Commissioning
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.
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
• 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.
7.2
Function check
Carry out a post-installation and a post-connection check as per the checklist before
commissioning the device.
• "Post-installation check" checklist
• "Post-connection check" checklist
7.3
Commissioning via an FF configuration program
• 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 (79, Section 7.9
• The standard order configuration is illustrated on
40, Section 6.3.6 "Deltabar S block
1. Switch on the device.
2. Note the DEVICE_ID.
40, Section 6.3.5 "Device identification and addressing" and
10, Section 3.2.1 "Nameplates" for the device serial number.
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.
