Warning!
• 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.
• 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.
• 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:
– 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).
!
Note!
The device is configured for the Pressure measuring mode as standard. The measuring range and
the unit in which the measured value is transmitted correspond to the specifications on the
nameplate.
