2 Description

Inputs/outputs In addition to the main input (conductivity, TDS, resistance) and the secondary

input (temperature compensation), the basic instrument alone has two binary inputs, two relays, one power supply for external sensors and a setup interface.

Input signals can be shown as numbers or as a bar graph on the graphic display. Parameters are displayed in plain text for easily comprehensible and reliable operation.

Optional Three further slots can be fitted with extensive additional configurable inputs

and outputs and interfaces.

Application The instrument is suitable, for example, for displaying, measuring and

controlling:

- Conductivity, TDS and resistance.

- Free chlorine, chlorine dioxide, ozone, hydrogen peroxide and peracetic acid, in combination with sensors as per data sheet 202630.

- (Hydrostatic) liquid levels with 2-wire transmitters (level probes) as per data sheet 402090 or data sheet 404390.

- Flow rate in conjunction with transmitters as per data sheet 406010.

- Two temperature measuring points.

- Most sensors and transmitters that output standard signals (0 to 10 V or 0(4) to 20 mA).

Because temperature measurement is integrated, temperature compensation takes place quickly and precisely, which is particularly important for many analytical measurements.

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 instrument 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.

8.1 Notes

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

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 section 9 "Calibration logbook", page 66.

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.

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.

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 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).

- Natural water (EN27888 or ISO 7888).

- ASTM1125-95.

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

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.

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 with the temp. coef. curve

The relevant temperature coefficient is determined from the temp. coef. curve by means of the current temperature of the medium.

Intermediate values, such as (α

) and (α4 at T4) are linearly approximated.

at T

As with linear temperature compensation, the compensated measurement value is calculated with the ascertained TC.

If the measured temperature is lower than the temperature at the beginning, the first TC is used for compensation. If the measured temperature is higher than the temperature at the end, the last TC is used for compensation.

at Tx) between the two ascertained values (α3

Page 92

15 Appendix

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.

Concentration measurement

The instrument can calculate the concentration of different measuring materials from the current measurement values of uncompensated conductivity and temperature.

Choice of concentration calculations:

NaOH (caustic soda)

- Range 1: 0 to 12 % by weight

- Range 2: 25 to 50 % by weight

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.

Page 95

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.

The value is also used in evaluating drinking water quality (for example in the USA, Arab and Asian countries). Various organizations have published limit values on this topic.

is sufficient to determine the conversion factor. It corresponds to the ratio of the conductivity value of the water to the value of the gravimetrically determined filtrate dry residue (TDS). The factor moves within the range from

0.55 to 1.0. A typical value for drinking water is about 0.67. With modern instruments, this factor can be entered individually to achieve the

most accurate measurement possible.

Recording duration = about 10 hours with a storage interval of 1 second Recording duration = about 150 days with a storage interval of 300 seconds

Parameter set switchover

In some processes (different process steps) is is advantageous to have two complete parameter sets available.

Define the parameter sets See section 10.5 "Parameter sets", page 70. The predefined parameter sets are activated by a binary input.
