4 .1 General instructions
With instruments with threaded process fitting, suitable tools must be
applied for tightening the hexagon.
Warning:
The housing must not be used to screw the instrument in! Applying
tightening force can damage internal parts of the housing.
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 entry. 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.
Make sure that all parts of the instrument exposed to the process, in
particular the active measuring component, process seal and process
fitting, are suitable for the existing process conditions. These include
above all the process pressure, process temperature as well as the
chemical properties of the medium.
You can find the specifications in chapter "Technical data" and on the
type label.
4 .2 Mounting preparations - Horn antenna
The instrument is also available in versions with an antenna whose
diameter is larger than the process fitting (thread, flange). In such
cases the antenna must be disconnected from the process fitting
before mounting. Proceed as follows:
1 Loosen the hexagon socket screws (3) on the antenna socket with
an Allen wrench (size 3)
2 Remove the antenna (4)
Note:
The plastic cone may not be pulled out of the antenna socket.
3 Insert the antenna from below into the vessel socket and secure it
against falling off
4 Retighten the antenna with hexagon screws to the antenna socket;
torque max. 10 Nm (7.5 lbf ft)
