Specific conditions for use
• Before taking into use, the user shall make an evaluation of the compatibility between proces s media
and the materials in the 1400 or 3400 Expert
• The equipment must be connected via an approved or cer tified inter face/zener barrier placed out
side the hazardous area.
• For ins tallations in which both the Ci and Li of the connected apparatus exceeds 1% of the Co and Lo
parameters (excluding the cable), then 50% of Co and Lo parameters are applicable and shall not be
exceeded.
• For model 3400 Expert
possibility of electrostatic discharge.
The maximum length of the cable is c alculated from the Expert pressure transmitters internal capacity
(3,5 nF) and internal self-induction (7 μH). The cable capacity (MJK 0,8nF/m) and the self-induction (MJK
1.5 μH/m) is added.
The 2 values are added to calculate the total capacit y and the total self-induction. The Ex isolator or
Zener barrier is marked with the maximum capacity and self-induction for the connection. These two
values must never be exceeded.

Introduction
Thank you for choosing ExpertTM Level Transmitter.
We have done everything possible to make an
ExpertTM Level Transmit ter that can fulfil all your
demands.
ExpertTM Level Transmit ter is suitable for all kinds
of level measurements. It can control and supervise
levels i n wells and tanks - including aggressive and
polluted me dia.
The ExpertTM Level Transmit ter is both easy to install and put into service, but read this manual first
- then you will benefit the most from the E xpertTM
Level Transmitter right from the beginning.
You can always cont act your representative or the
MJK Ser vice Hotline for advice and guidance. Also,
take a look at ht tp://www.mjk.com.
ExpertTM Level Transmitter is registered trademark of
MJK.

Safety instructions
1: Read this manual carefully.
2: Be aware of the environment on the installation
site. Wear necessary protective equipment and follow
all current safety regulations.
3: Do not operate the equipment outside the specified electrical, thermal and mechanical parameters
(see datasheet). Ins tall the device only in media for
which the wet ted materials have sufficient durability. (See datasheet for housing material.)
Max. supply voltage is 30 VDC.
4: Do not connec t or use any programming interface/equipment while the ExpertTM Level Transmitter
is located in an explosion hazardous environment.
Hazardous areas
1: All current local and national standards, regula-
tions regarding installation and use of Ex or hazardous zone approved equipment, certifications and
safety instructions for Ex equipment that have been
used together with the installation of the E xper tTM
1400 and 3400 Level Transmitter must be strictly
observed.
2: The use of an approved zener barrier or isolator
is mandatory when installing Expert™ 1400 and
3400 Level Transmitter in explosion hazardous
areas.
Repair
1: Repair of Ex approved equipment must only be
done by MJK or by a service representative approved by MJK.
Mechanical mounting
ExpertTM Level Transmitter model 1400
1: Mount a suitable hook over the desired
measuring location. Note the weight of the
cable.
2: Lower the ExpertTM Level Transmitter
into the liquid.
ExpertTM Level Transmitter model 3400
1: Mount a suitable hook over the desired
measuring location. Note the weight of the
cable.
2: Lower the ExpertTM Level
Transmitter into the liquid.
3: If the ExpertTM Level
Transmitter is to be used in
a wetwell or other locations
with turbulence or other
disturbance, it is advisable to install a pipe (min.
nominal diameter = 75 mm)
to protect the ExpertTM Level
Transmitter from bumping
into the wall or other components.
Take care not to hit the
bottom hard since it may
damage the Exper tTM Level
Transmitter!
It is ver y important that minimum 25 mm of the ExpertTM
Level Transmitter is not
covered by the pipe!

Cable length vs. supply voltage
The cable can be leng thened with any type of
cable1). Although the measuring signal is not sensitive to electric al noise, we recommend the use of a
screened cable.
Ensure that no moisture can enter the pressure
compensation tube inside the cable.
Designation of wires, cutting & stripping the cable
The factory delivered cable has the wires marked
with the numbers 1 - 2 - 3. If the cable needs to
be cut ted and stripped, the shield should be connected as the no. 3 wire.
Do NOT connect any of the colored programming wires as it may damage the transmitter. The
programming wires should be cut of f in different
lengths to prevent them from short circuit2).
Take care not to block or squeeze the air pressure
compensation tube.
