Control switch

Explosion protection Technical data

Description

This control switch has been designed to solve a great variety of problems encountered in chemical and petrochemical plants and in explosion-proofed electrical machinery. Four switch contacts as opening and closing elements in different permutations permit a large number of functions. The NC contacts have positive break operation. The switch actuator allows both latching and momentary contact with different switch positions.

The control switch can be installed quickly and directly onto a mounting rail, either in double or triple ComEx enclosures or in combination with other command devices in control units.

Safety Instructions

The control switch and the correspondingposition selector switch may be used only within the specified ambient and operating temperature range.

Utilisation in areas other than those specified or the alteration of the product by anyone other than the manufacturer will exempt BARTEC from liability for defects or any further liability.

Incorrect installation can cause malfunctioning and the loss of explosion protection.

The control switch may be connected andassembled only by qualified personnel who are authorised and trained to assemble electrical components in hazardous (potentially explosive) areas.

Always disconnect the control switch from voltage before assembly/disassembly.

The generally applicable statutory rules and other binding directives relating to workplace safety, accident prevention and environmental protection must be adhered to.

The control switch may be used only if it is in a clean and undamaged condition. Dust deposits exceeding 5 mm must be removed.

Marking

Particularly important points in these instructions are marked with a symbol:

DANGER

Non-observance leads to death or serious physical injury. The necessary safety measures must be taken.

CAUTION

Warning of damage to property and financial and penal disadvantages (e.g. loss of guarantee rights, liability etc.).

ATTENTION

Important instructions and information on preventing disadvantageous behaviour.

NOTE

Important instructions and information on effective, economical and environmentally compatible handling.

Standards conformed to

EN 60079-0:2006 EN 60079-1:2004 EN 60079-7:2007

Assembly and Commissioning

Assembly/disassembly

CAUTION

Only authorised and qualified personnel may do any of the assembly, disassembly, installation and commissioning work.

Install the control switch in such a way that it is mechanically protected against impact energy.

Make sure the control switch to be fitted is intact (no cracks).

The connection lead must meet the thermal and mechanical requirements of the area of application.

Installation

In hazardous areas groups I and II the control switch must be used in appropriate enclosures with “Ex e” increased safety type of protection or in an enclosure that corresponds to another approved type of protection specified in EN 60079-0 Section 1. When fitting into an enclosure with “Ex e” type of protection the clearance and creepage distances under EN 60079-7 Section 4.3, Section 4.4 and Table 1 must be observed.

Only suitable tools may be used for installation. It is not permissible to modify the switch in any way.

ATTENTION

Avoid any capacitive influence from parallelconductors as well as any additional adverse heat effects on the conductor.

The ends on fine-stranded and multi-stranded conductors must be prepared. Wire end sleeves must be crimped with suitable crimping tools.

Supply cable, cross-sections: 0.75 - 2.5 mm2 (one-wire) 0.75 - 1.5 mm2 (fine-stranded, wire end ferrule)

The terminals must be tightened with a maximum torque of 2.5 Nm.

Commissioning

Before commissioning check that:

• the device has been installed correctly

• the device is not damaged

• the connection has been established properly

Operation, Maintenance and Fault Clearance

CAUTION

The control switch may be used only if it is in a clean and undamaged condition.

ATTENTION

Only authorised and qualified personnel may do any of the maintenance and fault clearance work

The operator of the control switch must keep it in good condition, operate it properly, monitor it and clean it regularly. The control switch, position selector switch and cables must be checked regularly for cracks and damage.

NOTE

Dirty control switches/position selector switchescan be cleaned with compressed air.

The control switch is defective if the switching unit does not perform switching functions any longer. Defective control switches cannot be repaired; they must be replaced.

Defective position selector switches can be taken out and replaced by functioning position selectors of the same type.

Accessories, Spare Parts

See BARTEC catalogue also.

Disposal

The components in the control switch contain metal and plastic parts.

Therefore the statutory requirements for electrical scrap must be observed (e.g. disposal by an approved disposal company).
