SAFERY LASER SCANNER
VERTICAL APPLICATION CONFIGURATION
Figure 3 - Vertical application
The device uses a vertical protective field (the red area in the figure) to detect someone
passing through it.
In this example the only way to reach the hazardous point is to pass through an open-
ing: all other access points to the machine ar
e protected by some physical barrier or
other sensors.
The safety laser scanner employs a safe vertical protective field (the red area in the fig-
ure) to detect any passage through this access
point (with a given detection capability,
i.e. 40 mm, needed to detect an arm).
If the device detects someone crossing the safety zone, the OSSD pair goes to the OFF-
s
tate to stop the machine movement that is causing the hazard.
When a person has completely passed through the monitored area, after a stop caused
by
safety function, the machine must remain stopped until a manual restart signal is
given. This signal must be given only after checking that nobody remains in or close to
the hazardous point.
NOTE
When the approach direction is > 30° or < -30° relative to the detection
plane itself, the safety laser scanner shall have a facility for reference
boundary monitoring, according to IEC 61496-3.
