uct can be clearly identified.
FIg. 1 manufacturing label- example
!The manufacturing label must not be removed from the
device!
3. Mechanical installation
3.1 Mounting and safety instructions
WARNING! Install the device only when depressurized
and currentless!
WARNING! This device may only be installed by qualified
technical personnel who has read and understood the op-
erating manual!
!Handle this high-sensitive electronic precision measuring
device with care, both in packed and unpacked condition!
!There are no modifications/changes to be made on the
device.
!Do not throw the package/device!
!To avoid damaging the diaphragm, remove packaging
and protective cap directly before starting assembly. The
delivered protective cap has to be stored!
!Place the protective cap on the pressure port again
immediately after disassembling.
!Handle the unprotected diaphragm very carefully - it is
very sensitive and may be easily damaged.
!Do not use any force when installing the device to prevent
damage of the device and the plant!
!For installations outdoor and in damp areas following
these instructions:
- To prevent moisture admission in the plug the device
should be installed electrically after mounting, at
once. Otherwise a moisture admission has to be
blocked e.g. by using a suitable protection cap. (The
ingress protection in the data sheet is valid for the
connected device.)
- Choose an assembly position, which allows the flow-
off of splashed water and condensation. Avoid per-
manent fluid at sealing surfaces!
- When using a cable gland or outlet device, turn the
outgoing cable downwards. If the cable has to be
turned upwards, then point it downward so the mois-
ture can drain.
- Install the device in such a way that it is protected
from direct solar irradiation. Direct solar irradiation
can lead to the permissible operating temperature
being overstepped in the worst case. By this the op-
erability of the device can be affected or damaged. If
the internal pressure increases due to solar irradia-
tion, measurement errors may be caused.
Take note that no inadmissibly high mechanical stresses
occur at the pressure port as a result of the installation,
since this may cause a shifting of the characteristic curve
or to the demage. This is especially important for very
small pressure ranges as well as for devices with a
pressure port made of plastic.
In hydraulic systems, position the device in such a way
that the pressure port points upward (ventilation).
Provide a cooling line when using the device in steam
piping.
If there is any danger of damage by lightning or
overpressure when the device is installed outdoor, we
suggest putting a sufficiently dimensioned overpressure
protection between the supply or switch cabinet and the
device.
3.2 General installation steps
- Carefully remove the pressure measuring device from the
package and dispose of the package properly.
- Go ahead as detailed in the specific instructions below.
3.3 Installation steps for EN 837
- Use a suitable seal, corresponding to the medium and the
pressure input (e. g. a copper gasket).
- Ensure that the sealing surface of the taking part is per-
fectly smooth and clean. (RZ6.3)
- Screw the device into the corresponding thread by hand.
- Tighten it with a wrench (for G1/4": approx. 20 Nm;
for G1/2": approx. 50 Nm).
- The indicated tightening torques must not be
exceeded!
- Observe the permitted pressures and materials for
G1/4“ and G1/2“ according to EN837:

3.4 Installation steps for internal threads M20x1.5,
M16x1.5 and 9/16" UNF
- Screw the high pressure connection into the internal
thread of the pressure transmitter and tighten it properly
with approx. 160 Nm.
DANGER! The high pressure tube seals metal-to-
metal in the chamfer of the pressure port. No fur-
ther seal is allowed with this high pressure con-
nection. A wrong installation can cause enor-
mous danger!
4. Electrical Installation
WARNING! Install the device in currentless condition
only!
Establish the electrical connection of the device according to
the technical data shown on the manufacturing label, the
following table and the respective wiring diagram.
After the installation it is recommended to adjust the offset
of the pressure transmitter (see chapter offset and span).
The calibration is not affected by postadjustment of the
offset.

