• The sensor automatically quits expert mode after 5 minutes of inactivity on the
display.
•
Configuration (AutCal) does not take place in the following processes:
• Changing the probe length
• Changing the measuring mode
• Changing the teach-in depth
For problems during commissioning, see
7.3
Foam commissioning (with factory settings)
For use in applications with a significant buildup of foam.
Performing foam calibration
1. Mount the sensor as appropriate to the installation conditions, see
2. Log in to expert mode, see
3. Empty the tank completely.
•
The probe rod must be completely free from medium and foam.
•
Buildup must be removed from the probe.
•
The end of the probe must not be fixed to the bottom of the tank.
4. Select measuring mode.
•

ure to Foam.
6. Perform empty calibration.
•
Access the EXPRT-Foam-CalEmp menu using the arrow and Set pushbuttons.
•
!CalOk: proceed to step 7.
•
!faild: Make sure the tank is empty and repeat step 6.
7. Fill with medium (without foam) until the probe is covered by at least 200 mm. The
maximum level must remain 200 mm from the process connection, however.
8. Run EXPRT-Foam-CalMed.
•
!CalOk: Everything worked, proceed to step 9.
•
!faild: Repeat step 8.
The LFP should now display a valid measured value.
9. Check the foam calibration in EXPRT-INFO-CalSta.
•
FomCal: Foam commissioning was completed successfully.
