3.1 Assembly

The complete measuring system comprises:

• the measuring amplifier Conex

®

DIS-C

• the conductivity measuring cell with temperature
sensor.

3.2 Principles of conductivity
measurement

In metallic conductors, electricity is transported by
freely moving electrons, whereas in electrolytes, the
electrical current is carried by ions.
All water-dissolved components that are in ionogenic
form contribute towards conductivity.
The conductivity is a sum parameter.

Different types of ions vary in their electrical charge
and migration rate. The migration rate is highly
dependent on temperature, which means the
influence of temperature must always be taken into
account when measuring conductivity.

Specific electrolytic conductivity is measured in
Siemens per cm (S/cm). Siemens per cm is the
reciprocal value of electrical resistance.
This measurement is based on a theoretical liquid
cube with sides of a length of 1 cm. In practice, cells
rarely have such an even geometric shape. The cell
constant C is used to specify the correlation between
the actual measured conductivity and the displayed
specific conductivity.

The measuring cell is inserted in a flow armature,
and the water to be measured flows around it.
The Conex

®

DIS-C measuring and regulation device
amplifies the signal from the measuring cell and
calculates the signal (e.g. against cable and
temperature compensation parameters). The result
is displayed digitally and can also be registered
using the analog output. The result is shown as an
actual value.

9.4 Important instructions for connecting
the device

As is common in microprocessor-controlled devices,
certain precautions must be taken during installation
and wiring. In addition to the general guidelines, the
following is of particular importance:

• Input wires and control wires must be laid

separately from one another and from power
supply cables.

• Analog output wires must be screened.

The screen can be connected to the device.

• Relays and protective spools must remain free of

interference.

• If inductive loads are connected, they must either

be screened, or the relay contact must be
protected on the clamping strip of the
Conex

®

DIS-C by an RC protective circuit, in
accordance with the following table and the
switching diagrams.

9.4.1 Power supply

• The device is connected to the power supply at
the clamps (L), (N) and (PE).

• Check the correct supply voltage on the
nameplate.

9.4.2 Connecting the conductivity measuring cell

9.4.3 Relay outputs

If inductive loads (including relay and protective spools)
are connected, they must be screened. If this is not
possible, the relay contact must be protected using a
protection circuit in accordance with the table below.

For AC current

Fig. 10 Protection circuit with AC current

For DC voltage

The relay or protective spool must be screened with
a suppressor diode.

10. Principles of regulatory function

Freely selectable control functions mean that the
Conex

®

DIS-C controller can be adapted to a wide

variety of closed-loop control systems.

10.1 Regulatory behaviour

10.1.1 P regulation behaviour

The P controller has a static characteristic curve.
The characteristic proportional band for the P
controller is Xp. Within this range, which is limited to
a maximum or minimum depending on the control
direction, there is a proportional correlation between
the input and output quantities of the controller.

The lower limit is the response threshold of the
controller. This is the smallest regulatory deviation
that leads to a measurable control variable.

The upper limit separates the proportional band from
saturation. Above this limit, no further increase in
output signal is possible, regardless of increases in
the input signal. This range is called the control
range of the controller, and the control variable can
have any value within this range.

Due to the static characteristic curve, the P controller
cannot reach the setpoint in a stationary state.
This results in a consistent regulatory deviation,
which can be reduced by decreasing Xp, but which
cannot be completely eliminated using a P controller.

The controller reacts quicker with small Xp values.
The Xp value cannot, however, be reduced
arbitrarily, as this causes the controller to become
unstable.

10.1.2 I regulation behaviour

The non-delayed relationship between the regulatory
deviation and the control variable in a P controller
results in an undesirable persistent regulatory
deviation. However, if the regulatory deviation is
controlled directly by the regulating speed instead of
the control variable, this fixed assignment of the two
variables no longer applies. The result is an
integrated controller.

