or UV disinfection units can
be used for the reduction of the combined chlorine in the water.
A special controller is required for controlling these devices which pre-
vents excessive activation/deactivation (caused by flushing times on
activated powder carbon dosing systems, cooling phases on UV disin-
fection units).
The contact is enabled or disabled within the set control parameters
(Display 1.4.1).
If the entered Cl-N value (e.g. 0.20 mg/l) is exceeded, the controller out-
put switches on for the minimum duty cycle. As long as the Cl-N value
is exceeded, the controller output remains activated.
When the Cl-N value is no longer reached the controller output swit-
ches 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.
NOTE
In manual mode the minimum duty cycle and the minimum off-duty cy-
cle are ignored!
Control for
flocculant
dosing
A constant dosing output is provided for dosing of the flocculant.
The cycle period is permanently defined at 30 s.
The dosing rate is between 0 and 100 %.
The dosing rate in % is calculated on the basis of the circulation, the
container specifications and the dosing rate of the pump.
NOTE
Also refer to section 2.6.4 Special function "Flocculation control".
Controller stop function When the controller stop function is activ all controller outputs are set
to "0" (positioner to "0", dosing pumps stopped, pulse pumps stopped,
analog controller 0%, release contact off, dosing contact off). The out-
put for flocculation is also at 0%.
The DIN function is activ as long as the values are within the DIN limits.
