5.2 Local Operation

5.2.1 Automatic/manual mode

The transmitter normally operates in automatic mode. Here, the relays are triggered by the transmitter. In the manual mode, you can trigger the relays using the REL key or start the cleaning function. How to change the operating mode:

Pay attention to the following:

• The selected operating mode remains in effect even after a power failure.

• The manual mode has priority over all automatic functions (Hold).

• Hardware locking is not possible in the manual mode.

• The manual settings are kept until they are actively reset.

• Error code E102 is signalled in the manual mode.

1. The transmitter is in Automatic mode. The top LED beside the

AUTO key is lit.

2. Press the AUTO key.

3. To enable the manual mode, enter the code 22 via the PLUS and

MINUS keys. The bottom LED beside the AUTO key lights up.

4. Select the relay or the function.

You can use the REL key to switch between the relays. The relay selected and the switch status (ON/OFF) is displayed on the second line of the display. In the manual mode, the measured value is displayed continuously (e.g. for measured value monitoring for dosing functions).

5. Switch the relay. It is switched on with PLUS and switched off with

MINUS. The relay remains in its switched state until it is switched over again.

6. Press the AUTO key to return to the measuring mode, i.e. to the

automatic mode. All the relays are triggered again by the transmitter.

Hold function: "freezing" of the outputs

During setup and calibration, the current output can be "frozen". It constantly retains its current status. "HOLD" appears on the display. If the controller actuating variable (steady control 4 to 20 mA) is output via current output 2, it is set to 0/4 mA in Hold.

Pay attention to the following:

• Hold settings can be found in the "Service" section.

• During Hold, all contacts will go to their normal positions.

• An active Hold has priority over all other functions.

• With every Hold, the I-component of the controller is set to zero.

• Any alarm delay is reset to "0".

• This function can also be activated externally via the Hold input (see Wiring diagram; binary input 1).

• The manual Hold (field S3) remains active even after a power failure.

6.4 System configuration

6.4.1 Setup 1 (Conductivity)

Wall distance

The sensor’s distance from the pipe wall affects the measuring accuracy ( å 17). In narrow installation conditions, the ion flow in the medium is affected by the pipe walls. This effect is compensated by the so-called installation factor. When the distance from the wall is sufficient, i.e. a > 15 mm / 0.59", the installation factor can be ignored (f = 1.00). When the wall distance is lower, the installation factor increases in the case of electrically insulating pipes (f > 1) while it decreases for electrically conductive pipes (f < 1);  å 17. The determination of the installation factor is described in the chapter "Calibration".

6.4.2 Setup 2 (Temperature)

The temperature coefficient  specifies the change in conductivity per degree of temperature change. It depends on the chemical composition of the medium and the temperature itself. In order to compensate for this dependence, four different compensation types can be selected in the transmitter:

• Linear temperature compensation

• NaCl compensation

• Temperature compensation with table

Linear temperature compensation

The change between two temperature points is considered to be constant, i.e.  =const. The  value can be edited for the linear compensation type. You can edit the reference temperature in field B7, the factory setting is 25 °C (77 °F).

NaCl compensation

The NaCl compensation (according to IEC

60746) is based on a fixed nonlinear curve that defines the relationship between the temperature coefficient and the temperature. This curve is used for lower concentrations of up to approx. 5 % NaCl.

6.4.5 Check

Polarisation detection

Polarisation effects in the interface between sensor and measuring solution limit the measuring range of conductive conductivity sensors. The transmitter has the ability to detect polarisation effects using an intelligent evaluation process. Error code E071 will be generated.

PCS alarm (Process Check System)

This function (field P2) is used to check measuring signals for deviations. If the measuring signal is constant during the selected time frame, an alarm (E152) is triggered. The reason for such sensor behaviour can be contamination, cable rupture or similar.

6.4.6 Relay contact configuration

To use the RELAY function group you need a relay board which is not part of the basic version.

Limit contactor for measured conductivity value and temperature

The transmitter has different ways of assigning a relay contact. Switch-on and switch-off points and pick-up and drop-out delays can be assigned to the limit contactor. In addition, you can configure an alarm threshold to output an error message and to start a cleaning function in conjunction with this. These functions can be used both for conductivity measurement and for temperature measurement.

Please refer to Fig. 22 for a clear illustration of the relay contact states.