With a regulatory deviation of zero, i.e. when the
setpoint is equal to the actual value, the regulating
speed is also zero. Both positive and negative
regulatory deviations can be influenced by positive
or negative regulating speeds. The control variable
covers the whole control range. The control range of
the I controller is the range in which the regulatory
deviation controls the regulating speed in a linear
fashion.

The characteristic value of the I controller is the reset
time Tn. The reset time is the time that must elapse,
due to the integrated mode of action, for the step
response to reach the value that a P controller would
reach immediately.

The control circuit reacts slowly. If a regulatory
deviation results, an I controller can only react by
constantly changing its control variable. For this
reason, regulation with I controllers is always slower
than with controllers that act proportionally. If the
speed of the controller is increased by decreasing
the integration constant, the control circuit has a
slight tendency towards instability.

At Tn = 0, the controller has no I proportion.
In the absence of external influences, a control

circuit with an I controller therefore has no residual
regulatory deviation in a stationary state when the
control variable is constant.

10.2 Limit values

In principle, the limit value only has two switching
states; ON and OFF. Depending on the set control
direction, the controller is deactivated when the
setpoint value is exceeded, or when the value drops
below the setpoint.

10.2.1 Limit values with hysteresis

To prevent constant switching when the setpoint
value is reached, it is possible to specify a hysteresis
for the controller.

Example:

• setpoint 600 μS/cm

• hysteresis 10 μS/cm.
The hysteresis band is arranged symmetrically

around the switching point.

• Switch-off point = measured value + hysteresis / 2

• Switch-on point = measured value - hysteresis / 2.

Setting for a limit value: Xp = O.

10.3 On-off controller with P behaviour

It is possible to use an on-off controller with P
behaviour as an intermittent pulse regulator or as a
pulse frequency regulator.

10.3.1 Intermittent pulse regulator

Example:

• setpoint = 6 mS/cm

• measuring range 0 to 10

• Xp = 30

• control direction = downwards.
Xp determines the size of the proportional band as a

percentage of the measuring range. In the following
example, this means that above 6 mS the relay
switches on, first with a short activation time and
then with an increasing activation time to 9 mS (the
total switching on + off time remains constant).
For greater measured values, the relay remains
constantly switched on.

Fig. 13 Intermittent pulse regulator

The intermittent pulse regulation offers the option to
recreate a constant controlling element using very
simple control elements, e.g. a magnetic valve.
Here, the relationship between switching on and off
is changed depending on the calculated control
variable. The total time (ON+OFF) is constant in
intermittent pulse regulation. The total time can be
set to between 1 and 99 seconds depending on the
control system. A setting of 10 seconds leads to a
good result in most cases.

If the calculated control variable is very low, in some
cases it is possible that the control element attached
here does not show a reaction within this short time.
In this case, it is possible to set a minimum drive
pulse. This can be within the range 0.1 to

9.9 seconds.

10.3.2 Pulse-frequency regulator

Example:

• setpoint = 6 mS/cm

• measuring range 0 to 10

• Xp = 20 or 40

• pulse frequency = 120

• control direction = downwards.
Xp determines the size of the proportional band as a

percentage of the measuring range. In the following
example, this means that impulses are output from
6 mS and constantly increase to 8 mS (Xp = 20) or
10 mS (Xp = 40). For higher measured values, the
prespecified maximum number of impulses (here
120/min) is output.

Fig. 14 Pulse-frequency regulator

The pulse frequency regulator in combination with an
appropriate control variable is almost the same as a
continuous controller. The disadvantages of the
impulse-driven control variable only becomes
apparent in the lower control variable range and with
a low maximum pulse frequency. The specification of
the maximum pulse frequency refers to 100 %
dosing flow and can be set within a range from 0 to
180 impulses per minute.

Note

Setting for an on-off controller: Xp > O.

Note

Setting for an intermittent pulse regulator:
Xp > O, pulse frequency = 0.
