the device, the following instructions have to be worked
out by qualified technical personnel.
1.4 Limitation of liability
By non-observance of the operating manual, inappropriate
use, modification or damage, no liability is assumed and
warranty claims will be excluded.
1.5 Intended use
- The electronic pressure switch DS 6 has been designed
for universal use. Preferred areas of use are, among
others, machine building industry, hydraulics, meas-
urement, and controls. Media wetted materials are
stainless steel for the pressure port, ceramics Al2O3for
the pressure sensor, and FKM or EPDM for the seals.
These materials have been chosen particularly in order
to achieve high media compatibility even in standard
version. The new microcontroller switching electronics
offer – besides the standard functions – many additional
features for an optimal adaptation to the measuring re-
quirements. The one or two freely programmable con-
tacts whose status is indicated by differently coloured
LEDs can be quickly and comfortably configured either
by means of the optionally available configuration kits
CIS 685 or CIS 686 or the programming device P6.
- It is the operator's responsibility to check and verify the
suitability of the device for the intended application. If
any doubts remain, please contact our sales department
in order to ensure proper usage. BD|SENSORS is not
liable for any incorrect selections and their effects!
- It has to be ensured, that this medium is compatible with
the media wetted parts.
- The technical data listed in the current data sheet are
engaging. If the data sheet is not available, please order
or download it from our homepage.

WARNING! – Danger through improper usage!
1.6 Package contents
Please verify that all listed parts are undamaged included in
the delivery and check for consistency specified in your
order:
- pressure switch DS 6
- mounting instructions
2. Product identification
The device can be identified by its manufacturing label. It
provides the most important data. By the ordering code the
product can be clearly identified.
! The manufacturing label must not be removed from the
device!
3. Mechanical installation
3.1 General 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 under-
stood the operating 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 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!
- 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 so-
lar irradiation, measurement errors may be caused.
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.
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.
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 Mounting and safety instructions oxygen
DANGER! Explosion hazard, with devices for oxygen
applications, when used improperly. To ensure a usage
without danger, the following points must be adhered to:
- Make sure, your device has been ordered and de-
livered as a special version for oxygen applica-
tions. You can check the manufacturing label (see
figure 1). If the ordering code ends with "007", then
the device is suitable for oxygen applications.
- At time of delivery the device is packed into a plas-
tic bag in order to prevent it from impurity. Please
observe the indication label "Device for oxygen,
unpack only directly before assembling". Also,
avoid any skin contacts during unpacking and as-
sembly, in order to prevent greasy residues on the
device.
- During installation, the respective explosion protec-
tion regulations have to be met. Check, if ATEX-
approval is necessary for this type (oxygen) de-
vice. (the delivered device has no ATEX-approval)
- Note the entire design requirements meet the
standard demand of BAM (DIN 19247).
- Transmitters with o-rings of FKM Vi 567:
permissible maximum values: 25 bar / 150° C
(BAM approval)
3.3 Installation steps
- Carefully remove the pressure measuring device from
the package and dispose of the package properly.
- Check to ensure that the O-ring fits properly into the
groove (seal is supplied with device).
- Ensure that the surface on which the seal should be
placed is perfectly smooth and clean.
- Screw the pressure switch by hand into the thread and
tighten it with a wrench (torque approx. 5 Nm).
- The indicated tightening torques must not be
exceeded!

7. Maintenance
In principle, this device is maintenance-free. If desired, the
housing of the device can be cleaned when switched of
using a damp cloth and non-aggressive cleaning solutions.
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
recommended to send the device to BD|SENSORS for
decalcification. Please read therefore the chapter “Service/
repair” below.
!An incorrect cleaning can cause irreparable damages
on diaphragm. Never use spiky objects or pressured air
for cleaning the diaphragm.

10.1 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 phenome-
na occurs after prolonged use, a recalibration is recom-
mended to ensure furthermore high accuracy.
10.2 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