• When the measured values increase (maximum function), the relay contact is closed as of t

after the switch-on point (t1) has been overshot and the pick-up delay has elapsed

2-t1

The alarm contact switches if the alarm threshold (t

) is reached and the alarm delay

4-t3

) (field F3) has also elapsed.

• When the measured values decrease, the alarm contact is reset when the alarm threshold (t

) is undershot as is the relay contact (t7) after the drop-out delay (t7-t6).

• If the pick-up and drop-out delays are set to 0 s, the switch-on and switch-off points are also switch points of the contacts.

Settings can also be made for a minimum function in the same way as for a maximum function.

6.4.9 Concentration measurement

The transmitter can convert conductivity values to concentration values. For this, set the operating mode to Concentration measurement (see field A1). Then, you must enter the basic data to which the concentration calculation should refer. You require the conductivity characteristics of the medium. To get the characteristics, you can either refer to the data sheets of the medium or determine the characteristics yourself.

1. To do so, create samples of the medium with the concentrations occurring in your

process.

2. Measure the uncompensated conductivity of these samples at temperatures which

likewise occur in your process. – For variable process temperature:

If the variable process temperature should be taken into account for concentration measurement, you must measure the conductivity of each created sample at two different temperatures at least (ideally at the lowest and highest process temperature). The temperature values for the various samples must be identical. However, the difference between the temperatures must be at least 0.5 °C. At least two differently concentrated samples measured at two different temperatures are required because the transmitter needs a minimum of four references.

– For constant process temperature:

Measure the differently concentrated samples at this constant process temperature. A minimum of two samples is necessary.

Finally, you should have measuring data which are similar to those shown in the following figures:

• Constant process temperature: Enter at least two value triplets.

Pay attention to the following:

• Please make sure that the concentrations and temperatures measured for your samples correspond to the measuring range of the process. If the measured values of the process are outside the range of your sample values, this considerably reduces the level of accuracy and the error message E078 or E079 will be displayed.

• If you enter an additional value triplet of 0 μS/cm and 0 % for each temperature used, you can work from the start of measuring range with sufficient accuracy and without an error message. Enter the values in the order of increasing concentration (see the following example).

Compensation of the internal resistance

If you use a conductive sensor in higher conductivities (> 45 mS/cm) you should compensate the internal resistance of the transmitter. Otherwise a measuring error of more than 1 % could occur in some cases. With the fields S12 to S14 the transmitter determines and saves its internal resistance. The conductivity will be compensated by this value. Inductive sensors do not require such a compensation.

To perform the compensation proceed as follows:

1. Disconnect the transmitter from power.

2. Remove the transmitter.

3. Disconnect the sensor and connect the test resistor (included in the delivery) at the

terminals 83 and 84. Use the delivered resistor - no other one!

4. Reconnect the power.

5. Perform the menu fields S12 to S14.

To reinstall the transmitter proceed as follows:

1. Disconnect the transmitter from power.

2. Remove the test resistor.

3. Connect the sensor (see chapter "Wiring").

4. Reinstall the transmitter (see chapter "Installation").

5. Reconnect the power.

The cable resistance is not considered (see field A6).

6.5 Calibration

To access the "Calibration" function group, press the CAL key. This function group is used to calibrate and adjust the transmitter. Two different types of calibration are possible:

• Calibration by measurement in a calibration solution of a known conductivity.

• Calibration by entering the exact cell constant of the conductivity sensor.

Pay attention to the following:

• At first start-up of inductive sensors, an airset is absolutely required in order for the measuring system to be able to generate accurate measuring values.

• If the calibration procedure is aborted by pressing the PLUS and MINUS keys at the same time (return to C114, C126 or C136) or if the calibration is faulty, then the previous calibration data are reinstated. A calibration error is indicated by the “ERR” message and flashing of the sensor symbol on the display. Repeat calibration!

• The instrument is automatically switched to hold during calibration (factory setting).

• After calibration, the system jumps back to the measuring mode. During the hold dwell period the hold symbol is displayed.

• For conductive sensors only the fields C121 to C126 are relevant.

The error number is shown below the display of the main measured value. If more than one error occurs, you can call these up with the MINUS key. Refer to the "System error messages" table for the possible error numbers and remedial measures. Should a malfunction occur without any transmitter error message, please refer to the "Process-specific errors" or the "Device-specific errors" tables to localize and rectify the error. These tables provide you with additional information on any spare parts required.

