4 Mounting
5 Electrical connection
The choice of cable, the installation, and the electrical connection
must conform to the requirements of VDE 0100 “Regulations on the
Installation of High-Voltage Systems with Nominal Voltages below
1000 V” or the appropriate local regulations.
❏To protect the device from static electrical discharge, the user
must be electrostatically discharged before touching the
instrument!
❏The electrical connection must only be carried out by qualified
personnel.
❏Electromagnetic compatibility conforms to the standards and
regulations cited in the technical data.
❏Operates only on SELV or PELV circuits.
❏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. Safety devices should always be provided that are
independent of the instrument (such as overpressure valves or
≤ 75
-10
+60
°C

10
temperature monitors/limiters) and only capable of adjustment by
specialist personnel. Please observe the relevant safety regulations
for such matters.
❏The load circuit must be fused for the maximum relay current, in
order to prevent the output relay contacts from becoming
welded in the event of a short circuit.
❏The supply voltage must be fed into the instrument through a
125-mA fuse, medium time lag or comparable protection by
means of a separate branch.
❏Do not connect any additional loads to the screw terminals for
the supply of the instrument.
❏Any electrical connection deviating from the connection diagram
may cause the instrument to be destroyed.
❏Lay the input, output, and supply lines so they are physically
separated from each other and are not parallel.
❏Lay probe cables only as continuous lines, twisted and shielded
(not via series terminals or similar arrangements).
❏Fluctuations in supply voltages are only permitted within
specified tolerances (see datasheet 20.2723).
❏The instrument must not be mounted or dismounted unless it is
in dead state and/or the lines are not connected.
5.1 Connecting the sensor
To connect the pH redox electrode, special coaxial lines are
recommended as specified by JUMO datasheet 202990. Standard
commercial antenna or computer lines with coaxial construction are
generally not suitable. They may result in faulty readings or could
destroy the pH or redox electrode.
The semiconducting layer (see Fig. (2)) of the special coaxial line must
be at a sufficient distance to prevent a short circuit with the inner
conductor on the transmitter terminal. The coaxial line may be sensitive
to touch or motion due to the high internal resistance of a pH electrode.
This must be taken into consideration when laying the cable.

11
5.2 Customizing the special coaxial line
Example:
✱Strip insulation from the line as shown in the drawing. Remove
the black semiconducting layer (2) from the insulation of the inner
conductor as indicated.
✱Twist the shield (1) and insulate with a shrink tubing.
✱Insulate the black semiconducting layer with shrink tubing (2) to
prevent short circuits.
✱Place ferrules on the line ends.

6 Commissioning
6.1 Brief description of the instrument
The instrument measures and, depending on the configuration,
regulates the pH or redox voltage in aqueous solutions. The range
of applications includes general water and wastewater
management, measuring drinking and wastewater, process water,
surface and ocean water, swimming pool and fountain water, and
professional aquariums, etc.
The transmitter has two analog inputs. The first analog input (main
input for pH value or redox voltage) is provided for connecting
electrodes with an isolated reference electrode. The instrument is
also prepared for connecting antimony electrodes. A resistance
thermometer (Pt 100 or Pt 1000) can be connected to the second
analog input.
Up to two analog outputs and one relay switching contact are
available. The analog outputs are galvanically isolated and assigned
to the inputs. Either the main value (pH or redox voltage) or the
temperature can be assigned to the relay contact.
The keys and integrated LD display are used to operate and
configure the instrument. This can also be done very conveniently
with the setup connection (Notebook / PC) using the optional setup
program. The setup program can also be used to print configuration
data. This makes system documentation easier.
Instruments are delivered with a calibration verification tool that is
used to document instrument and calibration data.
With the correct wiring of device and sensor, and
correct configuration of the device, a measure-
ment without calibration should be possible.
If this is not the case, influencing factors such as
short circuit, open circuit, EMC and flow conditi-
ons should also be considered.

6.3 Applying the supply voltage
If the instrument has been correctly connected, all LCD segments are
briefly lit immediately after the supply voltage is applied.
Note:
After the instrument is started, the output signal is 0 V or 0 mA. The
relay is in idle state (inactive). After about 2 seconds, the JUMO
ecoTRANS pH 03 begins working according to the configuration.

7.2 Operation
The instrument can be operated on different levels.
Access to all levels (except the user level) is protected by different
codes2.
On the User level (USER) all parameters can be viewed and/or
modified depending on user rights1(see Enable level).
On the Calibration level (CALIB) the electrode zero point (intercept
point) and/or the electrode slope can be calibrated.
On the Enable level (RIGHT) user rights can be defined.
On the Administrator level (ADMIN) all parameters can be set
(configured).
The different codes and settings on the Enable level make it
possible to assign different user rights to users.
1The factory setting for all parameters is "READ," i.e. all
parameters can only be read on the User level, not changed.
2Codes for the Administrator and Enable levels can only be
changed with the setup program
(see Section 13 "Operation via setup interface", page 64).
7.3 Key function
- The UP and DOWN keys are used to select a submenu in the
main menu and to scroll forward and backward.
- The P key switches to the corresponding submenu.
- To change (edit) a parameter, press the P key.
- When the parameter is released for editing, the value flashes. If
the parameter is locked, "LOCK" appears in the display.
- To change the parameter, it must be unlocked on the Enable level
(changed from "rEAd" to "Edit").
After 60 seconds with no user activity (no keystrokes),
the display reverts to process value display.
This timeout function is not active during calibration!

19
- To increase or reduce the value, press the UP or DOWN key.
- The value can then be accepted with the P key.
- The EXIT key is used to cancel the entry and switch to the next
higher level.
