3.1 Type 202550

Description

Inputs

Calibration procedure

The compact microprocessor indicator/controller, with 96mm x 48mm bezel and plug-in controller module visualizes and controls variables in analytical measurement (pH value, redox voltage, conductivity, chlorine, chlorine dioxide, ozone and mA).
The indicator has two analog and two logic inputs. The first analog input is suitable for connecting a 0(4)— 20 mA signal, which can be provided by any type of transmitter (including 2-wire types). The input signal is conditioned as determined by the configuration, and displayed. The second analog input can be used to connect Pt100 or Pt1000 resistance thermometers.
One special feature of the instrument is that the calibration procedures for pH, redox and conductivity are internally programmed. This permits the connection of simple transmitters (without their own calibration facilities) to the dTRANS Az 01. In this case, the indicator/controller has to be configured accordingly.
Examples of simple transmitters:
- for pH JUMO type 202701
- for redox voltage JUMO type 202702
- for conductivity JUMO type 202754/xx-xxx/263

Standard signals

Display

Outputs

The dTRANS Az 01 is also suitable for the connection of transmitters that produce a standard output signal. In this case, the dTRANS Az 01 must be configured as a universal indicator.
Examples of JUMO transmitters with standard output signals:
- for dissolved oxygen JUMO dTRANS O2 01
- for free chlorine, chlorine dioxide and ozone JUMO Typ 202630
- JUMO pressure transmitters
The instrument features two 4-digit 7-segment displays for indicating the main variable (red) and the temperature (green). The temperature display is switched off in the default setting. A separate temperature sensor (Pt100 or Pt1000) can be connected to the second analog input. This can then be used to display the temperature of the medium and, if required, monitor it by means of a limit comparator (limit switch). During programming, the displays provide comments on the inputs.
The instrument has a maximum of 5 outputs

6.1 Location

6 Assembly

Conditions

Panel cut-out for close mounting

6.2 Fitting

The location should be as free from vibration as possible. Electromagnetic fields, e. g. from motors, transformers etc. should be avoided. The ambient temperature at the location can be from 0 to 50 °C, with a relative humidity of not more than 75 %.
(1)
Fit the seal (1) that is supplied onto the body of the instrument.
Insert the controller from the front into the panel cut-out.
From behind the panel, slide the mounting brackets into the guides on the sides of the housing. The flat faces of the mounting brackets must lie against the housing.
Push the mounting brackets up to the back of the panel, and tighten them evenly with a screwdriver.
16
6.3 Removing the controller module
The controller module can be removed from its housing for servicing.
Press together the ribbed surfaces at right and left and pull the controller module out of the housing.
6 Assembly

6.4 Cleaning the front panel

The front panel can be cleaned with normal commercial washing, rinsing and cleaning agents.
It has a limited resistance to organic solvents (e.g. methylated spirits, white spirit, P1, xylol etc.).
Do not use high-pressure cleaning equipment!
17

7.1 Electrical connection

The electrical connection may only be carried out by properly 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” or the appropriate local regulations.
The electrical connection may only be carried out by properly qualified personnel.
The instrument must be completely disconnected from the electrical supply if contact with live parts is possible.
A current-limiting resistor interrupts the supply circuit in the event of a short-circuit. Any additional external fusing of the supply should not be rated below 1A (slow).
The load must be fused for the maximum relay current, in order to prevent the contacts of the output relay becoming welded in the event of a short­circuit.
The level of electromagnetic compatibility conforms to EN 61 326.
Run input, output and supply cables separately, not parallel to one another.
Sensor and interface cables should be shielded cables with twisted conductors. Do not run them close to current-carrying components or cables. Ground shielding at one end, to the TE terminal on the instrument.
The TE terminal on the instrument must be earthed. This lead must have at least the same conductor cross-section as that used for the supply cables. Grounding and earthing leads must be wired in a star configuration to a common earth point that is connected to the protective earth of the electrical supply. Do not loop earth or ground connections, i.e. do not run them from one instrument to another.
Do not connect any additional loads to the supply terminals of the instrument.
The instrument is not suitable for use in areas with an explosion hazard (Ex areas).
In addition to faulty installation, incorrect settings on the controller (setpoint, data of the parameter and configuration levels, internal alterations) can also interfere with the correct operation of dependent processes, or even cause damage. The stability of the actual value that is produced should therefore be checked. Safety devices should always be provided that are independent of the controller (such as overpressure valves or temperature monitors/limiters) and only capable of adjustment by specialist personnel. Please observe the relevant safety regulations for such matters.
The measurement inputs of the controller must not exceed a maximum potential of 30 V AC or 50 V DC against TE.
Sensor leads should only be implemented as uninterrupted cables
not
(
routed through terminal strips etc.).

