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 quali-
fied technical personnel who has read and understood
the operating manual!
DANGER! When used improperly, special versions of
devices suitable for oxygen applications may explode!
To ensure a usage without danger, the following points
must be adhered to:
- Make sure that your device has been ordered as a
special version for oxygen applications and that it
has been delivered conformably. You can check
this easily by reading the manufacturing label (see
figure 1). If your ordering code ends with the num-
bers "007", your device is suitable for the oxygen
application.
- When being dispatched the device is packed into a
plastic bag to keep it from impurity. The indication
label with the text "Device for oxygen, unpack only
directly before assembling" has to be observed!
Furthermore any skin contact must be avoided dur-
ing unpacking and installing the device, so that no
fatty residue remains on the device!
- For installing the respective regulations for explo-
sion protection have to be fulfilled. Please check if
an ATEX-approval is necessary for the application
in addition to the acceptability for oxygen. (the de-
livered device has no ATEX-approval)
- Consider that the entire construction must corre-
spond to the standards of BAM (DIN 19247).
- For transmitters with oxygen acceptability up to
50 bar, O-rings of V747-75 with BAM-approval are
used. The upper limiting values allowed are 40 bar/
130°C and 50 bar/ 100°C.
- For transmitters with oxygen acceptability over 50
bar, O-rings of FKM 90 are used which were tested
for acceptability up to 95° C and 215 bar in the
scientific coal research institute in Ostrava – CZ.
! 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 pre-
vent 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 de-
vice 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
permanent 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
moisture 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
operability of the device can be affected or dam-
aged. If the internal pressure increases due to solar
irradiation, measurement errors may be caused.
! For devices with gauge reference in the housing (small
hole next to the electrical connection), install the device
in such a way, that the gauge reference is protected
from dirt and moisture. Should the device be exposed to
fluid admission, the functionality will be blocked by the
gauge reference. An exact measurement in this condi-
tion is not possible. Furthermore this can lead to dam-
ages on the device.
Take note that no assembly stress occurs at the
pressure port, since this may cause a shifting of the
characteristic curve. 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.

! For devices with cable gland as well as 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!
! For the installation of a device with cable outlet following
bending radiuses have to be complied with:
cable without ventilation tube:
static installation : 5-fold cable diameter
dynamic application: 10-fold cable diameter
cable with ventilation tube:
static installation : 10-fold cable diameter
dynamic application: 20-fold cable diameter
! Please note for devices with ISO 4400 or Buccaneer
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 gsealin
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 a cable without gauge tube, we
recommend 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
technical specifications, only! (compare the data in the
data sheet)
Devices with an accuracy of 0.1 % FSO have micro-
controlled electronics for processing and improving the
signal. Principally, the processing takes more time as for
analogue sensors, which have only an amplifier. Due to
this longer response time, the output signal follows the
measured value discontinuously. For nearly stable
measured values, this characteristic is secondary.
Please compare the specification of the response time
in the data sheet.
Intelligent devices with optional communication
interfaces can also be configured by these electronics.
Offset, span and damping are programmable within the
limits given in the data sheet. For configuring the device,
the programming kit CIS 510 consisting of Adapt 1,
Windows compatible programming software
P-Scale 510, power supply and connecting cable is
necessary. This can be ordered additionally from
DRUCK & TEMPERATUR Leitenberger GmbH, Germany.
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
danger for the user. Comply therefore with adequate
precautions 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.
Depending on the measuring medium, however, the dia-
phragm may be polluted or coated with deposit. Is there a
pollution tendency of the medium, the user has to determine
the appropriate cleaning interval. After placing the device out
of service correctly, the diaphragm can usually be cleaned
carefully with a non-aggressive cleaning solution anda soft
brush or sponge. If the diaphragm is calcified, it is recom-
mended to send the device to LEITENBERGER for decalcifi-
cation. Please note the chapter “Service/Repair” below.
! A false cleaning of the device can cause an eirreparabl
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
occurs after prolonged use, a recalibration is recommended
to ensure furthermore high accuracy.
8.2 Return
Upon every return of the device, no matter if for recalibration
decalcification, modifications or repair, it is yneccessar
to contact us to guarantee a quick execution of your
request.
Clean the device, pack it shatterproof and send it to
DRUCK & TEMPERATUR Leitenberger GmbH, Germany.
