Operation
The F3EM measuring lightcurtain features optical synchroniza-
tion. This function is provided by the upper beam located on the
opposite side of the connector (see illustration below). During op-
eration this beam must always be kept free. Otherwise it will result
a loss of synchronism between the transmitter and receiver.
For applications where all beams are interrupted there are special
models with synchronization by wire. Please contact your
OMRON representative.
Indicator LEDs
For functions of indicator LEDs please refer to the tables be-
low:
Selector switches (dip switches)
Operation mode, distance setting (analog models) and trans-
mission speed (serial models) can be changed by selector
switches. To access selector switches unscrew the end cap
of the receiver unit:
Note: Selector setting must only be carried out when the receiver is not con-
nected to the power supply.

Analog Output Models (F3EM-_-AV)
DIP Switch Settings
If F3EM is operated in a distance < 1m, the sensitivity can be
set to NEAR operation. This could be necessary, if multiple
light curtains are installed close to each other, or if the light
curtain detects semi-transparent objects.
The analog output can operate either in STANDARD mode or
INVERTED mode:
• STANDARD mode: 0 V (if no beams is interrupted) to 10 V
(if all beams are interrupted)
• INVERTED mode: 10 V (if no beams is interrupted) to 0 V
(if all beams are interrupted)
Please find the DIP switch setting below:
Analog output value
The output value is related linear to the number of beams in-
terrupted by the object to be measured. For STANDARD
mode:
Output voltage = (10/ n° of optical units) * n° of interrupted
beams [VDC]
If multiple objects are inside the sensing area, the system will
read the total number of beams interrupted accordingly. Re-
ferring to the illustration below, the F3EM provides an output
signal in proportion with the sum of A+B:
Serial Output Models - RS232 (F3EM-_-D2)
The RS232 serial interface of F3EM is specified as follows:
• Full duplex operation
• Data format: 8-N-1 (bit start - 8-bit data - 1-bit stop - no
parity)
Transmission speed setting (Baud Rate)
The baud rate can be set by DIP switch 1 and 2.
@The baud rate must be set both on the receiver bar
dip-switches as well as the transmitter bar dip-switch-
es to align the timing synchronism of the two bars.
Communication protocol
The communication of serial interface provides two possible
operation modes:
• Command-response
• Triggered by external input
A) In command-response mode the command is 1 byte:
Command (hexadecimal) = 'BF'
The light curtain responds with a fixed number of bytes de-
pending on the number of light beams.
E.g. the response of a light curtain with 20 beams is 3 bytes:
The response bytes are composed by each bit representing
the status of each beam in the order as in the example above.
Remaining unused bits in the last byte are set to zero.
Each bit signals:
0 = BEAM NOT INTERUPTED
1 = BEAM INTERRUPTED
This drawing shows how the beams
are numbered on the light curtain
As a result each response byte contains 8 beams. The follow-
ing formula applies for the calculation if the number of re-
sponse bytes:
number of bytes = INT (number of optical units + 7) / 8)
The maximum number of optical beams that can be managed
is 400.
B) Trigger by external input
Alternatively the response can be forced by signal on the
STROBE input (PNP logic); the light curtain responds on the
serial line with the same protocol explained above.
Measurement method
In order to avoid missing information the light curtain stores in-
terruption of beam signals until the status is sent in the next
protocol response. After the response is sent the interruption
status is reset (all bits to zero).
The beams are scanned sequentially. Therefore it can occur
that a command or trigger arrives before the scan is complet-
ed. In this case the scan is interrupted and the status of the
scan before is transferred in the response protocol.

Mounting
Mechanical attachment and alignment
Standard Mounting Bracket (provided with the sensor)
When the mounting bracket is attached to the surface, the mounting
screws can be inserted into the mounting rail of the light curtain. This
allows a vertical position adjustment.
Adjustable Mounting Bracket
Order separately under: F39-TGR-ST-ADJ
For adjustment of the optical axis angle, the adjustable mounting
bracket allows a turning of the light curtain.
Laser Alignment
Order separately under: F39-TGR-LLK2-SB
The laser alignment kit can be snapped onto the light curtain and
emits a high visibility laser beam for ensuring the optimal optical axis
angle adjustment.
Cable connectors
For pin arrangement and connecting the wires refer to Output Circuits.

Precautions
Power Supply Voltage and
Output Load Power Supply Voltage
Do not connect an AC power supply to the Sensor. If AC pow-
er (100 VAC or more) is supplied to the Sensor, it may ex-
plode 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.
Operating Environment
Do not use the sensor in locations with explosive or flamma-
ble gas. Make sure that the product is operated in accordance
with IP65 standards.
Do not subject the sensor to excessive shock when mounting.
When you use the sensor in the vicinity of an inverter motor,
be sure to connect the protective earth ground wire of the mo-
tor to earth. Failure to ground the motor may result in malfunc-
tion of the sensor.
Mounting the Sensor
Do not strike the sensor with a hammer or any other tool dur-
ing the installation of the Sensor.
Cleaning
Never use paint thinners or other organic solvents to clean the
surface of the product
M12 Connector
Always turn OFF the power supply to the sensor before con-
necting or disconnecting the metal connector. Hold the con-
nector cover to connect or disconnect it.
Secure the connector cover by hand. Do not use pliers; other-
wise the connector may be damaged.
If the connector is not connected securely, it may be discon-
nected by vibration or the proper degree of protection of the
sensor may not be maintained.
@WARNING
The F3EM multi-beam photoelectric sensor with beam
evaluation function is not a safety component for en-
suring the safety of people which is defined in EC di-
rective (2006/42/EC) or by any other regulations or
standards.