7 Installation

18
After the supply voltage has been applied, the instrument will operate according to the factory-set parameters (unless the instrument was ordered with “controller off”).
It is therefore advisable to program the instrument as required
before connecting the actuators

the instrument performs a self-test, during which all displays will light up.
If the self-test was OK, then the instrument switches over to the measurement mode in about 10 seconds.
The measured current signal (proportional to the measured value) is displayed, as is the measured temperature (if the temperature sensor has been connected and configured); the controller operates according to the factory­set parameters!
In measurement mode, manual operation, hold, and calibration can be activated, as well as the display of the software revision level and the dimensional unit (°C /°F) for the temperature input.

10 pH indicator

10.1 pH measurement circuit

The JUMO dTRANS Az 01 indicator/controller (1) requires a standard input signal (0(4) — 20 mA) that is proportional to the pH.
The 2-wire pH transmitter (2) provides this standard signal. The pH combination electrode (3) is connected to the 2-wire pH transmitter (2),
which in its turn is connected to the JUMO dTRANS Az 01 (1). A temperature probe (4) can be connected to the indicator/controller as an option. This temperature probe can be used to measure the temperature of the liquid. The dTRANS Az 01 can indicate this temperature, control it, and/or use it for temperature compensation of the pH value.
As a further option, the JUMO dTRANS Az can supply the voltage for the 2­wire transmitter.

The electrode parameters of a pH combination electrode are subject to manufacturing tolerances and variations depending on usage. To compensate for these changing electrode parameters, the indicator/controller offers two calibration procedures:

In 1-point calibration,
only the electrode zero
is freshly determined using a buffer solution (solution with a known pH value). Problems arising from an incorrect electrode slope will not be detected by the user! This method should only be adopted in cases where the electrode is not subject to significant chemical and mechanical influences.

slope
using two buffer solutions.

This method should be given preference!
In addition to the calibration procedure described above, the indicator/
controller offers the facility of manually entering the zero point and slope (as
determined by a laboratory, for example).
The measurement of the pH value depends on temperature; the temperature of the solution to be measured must therefore be known for calibration. The temperature can either be measured automatically, with a Pt100 or Pt1000 temperature probe, or set manually by the user.

The delivery condition of the electrode is such that generally no calibration of the transmitter for the electrode parameters is required. Through usage, however, the electrode parameters may change. To compensate for this, the indicator/controller can be adjusted to the zero point of the electrode. If a new electrode is connected to an indicator/controller that has already been

18.6 Calibration

The cell constants of conductivity cells vary somewhat from one example to another, and also drift with use (because of deposits and wear). This results in a change of the output signal from the cell. It is therefore necessary that the user is able to compensate for the deviations of the cell constant from the nominal value, either by manual input or an automatic calibration of the relative cell constant K
Chapter 18.7 “Calibrating the relative cell constant”, page 53 The time interval between two calibrations depends on the conditions in which the cell is used.
The conductivity of a solution varies with the temperature, so for correct measurement both the temperature and the temperature coefficient of the solution being measured must be known. The temperature can either be measured automatically, with a Pt100 or Pt1000 temperature probe, or set manually by the user. The temperature coefficient can be determined automatically by the JUMO dTRANS Az 01, or entered manually. .

22.1 Measurement circuit for the universal indicator

The JUMO dTRANS Az 01 (1) indicator/controller requires a standard 0(4) — 20 mA input signal that is proportional to the conductivity.
The JUMO transmitter for free chlorine, type 202630 (2) provides such a standard signal. A optional temperature probe (3) makes it possible to display or control the temperature of the substance being measured.
As an option, the JUMO dTRANS Az can provide the supply voltage for the JUMO transmitter for free chlorine, type 202630.

