1 Notes
All necessary settings are described in this Operating
Manual. However, if any difficulties should still arise
during start-up, please do not carry out any
manipulations on the unit. You could endanger your
rights under the instrument warranty! Please contact
the nearest subsidiary or the head office in such a
case.
Please read this operating manual before starting up
the instrument. Keep the manual in a place which is
accessible to all users at all times. Please assist us to
improve this operating manual, where necessary.

3 Installation
4 Electrical connection
The choice of cable, the installation, the fusing 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 must only be carried out by qualified
personnel.
❏Electromagnetic compatibility conforms to the standards and
regulations cited in the technical data.
❏The instrument is not suitable for use in areas with an explosion
hazard (Ex areas).
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
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 becoming welded in
the event of a short circuit.
❏Do not connect any additional loads to the screw terminals for
the supply of the instrument.
❏Any electrical connection other than that specified in the
connection diagram may result in the destruction of the
instrument.
❏Run input, output and supply cables separately and not parallel
to one another.
❏Probe leads must be implemented as twisted and shielded,
uninterrupted cables (do not run them via terminal blocks or
similar).
❏Supply fluctuations are only permissible within the specified
tolerances (see Data Sheet 20.2732).
❏The instrument must only be assembled or disassembled in the
de-energized state or when the cables are not connected.

5 Commissioning
5.1 Fundamentals of conductivity measurement
Principle of measurement
Electrolytic conductivity measuring cells basically consist of two
metal plates arranged opposite each other which are immersed in the
solution to be measured. The conductivity of the solution is
determined through the measuring voltage and the resulting
measuring current.
The current between the metal plates depends on their geometry
(distance and area). The
cell constant describes this dependence.
Subject to manufacturing tolerances, or because of dirt or wear, the
real cell constant of a measuring cell often deviates from its nominal
value. This deviation is reflected by the
relative cell constant that is
adjustable on the conductivity transmitter.
The conductivity of a solution depends on temperature (i.e. the
conductivity of a solution increases with rising temperature). The
temperature coefficient of the solution describes the dependence
of conductivity and temperature. Since conductivity is not always
measured at the reference temperature, automatic temperature
compensation has been integrated. The transmitter uses the
temperature coefficient to calculate the conductivity that would be
present at the reference temperature from the current conductivity
and the current temperature, and then display this value.
5.2 Applying the supply voltage
When the instrument has been correctly connected, all LCD
segments will be shown briefly, immediately after applying the supply
voltage.
Note
After initializing the controller, the output signal is 0 V or 0 mA. The
logic outputs or relays are in the quiescent state (inactive). After
approx. 2 sec, the JUMO ecoTRANS Lf 03 operates according to its
configuration.

6 Setting / altering the instrument functions
Alterations can be carried out in the setup program or from the keys
of the JUMO ecoTRANS Lf 03.

6.2 Operation
The operation of the instrument is arranged on levels.
The access to all levels (exception: operator level) is protected by
different codes2.
At the operator level (USER), all parameters can be viewed or
altered in accordance with the user rights1(see enabling level).
At the calibration level (CALIB), the cell constant and/or
temperature coefficient can be calibrated.
At the enabling level (RIGHT), the user rights can be defined.
At the administrator level (ADMIN), all parameters can be set
(configured).
The different codes and the settings at the enabling level make it
possible to assign different rights to the user.
1In the factory default setting, all parameters are set to READ,
which means that all parameters can only be read at the operator
level but not altered.
2The codes for the administrator and enabling levels can only be
altered through the setup program,
see Chapter 13 “Operation via setup interface”, page 61.
6.3 Function of keys
- Use the UP and DOWN keys to select a submenu in the main
menu or to scroll forwards or backwards.
- Use the P key to change to the corresponding submenu.
- If you want to alter (edit) a parameter, press the P key.
- If the parameter has been enabled for editing, the value flashes, if
the parameter is inhibited, LOCK is displayed.
After 60 seconds without operator action (key stroke)
the instrument jumps back to displaying the actual
value.
This time-out function is inactive during calibration!

15
- In order to alter a parameter, it must be enabled at the enabling
level (set from “rEAd” to “Edit”).
- Press the UP or DOWN key to increase or decrease the value.
- Accept the value by pressing the P key.
- Use the EXIT key to cancel the entry and change to the next-
higher level.
