## **ATEX Directive 94/9/EC:** os * a : PN general information ; y . .. i y 

## **Principles of Directive 94/9/EC:** : a< 

The directive aims to harmonise the legislation of European Union member states in order to ensure free circulation of equipment intended for use in explosive atmospheres (gas and dust). 

Since 1 July 2003, this directive has applied to electrical, mecha_ nical, hydraulic and pneumatic products. 

It concerns the assessment of protective devices and systems (manufacturers) as well as the design (design office), installation (installers, panel-builders) and maintenance (maintenance depts) of installations. 

## **Definition of an explosive atmosphere:** 

An explosive atmosphere is defined as a mixture of flammable substances (in the form of gas, vapour, mist or dust) with air under atmospheric conditions in which, after ignition, combustion spreads throughout the entire unburned mixture.

## **Some relevant areas:** 

## ANN 

## **Application since 30 June 2003:** = SN 

Manufacturers must offer products, which comply with Directive 94/9/EC and must have a Quality Control System that has been approved by a notified body. 

Users are responsible for using equipment correctly according to the zones they have defined within their installations based on the potential risks. Existing installations must be brought into conformity with the ATEX Directive before 30 June 2006. All new products commissioned must comply with Directive 94/9/EC. In the event of breakdown, installed equipment that cannot be repaired must be replaced with equipment complying with Directive 94/9/EC 

## **Classification:** 

Potentially explosive environments are classified by zone in compliance with Directive 1999/92/EC. This directive is aimed at users. It details the minimum requirements for increasing protection of the health and safety of workers exposed to explosive atmospheres. 

ATEX Directive 94/9/EC defines categories of equipment and protection systems, which can be used in the corresponding zones. 

- **Categories M1 and M2 relate to mines (group I)** 

- **Categories 1, 2 and 3 relate to other locations (group II) often referred to as "Surface industries"** 

## **Documents and recommendations/products:** 

ATEX-certified products must be supplied with an EC declaration of conformity and a user manual. 

At the time of sale, the sales representatives must check the zone in which the product is to be used. On the order, the customer must inform the manufacturer of the conditions of use. 

Manufacturers and distributors must ensure that their sales of ATEX products are traceable (so that customers who have been sold an ATEX product can be located in relation to the product's date of manufacture). 

In the case of an assembly, the product with the lowest certification level determines the level of the whole assembly.

## **Marking example:** 

Certified products must incorporate marking specific to Directive 94/9/EC, such as: 

Crouzet Automatismes SAS 2 rue du Docteur Abel, 26902 Valence, FRANCE Type: 81513530 Serial no: Year of construction **CE 0081** & **II 1 G Ex ia II C T6 LCIE 02 ATEX 6121 X Max. amb. T: +50°C** 

## **Explanation of the marking example:** 

**The CE marking along with the identification number of the notified body responsible for monitoring the QCS (0081 = LCIE). CE 0081** ~~4,~~ **II 1 G** 

- **The** © **symbol indicating that this product can be used in an explosive atmosphere followed by the equipment** 

> 7 **The CE-Type Examination Certificate reference (if appropriate).** 

**LCIE 02 ATEX 6121 X Max. amb. T: +50°C** 

**The ambient operating temperature range.** 

- **group (II = Surface Industries), the category** 

- **(1 = continuous presence; 2 = intermittent presence;** 

- **3 = fleeting presence), and the type of explosive** 

In the event of use in an explosive atmosphere caused by dust, the following items are added to the marking: 

**atmosphere G = Gas, D = Dust.** 

In affixing this CE marking, the manufacturer declares that the product has been manufactured in complete conformity with the requirements of all the relevant directives. 

- **The surface limit temperature T° C for use in an explosive atmosphere caused by dust.** 

**Next line of the marking specified by the harmonised standards:** 

**The IP rating (only for dust)** 

## **Ex ia II C T6 X** 

      - Reference to the operating instructions for the product 

   - Temperature Class corresponding to a max. surface temperature of 85°C 

- Subdivision IIC: including hydrogen acetylene

## **To know** eat , a es “ —; **Manual control valves** 

Manual control valves are deemed to be simple slow-moving components, without any hot surfaces, and are not subject to ATEX Directive 94/9/EC. 

They can be integrated in devices and equipment conforming to the requirements of this directive without adversely affecting conformity. 

Nonetheless, parts of these components made of polymer can have an electrostatic charge and the user must take account of these charges.

