CHAPTER 2
INSTALLATION
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" on page 83.
• 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 controlled,
according to EN ISO 13849-1: 2015 or EN 62061:2005/A2: 2015.
