7.8 RC protection for relay

When connecting to the relay, note that inductive loads must be suppressed. If this is not possible, the relay contact on the device terminal must be protected by an RC protective circuit/interference suppression element.

If devices with inductive loads from a nominal current of 1 A are connected to a relay, the contacts in the relay may become bonded. Thus, the device will operate in an uncontrolled manner. To prevent bonding if the load circuit suffers a short-circuit, the relays must be protected separately on the maximum relay switching current.

8.2.1.5 Virtual inputs

You can calculate a new value from multiple measurements or reference values using a virtual input. You can assign the new virtual value to a controller in the conﬁguration assistant.

In this way, you can calculate a difference, the combined chlorine and the effective chlorine and use them as a basis for controlling your actors.

Difference

You can calculate the difference between two measured values or the difference between a measured value and a ﬁxed reference value.

Perform the following steps:

1. Working in the main menu under System > Inputs, navigate to the “Virtual” tab.

2. State the following information.

3. Calculation: Select “difference”.

4. Select a sensor.

5. Select a second sensor or a reference value. The second sensor must

output the same measured value as the ﬁrst. You will need to enter the reference value manually.

6. Min-alarm: Activate or deactivate the minimum alarm and state a difference value which, if it falls below a value, will trigger an alarm.

7. Max-alarm: Activate or deactivate the maximum alarm and state a difference value which, if exceeded, will trigger an alarm.

8. Delay: Set a time delay for the minimum and maximum alarm.

Conﬁguration of the difference completed.

ü

Combined chlorine

Combined chlorine is calculated from the difference between the total chlorine and the free chlorine:

Combined chlorine = total chlorine - free chlorine

At least one total chlorine measurement is required to calculate combined chlorine. The chlorine value can be entered manually as a single reference value or a corresponding sensor input is selected.

Perform the following steps:

1. Working in the main menu under System > Inputs, navigate to the “Virtual” tab.

2. Working in the “Virtual” tab, conﬁgure the desired calculation of the combined chlorine and state the following information.

3. Calculation: Select “Combined chlorine” to calculate the combined chlorine.

4. Total chlorine: Select the sensor which measures the total chlorine.

5. Free chlorine: Select the sensor which measures the free chlorine. If

no sensor is present, you can enter a reference value measured once which can be used for the calculation.

6. Min-alarm: Activate or deactivate the minimum alarm and state a value under which the alarm will be triggered.

7. Max-alarm: Activate or deactivate the maximum alarm and state a value over which the alarm will be triggered.

8. Delay: Set a time delay for the minimum and maximum alarm.

Conﬁguration of the combined chlorine completed.

ü

Effective chlorine

The disinfectant effect of the free chlorine is highly dependant on the pH value of the process water. The pH value inﬂuences the reactivity of the Chlorine ions. This relationship is underscored by the dissociation curve (Fig. 19 “Dissociation curve of the effective chlorine” on page 20) of the chlorine.

The actual disinfectant effect of the chlorine is generated by the hypochlorous acid (HClO). The ﬁgure shows that the proportion of the HClO is largest between pH 2 and pH 7.5. The disinfectant effect is very low outside this pH value.

For photometric measurements the pH value of the sample is buffered to approx. pH 6.5. As a result the measurement has a higher effective chlorine content than is actually in the process water. For high pH-values signiﬁcant differences will therefore occur between the expected and actual disinfection if assessed by photometric analysis. The calculation of the effective chlorine can be used to display the proportion of the hypochlorous acid (HCIO), i.e. the proportion which contributes to the disinfectant effect.

1. Working in the main menu under System > Outputs, navigate to the “External LEDs” tab.

2. Working under “LED”, select the desired LED.

3. Conﬁgure the LED by entering the following data.

4. Function: Select the reaction criteria for the LED. Selection of “Sam-

ple water missing” standardly results in a green LED. If the digital contact “Sample water missing” is active, it will illuminate red. Further options are the measured values of the sensor inputs 1 – 4.

5. Minimum and maximum: If you have decided to use a measured value, you must establish a minimum and a maximum value. The LED will illuminate red if the minimum value is undercut or the maximum value exceeded. It illuminates green between the values.

6. Testsignal: You can test the conﬁguration of the LEDs.

Conﬁguration of the external LED outputs completed.

Some actuators such as dosing pumps can be controlled directly via this output.

Perform the following steps:

1. In the main menu under System > Outputs, navigate to the “Analogue” tab.

2. Working under “Analogue”, select the desired output.

3. Conﬁgure the analogue output by entering the following data.

4. 20 mA type: You can choose between the following signal types:

4–20mA, 0 – 20 mA, 20 – 4 mA or 20 – 0 mA.

5. Testsignal: You can test the conﬁguration of the analogue outputs. Check the actuation on the external device.

6. Output: Determine what should be outputted on the selected output. You can choose between the measurement and temperature values or outputs (controller outputs).

