►
If nece
ssary, change the position of the test object so that a thorough check is
carried 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 200mm 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.
Additional check for mobile hazardous area protection in narrow aisles
►
Position the test object in front of the rack front according to DIN 15185-2. The
distance between the test object and the front of the rack must correspond to the
value specified during project planning.
►
Conduct road tests under the conditions that result in the longest stopping dis‐
tance:
°
At least 5 tests of left rack front, forward travel
°
At least 5 tests of left rack front, backward travel
°
At least 5 tests of right rack front, forward travel
°
At least 5 tests of right rack front, backward travel
✓
The industrial truck must stop in time during all travel tests.
►
Include road tests and setting values in the test certificate required by DGUV
Regulation 68.
If the thorough check reveals an error, 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 y
ou 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 an error, 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.
Checking the collision protection field
If y
ou use collision protection fields, you must perform a test to ensure that each
collision protection field fulfills its intended function.
Notes on planning the test
•
Are safety laser scanners with collision protection field correctly mounted on all
industrial trucks in both directions of travel?
•
Does the collision protection field detect the collision protection test equipment at
a distance corresponding to the maximum scanning range?
16)
•
Does the collision protection field detect test equipment for collision protection at
the intended edges of the collision protection field?
16)
•
Are reference targets correctly mounted on all industrial trucks in both directions
of travel?
16)
In t
he field editor and in the data recorder, the test equipment is marked like a reflector. This marking allows you to ensure that the test
equipment is detected, not another object.
