3 For your safety
The product is designed according to state-of-the-art technology. However, residual risks still
exist. Observe the following warnings and safety notices to prevent damage to persons and
property. Turck accepts no liability for damage caused by failure to observe these warning and
safety notices.
3.1 Intended use
The capacitive limit level sensors from the NCLS product series monitor the filling level of differ-
ent types of media (liquid, viscous, granular, powder form) in containers and pipes by creating
contact with the media. The hygienic process connection, the PEEK sensor tip, the stainless
steel housing and the M12 connector allow the limit level sensor to be used in various applica-
tions, including applications in the food and pharmaceutical industries. The device can be ex-
posed to process temperatures of between 0…100 °C (130 °C < 1 h) and a process pressure of
up to 1 bar.
The devices may only be used as described in these instructions. Any other use is not in accord-
ance with the intended use. Turck accepts no liability for any resulting damage.
3.2 General safety instructions
nThe device meets the EMC requirements for industrial areas. When used in residential areas,
take measures to avoid radio interference.
nThe device may only be assembled, installed, operated, parameterized and maintained by
professionally-trained personnel.
nThe device may only be used in accordance with applicable national and international regu-
lations, standards and laws.
nThe devices may only be used in metal containers. When used in non-metallic containers,
measures must be taken to meet the requirements of the EMC Directive 2014/30/EU.
nThe maximum permissible values for process pressure and process temperature must not be
exceeded.

4 Product description
The capacitive limit level sensors of the NCLS series are contained in a stainless steel housing
with a PEEK sensor tip. The devices are provided with a metal M12 male connector for connect-
ing the sensor cable. An IO-Link interface is provided for setting and operating the devices. The
devices are provided with two outputs that can be set independently of each other. Output 1
can be used as a switching output or in IO-Link mode as required.

4.3 Operating principle
Capacitive sensors measure wear-free metallic (electrically conductive) and non-metallic (elec-
trically non-conductive) objects. When in direct contact with the media, the NCLS limit level
sensors are able to detect and differentiate different substances in liquid, viscous, granular or
powder form. Typical application areas are the detection of limit levels (max./min.) and changes
in media in tanks and pipes.
4.4 Functions and operating modes
The NCLS limit level sensor operates on the basis of the capacitive measurement principle.
When immersed, the active surface of the switch detects whether the medium is present or not.
The device is also able to differentiate between different media. The limit level sensor is
equipped with two parametrizable switching outputs. One of the switching outputs can be
used as an IO-Link interface, thus enabling direct access to the process values and parameters
of the device during normal operation. The device can only be parameterized via IO-Link.

NOTICE
Mounting without or with the wrong process adapter
Material damage caused by leaking connection
Always mount the sensor with the process adapter.
Only use a Turck process adapter for the process connection.
A Turck process adapter must be used for the process connection. The process adapter is avail-
able as a clamp adapter, welding adapter or screw-in adapter.
Fig.2: Process connection with Turck process adapter
5.1 General mounting instructions
nIn principle, the sensor can be installed in any position and in any location.
nAvoid mounting positions in which highly adhesive or viscous media may create deposits.
nAvoid mounting positions in which air pockets may be created.
nEnsure that the minimum distance of at least 15 mm is maintained between the sensor tip
and any adjacent objects (e.g. the wall of a container or pipe).
nThe relative permittivity (εr) of the medium must be >1.5.

12 Hans Turck GmbH & Co. KG | T [phone] | F [phone] | [email protected] | www.turck.com
5.2 Mounting the sensor with the process adapter
The sensor is equipped with a G1/2” thread and is self-sealing when used in combination with
the process adapter. An additional seal is not necessary.
Before assembly, ensure that the system has been depressurized and that there is no me-
dia in the pipe or container.
Mount the process adapter on the tank/pipe, ensuring that it is fully sealed.
Screw the sensor into the Turck process adapter.
Use a wrench to tighten the sensor (tightening torque: 20 Nm).
5.3 Mounting the sensor in hygienic applications according to EHEDG
The sensor is certified for use in hygienic applications in accordance with EHEDG.
Integrate the sensor in the plate in accordance with EHEDG requirements.
Only use an EHEDG-compliant process adapter for mounting.
Install the sensor so that there is no dead space. Observe the following dimensions to
avoid dead space: L < (D-d)

Fig.4: Avoiding dead space and installing a leakage hole (A)
Install a self-draining sensor.
Choose an installation in the tank so that the sensor is fully accessible from the cleaning
ports.
Install the leakage hole (A) so that it is clearly visible. When using vertical cables, the leak-
age hole must face downward.

8 Operation
8.1 LEDs
LED Meaning
Green Switching state of output 1, indication function adjustable:
nLit if output 1 (OUT1) is active
nLit if output 1 (OUT1) is inactive
The LED ignores the set delay in both cases and switches immedi-
ately. The switching state of output 2 (OUT2) cannot be indicated
via an LED.
Green flashing Process value within the set hysteresis

V01.01 | 2022/06 17
9 Setting
The device can only be parameterized via IO-Link. The following settings are possible for each
output:
nOutput type: PNP, NPN, push-pull
nOutput function: NO contact (NO), NC contact (NC), pulse width modulation (PWM)
nSwitching hysteresis (at least 2 %)
nTime delay for the switching signal
Parameter setting via IO-Link is explained in the IO-Link commissioning manual.

Troubleshooting
18 Hans Turck GmbH & Co. KG | T [phone] | F [phone] | [email protected] | www.turck.com
10 Troubleshooting
If the device does not function as expected, first check whether ambient interference is present.

11 Maintenance
The device is maintenance-free. Clean with a damp cloth if required.
12 Repair
The device must not be repaired by the user. The device must be decommissioned if it is faulty.
Observe our return acceptance conditions when returning the device to Turck.
12.1 Returning devices
Returns to Turck can only be accepted if the device has been equipped with a Decontamination
declaration enclosed. The decontamination declaration can be downloaded from