## **Pressure switch** 

## **Important** 

**This pressure switch must be connected to an approved safety barrier. Placed in a safe zone, this safety barrier can be used to supply the pressure switch in a hazardous zone.** 

**==> picture [236 x 109] intentionally omitted <==**

1 = common 2 = NC contact closed 

4 = NO contact open 

The electrical connection between the safety barrier (or interface) and the pressure switch can be made using ordinary wires or cables. 

The maximum voltage of the intrinsic safety power supply source should not exceed 60 V. L int ≈ 0 mH C int ≈ 0 µF 

L int = pressure switch inductance C int = pressure switch capacity 

## **Recommended barriers and interfaces** 

These safety interfaces and barriers, recommended by CROUZET, should be obtained from one of the manufacturers indicated below, specifying that they are to be used to supply power to intrinsic safety pressure switch Type 81 513, CE 0081 ll 1 G, approval no. n° LCIE 02 ATEX 6121 X.

**|** PNEUMATICS ATEX 

## **General characteristics** 

## **Operating fluid** 

## **flow graphs** 

- Compressed air or inert gas. 

## **Conditions of use** 

- Operating pressure 2 at 8 bars (except for special conditions). 

- Fluid: Filtered air to 50 microns - non lubricated. 

- Operating temperature from - 5° C to + 50° C (under + 5° C the dew point must be below 10° C for the application). 

- For optimum performance, the elements should be inter-connected by air supply tubing with an internal diameter ≥ at 2.5 mm. 

## **Mounting recommendations** 

- The elements should be mounted and piped in a clean atmosphere in order to prevent any form of pollution entering the system. 

- Minimum torque for element fixing screws: 5 cm/kg. 

- maximum torque for element fixing screws: 10 cm/kg. 

## **Characteristics common to all elements in the modular system** 

- The characteristics have been obtained with a supply pressure at 6 bars. 

- The flow in NI/min is the number of litres of air at normal atmospheric pressure obtained with the output open to atmophere and the supply pressure at 4 bars 

- The consumption in NI/min is the number of litres of free air necessary for the unit to function. 

- kV = the flow coefficient of the equipment. 

- Mechanical life > 10[7] operations. 

## **Sequencer modules** 

Operation results from the combination of a sequential cycle. A system comprises individual modules which are joined together by means of a sub-base. Each module has a memory which delivers an output signal and receives an input signal. 

An indicator on each module allows the operator to monitor the progress of the cycle and identity quickly and easily any fault which may occur.

## **Brake** 

This returns the memory spool to the reset condition only when the supply is lost 

## **Shift register** 

The general principle is to advance the sequencer step by command impulses to the inputs of the even steps, alternating with the command impulses to the inputs of the odd steps. 

Operation results from the combination of three functions (memory, AND and OR) which constitute each module. 

The memory activates the output and gives priority to the reset signal. The AND element ensures the transition to the next module but only if an input signal is present. 

Used for example on a transfer machine to shift the information "bad component" collected at a test-test "n" steps further along the machine to a reject station. 

## **Function diagram** 

The OR element ensures the resetting of all previously operated modules 

## **Function diagram** 

**Auto reset sequencer module** 

## **sequencer module with maintained reset** 

## Brake 

This maintains the memory spool in position only when the supply is lost.

The output signal "s" is present only if the input signal "a" is NOT present. The output signal is therefore the inverse of the pilot signal: S= NOT a S = a 

If the supply port is connected to a 2nd input "b", the function obtained is called inhibition: S = NOT a AND b S = a . b

## **Principle of operation** 

The function is that of a 4/2 valves. The appearence of signal "X1" causes the displacement of the slide valve. The output port "x" is then put under pressure. This state is remembered until the arrival of signal "X0". This signal reverses the slide valve, the output "x" is put under pressure. This state is likewise remembered. The output: 

- "x" under pressure indicates that the information in the MEMORY is "X1", 

- "x" under pressure indicates that the information in the MEMORY is "X0".

## **Note:** 

**Our IP20 miniature solenoid valves (except for those using wire connections) have a location-coding pin, which prevents them from being mounted on our standard subbases. They must only be used with the sub-bases mentioned on page 8 of this catalogue.** 

**If they are being installed with a separate electrical connector, only our 81 516 082 connector should be used in order to comply with safety level EEx ia II C T6.**

## **Miniature solenoid valves** 

## **Important** 

**These ATEX miniature solenoid valves must be connected individually to an approved safety barrier. Placed in a safe zone, these safety barriers can be used to supply ATEX miniature solenoid valves installed in a hazardous zone.**
