SAFETY INFORMATION
The following points must be observed for a correct and safe use of the safety light curtains of the SG4
FIELDBUS series:
The stopping system of the machine must be electrically controlled.
This control system must be able to stop the dangerous movement of the machine within the total machine stopping
time T as per cfr. 1.3 of the Instruction Manual and during all working cycle phases.
Mounting and connection of the safety light curtain must be carried out only by qualified personnel, according to the
indications included in the special sections (refer to cfr. 2; 3; 4; 5) and in respect to the applicable Standards.
The safety light curtain must be securely installed so that access to the dangerous zone is not possible without
interrupting the beams.
The personnel operating in the dangerous area must be well-trained and must have adequate knowledge of all the
operating procedures of the safety light curtain.
Please carefully read the instructions for the correct functioning before powering the light curtain.

QUICK GUIDE
Precautions to be observed for the choice and installation of the device
Make sure that the protection level assured by the SG4 device (Type 4) is compatible with the real danger
level of the machine to be controlled, according to EN ISO 13849-1 and EN 62061.
The dimension of the smallest object to be detected must be larger than the resolution level of the device.
The ESPE must be installed in a room complying with the technical characteristics indicated in cfr. “Technical data” of
the Instruction Manual.
Do not place the device near intense and/or flashing light sources and, in particular, close to receiving unit front surface.
The presence of intense electromagnetic disturbances could jeopardise device operation. This condition has to carefully
evaluated with the support of the Datalogic Technical service.
The operating distance of the device can be reduced in presence of smog, fog or airborne dust.
A sudden change in environment temperature, with very low minimum peaks, can generate a small condensation layer
on the lenses and so jeopardise functioning.
Reflecting surfaces near the safety light curtain light beam (above, under or lateral) can cause passive reflections that
can jeopardise functioning.
The safety device must be installed at a distance which is major or equal to the minimum safety distance S to ensure
that the operator can not reach the dangerous area until the moving dangerous object has been blocked by the ESPE.
The failure to respect the safety distance reduces or cancels ESPE the protection function. For more detailed
information about calculation of safety distance, please refer to the Instruction Manual.

ALIGNMENT PROCEDURE
The alignment between the emitting and the receiving units is necessary to
obtain the correct operation of the light curtain.
A good alignment prevents outputs instability caused by dust or vibrations.
The alignment is perfect if the optical axes of the first and the last emitting
unit's beams coincide with the optical axes of the corresponding elements of
the receiving unit.
The beam used to synchronize the two units is the closest to the connector.
Thereon we refer to such beam as SYNC and to the last one as LAST.
When SYNC beam is not engaged all other beams scan it’s not possible,
thus it’s mandatory to have SYNC beam aligned and not intercepted.
A LED user Interface provides
indications about optic alignment
together with Fieldbus connection
status.
LEDs are clearly identified through
symbols or labels allowing their
immediate reading, independently of
bars directions; Find below a short description of LEDs indications about optical
alignment. For Fieldbus connection LEDs please refer to cfr. USER INTERFACE
AND DIAGNOSTICS.
The standard installation described hereinafter is the one shown in figure with the bar assembled with the connectors
pointing down.
Two yellow LEDs (
During standard operation, the LEDs indicate the safety light curtain optical alignment status, as shown in the table.
