1. General information
1.1 Information on the operating manual
This operating manual contains important information on
proper usage of the device. Read this operating manual
carefully before installing and starting up the pressure meas-
uring device.
Adhere to the safety notes and operating instructions which
are given in the operating manual. Additionally applicable
regulations regarding occupational safety, accident preven-
tion as well as national installation standards and engineering
rules must be complied with!
This operating manual is part of the device, must be kept

1.3 Target group
WARNING! To avoid operator hazards and damages of
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 4 has been designed
for pneumatics and vacuum applications. Due to the ma-
terials aluminium for the pressure port and silicon for the
pressure sensor, the DS 4 is suited for use with non-
aggressive gases or compressed air. The housing for the
switching electronics consists of PA 6.6. The new micro-
controller switching electronics offer – besides the stan-
dard functions – many additional features for an optimal
adaptation to the measuring requirements. The one or
two freely programmable contacts whose status is indi-
cated by differently coloured LEDs can be quickly and
comfortably configured either by means of the optionally
available configuration kit CIS 680 or CIS 681 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!

3. 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!
!
Handle
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
directly before starting assembly.
!
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!

Take note that no assembly stress occurs at the
pressure port, since this may cause a shifting of the
characteristic curve.
In hydraulic systems, position the device in such a way
that the pressure port points upward (ventilation).
3.2 General installation steps
- Carefully remove the pressure measuring device from
the package and dispose of the package properly.
- Then go ahead as detailed in the specific instructions
below.
3.3 Installation steps for internal thread G1/8"
- Use a suitable seal for sealing, e. g. Teflon strip, flat
gasket or O-ring, on the screwed end of the counterpart.
- Ensure that the surface of the taking part is perfectly
smooth and clean.
- Tighten the counterpart with a wrench (max. torque
3 Nm).
3.4 Installation steps for internal thread M5
- For sealing use an O-ring that fits properly into the
groove. (O-ring is not included in the scope of delivery)
- Ensure that the surface of the counterpart is perfectly
smooth and clean.
- Screw the counterpart (e.g. screw connection, quick
coupling) by hand into the pressure switch.
- Tighten the counterpart with a wrench (max. torque
1 Nm).
3.5 Installation steps for flange mounting (possible with
internal thread M5)
- For sealing use an O-ring that fits properly into the
groove. (O-ring is not included in the scope of delivery)
- Ensure that the surface of the counterpart is perfectly
smooth and clean.
- There are 4 threads (M3) for flange mounting.
- Install the device with 2 or 4 screws on the intended
flange. When using low pressure ranges and usual con-
ditions for the application are given, 2 screws will suffice.
- Tighten the screws; the surfaces of pressure switch and
counterpart must bear on each other.
4. Electrical Installation
