SAFETY INFORMATION

The following points must be observed for a correct and safe use of the

 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 1.3.3 of the manual included in the CD supplied and duri ng 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 sections 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 o perating in the dangerous area must be well-trained and must have adequate kno wledge

of all the operating procedures of the safety light curtain.

 The TEST and RESET/RESTART buttons must be located outside the protected area as the operator

must check the protected area during all Test and Restart operations.

 Please carefully read the instructions for the correct functioning before powering the light curtain.

safety light curtains of the SG4-B series:

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

 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 a room complying with the technical characteristics indicated in section 10

“Technical data” of the manual included in the CD supplied.

 Do not place the device near intense and/or flashing light sources and, in particular, close to receiving unit

front surface.

controlled, according to EN 954-1 and EN 13849-1.

QUICK GUIDE

 The presence of intense electromagnetic disturbances could jeopardise device operation. This condition

has to carefully evaluated with the support of the DATASENSOR 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 t he 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 complete manual contained in the CD supplied.

ALIGNMENT PROCEDURE

The alignment between the emitting and the receiving units is necessary to obtain the corr ect functioning of
the light curtain.
A good alignment prevents output instability caused by dust or vibrations.
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.
The beam used to synchronise the two units is the first after the connector. SYNC is the optics connected
with this beam and LAST is the optics connected to the last beam after the SYNC unit.
