3.4.1 Controller Outputs
The 700 P electronics module supports the following controller
outputs:
Positioner (with and without
feedback) With the selection of the integrated controller for "positioner", for example, it is possible to use chlorine overfeed control in connec-
tion with a positioner as an actuator of a chlorine gas dosing sys-
tem.
2-point pulse duration controller
for dosing pumps The dosing pump is switched on for the calculated time within an adjustable cycle period Tp (relay contact). The cycle period is
mainly determined by the reaction time of the connected system
and entered as the cycle period Tp. Example:

2-point pulse frequency
controller for pulse pumps Pulse pumps are controlled with 0 to 100/120/140/160/180 pulses per minute, depending on the specification of the connected pump.
The duty cycle during each dosing is 0.3 s. The break time is cal-
culated to be between 0.2 and 60 s, depending on the dosing rate.
Example of a pulse pump at 120 pulses/min:
3-point pulse duration controller
for dosing pump and 3-point
pulse frequency controller for
Pulse pump
Pump 1 decreases the control value,
Pump 2 increases the control value.
The control rangeis between -100% (Pump1) and +100% (Pump
2); this range can also be set in manual mode.
If the setpoint = actual value, no pump is activated (neutral zone
Xsh).
Output signals as for 2 point pulse-duration controller and 2-point
pulse-frequency controller.
Controller with mA output The 700 P electronics module has a maximum of four analog mA
outputs. These can be assigned individually as registration or con-
troller outputs or as controller output when selecting “Analog out-
put 2P” or “Analog output 3P” it is necessary to assign the desired
mA output 1 to 4.
Analog output controller 2-point With a control output of 0%, the output current is 0 or 4 mA; with a
higher control output, the output current reaches up to 20 mA.
Pumps with current input, thyristor control units with DC or AC
pumps, or analog control valves can be used as actuators.
Analog output controller 3-point Pump 1 decreases the control value,
Pump 2 increases the control value.
Output behaviour is similar to "Analog output controller (2-point)",
but with 50 % offset. This means that with a control deviation of 0
% (setpoint = actual value) a current of 10 mA or 12 mA is output
(pump is idle).
Therefore, two suitable pumps can be actuated with one mA cur-
rent loop.

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
powderactivated carbondosingsystems or UVsystems.Aspecial
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).
Renewedactivation when thesetpointisexceededisonlypossible
when the minimum off-duty cycle has elapsed.
Please note
In manual modethe minimum duty cycle and theminimum 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 remainsactiveaslong as the DINlimitvaluesare
kept.
Controller STOP is triggered by the digital inputs, e.g. by sample
water STOP or circulation off.

3.4.2 Control parameters
Control parameters are setting values used to determine the con-
trol response ofa controller.Different parameters apply depending
on the type of controller.
Please note
The control parameters are listed alphabetically.
Pulses max./min
Setpoint
Tn
Maximum number of pulses
Description The max. pulses/min parameter only applies
to pulse pumps.
This parameter is used to set the maximum
number of pulses per minute in accordance
with the pump used.
Setting range The max. pulses/min parameter can be set to
100/120/140/160/180 pulses.
Setpoint
Description Specified value at which the control value
(chlorine, pH, total chlorine, conductivity) can
be maintained by the controller.
Setting range The setting range corresponds to the respec-
tive measuring range.
Integral action time (I-element)
Unit Minutes (min)
Description On the basis ofthe integral actiontime Tn, the
dosing rate changes constantly until the set-
point is reached. The higher the value of Tn,
the longer it takes until the controller
increases the dosing rate.
Tn higher: Control response is slower
Tn lower: Control response is faster
Setting range The parameter Tn can be set from 0 to 100
min (Tn = 0 means that the "I-element" is
deactivated, i.e. a pure P-control response
applies). It may not be possible to reach the
setpoint value.
