Notes
Please use the foam commissioning instructions for applications with foam.
■
The sensor ends expert modes automatically 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

If you are encountering problems, see chapter 7 "Troubleshooting".

2.3 Foam commissioning (with factory settings)

For use in applications with a significant buildup of foam.
Performing foam calibration
1. Mount the sensor according to the installation conditions (see chapter 1.4 „Installation conditions"
and 1.7 „Mounting the coaxial tube")
2. Log in to expert mode (Please see „5.1 Expert Mode")
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 the measuring mode
Access the EXPRT-CONFIG-MeasMd menu using the arrow and Set pushbuttons, and configure
○
to HiAcc.
5. Perform empty calibration
Access the EXPRT-FOAM-CalEmp menu using the arrow and Set pushbuttons.
!CalOk: proceed to step 6.
○
!faild: Ensure that the tank is empty and repeat step 5.
○
6. Pour in the medium (without foam) until the probe is covered by at least 200 mm, but up to a
maximum level of 200 mm away from the process connection.
7. Adjust the sensitivity
For exiting the EXPRT-menu use the ESC-pushbutton. The LFP has to show a valid measuring value.
Adjust the TrsHld value in EXPRT-CONFIG-menu in case of an invalid measuring value.
Access the EXPRT-CONFIG-TrsHld menu using the arrow and Set pushbuttons. The following infor-
mation applies:
50 % = high sensitivity
○
100 % = standard
