Safety instructions
Write-protection switch, service LED and
local operating interface
Write protection switch
If write protection is active, the parameterization of the
device cannot be changed via the local operating interface or
the local display.
Turning the write protection switch clockwise deactivates the
write protection while turning the switch counter-clockwise
activates it.
Service LED
The service LED, which indicates the operating condition of
the device, is located in the sensor terminal box.
Local operating interface
The sensor can also be parameterized without a local display
via the local operating interface, see chapter
"Parameterization via the local operating interface" on
page 29.
Aggressive or abrasive measuring medium may result in
damage to the wetted parts of the flowmeter sensor. As a
result, pressurized measuring medium may escape
prematurely.
Due to wear on the flange seal or process connection gaskets
(e.g., threaded pipe connections, Tri-Clamp, etc.), a
pressurized measuring medium may escape.
When using internal flat gaskets, these can become
embrittled through CIP/SIP processes.
If there is a chance that safe operation is no longer possible,
take the device out of operation and secure it against
unintended startup.
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.
