Operating Manual / Piston Pressure Switch

2 Safety

2.1 Correct use

Adhere to the performance limits specified in the technical data.
Correct use also requires that you have read this manual completely, particularly chapter "2.3
Basic safety instructions", and that you have understood everything therein. Please contact our
sales department if in any doubt.
Any use other than or beyond this is considered as incorrect and is, consequently, expressly
prohibited. The owner or operator bears responsibility for all damage resulting from incorrect use.
This pressure switch is not suitable for operation in a potentially-explosive environment.
Correct use also includes:
the heeding of all instructions in the operating manual
the heeding of all mandatory, prohibition and warning signs

2.2 Qualifications of personnel

Commissioning requires fundamental electrical and hydraulic knowledge and knowledge of
associated technical terminology. In order to ensure operational liability, these tasks should
therefore only be entrusted to a suitable skilled worker or an instructed person under the
supervision of a skilled worker who has received regular training and instruction.
A skilled worker is someone who, on the basis of his technical training, know-how and
experience and knowledge of pertinent regulations, can evaluate the work entrusted to him,
identify potential hazards and take suitable safety measures. A skilled worker should adhere to
relevant specific technical rules.

2.3 Basic safety instructions

2.3.1 General information

Changes to the hazard potential may arises as a result of the interaction which occurs following
installation of the pressure switch. Therefore, this operating manual does not replace the
operating instructions for the plant in which the pressure switch is installed. It is imperative that
the superordinate operating manual be read and understood.
The safety instructions are designed to avoid injuries and damage to the plant and environment.
All operators are obliged to read these safety instructions and heed them at all times.
The pressure switch should only be used in a technically flawless condition.
Modifications or conversions of the pressure switch should be avoided, as these render the EC
Declaration of Conformity and operating permit null and void.
The pressure switch should only be used within the performance range specified in the
technical data for the respective pressure switch.
The pressure switch is not suitable for use in a potentially explosive environment.
When exchanging defective components, these should only be replaced with original parts with
the same electrical and mechanical data, as safety and the function can otherwise not be
maintained.
All safety equipment, fixing elements and electrical connections, cables and lines should be
inspected regularly to ensure that they are in a flawless condition.

2.3.2 During installation

The relevant plant section should always be relieved of pressure and de-energized prior to
installing/dismantling the pressure switch.
Secure the plant section against reactivation.
Cables and lines should be laid in a manner that prevents them being damaged (e.g. heat,
cold, ozone, etc.).
Ensure prior to commissioning that all connections are correctly fitted and undamaged to
prevent any liquid emerging.
