Warning!
• If a pressure that is lower than the minimum permitted pressure is present at the device,
messages "E120 sensor low pressure" and "E727 sensor pressure error - overrange" are output
in succession.
• If a pressure that is greater than the maximum permitted pressure is present at the device,
messages "E115 sensor overpressure" and "E727 sensor pressure error - overrange" are output
in succession.
• The messages E727, E115 and E120 are "Error"-type messages and can be configured as a
"Warning" or an "Alarm". The factory setting for these messages is "Warning". This setting
prevents the BAD status from being transmitted in applications (e.g. cascade measurement)
where the user is aware of the risk of the sensor range being overshot.
• We recommend setting messages E727, E115 and E120 to "Alarm" in the following instances:
– It is not necessary to violate the sensor range for the measuring application.
– A position adjustment must be carried out that has to correct a large measured error as a
result of the orientation of the device.
6.1 Commissioning via an FF configuration program
!
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, as well as the digital output value of
the Analog Input Block OUT, correspond to the data on the nameplate. Following a reset with
code 7864, the OUT parameter may have to be rescaled (see also Page 42, Section 6.7
"Scaling the OUT parameter").
1. Switch on the device.
2. Note the DEVICE_ID.
3. Open the configuration program.
4. Load Cff and device description files into the host system or the configuration program.
Make sure you are using the right system files.
5. Identify the device using the DEVICE_ID. Assign the desired tag name to the device by
means of the PD_TAG parameter.
