Product description
4.2 Characteristics and features
• Threaded tube M18 × 1 or M30 × 1.5
• Embedded installation
• Plastic, PA12-GF30, PEI
• Configuration via IO-Link, teach button or manual bridging (pin 5, please use 5-wire cable for this
purpose)
4.3 Operating principle
The sensors are used to detect the fill levels of liquids or bulk materials – either in direct contact with the
medium or also through a non-metallic container wall. The capacitive sensors are also able to detect both
metallic (electrically conductive) and non-metallic (electrically non-conductive) objects contactless and free
from wear.
4.4 Functions and operating modes
In its delivery state, the device behaves like a proximity switch with a rated switching distance of 5mm
(LCS-1M18P-...-LT) or 10mm (LCS-1M30P-...-LT). Additional functions can be taught by the user.
4.4.1 Conguration options
The devices can be configured via IO-Link using Sensor Studio.
The capacitive sensors have other configuration options:
• Configuration via manual bridging of pin 5 to UBor pin 5 to GND
• Configuration via buttons
4.4.2 "Medium present" mode (full teach)
In the "Medium present" mode (full teach), the device operates with the lowest possible sensitivity. Possible
uses are applications with easily detectable media. In this case, a switching point is taught when a medium or
an object is in the detection range of the sensor.
The switching threshold is set for the "Medium present" mode automatically so that a safety reserve relative
to the switch-off limit is provided. The safety reserve can be configured via FDT/IODD. The switching point is
below the measured capacitance. In the "Medium present" mode, environmental influences such as tempera-
ture fluctuations, condensation, film formation or soiling have little effect on the signal. The switching point
can be configured using the "Medium present" teach. The time interval between two teach events can be any
length.
4.4.3 "Medium not present" mode (empty teach)
In the "Medium not present" mode (empty teach), the device operates with maximum sensitivity. Possible uses
are e.g. applications in which pre-actuation due to environmental influences is to be avoided. The switching
point is taught when no medium or object is in the detection range of the sensor.
The switching threshold is set for the "Medium not present" mode automatically so that a safety reserve relative
to the switch-off limit is provided. The safety reserve can be configured via FDT/IODD. The switching point is
above the measured capacitance. In the "Medium present" mode, environmental influences such as tempera-
ture fluctuations, condensation, film formation or soiling have little effect on the signal. The switching point can
be configured using the "Medium not present" teach. The time interval between two teach events can be any
length.
4.4.4 "Switching point between medium present and medium not present" mode (complete teach)
The "Switching point between medium present and medium not present" mode is suitable for applications
with difficult environmental conditions or media with little contrast. In this case, the teach events "Medium
present" and "Medium not present" are performed one after the other. The switching point is midway between
the capacitances measured for the two teach events.
In the "Switching point between medium present and medium not present" mode, a difference between the
full and empty state of a container can be detected.
4.4.5 Internal voltage and temperature monitoring
The device has internal voltage and temperature monitoring. The monitoring functions allow assessment of the
load on the sensor and of the sensor's failure probability.

Mounting
5 Mounting
The sensors can be mounted in any position (orientation). The maximum tightening torque for mounting the
sensor is 2Nm (LCS-1M18P-...-LT) or 5Nm (LCS-1M30P-...-LT).
➤ Clean the mounting surface and mounting environment.
➤ If a mounting aid is used: Secure the sensor in the mounting aid.
➤ Mount the sensor or the mounting aid at the intended operating location.
➤ Make sure that the connector on the rear of the sensor remains accessible.
➤ Observe the minimum mounting distances.

Distance D 36 mm 60 mm
Distance W 15 mm 30 mm
Distance S 27 mm 45 mm
Distance G 30 mm 60 mm
Abb. 3: Minimum mounting distances
➤ If more than one sensor is used in the application: Avoid overlapping of the electrical fields. Overlapping
can occur if two sensors are mounted closer than 36mm (LCS-1M18P-...-LT) or 60mm (LCS-1M30P-...-LT) to
each other.

The capacitive sensor has a switching output with adjustable switching point. After a successful teach event,
the sensor operates automatically in normal operation. The time interval between two teach events can be any
length.

Eliminating faults
10 Eliminating faults
If the device does not function as expected, first check whether any environmental interference is present. If
there is no environment-related interference, check the connections of the device for faults.
If no faults are found, the device is defective. In this case, take the device out of operation and replace it with a
new device of the same type.
11 Maintenance
The connectors and cables must be checked regularly to ensure that they are in good condition.
The devices do not require maintenance; clean with a damp cloth as required.
12 Repair
The device is not designed to allow repair by the user. If the device is defective, take it out of operation and
return it to Leuze electronic. Here it is important to observe the specific warranty conditions agreed upon with
delivery of the product.
13 Decommissioning
➤ Disconnect the interconnection cable from the power supply and/or evaluation units.
➤ Disconnect the interconnection cable from the sensor.
➤ Detach the sensor or, if applicable, the mounting aid from the installation environment.
➤ If applicable, detach the sensor from the mounting aid.
14 Disposing
The devices must be disposed of properly; they do not belong in ordinary household waste.
