Product identification
It is very important for the overall measuring accuracy that
the pressure transmitter has the correct pressure range.
Check that the item(s) delivered corresponds to the
ordered item (s) by means of the information on the label
on the packing:
On the model 3400 transmitters, the pressure ranges together with the corresponding part numbers are printed
on a label on the transmitter housing.
For all versions the pressure range is indicated on the
label.

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 Expert 1400 or 3400 level transmitter
must be strictly observed.
2: The use of an approved zener barrier or isolator is
mandatory when installing Expert™ Level Transmitter
1400 and 3400 in explosion hazardous areas.
Repair
1: Repair of EX approved equipment must only be made
by MJK or by a service representative approved by MJK.

Mechanical mounting
Model 1400
1: Mount a suitable hook over the desired measuring
location. Note the weight of the cable.
2: Remove the inner conical sleeve from the cable fitting
and pull the cable through the outer part. Open the inner
sleeve and fit it around the cable at the desired fixation
point and press the inner sleeve into place in the outer
part. Secure the cable fitting by pulling the
cable downwards.
3: Lower the pressure transmitter into the wellpipe.
Take care not to hit the bottom hard since it may damage
the transmitter!
Model 3400
1: Mount a suitable hook over the desired measuring
location. Note the weight of the cable.
2: Mount the cable fitting onto the cable. Open the fitting
by sliding the two plastic jaws upwards, place the cable
between the jaws and slide the jaws downwards until the
cable locks. Secure the cable fitting by pulling the
cable downwards.
3: Lower the pressure transmitter into the liquid.
Take care not to hit the bottom hard since it may damage
the transmitter!
4: If the 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 transmitter from bumping into the wall or
other components.
It is very important that minimum 25 mm of the pressure
transmitter is not being covered by the pipe!

Cable length vs. supply voltage
The cable can be lengthened with any type of cable
using connection box 202922. Although the measuring
signal is not sensitive to electrical noise, we recommend
the use of a screened cable.
Ensure that no moisture can enter the pressure compensation tube inside the cable.
The length of the cable is only limited by the total resistance (A) of the cable conductors + the input impedance
of the analog input on the MJK 704, MJK 713, PLC etc.
(typically 10 to 100 Ω) and the available supply voltage
(B) (typically 24 V DC).
Example:
The nominal resistance for 1 conductor in a transmitter
cable is 0,036 Ω /m. A standard 12 m cable will therefore
add 2 x 0,036 x 12 = 0,86 Ω to the loop resistance. If the
analog input has an impedance of 50 Ω., the total
resistance will be approx. 51 Ω.
Necessary supply voltage in relation to the total loop resistance.
(A) Total loop resistance [ Ω]
Designation of wires, cutting & stripping the cable
The factory delivered cable has the wires marked with
the numbers 1 - 2 - 3 as to the table to the right. If the
cable needs to be cutted 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 off in different lengths to prevent
them from short circuit.
Take care not to block or squeeze the air pressure
compensation tube ➄.
Designations:
1: Positive (+) wire, red
2: Negative (-) wire, brown

Isolator
The KFD0-CS-Ex1.50P isolator (MJK part no.: 202993) which supplies the pressure transmitter through a galvanic separator so neither current nor voltage exceeds the specified limits.
Zener barrier
The Z788 Zener Barrier ( MJK part no. 202995) has a safety fuse which will blow if the current exceeds the limit.
The voltage protection in the Zener barrier contains a number of zener diodes, which are connected from each signal
cable to ground.

Demands for cables in explosive areas
Using the the KFD0-CS-Ex1.50P isolator (MJK order
no.: 202993) the max cable length can be calculated.
The Cmax and Lmax for the isolator in explosion group
IIC are: Cmax : 2,41 μF, Lmax : 4 mH. The capacity of
MJK cable type 691005 or 691014 < 800 pF/m and
the inductance is < 1,5 μH/m and the capacity and the
inductance of the Expert Level Transmitter is Ci = 3,5 nF
Li = 7 μH. Cable length based on the capacity:
Max.cable length = (Cmax-Ci)/Ccable = 129 m
Cable length based of the inductance:
Max. cable length = (Lmax-Li)/Lcable = 2862 m
In this case the capacitance sets the limit of the cable
length to 129 m. If another approved isolator or another
cable is used the max. cable length must be recalculated.
Using The Z788 Zener Barrier (MJK Order no. 202995)
the max cable length can be calculated. The Cmax and
Lmax for the zener barrier in explosion group IIC are:
Cmax : 83 nF, Lmax : 3,05 mH. The capacity of MJK
cable type 691014 is < 800 pF/m and the inductance is
< 1,5 μH/m and the capacity and the inductance of the
Expert Level Transmitter is Ci = 3,5 nF Li = 7 μH.
Cable length based on the capacity:
Max. cable length = (Cmax-Ci)/Ccable = 99 m
Cable length based on the inductance:
Max. cable length = (Lmax-Li)/Lcable = 2,0 km
In this case the capacitance sets the limit of the cable
length to 99 m. If another Atex-approved isolator or
another cable is used the max. cable length must
be recalulated.
