4.1 General information

4 Mounting

Mounting location

Installation position

Find a location that ensures easy accessibility for the later calibration. The fastening must be secure and must ensure low vibration for the

instrument. Avoid direct sunlight! Permissible ambient temperature at the installation location: -10 to +55 °C

with max. 95 % rel. humidity, no condensation. The instrument can be mounted in any position.

4.2 Dimensions

Close mounting

Minimum spacing of panel cutouts Horizontal Vertical Without setup connector: 30 mm 11 mm With setup connector (see arrow): 65 mm 11 mm

5 Installation

5.1 Installation instructions

The electrical connection must only be performed by qualified personnel!

❏ The choice of cable, the installation and the electrical connection must

conform to the requirements of VDE 0100 “Regulations on the Installation of Power Circuits with Nominal Voltages below 1000 V” and the relevant local regulations.

❏ At maximum load, the cable must be heat resistant up to at least 80 °C. ❏ The device is intended to be installed in electrical cabinets. It shall be

operated by mains protected with a branch circuitry overcurrent protection device not more than 20 Amps. For servicing/repairing a Disconnecting Device shall be provided to disconnect all conductors.

❏ The load circuits must be fused for the maximum load currents in each case

to prevent the relay contacts from becoming welded in the event of a short circuit.

❏ Electromagnetic compatibility meets the requirements of EN 61326. ❏ Lay the input, output, and supply lines so they are physically separated

from each other and are not parallel.

❏ Use twisted and shielded probe cables. If possible, do not lay these cables

close to components or cables through which current is flowing. Ground the shielding at one end.

❏ The probe cables must have an uninterrupted run (do not route them via

terminal blocks or similar arrangements).

❏ No other consumers can be connected to the power terminals of the

instrument.

❏ The instrument is not suitable for installation in areas with an explosion

hazard.

❏ Apart from faulty installation, incorrect settings on the instrument may also

affect the proper functioning of the subsequent process or lead to damage. You should therefore always provide safety equipment that is independent of the instrument and it should only be possible for qualified personnel to make settings.

8 Calibrating a conductivity sensor

8.1 Notes

During calibration, relays and analog output signals adopt their configured states!

When is calibration required?

- The temperature coefficient of the sample medium must be determined once.

- The cell constant must be calibrated at regular intervals (depending on the sample medium and requirements).

Every successfully completed calibration is documented in the calibration logbook, see chapter 10 "Calibration logbook", page 73.

8.2 General information

The electrical properties of all sensors vary slightly from instance to instance and also change during operation (due to deposits or wear, etc.). This changes the output signal of the sensor.

8.2.1 Measurements in highly-purified water

Measurements in highly-purified water (measured values < approx. 10 µS/cm) make special demands on the metrology and the measurement environment.

The following points should therefore be considered and checked first before attempting a calibration:

- Basically sensors with ASTM certificate are recommended for measurements in highly-purified water. Their cell constants are measured by the manufacturer and can be found in the certificate.

- Ready-to-use calibration solutions in the range < 5 µS/cm are difficult or impossible to get. Effort and error rate are very high when handling these.

- Reliable comparative measurements are often problematic due to unknown or insufficient quality of the comparison device. In addition, the reference junction is often not close enough to the actual measuring point.

- If minor measurement errors exist despite of entering the exact cell constant, these can manually be adjusted in the range of several percent by changing the relative cell constant. Possible causes are installation conditions and flow dependencies.

- Larger deviations (> approx. 10 %) mostly have other causes, such as contamination of the sensor by mishandling or EMC.

More information on highly-purified water measurement in form of a scientific paper can be found on the Internet at www.jumo.de.

For this purpose, enter the keyword "FAS 614" into the search box.

8 Calibrating a conductivity sensor

PGM

8.2.2 Requirements

- The instrument must be supplied with voltage, see chapter 5 "Installation", page 14 ff.

- A conductivity sensor must be connected to the transmitter.

For a configuration example see chapter 7.2.1 "Conductivity measurement, temperature compensated", page 41.

A conductivity sensor be

- connected directly to the main input or

- connected to the "Analog input (universal)" optional board via a transmitter.

- "Conductivity" must be configured as operating mode in the basic setting.

- The instrument is in Measuring mode.

8.2.3 Ways to start the calibration

Select the input to which the conductivity sensor is connected.

If Calibration level is not released

Press the key for longer than 3 seconds/ADMINISTR.-LEVEL/ PASSWORD/CALIBR.-LEVEL/MAIN INPUT or ANALOG INPUT.

If Calibration level is released

Press the and keys simultaneously/MAIN INPUT or ANALOG INPUT.

