8 Commissioning
8.1 Preliminaries
The measuring range and the unit in which the measured value is transmitted correspond
to the data on the nameplate.
L
WARNING
Process pressure above or below permitted maximum/minimum!
Risk of injury if parts burst! Warnings are displayed if the pressure is too high.
‣
If a pressure smaller than the minimum permitted pressure or greater than the
maximum permitted pressure is present at the device, a message is output.
‣
Only use the device within the sensor range limits!
8.1.1 As-delivered state
If no customized settings were ordered:
• Calibration values defined by defined sensor nominal value
• The alarm current is set to min. (3.6 mA), (only if no other option was selected when
ordering)
• DIP switch to Off position
8.2 Function check
Perform a function check before putting the measuring point into operation:
• "Post-installation check" checklist (see the "Installation" section)
• "Post-connection check" checklist (see the "Electrical connection" section)
8.3 Device configuration
8.3.1 Commissioning with keys on the electronic insert
The following functions are possible via the keys on the electronic insert:
• Position adjustment (zero point correction)
The orientation of the device may cause a pressure shift
This pressure shift can be corrected by a position adjustment
• Setting lower range value and upper range value
The pressure applied must be within the nominal pressure limits of the sensor (see the
specifications on the nameplate)
• Resetting the device
Carrying out position adjustment
1. Device installed in desired position and no pressure applied.
2. Press the "Zero" and "Span" keys simultaneously for at least 3 s.
3. When the LED lights up briefly, the pressure present has been accepted for position
adjustment.
Setting the lower range value (pressure or scaled variable)
1. Desired pressure for lower range value is present at device.
2. Press the "Zero" key for at least 3 s.
3. When the LED lights up briefly, the pressure present has been accepted for the lower
range value.