Generation of the 80 % calibration signal:
For the generation of the 80 % calibration signal you have to
put on the connection contacts 80+ and 80- a voltage about
minimal 5 V in the pressureless condition. The maximum volt-
age has to be the same as the maximum supply voltage of the
device. By feeding the voltage on 80+ and 80- an additional
current about 12.8 mA is given out and there flows a complete
current about 16.8 mA. Please note for IS-devices that the ac-
tivation of the calibration signal has to run about the same sup-
ply as the supply of the signal circuit.
!For devices with cable socket, you have to make sure that
the external diameter of the used cable is within the
allowed clamping range. Moreover you have to ensure
that it lies in the cable gland firmly and cleftlessly!
!Please note for devices with ISO 4400 plug, that the cable
socket has to be mounted properly to ensure the ingress
protection mentioned in the data sheet. Please check if
the delivered seal is placed between plug and cable
socket. After connecting the cable fasten the cable socket
on the device by using the screw.
!On devices with field housings, the terminal clamps are
situated under the metal cap. To install the device
electrically, the cap must be screwed off. Before the cover
is screwed on again, the O-ring and the sealing surface
on the housing have to be checked for damages and if
necessary to be changed! Afterwards screw the metal cap
on by hand and make sure that the field housing is firmly
locked again.
!Prevent the damage or removal of the PTFE filter which
is fixed over the end of the air tube on devices with cable
outlet and integrated air tube.
For the electrical connection a shielded and twisted
multicore cable is recommended.
If a transition is desired from a transmitter cable with
gauge tube to acable without gauge tube, werecommend
our terminal box KL 1 or KL 2.
5. Initial start-up
WARNING! Before start-up, the user has to check for
proper installation and for any visible defects.
WARNING! The device can be started and operated by
authorized personnel only, who have read and under-
stood the operating manual!
WARNING! The device has to be used within the tech-
nical specifications, only! (compare the data in the data
sheet)
6. Placing out of service
WARNING! Disassemble the device only in current and
pressure less condition! Check before disassembly, if it is
necessary to drained off the media before dismantling!
WARNING! Depending on the medium, it may cause dan-
ger for the user. Comply therefore with adequate precau-
tions for purification.
7. Maintenance
In principle, this device is maintenance-free. If desired, the
housing of the device can be cleaned using a damp cloth and
non-aggressive cleaning solutions, in switched-off state.
With certain media, however, the diaphragm may be polluted
or coated with deposit. It is recommended to define corre-
sponding service intervals for control. After placing the device
out of service correctly, the diaphragm can usually be cleaned
carefully with a non-aggressive cleaning solution and a soft
brush or sponge. If the diaphragm is calcified, it is recom-
mended to send the device to BD SENSORS for decalcifica-
tion. Please note the chapter “Service/Repair” below.
!A false cleaning of the device can cause an irreparable
damage on the diaphragm. Therefore never use pointed
objects or pressured air for cleaning the diaphragm.
8. Service / Repair
8.1 Recalibration
During the life-time of a transmitter, the value of offset and
span may shift. As a consequence, a deviating signal value in
reference to the nominal pressure range starting point or end
point may be transmitted. If one of these two phenomena oc-
curs after prolonged use, a recalibration is recommended to
ensure furthermore high accuracy.
8.2 Return
Before every return of your device, whether for recalibration,
decalcification, modifications or repair, it has to be cleaned
carefully and packed shatter-proofed. You have to enclose a
notice of return with detailed defect description when sending
the device. If your device came in contact with harmful
substances, a declaration of decontamination is additionally
required. Appropriate forms can be downloaded from our
homepage www.bdsensors.com. Should you dispatch a
device without a declaration of decontamination and if there
are any doubts in our service department regarding the used
medium, repair will not be started until an acceptable
declaration is sent.
If the device came in contact with hazardous
substances, certain precautions have to be
complied with for purification!
8.3 Offset and span
The offset configuration can be performed after loosing and
opening of the upper closing screw via the upper potentiometer
(both direction electrical connection). Use for the offset confi-
guration a clockmaker screwdriver 0.5.
9. Disposal
