the pressure sensor, and FKM or NBR 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.

stood the operating manual!
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).
- For devices with oxygen capability up to 50 bar, o-
rings V747-75 with BAM-approval are being used.
The max. capabilities allowed, are 40 bar/130°C
and 50 bar/100°C.
- For devices with oxygen capability over 50 bar, o-
rings FKM 90 are being used. These have been
tested 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
prevent damage of the device and the plant!
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 assembly stress occurs at the
pressure port, since this may cause a shifting of the
characteristic curve.
3.2 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 set points are factory set either to ordered values or to
BD SENSORS standard:
Switching function n/o (normally opened)
Switching mode hysteresis mode
Switch on point 80 % FSO
Switch off point 75 % FSO
Switch on/switch off delay off
Set point adjustment – user specific
Every DS 6 can be quickly and comfortably configured either
by means of the optionally available configuration kits
CIS 685 or CIS 686 as well as the programming device P6.
These devices can be ordered as accessories from
BD SENSORS. In the following, a short description of these
possibilities is given:
Configuration via configuration kit
The DS 6 can be connected to a PC via the programming
adapter and configured by the programming-software P-Set.
The setting of the following parameters for both set points is
possible:
- operation mode (hysteresis or window mode)
- switch-on and switch-off point
- set point negation
- switch on and switch off delay
The programming adapter is part of the programming kits
CIS 685 and CIS 686 which contains i.a. a CD-ROM with the
configuration software P-Set. All cables required for connect-
ing the pressure switch have to be plugged to the program-
ming adapter (included in scope of delivery). The user only
requires a Windows
®
PC with serial interface (CIS 685) or
USB-interface (CIS 686). Installing the configuration soft-
ware P-Set is very easy. P-Set runs on all Windows
®
PC’s
(95, 98, ME, 2000, NT, XP).
Configuration via programming device P6
The programming device P6 is simply plugged between
DS 6 and the female connector. Via two push-buttons and a
4-digit LED display, all possible settings can be realized. The
menu system of the device includes 27 menus and is easy
to handle. The following menus are – among others –
available for configuration:
- read all and store all
- operation mode
- switch-on and switch-off point
- set point negation
- switch on and switch off delay
- teach switch-on and switch-off point
- load of stored configurations
- storage off current configurations
- showing the current pressure value
- showing the limits of the measuring range
7. Placing out of service
WARNING! When dismantling the device, it must
always be done in the depressurized and currentless
condition! Check also if the medium has to be drained
off before dismantling!
WARNING! Depending on the medium, it may cause
danger for the user. Comply therefore with adequate
precautions for purification.
8. 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.
Depending on the measuring medium, however, the dia-
phragm may be polluted or coated with deposit. If the
medium is known for such tendencies, the user has to set
appropriate cleaning intervals. 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 read therefore the chapter “Repair” below.
! An incorrect cleaning can cause irreparable damages
on diaphragm. Never use spiky objects or pressured air
for cleaning the diaphragm.
9. Return
9.1 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 phenom-
ena occurs after prolonged use, a recalibration is recom-
mended to ensure furthermore high accuracy.
9.2 Return
Upon every return of the device, no matter if for recalibration,
decalcification, modifications or repair, it is necessary
to contact us to guarantee a quick execution of your
request. Please inform us by sending an email to:
