Performing position adjustment on site
• Operation must be unlocked.
• The device is configured for the "Pressure" measuring mode (Cerabar, Deltabar) or "Level"
measuring mode (Deltapilot) as standard.
Operation via FF configuration program: In the Pressure Transducer Block, you can change
the measuring mode by means of the PRIMARY_VALUE_TYPE parameter.
• The pressure applied must be within the nominal pressure limits of the sensor. See
information on the nameplate.
• To reconcile the parameter database, perform a "Reconcile device" (after position
adjustment) with the FF host.
Perform position adjustment:
1. Pressure is present at the device.
2. Press key for at least 3 seconds.
3. If the LED on the electronic insert lights up briefly, the pressure applied has been
accepted for position adjustment. If the LED does not light up, the pressure applied was
not accepted. Observe the input limits. For error messages see the Operating
Instructions.
