1.8 Shortening the probe

If the mono-probe is too long for use, it can be shortened to the height of the container. In this case,
you should not shorten the probe beyond its minimum length of 100 mm. If the LFP is to be used
in a hygienic application, then be sure that the roughness of Ra<= 0.8 µm is reestablished on the
shortened machined surfaces of the mono-probe.
Procedure:
Shortening the probe rod to the desired dimension. Set the new probe length in the LFP as described
in Chapter 5.3 "Configuring the probe length". Please ensure that this adjustment matches the
length of the probe, since an incorrect value in the Length menu has a direct effect on measurement
accuracy and can lead to malfunctions. The probe length L is defined in Chapter 9.8
"Dimensional drawings".
2 Commissioning the LFP
2.1 Quick commissioning (with factory settings)
Quick commissioning is used in applications under reference conditions (see chapter 1.4
"Installation conditions").
The following information applies:
Use in metallic containers or immersion/bypass tubes
■
Use in a plastic tank with a coaxial tube (see chapter 10 "Accessories")
■
Situations where the liquid to be measured has a DK value of > 5 (see chapter 14 "Medium list")
■
Commissioning
1. Mount the sensor according to the installation conditions (see chapter 1.4 "Installation conditions"
and 1.7 "Mounting the coaxial tube").
2. The container should be empty and/or the liquid should be at least 200 mm below the probe end.
3. After mounting, launch the AutCal menu item.
Press and hold the Set pushbutton for at least 3 secs.
○
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.
○
4. Configure the outputs (see Chapter 3 "Configuring the switching outputs" and Chapter 4
"Configuring the analog output").
Note: If the AutCal function has been confirmed with !NoSig, relaunch AutCal.
If you are encountering problems, see Chapter 7 "Troubleshooting".
2.2 Advanced commissioning
Advanced commissioning is required when quick commissioning is not sufficient or if one of the
following situations applies:
