2 INSTALLATION
2.1 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 resolution level of the device.
The ESPE must be installed in an environment complying with the characteristics indicated in
TECHNICAL
DATA page 36
The ESPE must not be installed close to strong and/or flashing light sources, in particular close to the front
window of receiving unit.
The presence of intense electromagnetic dis
turbances could affect device’s correct 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.
Kind of mechanical fixation is suitable for vertical light curtain installation only.
In such a case vibrations and bump limits on z-axis remains compliant according declared regulations (see
cfr.
TECHNICAL DATA page 36
Fig 6 - Vertical installation of the light curtain
Keep mechanical environment as free as possible from all stress any case: if that is not possible, minimize the
impact of mechanical stress on X and Y axes, i.e. re-aligning the light curtains in parallel to Z-axis.
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.