22.3 Calibration

It may be necessary to match the display to the values, depending on the probe or transmitter that is being used. For this reason, when configured as a universal indicator, the dTRANS Az 01 provides calibration procedures to suit a wide range of requirements.

1-point calibration Zero point

1-point calibration End value

2-point calibration

Manual entry

The zero point is determined here, or an offset adjustment is made.
A single end value adjustment is made.
With 2-point calibration, the start and end values can be freely defined.
In addition to the calibration procedure described above, the indicator/
controller offers the facility of manually entering the zero point and the slope,

whether the process value output is frozen or not during calibration.
Chapter 21.2 “Analog inputs - C111”, page 61.
If subsequent calibrations are carried out with the same settings, then it will not be necessary to set them again.
“Freezing” the process value output means that, during calibration, the output signal is held at the value that was produced immediately before calibration started. This is to avoid an uncontrolled reaction from any PLC that may be connected to the output of the indicator/ controller.
While the process value output is frozen, the lower display shows “donE” after the last calibration step, and the upper display shows the latest measurement. The process value output remains unchanged!
After the chlorine cell has been installed once more, the key must be

pressed. The process value output is now coupled to the display again.
The factory setting is: “Calibration without frozen process value output”.

Press the key repeatedly, until “C211” appears in the lower display.

27.2 Controller optimization

27 Controller

Optimum adjustment

The optimum adaptation of the controller to the control loop can be tested by recording the starting phase.
The following diagrams (referred to the PID action) indicate where the adjustments may be incorrect, and how they can be rectified.
It can be seen that a slower control action with higher stability can be achieved by increasing either the proportional band Pb or the reset time rt.
A smaller proportional band Pb and / or a shorter reset time rt will result in a control action with less damping.

GSD generator

The Profibus-DP interface can be used to integrate the controller into a fieldbus system operating according to the Profibus-DP standard. This Profibus version is especially designed for communication between automation systems and decentralized peripheral devices at the field level, and optimized for speed.
The data transmission is made serially, using the RS485 standard.
GSD generator, the project-planning tool that is supplied with the package (GSD = Gerätestammdaten, i.e. basic device data), is used to make a selection of device characteristics for the controller to create a standardized GSD file that is used to integrate the controller into the fieldbus system.

Proportional band
Proportional controller
Pulse contact / steady contact
Pb The range over which the output signal from a pulse width or
pulse frequency controller is proportional to the control deviation. Beyond the proportional band, the controller will output the signal defined by the
C211 C213 C214
C213 The behavior of an alarm contact.
In a proportional controller there is a continuous signal (i.e. a current or voltage) on the output. This signal can take on any intermediate value between a start value and an end value. Depending on the configuration of the instrument, this continuous signal can be in the range 0 — 10 V, 0 — 20 mA or 4 — 20 mA.
Proportional controllers are used, for example, to operate actuator valves.
Pulse contact: The alarm output remains active for approx. 1 second, even if the switching condition (cause) of the alarm remains present for a longer time.
The LED (for the output that was defined as the alarm output) blinks until the switching condition (the cause) of the alarm is no longer present.
Steady contact: The alarm output remains active until the switching condition (the cause) of the alarm is no longer present.
The LED blinks for the output that was defined as the alarm output.

Pulse period CY This value is the period within which the pulse width modulation
occurs (only for a pulse width or modulating controller). The value is limited by the Pulse period [sec]> minimum ON time [sec])
Reset time rt Integral time constant – controller parameter in a PI or PID
controller. The value determines the speed at which the control deviation is integrated. If the reset time is set to “0”, then the control action has no integral component.
Setpoint 1 SP(r)1 The given value that should be achieved by the control loop
(referring to output K1). The setpoint pair that is fed to the controller is identified in the
parameter display by (r). See also Example
for the active setpoint pair 1 => SPr1, SPr2 and SP 3, SP 4.
for the active setpoint pair 2 => SP 1, SP 2 and SPr3, SPr4. Setpoint 2 SP(r)2 As for Setpoint 3 SP(r)3 Refers to output K1. For explanation see
