3 Application
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 pHJUMO type 202701
- for redox voltageJUMO type 202702
- for conductivityJUMO 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 oxygenJUMO dTRANS O2 01
- for free chlorine, chlorine dioxide and ozoneJUMO 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.

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

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.
2-point calibration makes a fresh determination of the
slope
using two buffer solutions.
electrode zero and
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.

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

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.

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 periodCYThis 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 timertIntegral 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 1SP(r)1The 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
