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
Assembly and Commissioning
The control switch and the corresponding
position 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.
Assembly/disassembly

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.
The control switch may be connected and
assembled 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

Standards conformed to
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 parallel
conductors 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:

and
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 switches
can 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).
