Hazardous area protection
b
Position the supplied test object at a number of points at the edges of the area to
be protected. The safety laser scanner must detect the test object at each position
and indicate the detection. How it is indicated depends on the configuration. The
number and position of sites where the thorough check is carried out must be
chosen so that undetected access to the hazardous area is impossible.
b
If a number of protective fields are used, check the edges of all protective fields.
Access protection and hazardous point protection
b
Move the supplied test object along the edges of the area to be protected. The
safety laser scanner must detect the test object at each position and indicate the
detection. How it is indicated depends on the configuration. The protective field
must be dimensioned such that reaching around or going around it is impossible.
b
If a number of protective fields are used, check the edges of all protective fields.
b
If the reference contour monitoring feature is used, check the areas with the
reference contour:
°
Move the test object along the inner edge of the tolerance band of the
reference contour. The safety laser scanner must detect the test object at
each position and indicate the detection.
°
If a number of reference contours are used, check all reference contours.
Mobile hazardous area protection
b
Place the supplied test object in the path of the vehicle and check whether the
vehicle comes to a stop in time.
b
If a number of protective fields are used, check whether the vehicle comes to a
stop in time in all of the protective fields.
b
If necessary, change the position of the test object so that a thorough check is
carried out to determine whether the protective field is active over the whole of the
required width.
b
Check the height of the scan plane. The scan plane must be at a height of at
least 200 mm so that people lying down can be reliably detected. For this purpose,
position the supplied test object at a number of points at the edges of the area
largest protective field. The safety laser scanner must detect the test object at
each position and indicate the detection. How it is indicated depends on the
configuration.
If the thorough check reveals a fault, the machine should be shut down immediately. In
this case, the mounting and electrical installation of the safety laser scanner must be
checked by appropriately qualified safety personnel.
Test of the contour detection field
If you use contour detection fields, you must test whether each contour detection field
fulfills the intended function.
Notes on planning the test
•
Which contour should be detected at which position? What is the desired result?
•
What is the desired result if the contour is not at the position?
•
What is the desired result if only one part of the contour is at the position?
•
Is it possible for there to be another object at the intended position instead of
the expected object, so that the device still recognizes the contour? What is the
desired result?
If the thorough check reveals a fault, the machine should be shut down immediately.
In this case, the mounting and electrical installation of the device must be checked by
appropriately qualified safety personnel.
Thorough visual check of the machine and the protective device
