PRECAUTIONS TO BE OBSERVED FOR THE CHOICE AND
INSTALLATION
• Use only matched emitter and receiver pairs with same serial no.
• 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 reso-
lution level of the device.
• The ESPE must be installed in an environment complying with the characteristics
indicated in
Technical Data, starting on page 55.
• The ESPE must not be installed close to strong and/or flashing light sources, in par-
ticular close to the front window of receiving unit.
• The presence of intense electromagnetic disturbances could affect device’s cor-
rect operation.
• This condition shall be carefully assessed with the advice of DATALOGIC 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 thus jeopardize correct
operation.
CAUTION: Make sure that the protection level assured by the light curtain
device is compatible with the real danger level of the machine to be con-
trolled, according to EN ISO 13849-1: 2015 or EN 62061:2005/A2: 2015.
