General instructions

Note:
For safety reasons, the instrument must only be operated within the
permissible process conditions. You can find detailed information 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 ex-
posed to the process are suitable for the existing process conditions.
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
The instrument is suitable for standard and extended ambient condi-
tions acc. to DIN/EN/IEC/ANSI/ISA/UL/CSA 61010-1. It can be used
indoors as well as outdoors.
In general, OPTISWITCH 3300 C can be installed in any position. The
instrument only has to be mounted in such a way that the vibrating
element is at the height of the desired switching point.
Use the recommended cables (see chapter " Connecting to power
supply") and tighten the cable gland.
You can give your instrument additional protection against moisture
penetration by leading the connection cable downward in front of the
cable gland. Rain and condensation water can thus drain off. This
applies mainly to outdoor mounting as well as installation in areas
where high humidity is expected (e.g. through cleaning processes) or
on cooled or heated vessels.
To maintain the housing protection, make sure that the housing lid is
closed during operation and locked, if necessary.
