INSTALLATION
2.1.
Precautionary measures when selecting and installing the
device
• Make sure that the category guaranteed by the safety device (Type
2 or Type 4) matches the risk assessment for the machinery that is
to be monitored, as defined in the standard EN 954-1.
•
The outputs (OSSD) on the ESPE must be used as machine stop
devices and not as command devices (the machine must have its
own START command).
•
The dimensions of the smallest object to be detected must not be
less than the resolution level of the device.
•
The environment in which the ESPE is installed must comply with
the technical details stated for the light curtain in Ch. 9.
•
Avoid installing the device, particularly the receiver, close to intense
and/or flashing light sources.
•
Avoid strong electromagnetic interference as this can adversely
affect the proper operation of the device.
•
Smoke, mist or dust within the operating environment can reduce
the range of the safety device by up to 50%.
•
Sudden temperature fluctuations beyond freezing point can cause
condensation to form on the surface of the lenses, adversely
affecting the proper operation of the safety device.
