A sudden malfunction of the instrument, or one of the sensors connected to it,
could potentially result in dangerous, overdosing! Suitable preventive measures
must be in place to prevent this from happening.
Note:
Please read these Operating Instructions before placing the instrument in
operation. Keep the manual in a place which is accessible to all users at all times.

Power supply
for a 2-wire transmitter
Inputs/outputsIn addition to the main input (pH/redox) and the secondary input (temperature
compensation), the basic device alone has two binary inputs, two relays, one
voltage 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.
OptionalThree further slots can be fitted with extensive additional configurable inputs
and outputs and interfaces.
ApplicationThe device is suitable, for example, for displaying, measuring and controlling:
- pH value and/or redox potential.
- 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 or
406020.
- 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.

5.1Installation 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 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
device.
• The device is not suitable for installation in areas with an explosion hazard.
• Apart from faulty installation, incorrect settings on the device 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 device and it should only be possible for qualified personnel to make
settings.

8 Calibrating a pH measurement chain
8.1Notes
During calibration, relays and analog output signals adopt their configured
states!
When is calibration required?
- At regular intervals (depending on the sample medium and requirements).
- If negative values appear in the top display.
- If the top display indicates "Underrange/Overrange".
Every successfully completed calibration is documented in the calibration
logbook, see chapter 12 "Calibration logbook", page 88.
8.2General 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 causes
the output signal of the sensor to change.
The transmitter uses a typical, concentration-dependent characteristic to
measure ammonia with "normal" accuracy requirements. The individual
properties of the sensor are taken into account here by offsetting the zero
point. This considerably reduces the effort required for calibration.
The transmitter software is specially adapted for coolant monitoring.
8.2.1Requirements
- The device must be supplied with voltage, see chapter 5 "Installation",
page 13 ff.
- A combination electrode must be connected to the transmitter.
For a configuration example see chapter 7.2.1 "Measuring the pH value with
pH combination electrode", page 43.
A pH sensor can be connected to the optional board
- connected directly to the main input or
- connected to the "Analog input (universal)" optional board via a 2-wire
transmitter.
- "PH STANDARD" must be configured as sensor in the basic setting.
- The device is in Measurement mode.

8.2.3Calibration options
The device provides two calibration options for adapting the JUMO dTRANS
02 pH to a pH combination electrode:
One-point offset calibration
The zero point of the pH combination electrode is calibrated, see chapter 8.3
"Zero point (1-point) calibration", page 53.
Recommended only for special applications, such as ultra-pure water.
Two-point calibration
The zero point and slope of the combination electrode are calibrated, see
chapter 8.4 "2-point calibration", page 54.
This is the recommended calibration for most sensors.
Three-point calibration
In three-point calibration, the zero point and the slope are calibrated in the
acidic range and the slope is calibrated in the alkaline range, see chapter 8.4
"2-point calibration", page 54.
This calibration is recommended with heightened requirements for accuracy.

During calibration, relays and analog output signals adopt their configured
states!
Sensors with a standard signal output can only be connected to an "Analog

The sensors connected to the device should be cleaned and the device itself

Every successfully completed calibration is documented in the calibration
logbook, see chapter 12 "Calibration logbook", page 88.
11.1.1 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 20 interpolation points can be defined in an device 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

13.1General information
Apart from faulty installation, incorrect settings on the device 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
device and it should only be possible for qualified personnel to make settings.
13.2Controller functions
"Software" control functions are assigned to "Hardware" outputs for this
device.
1 Software controller for "simple" switching functions (e.g. alarm control)
2 Software controller for "higher order" switching functions (e.g. PID
If "higher order controller functions" have been configured, both the digital
outputs and the analog outputs can be controlled.
The operator must configure which of the outputs will be controlled - the main
board or optional board 1, 2 or 3.
