Minimum Distance To Obstacles - Honeywell SYA14 Series Manual

3.5.1 Minimum distance to obstacles

Minimum distance to
obstacle
Safety extension
When the zones limit follow physical obstacle (for example along a wall), the distance between the obstacle and the
zone limit, measured on the segment from the scanning head, must not be closer than 250 mm (9.85 in.). The 250 mm
distance to obstacles is a maximum value taking into account the influence of all environment parameters. For a
given sensor, at constant
temperature, a distance to obstacle of 120 mm can reliabily be used
IMPROPER PROTECTION DUE TO MINIMUM DISTANCE TO OBJECT
If the minimum distance to the object allows undetected access to machine, use additional safety sensors or
hard guarding to force personnel to go through the detection area.
Failure to comply with these instructions could result in death or serious injury.
