Possible Applications, BTS-Ex Characteristics
1.2 Special conditions for the use in potentially explosive
atmospheres and as safety device in potentially
explosive atmospheres
The devices are only approved for proper and intended use in accordance with the
instructions. Contravention excludes any warranty and responsibility on the part of the
manufacturer!
–
Only use accessories in potentially explosive atmospheres which satisfy all
requirements of European directives and national legislation.
–
In case of explosive dust atmospheres of Explosion Group IIIC, the product may
be used with organic dusts only.
–
It is imperative to comply with the ambient conditions as specified in this operating
manual.
–
The provision of lightning protection measures have to be ensured by the
operator.
–
Ensure that the fusible plugs required in addition are used on each turbo coupling
which is operated with this safety device.
–
If the maximal permissible surface temperature of the turbo coupling is ensured by
this safety device, the type of protection "Protection by ignition source monitoring"
also applies to the turbo coupling.
–
Voith Turbo has to determine the response temperature.
–
The ambient temperatures of individual elements must not exceed the respective
limiting temperatures.
–
Mechanical damage caused by ice formation must be reliably excluded.
–
Locks need to be re-attached after opening and closing.
–
Operation of the safety device is only allowed with undamaged housings and
lines.
–
Make sure to satisfy electromagnetic compatibility when installing the system.
–
On installation, it is vital to observe the nationally applicable provisions governing
installation of equipment, such as EN 60079-14, EN 1127-1 and EN 1127-2.
–
It is mandatory to provide an equipotential bonding. Compliance with provisions
governing the installations into plants in the country of use must to be ensured
(e.g. VDE 0100, part 540, IEC 364-5-54).
–
Avoid electrostatic charging.
–
To ensure the discharge of electrostatic charging, please observe the national
regulations.
•
Non-conductive parts must not exceed a surface of 100 cm² in IIB.
•
It is not allowed to use the BTS-Ex in equipment with electrical corrosion
protection, or after consultation with the manufacturer and by taking special
measures only. It is not permitted to route compensation currents through the
construction.
–
The evaluator is designed for use in Contamination Level 2, as per DIN EN 50178.
Protect the switching element and initiator against the ingress of liquids and/or
impurities, if required. This depends on the operating conditions, e.g. heavy dust
contamination or chemically aggressive fluids.
–
For temperatures below -20 °C, install the initiators with mechanical protection.
