WARNING
!
Exceeding the maximum allowable working pressure!
Risk of injury due to bursting of parts! Warning messages are generated if pressure is too high.
‣
If a pressure greater than the maximum permitted pressure is present at the device, the
messages "E115 Sensor overpressure" and "E727 Sensor pressure error - overrange" are
output in succession! Use the device only within the sensor range limits
NOTICE
Shortfall of the allowable working pressure!
Output of messages if pressure is too low.
‣
If a pressure smaller than the minimum permitted pressure is present at the device, the
messages "E120 Sensor low pressure" and "E727 Sensor pressure error - overrange" are
output in succession! Use the device only within the sensor range limits
7.1 Configuring messages
• Messages E727, E115 and E120 are "Error"-type messages and can be configured as a
"Warning" or an "Alarm". These messages are configured as "Warning" messages at the factory.
This setting prevents the current output from assuming the set alarm current value for
applications (e.g. cascade measurement) where the user is consciously aware of the fact that
the sensor range can be exceeded
• We recommend setting messages E727, E115 and E120 to "Alarm" in the following instances
(

see Operating Instructuions BA00294P):
– The sensor range does not have to be exceeded for the measuring application.
– Position adjustment has to be carried out that has to correct a large measured error as a
result of the orientation of the device (e.g. devices with a diaphragm seal).