If Calibration level is released

Press the key for longer than 3 seconds/CALIBR.-LEVEL/MAIN INPUT or ANALOG INPUT.

8.2.4 Calibration options

The instrument provides two calibration options for adjusting the JUMO dTRANS 02 CR to the measuring point:

Calibration of the temperature coefficient

See chapter 8.4 "Calibrating the relative cell constant", page 51.

Calibration of the cell constant

See chapter 8.4 "Calibrating the relative cell constant", page 51.

8.3 Calibration of the temperature coefficient of the sample medium

✱ Make preparations, see chapter 8.2 "General information", page 47. ✱ Start calibration, see chapter 8.2.3 "Ways to start the calibration", page 48. ✱ Select "TEMP.COEFF. LIN.".

Now the source of temperature acquisition can be selected (manually, or using the temperature input of the PSU board, or the temperature input via the optional board). This source will be active for the duration of the calibration.

An example follows: automatic temperature acquisition using the temperature sensor integrated into the conductivity sensor.

The current sensor temperature appears in the display (+ flashing) (1).

✱ Enter the required working temperature and confirm your entry with the

key.

The working temperature must be at least 5 °C above or below the reference temperature (25.0 °C).

8 Calibrating a conductivity sensor

PGM

EXIT

The conductivity (399 µS/cm) at the current temperature (24.3 °C) now appears on the right of the LC display. The temperatures T1 (25 °C) and T2 (70.0 °C) that have yet to be triggered are shown on the left.

✱ Heat the sample medium until the working temperature is reached.

During calibration, the rate of temperature change in the measurement solution must not exceed 10 °C/min.

Calibration is also possible in the cooling process (with a falling temperature). It starts above the working temperature and ends below the working temperature.

As soon as the temperature of the sample medium exceeds T1 (25 °C), this is hidden on the display. The uncompensated conductivity at the current temperature is displayed on the right.

If the temperature of the medium exceeded T2 (73.0 °C), the instrument determines the temperature coefficient.

The LC display now shows the determined temperature coefficient as %/K.

✱ Use the key to accept the temperature coefficient or

the key to reject it.

The transmitter is in "measuring mode" and displays the compensated conductivity of the solution.

8 Calibrating a conductivity sensor

PGM

The currently measured conductivity can be coerced manually by pressing the

key. This may be useful if the reference or working temperature cannot be reached precisely. However, the calibration result incorporates a certain amount of inaccuracy!

8.4 Calibrating the relative cell constant

✱ Make preparations, see chapter 8.2 "General information", page 47. ✱ Start calibration, see chapter 8.2.3 "Ways to start the calibration", page 48. ✱ Select the relative cell constant.

✱ Immerse the conductivity sensor in a reference solution with a known

conductivity.

The measurement solution must maintain a constant temperature during calibration! The conductivity sensor must be kept at a distance of at least 20 mm from the container wall during the calibration and must not be moved!

The current measurement value and the temperature are displayed.

✱ When the measurement value is steady, press the key;

the conductivity measurement flashes in the display.

✱ Set the value to the actual conductivity. ✱ Press the PGM key. The relative cell constant determined by the instrument

is displayed (as a %).

9 Calibrating a sensor with a standard signal

9.1 General information

During calibration, relays and analog output signals adopt their configured states!

Sensors with a standard signal output can only be connected to an "Analog input (universal)" optional board!

The sensors connected to the instrument should be cleaned and the instrument itself calibrated, at regular intervals (subject to the sample medium).

Every successfully completed calibration is documented in the calibration logbook, see chapter 10 "Calibration logbook", page 73.

9.1.1 Operating modes

The operating mode selection depends on which sensor (transmitter) is connected.

Linear operating mode

For example sensor for free chlorine, redox, pressure, liquid level or humidity

pH operating mode

For example pH sensor

Conductivity operating mode

For example sensor for conductivity, concentration

Customer specs.

For sensors with non-linear characteristics. Up to xx interpolation points can be defined in an instrument table. This allows for an excellent approximation of a non-linear characteristic.

Chlorine, pH and temperature-compensated

Combination of chlorine sensor and pH sensor and temperature sensor. The measured value for chlorine often depends to a great extent on the pH value of the solution. The chlorine measurement is compensated depending on the pH value in this operating mode. The pH measurement is temperature-compensated

Relative cell constant

Mechanical or chemical effects can change the electrical properties of a conductivity sensor. This will result in a measurement error. This deviation (and thus the measurement error as well) can be compensated for by adjusting the relative cell constant in the transmitter. The relative cell constant defines the deviation of the actual cell constant of the conductivity sensor from its nominal value.

Zero point (1-point) calibration

With one-point offset calibration, the zero point of the pH combination electrode is calculated, see chapter 8.4 "Calibrating the relative cell constant", page 51. Recommended only for special applications, such as ultra-pure water.

