2 INSTALLATION
2.1 Precautionary measures when selecting and installing the
device
• Make sure that the category guaranteed by the safety light curtain
(Type 4) matches the risk assessment for the machinery that is to
be monitored, as defined in the standard EN 954-1.
• The OSSD outputs on the safety light curtain 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 safety light curtain is installed must
comply with the technical details stated for the safety light curtain
in Chapter 10, “Technical details”.
• Avoid installing the device, particularly the receiver (RX), 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 light curtain 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 light curtain.
• The activated muting function is displayed via an integral muting
lamp. Make sure that the intensity of the LED is appropriate and
that it is clearly visible, positioned close to the danger zone.
• Install and replace emitter and receiver only in pairs.
Emitter and receiver have the same serial number.
