3.2.2 Operating buttons

The sensor is operated using the display and operating buttons.
For a detailed description of the pushbuttons and their functions, see “8.1 Display and
pushbuttons”.

3.3 Product features and functions

3.3.1 Principle of operation

The LFP uses TDR (Time Domain Reectometry) technology.
This is a process to determine transit times of electromagnetic waves. The sensor electronics generate a low-energy electromagnetic pulse, which is linked to and runs along the probe.
If this pulse strikes the surface of the liquid to be measured, a portion of the pulse
is reected there and is conducted back up along the probe path to the electronics, which then calculate the level based on the time dierence between the sent and the
received pulse.
The sensor can output this level as a continuous measured value (analog output) and can also derive two and/or four freely positionable switching points from it (switching outputs).
IO-Link communication is also available for the switching output (Q1), see “8.1.3 IO-Link”.

3.3.2 Fields of application

The innovative TDR technology enables reliable level measurement which is largely application-independent. The LFP is suitable for both continuous level measurement and point level measurement in nearly all liquids.
The sensor is not aected by changes in the properties of the liquids to be measured.
The LFP can be used in metal containers or bypass/immersion pipes. A coaxial tube is
required for use in plastic containers.

5 Mounting
B

5.1 Installation conditions

The LFP is mounted vertically from above into the container or bypass, using its process connection. The LFP level sensor has a G ¾ or ¾" NPT threaded connection. A minimum connecting piece diameter in accordance with the diagrams below must be observed.
The LFP must be installed so that after mounting there is sucient distance to other tank
components (e.g. supply tubes, other measurement devices), the container wall or the
container bottom. These minimum distances are also specied in the diagrams.
The LFP can also be used in a metal immersion pipe or bypass. The installation conditions are shown in the Figure on page 15.
Ensure that there is a good metallic connection between the LFP measuring device and the tank/bypass. When operating the sensor, ensure that the ambient temperature is not above or below the limits.
Insulating the sensor housing is not permitted for tanks with hot media.
When positioning the device, ensure that the sensor is not directly exposed to the lling ow.
The sensor housing can be rotated 360°, allowing for the cable outlet to be positioned freely.

5.2 Mounting the coaxial tube

See the operating instructions for the coaxial tube (8015674) at www.sick.com.

5.3 Shortening or replacing the probe rod/rope probe

If the probe rod or rope probe is too long for the application, it can be shortened to the container height. 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.

5.3.1 Procedure

Shorten the probe rod and/or rope probe as desired. Adjust the new probe length in the LFP, see “8.4.7 Conguring the probe length”. Ensure that this correction corresponds
to the probe length, because an incorrect value in the Length menu has a direct eect
on measurement accuracy and can lead to faults. The probe length L is set out in Chapter “15 Dimensional drawings”.
The probe rod and/or the rope probe can be swapped. Use a suitable tool. If the system
experiences strong vibrations, secure the probe with thread-locking lacquer.

Only switch on the supply voltage for the device when the connection tasks have been completed and the wiring has been thoroughly checked.
When using extension cables with open ends, ensure that bare wire ends do not come into contact with each other (risk of short-circuit when supply voltage is switched on!). Wires must be appropriately insulated from each other.
Wire cross-sections in the supply cable from the customer's power system must be designed in accordance with the applicable standards. In Germany, observe the following standards: DIN VDE 0100 (Part 430) and DIN VDE 0298 (Part 4) and/or DIN VDE 0891 (Part 1).
Circuits connected to the device must be designed as SELV circuits
(SELV = Safety Extra Low Voltage).
Protect the device with a separate fuse at the start of the supply circuit.
Instructions for laying data cables:
• Use screened data cables with twisted-pair wires.
• Implement the screening design correctly and completely.
• To avoid interference, e.g. from switching power supplies, motors, clocked drives,
and contactors, always use cables and layouts that are suitable for EMC.
• Do not lay cables over long distances in parallel with voltage supply cables and
motor cables in cable channels.
Subject to change without notice
The IP67 protection class for the device is only achieved under the following conditions:
The cable connected at the M12 connection is screwed on.
If this is not done, the device does not fulll any specied IP enclosure rating!
