3 Switches in conformity with ATX directive / Technical concepts ATX Directive The ATX mark (Atmospheres xplosives) refers to two uropean directives concerning the risk of deflagration in potentially explosive atmospheres: - ATX 94/9/C: concerns the requirements for electrical and non-electrical equipment used in potentially explosive environments. According to this directive the manufacturer has to comply with the provided requirements and mark the articles in conformity with particular categories. - ATX 99/92/C: regards the minimum safety and sanitary requirements that the user has to satisfy during the activity in potentially explosive environments. These directives determine the requirements for the safety and health protection of people, animals and property and carry several procedures for the conformity demonstration of equipment to the directive requirements. Classification of the potentially explosive atmospheres A potentially explosive atmosphere is an atmosphere that could become explosive according to the local conditions of work. Usually it consists in environments where it is present a mixture of air and flammable substances in the form of gas, smog, steams and dusts. The ATX 99/92/C directive defines for two types of explosive atmosphere, depending on the presence in the zone of gases or combustible dusts. ach area exposed to these types of explosive atmospheres is classified in three zones, according to the frequency and duration of the explosive atmosphere. For atmospheres with explosive gas, areas are classified in zones 0, and 2; for atmosphere with explosive dusts in zones, 2 and : - Zone 0/: a place where gas or combustible dust is present permanently. Constant danger. quipment of minimum category is required. - Zone /2: a place where gas or combustible dust is likely to occur during normal operation. Potential danger. quipment of minimum category 2 is required. - Zone 2/: a place where gas or combustible dust is unlikely to occur or only for a short period. Lower danger. quipment of minimum category 3 is required. It s under the responsibility of the final user to choose and classify the different zones and to use suitable equipments. quipment categories ATX 94/9/C directive distinguishes equipment between two main groups: - Group I: equipment and systems for mining - Group II: equipment and systems for all other applications quipment of the group I is divided in two further categories according to the required protection degree: - Category M: equipment designed to assure a very high protection degree - Category : equipment designed to assure a high protection degree quipment of the group II is divided in three further categories according to the required protection degree: - Category : equipment designed to assure a very high protection degree (use in zones 0 and, and 2, 2 and ) - Category 2: equipment designed to assure a high protection degree (use in zones and 2, 2 and ) - Category 3: equipment designed to assure a normal protection degree (use in zones 2 and ) The relation between the PL (quipment Protection Levels) of the IC 09-0 standard, and the categories and applications of the ATX directive are shown in the table below. Table Classification of the environment and appliance according to the ATX directive and the IC 09-0 standard nvironment characteristics quipment characteristics nvironment of application Flammable material Potentially explosive atmosphere Classifications of the potentially explosive atmospheres: ZON according to ATX 94/9/C Required marking of the applied device: CATGORY Required marking of the applied device: GROUP according to IC 09-0 PL Required degree protection Mining M Ma I Mb high very high It is present continuously, for long periods or frequently 0 G Ga very high Gases It is likely to occur 2G Gb high Surface It is unlikely to occur or, if it does, is likely to do infrequently and for a short period only 2 3G Gc normal II It is present continuously, for long periods or frequently D Da very high Dusts It is likely to occur 2 2D Db high It is unlikely to occur or, if it does, is likely to do infrequently and for a short period only 3D Dc normal 2/39 General Catalog -2

4 Methods of protection In order to avoid an explosion caused by the electrical ignition of an explosive atmosphere, it is possible to take different type of precautions: - Isolate the dangerous parts into housing in order to limit the explosion inside itself. - Avoid contact between ignition sources and the potentially explosive atmosphere interposing solid, liquid or gaseous materials. - Take measures in order to limit the generation of dangerous ignition sources, eliminating the possibility of faults or limiting the energy so it s not sufficient to cause the ignition. For each modality several methods of protection have been developed and standardized, as listed in the following table.

Adjustable levers In switches with revolving lever it is possible to adjust the lever with 0 steps for all the 3 range. The positive movement transmission is always guaranteed thanks to the particular geometrical coupling between the lever and the revolving shaft in compliance with German standard BG-GS-T-. 0 Overturning levers It s possible to fasten the lever on switches in straight or reverse side, maintaining the positive coupling. In this way it s possible to obtain two different work plans of the lever. Rotating heads In all switches, it is possible to rotate the head in 90 steps. Unidirectional heads In switches with revolving lever, you can select the directional operation by removing the four screws of the head and revolving the internal piston.
