When devices with > 40 mm resolution are used, the height of the top beam has to be ≥ 900 mm (H2) from
machine supporting base while the height of the bottom beam has to be ≤ 300 mm (H1).
If the safety light curtain must be mounted in a horizontal position (Fig 4 - page 13) the distance between the
dangerous area and the most distant optical beam must be equal to the value calculated using the following
formula:
S = 1600 mm/s (t1 + t2) + 1200 - 0,4 H
where:
Minimum safety distance in mm.
Response time of the ESPE in seconds (cfr. TECHNICAL DATA page 43)
Machine stopping time in seconds (including the Safety Control System)
Beam height from ground; this height must always be less than 1,000 mm.
