b
Include road tests and setting values in the test certificate required by DGUV
Regulation 68.
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.
Checking the collision protection field
If you 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?
18)
•
Does the collision protection field detect test equipment for collision protection at
the intended edges of the collision protection field?
18)
•
Are reference targets correctly mounted on all industrial trucks in both directions
of travel?
•
Are the reference targets unobstructed so that the safety laser scanners of the
other industrial trucks have a clear view of them?
•
Are the reference targets and the scan planes of the safety laser scanners at the
same height under all foreseeable conditions?
•
Are the collision protection fields aligned with the reference targets under all
foreseeable conditions?
•
Are the reference targets intact and clean?
•
Is the safety laser scanner correctly connected to the controller of the industrial
truck?
•
Is the signal of each collision protection field correctly evaluated in the controller
of the industrial truck?
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
SICK recommends the following procedure:
18)
In the 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.