2-point calibration

With two-point calibration, the zero point and slope of the combination electrode are calibrated. This is the recommended calibration for most sensors.

Temperature compensation (conductivity or resistance)

The conductivity of a measurement solution is temperature-dependent (the conductivity of a solution rises as the temperature increases). The dependency of conductivity and temperature describes the temperature coefficient of the measurement solution. As conductivity is not always measured for the reference temperature, automatic temperature compensation is integrated in this instrument. The transmitter uses the temperature coefficient to calculate

16 Appendix

the conductivity that would exist for a reference temperature from the current conductivity and the current temperature. This is then displayed. This process is called temperature compensation. Modern transmitters offer different ways to perform this temperature compensation.

- Linear compensation (constant temperature coefficient). This type of compensation can be applied to many kinds of normal water, with acceptable accuracy. The temperature coefficient used is then approx.

2.2 %/°C

- Natural water (EN27888 or ISO 7888). In this case, so-called non-linear temperature compensation is used. According to the standard cited above, the relevant type of compensation can be applied to natural groundwater, spring water and surface water. The definition range for the water temperature is as follows: 0°C ≤ T < 36 °C Conductivity of the water is compensated in the range from 0 °C to 36 °C.

- ASTM1125-95. This type of temperature compensation is used in measurements of ultrapure water. The highly non-linear nature of the temperature dependency for neutral, acidic and alkaline impurities is taken into consideration in accordance with the standard. The definition range for the water temperature is as follows: 0 °C < T < 100 °C. Conductivity of the water is compensated in the range from 0 °C to 100 °C.

Temperature compensation (pH or ammonia)

The pH value of a measurement solution depends on the temperature. Since the pH value is not always measured at the reference temperature, the instrument is able to perform a temperature compensation.

The sensor signal for the ammonia measurement is temperature-dependent. The instrument can perform temperature compensation.

The redox potential of a measurement solution is not temperature-dependent! Temperature compensation is not required.

to the control deviation. When the proportional range is exceeded, the controller operates with an output level of 100 % (100 % clock ratio).

Pulse frequency controller (output active with x > w and P control structure)

If actual value x exceeds setpoint W, the P controller will control in proportion to the control deviation. When the proportional range is exceeded, the controller operates with an output level of 100 % (maximum switching frequency).

Special controller functions: Separate controllers

This function is normally deactivated (factory setting or select "No"). In the deactivated state, the software prevents the two controller outputs from

being able to work "against each other". So, for example, it is not possible to dose acid and lye at the same time.

If the controllers are separate ("Yes" selection), each controller can be freely configured.

Switch-off of the I-component

This function is normally deactivated (factory setting or select "No"). In the deactivated state, the controller works in accordance with general

controller theory. When I-component switch-off is activated ("Yes" selection), the part of the

output level that can be traced back to the I-component is set to zero when the setpoint is reached.

This can be useful with mutual neutralization (acid and lye dosing both possible) in one treatment tank.

Calibration timer

The calibration timer indicates (on request) a required routine calibration. The calibration timer is activated by entering the number of days that must expire before there is a scheduled re-calibration (specified by the system or the operator).

Wash timer

The wash timer can be used to implement automated sensor cleaning. To do this, the function is assigned to a switching output.

16 Appendix

The cycle time (cleaning interval) can be adjusted in the range from 0.0 to

240.0 hours.

A cycle time of "0.0" means the wash timer is deactivated. The wash time (cleaning duration) is adjustable from 1 to 1800 seconds. During the wash time the controller goes into the HOLD state, which is

maintained for 10 seconds after completion of the wash time. A sensor calibration within the cycle time restarts the wash timer.

USP contact (for ultra-pure water)

The USP contact makes it possible to monitor the quality of ultra-pure water according to the requirements of USP <645>. USP <645> contains a table that assigns a limit value for conductivity depending on the temperature. If the conductivity stays below this limit value, the ultra-pure water meets the requirements of USP <645>.

If the conductivity of the water is greater than what is specified in the USP table for a given temperature, the USP contact switches the instrument.

Limit values are defined in levels. For example, a value of 5 °C is used at 8 °C.

Note:

During monitoring, temperature compensation must be turned off (temperature coefficient = 0)! To do this, select Administrator Level/Basic Setting/ Temperature Compensation/None.

USP warning alarm

µS/cm (uncompensated)

If the conductivity is exceeded at the relevant temperature, the configured contact switches.

The USP warning alarm switches before the water quality reaches the set limit value. This parameter (0 to 100) is used to set the distance as a percentage (relative to the active limit value) to be maintained from the USP limit.
