CAUTION!
... indicates a potentially dangerous situation that can result in light injuries or damage to property or the
environment, if not avoided.
WARNING!
... indicates a potentially dangerous situation that can result in burns, caused by hot surfaces or liquids,
if not avoided.
Information
... points out useful tips, recommendations and information for ecient and trouble-free operation.
3.2 Intended use
The instrument has been designed and built solely for the intended use described here, and may only be used
accordingly.
The manufacturer shall not be liable for claims of any type based on operation contrary to the intended use.
Intended use
The model PSD-4-ECO pressure switch is used for the switching of circuits as a function of the measured pressure
via a PNP or NPN output signal. In addition, the pressure value can be output to appropriate read-out units as a
standardised analogue signal (4 ... 20 mA or DC 0 ... 10 V) or digital signal (IO-Link 1.1). The switching conditions can
be programmed directly at the pressure switch or by means of IO-Link 1.1 (switch and reset points, normally closed/
normally open, ...). Via the dierent display elements of the pressure switch, switching states and pressure values can
be read on site.

mance limits
Exceeding the performance limits can destroy the instrument and lead to danger in the end-use
application.
▶
Only use the instrument in applications that lie within its technical performance limits. → For
performance limits, such as derating (maximum current consumption at a corresponding medium
temperature), see chapter 9 “Specifications”
▶
Any permanent operation in the overload range is not permitted. Above the highest operating
pressure permitted, up to the overload limit, the pressure sensor is operating outside its specification. The overload range is intended to prevent damage to the pressure sensor, as part of a pressure
vessel system, during the pressure containment test.
▶
The overload limit must never be exceeded, even when failures occur in the end-use application.
Loads above the overload limit can cause irreversible damage, which can lead, for example, to
permanent measuring errors.
▶
The manufacturer or operator of the machine or plant in which the product is used must ensure the
compatibility of the materials of the wetted parts with the medium used.
▶
The pressure switch should not be used with abrasive or unstable fluids, in particular not with
hydrogen.

3. Safety
■
Pressure surges below the nominal pressure and shorter than 1 ms can cause measuring errors.
■
For applications where pressure spikes can occur, the use of a restrictor is recommended. The
restrictor narrows the pressure port to 0.6 mm and thus increases the resistance against pressure
spikes.
■
With media that could block the pressure port (e.g. through particles), it is recommended to use a
wider pressure port of 6 or 12 mm.
■
There must be no build-up of atomic hydrogen in the pressure port of the pressure switch.
3.3 Personnelqualication
Skilled personnel
Skilled personnel, authorised by the operator, are understood to be personnel who, based on their technical training,
knowledge of measurement and control technology and on their experience and knowledge of country-specic regulations, current standards and directives, are capable of carrying out the work described and independently recognising
potential hazards.
3.4 Use of accessories and spare parts
It is recommended to use original accessories and original spare parts from WIKA. Using accessories and spare parts
from third parties can lead to damage to the instrument or accidents, due to quality defects or other reasons.
WIKA assumes no liability for damage or accidents caused by a malfunction or unsuitability of accessories and spare
parts which do not originate from WIKA (e.g. non-compliance with the IP ingress protection of connectors). No warranty
claims can be made which arise due to a malfunction or unsuitability of any accessory or spare part from a third party.

4. Transport, packaging and storage
4.1 Transport
Check the pressure switch for any damage that may have been caused by transport.
Obvious damage must be reported immediately.
4.2 Packaging and storage
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g. change in installation site, sending for
repair).
Permissible conditions at the place of storage:
■
Storage temperature: -40 ... +70 °C
■
Humidity: 45 ... 75 % relative humidity (no condensation)
5. Commissioning, operation

Delay times (0 ... 65 s)
This makes it possible to lter out unwanted pressure peaks of a short duration or
a high frequency.
The pressure must be present for at least a certain pre-set time for the output to
switch on. The output does not immediately change its status when it reaches the
switching event (SP), but rather only after the pre-set delay time (DS).
If the switching event is no longer present after the delay time, the switch output
does not change.
The output only switches back when the system pressure has fallen down to the
reset point (PR) and stays at or below the reset point (RP) for at least the pre-set
delay time (DR).
If the switching event is no longer present after the delay time, the switch output
does not change.

ERR Internal error (restarting the instrument or resetting to factory settings can provide a solution)
The analogue output controls the alarm signal ≤ 3.6 mA (4 ... 20 mA output signal) or ≥ 11 V
(0 ... 10 V output signal) in accordance with NAMUR43
EN
ERR1 Instrument temperature exceeded/too low or power supply too low
ERR2 Sensor defect detected, check whether high overload pressure is present (can be detected as sensor defect), if
SC Short-circuit detected at switching output 1 or 2
Acknowledge warnings and errors with conrmation button.
The switching outputs keep the current switching state (output open or closed)
The analogue output is output. There are limitations with respect to accuracy (temperature inuence) and
maximum analogue value (power supply too low)
The switching outputs keep the current switching state (output open or closed)
necessary, restart instrument or exchange of instrument is needed
The analogue output controls the alarm signal ≤ 3.6 mA (4 ... 20 mA output signal) or ≥ 11 V
(0 ... 10 V output signal) in accordance with NAMUR43
The switching outputs keep the current switching state (output open or closed)
The switching output aected is inactive so long as the short-circuit is present
The user must ensure a regular change in pressure and thus a proportional output signal change. The
pressure transmitter does not have any diagnostic function for detecting a static signal as a result of an
instrument error.
