2. INSTALLATION MODE
2.1. Precautions to be observed for the choice and installation
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 954-1 and EN 13849-1.
 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”.
 Do not install device near strong and/or flashing light sources or
close to similar devices.
 The presence of intense electromagnetic disturbances could
jeopardise device functioning. This condition shall be carefully
assessed by seeking the advice of 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.