7. Minimum: Determine a minimum value. The minimum value indicates for which measured value the signal is the weakest.

8. Maximum: Determine a maximum value. The maximum value indicates for which measured value the signal is the strongest.

The values for “minimum” and “maximum” serve the scaling of the analogue output signal. Example: Sensor 1 has a measuring range of 0 − 10 mg/l. 4 − 20 mA was selected as the 20mA type. If the complete sensor measuring range is to be covered by the analogue signal, 0 mg/l should be selected for “Minimum” and 10 mg/l for “Maximum”. At 0 mg/l, a 4 mA signal will be issued; at 10 mg/l a 20 mA signal will be issued.

Working in the menu item “Manual mode”, you can also switch the automatic switching of the setpoints on or off (9.6 “Setpoints and Setpoint sets” on page31).

9.5.1 pH

Calibration of the pH electrode can be performed as a 2-point calibration with 2 buffer solutions or a single point calibration with subsequent input of the slope of the sensor.

The actual voltage of the electrode and the ideal value of the set buffer solution is displayed during calibration.

The reaction time of a new electrode amounts to a few seconds and has been set when the physical value has become stable. Older electrodes can have a longer reaction time.

To perform the calibration performed here, you will require a buffer solution with a known pH value. Buffer solutions have a restricted storage life and their pH value changes depending on their duration of storage and the storage conditions.

Comply with the manufacturer’s instructions pertaining to the correct storage; use buffer solutions only within the scope of their life period and never submerge a sensor in a buffer solution immediately after removing it from a different buffer solution.

9.5.3 3-Electrode potentiostat and excess chlorine measuring cell CS120

You should calibrate a 3-electrode potentiostat or the potentiostatic measuring cells (chlorine sensors) as single-point calibration as a matter of course. You will require a photometrically measured value in accordance with the DPD method as a reference value.

With operation in a hot water system, electrochemical processes on the measuring electrode can result in a displacement of the zero point. In this case, 2-point calibration is necessary in which you calibrate the zero point using chlorine-free hot water. The second point is determined using the DPD method with chlorinated water as usual.

9.5.3.1 1-point calibration

To calibrate chlorine sensors, you will require a photometer with which to measure the reference value using the DPD method.

Pre-conditions for actions:

7. Conﬁrm the entry with the green checkmark.

4. You will be asked to set the ﬁrst reference value; this is the zero point.

If the zero point was mal-set by accident, set it by pinching off the measuring electrode and entering a value of zero. Should real 2-point calibration be performed, e.g. due to hot water, you must ﬁrst perform calibration with chlorine-free and then with chlorinated water. Enter a value for the zero point.

5. Conﬁrm the entry with the green checkmark.

6. Take sample water in immediate proximity to the measuring cell and

conﬁrm with “OK”. This means that the current signal at the time of the sample water extraction is saved to rule out signal ﬂuctuation as a measurement error during the DPD ascertainment.

9.6 Setpoints and Setpoint sets

You can determine various setpoints which should actuate the device. You have four different sets of setpoints; the controller can switch between them automatically. The setpoint sets can be used to vary the control at different times of the day or in different operating conditions.

The following section describes the possibilities of controlling using setpoints and their conﬁguration.

9.6.1 Setting the setpoints

You can conﬁgure and save the setpoints via the menu item “Setpoints”.

Perform the following steps:

1. Working in the main menu under “Setpoints” navigate to the “Active” tab.

2. Active: You can view the setpoint set currently active in the “Active” tab.

4The individual setpoints are displayed. If you change one of the val-

ues, it will immediately be activated as a new setpoint.

3. Save: You can save the active setpoints as a setpoint set. Select a setpoint set for this and press “Save".

4. Setpoints 1 − 4: The possible setpoints for the controller follow in sequence. The following information is displayed from left to right:

- S1 − S4/V1 − V4 indicates the sensor input or virtual input.

- O1 − O4 indicates the output. The “timer” indicates that the output is actuated directly.

- This is followed by the measured value of this input, e.g. free chlorine, pH or the text “No output” if this controller is inactive.

An upwards or downwards arrow indicates the control direction. Raise or lower.

- This is followed by the setpoint. Pressing on the setpoint enables you to change it immediately. If it is a 2-side control, two setpoints must be entered. Both for the control direction “Lift” or “Lower”. Changing these setpoints does not have an impact on the savable setpoint sets. To do so, you must perform step 3.

5. Flow rate: You can activate or deactivate the ﬂow. This enables you to reduce the ﬂow by between 0 % − 100 %. The value of the ﬂow is multiplied with the output Y. If the output is e.g. 80 % but the ﬂow is only 50 %, this produces an output capacity of: Control variable Y=80 % ∙ 50 % = 40 %.

2. Select the desired setpoint set.

3. Press "Load”.

4The desired setpoint set is active immediately.

Setpoint set loaded.

ü

9.6.3 Switching between setpoints

The setpoint sets set in the previous section can be switched manually or automatically. You have two possibilities to activate automatic switching.

1. Working in the “Setpoints” menu item, navigate to the “Switch-over” tab. Set a checkmark against “Switch setpoints automatically”.

