Access protection and hazardous point protection
Move the supplied test object along the edges of the area to be protected. The
b
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.
If a number of protective fields are used (in different monitoring cases for exam‐
b
ple), check the edges of all protective fields.
If the reference contour monitoring feature is used, check the areas with the refer‐
b
ence contour:
Move the test object along the inner edge of the tolerance band of the refer‐
°
ence 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
Place the supplied test object in the path of the vehicle and check whether the
b
vehicle comes to a stop in time.
If a number of protective fields are used (in different monitoring cases for exam‐
b
ple), check whether the vehicle comes to a stop in time in all of the protective
fields.
If necessary, change the position of the test object so that a thorough check is car‐
b
ried out for each monitoring case to determine whether the protective field is
active over the whole of the required width.
Check the height of the scan plane. The scan plane must be at a height of at least
b
200 mm so that people lying down can be reliably detected. For this purpose, posi‐
tion 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 posi‐
tion 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 safety laser scanner 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 safety laser scanner must be
checked by appropriately qualified safety personnel.
Thorough visual check of the machine and the protective device
SICK recommends the following procedure:
Check whether the machine or the protective device has been modified or manipu‐
b
lated so that the effectiveness of the protective device may be impaired.
Check the following points in particular.
b
Has the machine been retrofitted?
°
Have machine parts been removed?
°
Have modifications been made to the machine's surroundings?
