General instructions
The instrument is suitable for standard and extended ambient
conditions acc. to DIN/EN/IEC/ANSI/ISA/UL/CSA 61010-1. It can be
used indoors as well as outdoors.
Note:
For safety reasons, the instrument must only be operated within
the permissible process conditions. You can find detailed informa-
tion on the process conditions in chapter " Technical data" of the
operating instructions or on the type label.
Hence make sure before mounting that all parts of the instrument
exposed to the process are suitable for the existing process condi-
tions.
These are mainly:
•
Active measuring component
•
Process fitting
•
Process seal
Process conditions in particular are:
•
Process pressure
•
Process temperature
•
Chemical properties of the medium
•
Abrasion and mechanical influences
Protect your instrument against moisture ingress through the follow-
ing measures:
•
Use a suitable connection cable (see chapter " Connecting to
power supply")
•
Tighten the cable gland or plug connector
•
Lead the connection cable downward in front of the cable entry
or plug connector
This applies mainly to outdoor installations, in areas where high hu-
midity is expected (e.g. through cleaning processes) and on cooled
or heated vessels.
Note:
Make sure that during installation or maintenance no moisture or
dirt can get inside the instrument.
To maintain the housing protection, make sure that the housing lid is
closed during operation and locked, if necessary.
Mounting instructions
Radar sensors for level measurement emit electromagnetic waves.
The polarization is the direction of the electrical component of these
waves.
The polarization direction is marked on the housing, see following