2. Working in the “Manual mode” menu, set a checkmark against “Switch setpoints automatically”.

You can use a digital input (9.6.3.1 “Switching via digital input” on page 31) and multiple internal timers (9.6.3.2 “Switching via timer-switch” on page 32) for automatic switching. The switching via a digital input has priority. Switching via a timer only occurs if no switching is active via a digital input.

9.6.3.1 Switching via digital input

Before you can use a digital input for switching to a particular setpoint set, you must conﬁgure the digital input in accordance with section

8.2.1.6 “Digital inputs” on page21.

Switching can be performed in three different forms: externally-controlled switching; switching via an internal timer and the “ECO control” function, which includes the limit value control.

External switching

In the case of external actuation, switching to the desired setpoint set is performed as long as the digital input has been activated.

If the digital input is deactivated, the device switches back to the previous setpoint set.

To conﬁgure, working in the “Setpoints” menu item, select the “Switchover” tab and perform the following steps:

1. Conﬁgure the switching and state the following information.

2. Automatically switching the setpoint sets: Set a checkmark here.

15 Glossary

Operating instructions

Limit value control/DIN contact

The limit value control is an output which switches when determined limit values are exceeded or undercut. This function is used to

control an ECO or Night mode in a swimming pool with reduced circulation. If there are no swimmers in the swimming pool, energy and dosing media can be saved. The limit value control monitors the maintenance of the parameters.

In Germany, the limit values of the national standard DIN 19643 apply. As such, “DIN contact“ is a widespread name for this function.

Hysteresis

Hysteresis is the delayed response time of a two position controller,

when it reaches the “setpoint Y” and the control switches quickly between raising and lowering. As quick switching or control can have undesired effects, you can deﬁne hysteresis and achieve a more equal control.

Actual value X

The actual value ‘X’ is the continually measured value of a sensor.

Reset time Ki

The reset time ‘Ki’ is the integral proportion (I proportion) with PI and PID controllers. ‘Ki’ is the time required by the controller to alter the control variable ‘Y’, which is generated by the proportional range ‘Kp’ immediately after the step change of the control deviation ‘X-W‘.

You can set a reset time ‘Ki’ of up to 200 minutes.

P controller

A P controller is deﬁned by the proportional range ‘Kp’. The use of a pure P controller means that a control deviation ‘X-W’ always remains. The setpoint ‘W’ will thus never be reached.

PI controller

The PI controller is deﬁned by the proportional range ‘Kp’ and the reset time ‘Ki’. The use of the PI controller means that the actual value ‘X’

can reach the setpoint ‘W’.

The PI controller is suitable for the majority of applications.

PD-controller

The PD controller is deﬁned by the proportional range ‘Kp’ and the derivative time ‘Kd’. The use of a PD controller means that a control devia-

tion ‘X-W’ always remains. The setpoint ‘W’ will thus never be reached.

PID controller

Proportional range Kp

The proportional range ‘Kp’ (p proportion) of a P, PI or PID controller indicates the amount by which the actual value ‘X’ must deviate from the setpoint ‘W’ so that the variable Y = 100 %. If the control deviation ‘X-W’ is lower, the control variable is also lower.

The control variable ‘Y’ of a P controller is only affected by the control deviation ‘X-W’. The Kp value is stated in the unit of the variable to be controlled. If for example, during the control of the pH value, an Kp = 2 pH is selected and the actual value is X = 9 pH and setpoint W = 7 pH, the control deviation is X-W = 9 pH – 7 pH = 2 pH.

In this case, the deviation X-W is as large as the Kp value. In this case, the variable Y would be 100 %. With a decreasing deviation X-W, the control variable decreases in a linear fashion to 0 % with an actual value X = setpoint W.

Control deviation X-W

The control deviation X-W is the difference between the actual value ‘X’ and the setpoint ‘W’. The control variable ‘Y’ results from the control

deviation.

Setpoint W

The setpoint ‘W’ of a control is the desired value.

Control variable Y

The control variable ‘Y’ is the value with which the controller actuates the actor in accordance with its set parameters and the control deviation

‘X-W’. The value lies between 0 % and 100 %.

Derivative time Kd

With PD or PID controllers, the differential proportion (D proportion) is deﬁned with the derivative time ‘Kd’. The D proportion ensures that the

control path already contains a correction factor at the point at which the actual value "X" begins to differ from setpoint "W". The

control variable ‘Y’ depends on the speed with which the control deviation ‘X-W’ takes place. The duration of the correction is determined by the derivative time ‘Kd’. If the actual value ‘X’ does not change, i.e. the speed of change is “0”, the correction factor effected by the D proportion with the derivative time ‘Kd’ drops as far as “0” (even if the actual value ‘X’ does not match the setpoint ‘W’, but consistently deviates from it). The fact that the control system causes the actual value ‘X’ to match the setpoint ‘W’ is due mainly to the I proportion of the controller. The D proportion often improves the controller behaviour because it acts against the trend to deviate.

The derivative time Kd can be set from 0 seconds to a maximum of 1200 seconds.

The PID controller is deﬁned by the proportional range ‘Kp’, the reset time ‘Ki’ and the derivative time ‘Kd’. The integral gain means that the actual value ‘X’ can reach the setpoint ‘W’.
