COMMISSIONING
Commissioning
1. Mount the sensor in accordance with the installation conditions, see
.
2.
Log in to expert mode, see
3. Select the measuring mode.
•
Access the EXPRT-CONFIG-MeasMd menu using the arrow and Set pushbuttons.
•
HiSpd: max. length = 2005 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 DKs and where
TrsHld is < 70.
4. Teach-in the 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 rules apply:
•
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 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 below the CalLen and/or the end of the
probe.
5. Launch 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 “Ok?” confirmation 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 the parameter to HiAcc in the EXPRT-CONFIG-MeasMd menu.
•
Switch on the filters in the Set filters menu.
•
Reduce the parameter in the EXPRT-CONFIG-MaxCol menu.
7.
Configure the filter (see Chapter
“8.4.2 Filtering measured values”
).
8.
Perform maximum change of level/plausibility check
(see Chapter
“8.4.2 Filtering measured values”
9.
Configure outputs (
“8.2 Configuring the switching outputs”
).
