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. In applications where the user is consciously aware of the fact that the sensor range
can be exceeded (e.g. cascade measurement), this setting prevents the transference of status
BAD.
•We recommend setting messages E727, E115 and E120 to "Alarm" in the following instances
(→ see Operating Instructions 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).
