In conformity with DIN EN 60079-14/2004,para.5.2.3,point
c1,VEGASON 63 is suitable for use in zone 2.
The operator must use the instrument as it was intended to be
used and follow the specifications of the following documents:
lthis operating instructions manual
lthis manufacturer declaration (24630)
lthe applicable installation regulations
Max.increase of the surface temperature during operation:
23 K(individual components in the instrument)
With an ambient temperature of 70 °C(158 °F)on the housing
and a process temperature of 70 °C(158 °F), the max.ambient
temperature during operation is 93 °C(199 °F).
Measures to maintain explosion protection during operation:
lOperate the instrument in the range of the specified
electrical limit values.Permissible supply voltage:see
"Technical data"
lMount and operate the instrument in such a way that no
danger of ignition by electrostatic charges is to be
expected.Transducer,process fitting and housing (as the
case may be depending on instrument version)are made
of electrically non-conductive plastic.
lMake sure that the seal is mounted correctly between
lower part of the housing and cover.Screw the cover on
tightly.
lMake sure there is no explosive atmosphere present if you
intend to operate the instrument with opened cover
lMake sure that the cable gland is tight and strain-relieved.
The outer diameter of the connection cable must be
adapted to the cable gland.Tighten the pressure screw of
the cable gland carefully.
lCover unused openings for cable glands tightly
lMount the instrument in such a way that the sensor cannot
touch the vessel wall or vessel installations.Keep in mind
the influence of product movement in the vessel.
lThe surface temperature of the housing must not exceed
the ignition temperature of the surrounding explosive
atmosphere
This instrument was assessed by a person who fulfils the DIN
EN 60079-14 requirements.
