7 COMMISSIONING
Commissioning
1. Mount the sensor as appropriate to the installation conditions, see “5 Mounting” .
2. Log in to expert mode, see “8.4.1 Expert mode” .
3. Select measuring mode.
• Access the EXPRT-CONFIG-MeasMd menu using the arrow and Set pushbut-
tons.
• HiSpd: max. length = 2,005 mm, response time < 400 ms
• HiAcc: max. length = 6,005 mm, response time < 2,800 ms, more stable mea -
sured values, recommended for liquids with low DK values and where TrsHld
is < 70.
4. Teach in static sources of interference in the tank.
• Static sources of interference in the tank generated by pipes, struts, cou-
plings, or cleaning balls are taught into the system as standard.
• Access the EXPRT-CONFIG-CalRng menu using the arrow and Set pushbuttons.
Where the following applies:
• Teach-in depth starts from the LFP process connection
• The teach-in depth should cover all interference signals
• Maximum teach-in depth (recommended) = probe length
• Set the value range: 95 mm … 6,005 mm
• If the tank cannot be emptied completely, the CalRng teach-in depth must be
adapted accordingly.
• The level must be at least 200 mm under the CalLen and/or below the end of
the probe.
5. Run the AutCal function.
• Access the AutCal menu using the arrow and Set pushbuttons.
• The following 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 Ok? prompt.
• The AutCal function is confirmed with !CalOK.
6. Analyze the signal quality.
• The signal quality can be analyzed when the device is installed,
see “8.4.9 Evaluating signal quality” .
• In the event of problems:
• Reduce the value in the EXPRT-CONFIG-TrsHld menu.
• Set parameter to HiAcc in the EXPRT-CONFIG-MeasMd menu.
• Switch on filters in the Set filters menu.
• Reduce the parameter in the EXPRT-CONFIG-MaxCol menu.
7. Configure the filter (see “8.4.2 Filtering measured values” ).
8. Run maximum change of level / plausibility check
(see “8.4.2 Filtering measured values” ).
9. Configure the outputs (see “8.2 Configuring the switching outputs” ).
