Safety instructions

Limits and rules when using ABB fieldbus accessories
CAUTION
Risk of burns due to hot measuring media
The device surface temperature may exceed 158 °F (70 °C),
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.
• The icon on the name plate indicates the following:

Note
The product has an ABB service account that can be disabled
with this write protection switch.

Write protection DIP switch
Figure 60 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
