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!

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.

Every DS 4 can be quickly and comfortably configured either
by means of the optionally available configuration kits
CIS 680 or CIS 681 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 4 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 680 and CIS 681 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 680) or
USB-interface (CIS 681).
Installing the configuration software P-Set is very easy. P-Set
runs on all Windows
®
PC’s (95, 98, ME, 2000, NT, XP).
Configuration via hand-held programming device P6
The programming device P6 is simply plugged between DS 4
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 (for both set points)
- switch-on and switch-off point (for both set points)
- set point negation (for both set points)
- switch on and switch off delay (for both set points)
- teach switch-on and switch-off point
