Precautions

WARNING

The F3ET2 multi-beam photoelectric sensor with beam evaluation function is not a safety
component for ensuring the safety of people which is defined in EC directive (2006/42/EC) or
by any other regulations or standards.

GENERAL INFORMATION

The instructions in this manual must be followed in order to safeguard correct installation. The
barrier does not contain any parts that are subject to maintenance; do not remove any
electronic parts from the housing for any reason. In case of malfunction, please contact your
sales representative with a description of the failure found and its period of operation. Do not
touch the front protective cover with your hands as dust and/or grease may decrease
performance.

Precautions

OPERATING ENVIRONMENT

Do not use the light curtain in locations with explosive or flammable gas. Make sure that the
product is operated in accordance with IP65 standards. Do not subject the light curtain to
excessive shock when mounting. When using the light curtain in the vicinity of an inverter
motor, be sure to connect the protective earth ground wire of the motor to earth. Failure to
ground the motor may result in malfunction of the light curtain. Further it is recommended to
use shielded cables and to connect the shield to the ground in such cases.

CLEANING

When cleaning the front covers please do not use woollen cloths or organic solvents. The
interval between cleaning depends on conditions in the environment (dust, fog).

POWER SUPPLY VOLTAGE AND OUTPUT LOAD

Do not connect an AC power supply to the Sensor. If AC power (100 VAC or more) is supplied
to the Sensor, it may explode or burn. Make sure that the power supply to the Sensor is within
the rated voltage range. If a voltage exceeding the rated voltage range is supplied to the
Sensor, it may explode or burn.

Overview

F3ET2 is a multi-beam light curtain for easy area detection for various applications. Due to its
robust housing F3ET2 is also suitable for hash environments in industrial automation.

F3ET2 is provided with PNP and NPN transistor output.

F3ET2 is available in two resolutions:

Model Sensing distance Pitch resolution Min. detectable object

F3ET2-005-[…] 0 to 3 m 5 mm 10 mm

F3ET2-018-[…] 0 to 15 m 18 mm 30 mm

Models with 7.5 mm resolution are available upon request.

Due to its modular design F3ET2 can be provided in various sizes. For standard sizes please
refer to model list in chapter 3.

2-1 General

2-1 General

The light curtain consists of one bar with light emitting optical elements and of one with
receiving optical elements. The photosensitive elements are scanned in sequence, thus
broken rays are detected.

F3ET2 features optical synchronisation and does not require synchronization wire between
transmitter and receiver. The sync-function is provided by the upper beam located on the
opposite side of the connector (see illustration below). During operation this beam must always
be kept free. Otherwise it will result in a longer response frequency of the light curtain.

Mounting accessories

The F3ET2 system is mechanically installed by using the T-slots on the two sides or the back­side of the housing.
Use the movable bolts, washers, growers and nuts to fix the mounting brackets as shown in
the picture

Note: Shipment contains different quantity of brackets, depending on the length of the LC. Longer LC

contains a higher number of brackets, following the rule of every 400 mm one bracket.

Additional mounting rigidity

It is recommended that the distance between the mounting brackets is 400 mm or less for
optimum performance of the F3ET2 system.

Mechanical Mounting

Please mount the light curtains in proper alignment as shown in the pictures below by using

2-3 Operating environment

Installation

If F3ET2 is installed at long distances the laser alignment aid F39-TGR-LLK2-CL provides a
visible laser spot for simplified installation.
If several light curtains are installed close to each other, interference of the light curtains must
be avoided. In this case the assembly should be carried out as follows:

TX TXRXRX

The area for the installation of the light curtain must be suitable according to the technical
specifications. The temperature of the environment, interference caused by electromagnetic
disturbance and ambient light must be considered. Please contact the manufacturer for any
information not contained in this manual.

2-4 Operating distances

The operating distances, which are given in the technical specifications, are guaranteed values
for reliable operation. Operating F3ET2 above the specified sensing distance may cause
greater sensitivity to vibration and possible electromagnetic disturbances.

If the F3ET2 is operated in a distance <1m, the sensitivity can be set to NEAR operation by
dip-switch setting at transmitter (see ’ DIP switch setting’ on page 2-7).
This should be considered for following application conditions:

a) Multiple light curtains are installed close to each other (avoiding mutual interference)
b) Detection of small or semi-transparent objects

If none of above mentioned cases applies, FAR setting should be kept in order to provide
maximum detection reliability.

To access the selector switches unscrew the end cap of the receiver and transmitter unit:

Installation

There are two lines of dip switches in each transmitter and receiver. The settings must
be done for both lines. Change the setting of the dip-switch and close the cap again. The light

curtain can now be reconnected to the power supply.