8.1.4 Simulation of inductive sensors for device test

The inductive sensor cannot be simulated. However, the overall system comprising the transmitter and inductive sensor can be checked using equivalent resistances. Note the cell constant (e.g. k

nominal

= 5.9 cm-1 for CLS52,

nominal

=6.3cm-1for CLS54).

For an accurate simulation, the actual cell constant (can be read in field C124) is to be used to calculate the display value. The exact formula depends on the sensor type: CLS52: Display conductivity [mS/cm] = k(cm

-1

) 1/R [k]

CLS54: Display conductivity [mS/cm] = k(cm

-1

) 1/R [k]  1.21

Values for simulation with CLS54 at 25 °C (77 °F):

Conductivity simulation:

Pull a cable through the sensor opening and then connect, e.g. to a decade resistor.

8.1.5 Check of conductive sensors

• Measuring surface connection: The measuring surfaces are directly connected to the connections of the sensor connector. Check with ohmmeter at < 1 .

• Measuring surface shunt: There may not be any shunt between the measuring surfaces. Check with ohmmeter at > 20 M.

• Temperature sensor shunt: There may not be any shunt between the measuring surfaces and the temperature sensor. Check with ohmmeter at > 20 M.

• Temperature sensor: You can find out the type of the temperature sensor being used by consulting the sensor nameplate. The sensor can be checked at the sensor connector with an ohmmeter: – Pt 100 at 25 °C (77 °F) = 109.79  – Pt 1000 at 25 °C (77 °F) = 1097.9  – NTC 10 k at 25 °C (77 °F) = 10 k

• Connection: For sensors with a terminal connection (CLS12/13) check the assignment of the terminals for reversals and the tightness of the terminal screws.

8.1.6 Check of inductive sensors

The sensor lines on the instrument or junction box are to be disconnected for all tests described here!

• Testing transmitting and receiving coils – Ohmic resistance

CLS52: approx. 0.5 to 2  CLS54: approx. 1 to 3 

– Inductivity (at 2 kHz, series connection as equivalent circuit diagram)

CLS52/54: approx. 180 ... 550 mH (Measure the white and red coaxial cables, between the inner conductor and screen in both cases.)

• Testing the coil shunt – A shunt between the two sensor coils is not allowed. The resistance measured should be

>20 M.

Test with ohmmeter between red coaxial cable and white coaxial cable.

• Testing the temperature sensor Use the table in chapter "Simulation of inductive sensors for device test" to check the Pt100 in the sensor. Measure between the green and white wires and between green and yellow. The resistance values should be identical.

• Testing the temperature sensor shunt – Shunts between the temperature sensor and the coils are not allowed. Check with

ohmmeter for >20 M. Measure between the temperature sensor wires (green + white + yellow) and the coils (red and white coaxial cables ).

8.1.7 Connecting lines and junction boxes

• Use the methods described in chapters "Simulation of conductive/inductive sensors for device test" to perform a quick functional check from the conductivity sensor (sensor connector) to the measuring instrument via an extension. Connect the decade resistors simply with the service kit "Conductivity Test Adapter", order no. 51500269 (for CLS15, CLS19, CLS21).

• Check junction boxes for: – Moisture (influence at low conductivity, if necessary dry box, replace seals, insert

dehydrating bag) – Correct connection of all lines – Connection of the outer screens – Tightness of the terminal screws

9.3 Replacing the central module

Generally, when a central module has been replaced, all data which can be changed are set to the factory setting.

Proceed as described below if a central module is replaced:

1. If possible, note the customized settings of the device, such as: – Calibration data – Current assignment, main parameter and temperature – Relay function selections – Limit value/controller settings – Concentration tables – Monitoring functions –ATC tables – MRS settings

2. Disassemble the device as explained in the "Dismantling the panel-mounted instrument" or "Dismantling the field instrument" section.

3. Use the part number on the central module to check whether the new module has the same part number as the previous module.

4. Assemble the device with the new module.

5. Start up the device again and check the basic functions (e.g. measured value and temperature display, operation via keyboard).

6. Enter the serial number: – Read the serial number (“ser-no.”) off the nameplate of the device. – Enter this number in the fields E115 (year, one-digit), E116 (month, one-digit), E117

(cons. number, four-digit).

– In the field E118, the complete number is displayed again so you can check it is

correct.

You can only enter the serial number for new modules with the serial number

0000. This can only be done once! For this reason, make sure the number entered is correct before you confirm with ENTER! Entry of an incorrect code will prevent the additional functions from being enabled. An incorrect serial number can only be corrected at the factory!
