GEA T.VIS M-15, Инструкция по эксплуатации

Страница: 11 / 120

No technical modifications should ever be made to this component. Otherwise
you will have to undergo a new conformity process in accordance with the EC
Machinery Directive on your own.
In general, only original spare parts supplied by GEA Tuchenhagen GmbH
should be fitted. This ensures that the component is always operating properly
and efficiently.
2.4 IP Protection Classes
The control top T.VIS M-15 in its standard version fulfils the requirements of
protection class IP66 (DIN EN 60529). Models in protection classes IP67 or
IP69k (both DIN EN 60529) are also available.
IP classes provide information about the degree of protection an electrical device
housing provides against the ingress of solids (first digit) or humidity (second
digit). They attempt to reproduce common kinds of failure and assign so-called IP
codes to the protected systems. The letters IP stand for 'International Protection'
and are prefixed to the code numbers.
Position of the digit Explanation
1. digit* Protection against solids
6 Dust tight
2. digit* Protection against humidity
6 Protected against powerful water jets
7
Protected against temporary
immersion
9k
Protected against high pressure spray
downs
*For additional digits and more detailed descriptions please refer to the
pertinent standard.
Digits not to be mentioned can be replaced by the letter x (e. g. IPx6).
Concerning the ingress of humidity, IPx6 includes all lower IP classes. This is,
however, not the case for the higher protection class IPx7!
If cleaning agents are used that significantly reduce the surface tension and/or if
high-pressure cleaners are used, we recommend using IP69k rated equipment as
an option.
Hint!
The specified IP classes only apply if the connectors are connected
correctly, if the cable gland is properly sealed and if the control top is
fitted on the valve, see Chapter 6, Page 36.
