LFP Cubic
3. Select the measuring mode
Access the EXPRT-CONFIG-MeasMd menu using the arrow and Set pushbuttons
○
HiSpd: max. length = 2,005 mm, response time < 400 ms
○
HiAcc: max. length = 6,005 mm, response time < 2,800 ms, more stable measured values,
○
recommended for liquids with low DK values and where TrsHld is < 70
4. Static sources of interference in the tank
Static sources of interference in the tank generated by tubes, beams, couplings, or a cleaning
○
ball are taught into the system as standard.
Access the EXPRT-CONFIG-CalRng menu using the arrow and Set pushbuttons.
○
The following information applies:
○
Teach-in depth starts from the LFP process connection
▫
Teach-in depth should cover all interference signals
▫
Maximum teach-in depth (recommended) = probe length
▫
Set the value range between 95 and 6,005 mm
○
If the tank cannot be emptied completely, the CalRng teach-in depth must be adapted accord-
○
ingly.
The level must be at least 200 mm below the end of the probe
○
5. Run the AutCal function
Access the AutCal menu using the arrow and Set pushbuttons.
○
The following information applies: The probe must not be covered with liquid in the CalRng
○
set in step 4 (teach-in depth + 200 mm).
Use the Set pushbutton to confirm the AutCal menu item and then use it again to confirm the
○
security question Ok?.
The AutCal function is confirmed with !CalOK.
○
6. Analyze the signal quality
The signal quality can be analyzed when the device is installed ("5.6 Evaluating signal quality")
○
In the event of problems:
○
Reduce the value in the EXPRT-CONFIG-TrsHld menu
▫
Set the parameter in the EXPRT-CONFIG-MeasMd menu to HiAcc
▫
Switch on the filter in the Set filters menu
▫
Reduce the parameter in the EXPRT-CONFIG-MaxCol menu
▫
7. Configure the filter (see Chapter "5.2 Filtering measured values")
8. Maximum change of level/plausibility check (see Chapter "5.2 Filtering measured values")
9. Configure the outputs (see Chapter 3 "Configuring the switching outputs" and "4 Configuring the
analog output")
Notes
Please use the foam commissioning instructions for applications with foam.
■
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
○
If you are encountering problems, see Chapter 7 "Troubleshooting".
