4.1 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
In general the level switch can be mounted in any position. The instru-
ment must be mounted in such a way that the probe is at the height of
the requested switching point.
Before beginning the welding work, remove the electronics module
from the sensor. By doing this, you avoid damage to the electronics
through inductive coupling.
Ground the probe before welding directly on the rod or cable.
Devices with threaded fitting are screwed into the process fitting with
a suitable wrench via the hexagon.
See chapter "
Dimensions
" for wrench size.
Warning:
The housing or the electrical connection may not be used for screw-
ing in! Depending on the device version, tightening can cause dam-
age, e. g. to the rotation mechanism of the housing.
With threaded versions, the housing must not be used to screw in the
instrument! Applying tightening forces on the housing can damage its
internal parts.
Use the hexagon for screwing in.
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
