Safety Light Curtains with infrared beams

1 SG4 EXTENDED
SAFETY INFORMATION
• 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 paragraph “Minimum installation distance” of the Instruction Manual and during all
working cycle phases.
• Mounting and connection of the safety light curtain must be carried out by qualified personnel only, according
to the indications included in the Instruction Manual (refer to paragraphs “Installation”, “Mechanical Mount-
ing”, “Electrical Connections”, “Alignment Procedure”) and in the applicable standards.
• The safety light curtain must be securely placed in a particular position so that access to the dangerous zone is
not possible without the interruption of the beams (refer to paragraph “Installation” in the Instruction Man-
ual).
• 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.
•The TEST, RESET/RESTART and OVERRIDE buttons must be located outside the protected area because the
operator must check the protected area during all Test, Restart and Override operations.
NOTE
Precautions to be observed for the choice and installation
• The outputs (OSSD) of the ESPE must be used as machine stopping devices and not as command devices.
• The machine must have its own START command.
• 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 an environment complyingwith the characteristics indicated in chapter “Techni-
cal data” of the Instruction Manual.
• The ESPE must not be installed close to strong and/or flashing light sources, in particular close to the front win-
dow of receiving unit.
• The presence of intense electromagnetic disturbances could affect device’s correct operation. This condition
shall be carefully assessed with the advice of 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 condensa-
tion layer on the lenses and thus jeopardize correct operation.
• Reflecting surfaces near the safety light curtain light beam (above, under or lateral) can cause passive reflec-
tions that can jeopardize functioning.
•The safety device must be installed at a distance that is greater or equal to the minimum safety distance S to
ensure that the operator cannot reach the dangerous area until the moving dangerous object has been
blocked by the ESPE.
CAUTION
The following points must be observed for a correct and safe use of the safety light curtains of
the SG4-Extended series.
Please carefully read the instructions for the correct functioning before powering the light cur-
tain on.
CAUTION
Make sure that the protection level assured by the device is compatible with the real danger
level of the machine to be controlled, according to EN ISO 13849-1 or EN 62061.
CAUTION
The failure to respect the safety distance reduces or cancels the ESPE 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 functioning
of the light curtain. A good alignment prevents output instability caused by dust or vibrations.
After correct mechanical mounting and electrical wiring user should proceed to alignment procedure and
verify results according to next table. To enter SG4-E dedicated Alignment Mode activate RESET/RESTART/
ALIGN input during Power-On until OSSD red led blinks.
The alignment is perfect if the optical axes of the first and the last emitting unit beams coincide with the
optical axes of the corresponding elements of the receiving unit.
Both first (near the connector) and last beam are used for optical SYNC.
No Sync, check SYNC1 NONE OFF
SYNC 1 aligned NONE OFF
SYNC 2 aligned NONE OFF
One or more intermedi-
ate beams not aligned NONE OFF
All beams aligned BAD ON
All beams aligned ON
All beams aligned ON
All beams aligned EXCELLENT ON
A. Keep the receiver in a steady position and set the emitter until the yellow SYNC 1 LED is OFF. This
condition shows the effective alignment of the first synchronisation beam.
B. Rotate the emitter, pivoting on the lower optics axis, until the yellow SYNC 2 LED is OFF.
C. Delimit the area in which alignment is good andsteady through some micro adjustments - for the
first and then for the second unit - so to have the maximum alignment LEVEL ( ) and then place
both units in the center of this area.
D. Fix the two units firmly using brackets. Verify that the LEVEL on the RX unit is as high as possible and
beams are not interrupted, then verify that all LEVEL Led turns OFF if even one single beam is inter-
rupted. This verification shall be made with the special cylindrical “Test Piece” having a size suitable
to the resolution of the device used (refer to “Checks after first installation” of the Instruction Man-
ual).
E. Switch OFF and ON the device in standard operating mode. The alignment level is monitored also
during device normal operation with the same display. Once the light curtain has been aligned and
correctly fastened, the display signal is useful both to check the alignment and show a change in the
environmental conditions (occurrence of dust, light disturbance and so on) via signal level monitor-
ing.

new configuration. Particular attention has to be taken during the basic configuration manage-
ment and use.
CAUTION
Muting time-out “∞” does not comply with the requirements of IEC 61496-1. Therefore, all
possible risks must be considered and related precautions undertaken before selecting the
“∞” option.
