2. INSTALLATION MODE
2.1. Precautions to be observed for the choice and installation of the
device
Make sure that the protection level assured by the PSEN op2H-s
device (Type 2) is compatible with the real danger level of the
machine to be controlled, according to EN 954-1 and EN 13849.
• The outputs (OSSD) of the AOPD 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 AOPD must be installed in a room complying with the technical
characteristics indicated in section 10 “Technical data”.
• 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 affect
device correct operation. This condition shall be carefully assessed
by seeking the advice of Pilz 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.
