2. INSTALLATION MODE
2.1. Precautions to be observed for the choice and installation
Make sure that the protection level assured by the PSEN op4F/H-s
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 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 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 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.
