Safety instructions
CAUTION
Risk of burns due to hot measuring media
The device surface temperature may exceed 70 °C (158 °F),
depending on the measuring medium temperature!
• Before starting work on the device, make sure that it has
cooled sufficiently.
Aggressive or corrosive media may lead to the damage of
wetted parts of the sensor. As a result, measuring medium under
pressure can leak out.
Wear to the flange gasket or process connection gaskets
(e.g. pipe fitting, Tri-clamp, etc.) may caused a pressurized
measuring medium to escape.
When using internal flat gaskets, they can become brittle
through CIP- / SIP processes.
If pressure surges above the permissible nominal pressure of the
device occur permanently during operation, this may affect the
service life of the device.
If there is a chance that safe operation is no longer possible,
take the device out of operation and secure it against
unintended startup.
Use in Potentially Explosive Atmospheres
Note
• An additional document with Ex safety instructions is
available for measuring systems that are used in potentially
explosive atmospheres.
• Ex safety instructions are an integral part of this manual. As
a result, it is crucial that the installation guidelines and
connection values it lists are also observed.

Figure 67: Position of the DIP switches
DIP switches are located behind the front housing cover. The DIP
switches are used to configure specific hardware functions. The
power supply to the transmitter must be briefly interrupted in
order for the modified setting to take effect.
Write-protect switch
When write protection is activated, device parameterization
cannot be changed via the LCD indicator. Activating and sealing
the write protection switch protects the device against
tampering
Number Function
On Write protection active
Off Write protection deactivated.
Configuration of digital outputs 41 / 42 and 51 / 52
The configuration (NAMUR, optoelectronic coupler) for the
digital outputs on the basic device is set via DIP switches in the
transmitter.
Number Function
On Digital output 41 / 42 and 51 / 52 as
NAMUR output.
Off Digital output 41 / 42 and 51 / 52 as
optoelectronic coupler output.
