2. Target Group, Personnel

Responsibility for planning, assembly, commissioning, operation,
maintenance, and dismounting lies with the plant operator.

The personnel must be appropriately trained and qualified in order to carry
out mounting, installation, commissioning, operation, maintenance, and
dismounting of the device. The trained and qualified personnel must have
read and understood the instruction manual.

Prior to using the product make yourself familiar with it. Read the
instruction manual carefully.

3. Reference to Further Documentation

Observe laws, standards, and directives applicable to the intended use
and the operating location.

The corresponding datasheets, manuals, declarations of conformity, EU­type examination certificates, certificates, and control drawings if
applicable supplement this document. You can find this information under
www.pepperl-fuchs.com.

If you use the device in safety-related applications, observe the
requirements for functional safety. You can find these requirements in the
functional safety documentation under www.pepperl-fuchs.com.

7. Operation, Maintenance, Repair

If you operate the device in safety-related applications, observe the
requirements for functional safety. For the proof test, plan appropriate
intervals for the operation in low demand mode.

Do not use a damaged or polluted device.
Do not repair, modify, or manipulate the device.
If there is a defect, always replace the device with an original device.

Disconnect the device, before you plug or unplug the terminals.
Disconnect the device, before you plug or unplug the plugs.
Take measures to prevent that the supply voltage exceeds 40 V DC in the

case of a fault. Use a suitable power supply.

8. Delivery, Transport, Disposal

Check the packaging and contents for damage.
Check if you have received every item and if the items received are the

ones you ordered.
Keep the original packaging. Always store and transport the device in the

original packaging.
Store the device in a clean and dry environment. The permitted ambient

conditions must be considered, see datasheet.
The device, built-in components, packaging, and any batteries contained

within must be disposed in compliance with the applicable laws and
guidelines of the respective country.

4. Intended Use

The device is only approved for appropriate and intended use. Ignoring
these instructions will void any warranty and absolve the manufacturer
from any liability.

The device is an inductive sensor (proximity sensor). If an electrical
conductive object, also known as a measuring plate, is inside the sensing
range of the sensor coil, the magnetic field of the coil is influenced and an
electrical switching signal is generated. The device can be operated in
3-wire or 4-wire circuits.

The device has 2 OSSD outputs with normally open function. The outputs
switch to the off state according to their defined behavior under fault
conditions (PDDB). If there is no object inside the sensing range, the
outputs are high-impedance (off state). These outputs are compatible with
the digital input types 1, 2 or 3 according to IEC/EN 61131-2.

The device transmits the digital signal to a safety PLC.
Use the device only within the specified ambient and operating conditions.
Only use the device stationary.
If you use the device in safety-related applications, observe the

information for safety function and safe state.

5. Improper Use

Protection of the personnel and the plant is not ensured if the device is not
used according to its intended use.

6. Mounting and Installation

Do not mount a damaged or polluted device.
If you install the device in safety-related applications, observe the

requirements for functional safety.
Observe the tightening torque of the device nuts.
Recommended tightening torque

Minimum tightening torque over the full thread length of the cylindrical
sensor

Type Brass Stainless steel

NS*-12G... 10 Nm 15 Nm

NS*-18G... 30 Nm 30 Nm

NS*-30G... 30 Nm 30 Nm

Take measures to prevent electrical conductive material, with the
exception of the designated measuring plate, is placed near the active
area.

Observe the installation conditions for mounting the device.
Protect you from electric shock. Only connect the device to power supplies

with parameters comply to the specifications in the datasheet.
