2. Design and function
2.1 Overview, diaphragm seal system
2.2 Description
The flush diaphragm at the process connection of the diaphragm seal system transmits
the process pressure via a system fill fluid to the pressure sensor. The model DSSA11SA
diaphragm seal system is available in different versions.
■1 or 2 PNP/NPN switch points
■With additional IO-Link interface or teach function for switch points
■3 case designs
– Circular connector M12 x 1 with or without 360° LED status indication
– Circular connector M12 x 1, metal version
– Angular connector DIN 175301-803 A with or without 360° LED status indication
In the basic version, the instrument is fitted with a pressure sensor without a display,
which, depending on the application, can be used either for pressure monitoring or as an
electronic PNP/NPN switch for process control.
With an additional IO-Link interface, the instrument can be programmed flexibly and has
integrated diagnostic functions that monitor the instrument status. In addition, this allows
the digital signal to be configured externally and conveniently at any time.
This version, which has been enhanced with a 360° LED status indication, provides visual
information about the status and enables intuitive and quick error detection and correc-
tion. For maintenance, a blinking function via IO-Link facilitates the clear localisation of a
diaphragm seal system.The blinking function prevents confusion of measuring locations
and accelerates maintenance.
In addition to the IO-Link, the teach function enables a further on-site configuration of the
switch point if a convenient factory setting of the point is not possible.

A customer-specific switch point setting can be defined when ordering. If no additional
ordering information is provided, the factory setting is set for switching at the full scale
value and for switching back at 90 % of the full scale value.The switch point setting can
only be subsequently parameterised for diaphragm seal systems with an IO-Link interface
or teach function.

2.4 Product passport
The product passport is a web application where various information about an instrument
can be retrieved by entering the 11-digit alphanumeric serial number. This includes, for
example, instrument configuration, article number, operating instructions, data sheet or
calibration certificates.The product passport can be retrieved from the product page or
directly from the corresponding web application (https://portal.wika.com/serial/).

3. Safety
3.1 Intended use
The model DSSA11SA diaphragm seal system is used on the one hand for the
pressure-dependent switching of circuits by means of a PNP or NPN output signal for
process control. Moreover, versions with standardised IO-Link interfaces can easily
be configured and the instrument status can be monitored. Depending on the selected
measuring range, the instrument can be used for measuring gauge pressure/vacuum or
absolute pressure.
The compact instrument has been designed for industrial hygienic applications (for
indoor and outdoor areas).The all-welded diaphragm ensures a long service life and leak
tightness.The requirements of CIP (cleaning in place) and SIP (sterilisation in place) are
fulfilled. Process connection and system fill fluid are suitable for the food and pharma-
ceutical industry and, depending on the version, are available for applications with 3-A or
EHEDG requirements.

WARNING!
Physical injuries and damage to property and the environment through
exceeding the performance 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 perfor-
mance limits. Only operate the instrument with media that cannot damage
the wetted parts.
→ For performance limits, see product label of the instrument and chapter 9
“Specifications”
▶Any permanent operation in the overload range is not permissible. Above
the end of measuring range, up to the overpressure limit, the instrument
is operating outside its specification.This pressure range is intended to
prevent damage to the instrument, as part of a pressure vessel system,
during the pressure containment test.
▶The overpressure limit must never be exceeded, even when failures occur
in the end-use application. Loads above the overpressure limit can cause
irreversible damage, which can lead, for example, to safety or permanent
measured errors.When the overpressure limit is exceeded, the instrument
must be replaced.
▶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.
▶Do not use the instrument with highly viscous, abrasive and aggressive
media.
▶The electrical hazards specified in chapter 5 “Commissioning, operation”
have to be taken into account.
▶The instrument is not permitted to be used in hazardous areas!
▶After an external fire (generation of heat, direct flame impingement, smoke
or heat radiation), the instrument must be replaced or sent to WIKA for
inspection.
The (dis)mounting, installation, parameterisation and maintenance of the DSSA11SA in
industrial environments absolutely requires suitably skilled personnel in accordance with
chapter 3.4 “Personnel qualification”.
Pressure surges below the nominal pressure and shorter than 1 ms can cause
measured errors.
The instrument has been designed and built solely for the intended use described here,
and may only be used accordingly. No separation into its components is permissible.
The technical specifications contained in these operating instructions must be observed.

EN
14543105.01 08/2023 EN/DE
After exceeding the specification limits or in case of visible changes to the instrument, this
must be stopped immediately and checked by an authorised WIKA service engineer.The
manufacturer shall not be liable for claims of any type based on operation contrary to the
intended use.
Should the operating instructions not be observed or complied with, approvals (e.g.
EHEDG) can become invalid.
3.2 Improper use
WARNING!
Injuries through improper use
Improper use of the instrument can lead to hazardous situations and injuries.
▶Refrain from unauthorised modifications/repairs to the instrument.
▶Do not use the instrument as part of a safety device for protection against
exceeding permissible limits (safety accessory).
▶The instrument must not be used as a climbing aid.
Any use beyond or different to the intended use (see chapter 3.1) is considered as
improper use.
3.3 Responsibility of the operator
The instrument is used in the industrial sector.The operator is therefore responsible for
legal obligations regarding safety at work.
The safety instructions within these operating instructions, as well as the safety, accident
prevention and environmental protection regulations for the application area must be
maintained.
The operator is obliged to maintain the product label in a legible condition.
To ensure safe working on the instrument, the operating company must ensure
■that the instrument is suitable for the particular application in accordance with its
intended use.
■that the instrument is only used in applications that lie within its technical performance
limits (e.g. max. ambient temperature, material compatibility, ...).
■that the compatibility between the wetted parts, the medium and the environment is
ensured.
■that the requisite personal protective equipment is provided.
