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.
F3EM2 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 a loss of synchronism between the transmitter and
receiver.

Mechanical Mounting
Please mount the light curtains in proper alignment as shown in the pictures below by using
the brackets provided with the light curtains.
For serial output models the STROBE input can be used for easier alignment. Please follow
this procedure:
• Turn on the light curtain with the STROBE input connected to +24 VDC
• Move the light curtain to reach the alignment using the led indication on receiver (see led
table 5-1)
• Turn off the light curtain and remove the +24 VDC strobe input connection
Installation
2-3 Operating environment
2-4 Operating distances
If F3EM2 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.
The operating distances, which are given in the technical specifications, are guaranteed values
for reliable operation. Operating F3EM above the specified sensing distance may cause
greater sensitivity to vibration and possible electro magnetic disturbances.
If the F3EM2 is operated in a distance <1m, the sensitivity can be set to NEAR operation by
dip-switch setting at transmitter (see ’4-1 DIP switch setting’ on page 4-2).
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.

Safety Points
F3EM2 is not a safety device. The usage of F3EM2 as Safety protection equipment is
dangerous and prohibited and expose personnel to serious injury.
The light curtain consists of an array of beams that can be obscured by an object between
transmitter and receiver. The status of each beam (open or blocked) is controlled every scan
cycle and the output reflects the current status accordingly. Thus size and position of objects
can be detected.
Different output modes are available to adapt F3EM2 operation to the given application and to
simplify installation into the machine.
3-1 Beam order
Beams are numbered in the way as shown in the picture; starting from beam 1
opposite to connector to the last beam at the connector side of the light curtain.

5-3 Beam aquisition and data aquisition
In order to understand the functions of F3EM2 and to choose the right operation mode it is
important to differentiate:
Beam acquisition = Conditions of beams checked at one scanning cycle of the light curtain.
Data acquisition = Sum of beam acquisitions gathered in the time frame between 2 external
interrogations.
The light curtain saves the beam acquisition made at each scanning cycle and executes a
logical "OR" between the status of new acquired beams and the previous one.
See an example of a data acquisition resulting from two beam acquisitions:
Operating serial output models
Triggered by an interrogation code the light curtain sends the acquired data and cleans the
beam status memory again.
1 0 0 0 0 1
1 0 0 1 0 0 1 0 1
1 0 0 1 0 1 1 0 1
1 0 0
Previous beam acq.
Last beam acq.
Data ready to be sent
In practice this process enables for example the measuring of the maximum height of an
irregular shaped object that is moving through the light curtain. Thus only the relevant
information is transmitted.
Because the beams are scanned sequentially it can occur that a command or trigger arrives
before the scan is completed. In this case the scan is interrupted and the status of the scan
before is transferred in the response protocol.
Note:F3EM2 also provides continuous bitmap transmission. In this mode the light curtain continuously
sends each beam acquisition to the host / PLC. In this case however the host has to process a much
higher amount of data.

5-4 Communication protocol for serial output
Number of bytes INT number of optical units 7+8=
5-4 Communication protocol for serial
output
The communication of the serial interface provides various possible operation modes
depending the dip-switch setting. All of them respect the following timeline:
Host sends interrogation code
F3EM2 reply with acquired data & cleans the data memory.
F3EM2 starts again with data acquisition & waits for next interrogation code
The interrogation codes can be set by dip switches 4+5 (see chapter 5-1 on page 5-2).
Note:After power-on F3EM2 starts automatically with data acquisition (without interrogation code).
The communication can also be forced by signal on the STROBE input (PNP logic); the light
curtain responds on the serial line with the desired data.
Note: This STROBE line can be used also as a check for the correctness of the serial wiring and/or
communication protocol.
The different operation modes are described below.
Bitmap of optics
Dip switch setting:
6 7 8 Type of function

The light curtain responds with a serial of bytes. The quantity of bytes depends on the total
number of beams.
Each beam status is reflected by one bit. The beam index numbers are addressed to bits as
shown in the example below. Remaining unused bits in the last byte are set to zero.
E.g. the response of a light curtain with 20 beams is 3 bytes.

When interrogation code was received the LC continuously sends out the updated bitmap of
optics every cycle time. When the light curtain receives a further interrogation code it stops
transmitting and waits for the next interrogation code to start again the transmission.

In this set-up the light curtain drives together the Serial and the analogue output.
Note:The analogue output reflects the status of the FBB and is constantly updated. The serial output, on
the contrary, transmit its data only after interrogation code receipt.
The order of bitmaps is described in ’Bitmap of optics’ on page 5-5.
Holes detection function
Dip switch setting:
6 7 8 Type of function
ON ON ON Holes detection
This function transmits the bitmap of beams with inverted bit signals.
The default setting
"0 = beam free and 1 = beam broken"
is converted into
"0 = beam occupied and 1= beam free".
Continuous bitmap
transmission
Thus without object the bitmap of all optics will show "1", if the light curtain is aligned correctly.
Acquired data reflects the sum of beam acquisitions and is sent on interrogation code as
described in 5-3 ’Beam aquisition and data aquisition’ on page 5-4.
The order of bitmaps is described in ’Bitmap of optics’ on page 5-5.
