2 Basic safety instructions

2.1 General notes

The product was constructed, manufactured, and tested according to the following standards and safety regulations:

■ EMC directive 2004/108/EC

Furthermore, the following harmonized standards and other standards were applied:

■ EN 61000-6-2 Electromagnetic compatibility (EMC); generic standard for immunity

to interference; industrial sector

■ EN 61000-6-4 Electromagnetic compatibility (EMC); generic standard for emitted

interference; industrial sector For this specification, a screened connection cable must be used. The CE mark is on the valve’s type plate.

2.2 Intended use

The piezo-pneumatic switch valves with two valve type series serve to control compressed air in the commercial/industrial sector (measuring and control technology) with additional requirements for explosion protection for intrinsically safe applications. They fulfill all requirements for installation in intrinsically safe electric circuits.

Typical areas of application are pneumatic process flow controls and process technology (turning and positioning drives) in measuring and control technology with special demands for low energy consumption and the lowest self-heating.

1. To ensure perfect, risk-free function and a long life span of the device, follow the

notes in these operating instructions and adhere to the usage conditions and permissible data according to the data sheet and type plate.

2. The usage planning and operation of the device must be done according to the

recognized rules of technology.

3. Prevent unintentional activations or impermissible interference by taking suitable

measures.

1. Design the control system so that no hazardous situation can arise due to a failure of

the valve. The valve is not a safety component for functional safety according to EN ISO 13849-1.

2. The manufacturer of the entire subsection must prove the safety concept of

intrinsically safe electric circuits according to DIN EN 60079-14; VDE 0165-1.

3. For the interconnection of the valves with the intrinsically safe electric circuits of the

associated tools, heed the respective highest values of the field device and the associated device in the interest of explosion protection.

3.1 Function

The piezo-pneumatic switch valves with two valve type series serve to control compressed air with additional requirements for explosion protection for intrinsically safe applications.

Both valve type series distinguish themselves essentially through their pneumatic connections:

■ S9-G⅛: 3/2-, 5/2-, and 5/3-way valve S9 for pipe connection ⅛"

Piezo valve type: P8 381

■ S9-G¼: 3/2-, 5/2-, and 5/3-way valve S9 for pipe connection ¼"

Piezo valve type: P8 385

■ S29: 3/2-, 4/2-, and 5/2-way valve S29 for pipe connection ¼"

(supply air, ventilation) and NAMUR connection (working connections)

Piezo valve type: P8 381 A valve consists of a spool valve that is upstream of one or two piezo valves. The spool

valve is connected electrically to the piezo valve via a device outlet. With manual operation, the spool valve can be operated without electrical activation. See

Manual operation, page 27.
