OPERATION
If the protected area is clear, the two outputs on the Receiver are active and enable the
machine to which they are connected to operate normally.
Each time that an object bigger than or equal in size to the resolution of the system intercepts
the optical path of one or more beams, the Receiver deactivates the outputs.
This condition enables hazardous machine movements to be stopped (by means of an
adequate machine emergency stop circuit).
The resolution is the minimum dimensions that an object must have so that, on crossing
the protected area, it will certainly intercept at least one of the optical beams generated by
the light curtain (Figure 1).
Figure 1
The resolution is constant irrespectively of work conditions, as it only depends on the geometric
characteristics of the lenses and the distance between the centres of two adjacent lenses.
The
height of the protected area
is the height that is actually protected by the safety light
curtain. If the latter is placed horizontally, this value refers to the depth of the protected area.
The
working range
is the maximum operative distance that can exist between the Emitter and
the Receiver.
VISION MXL is available with the following resolutions:
–
30 mm (protected height from 150 mm to 1200 mm)
PROTECTION OF HANDS
–
40 mm (protected height from 300 mm to 1200 mm)
PROTECTION OF HANDS
VISION MXL is available also in the
2, 3, 4 beams
configuration with the following lens pitch:
–
500mm (2 beams), 400mm (3 beams), 300mm (4 beams).
