hat 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.
Visual check of the machine and the protective device
R
ecommended approach:
b
Check whether the machine or the protective device has been modified or manipu‐
lated so that the effectiveness of the protective device may be impaired.
b
In particular, check the following points:
°
Has the machine been retrofitted?
°
Have machine parts been removed?
°
Have modifications been made to the surroundings of the machine?
°
Are there any defective cables or open cable ends?
°
Have the protective device or its parts been dismantled?
°
Is the protective device damaged?
°
Is the protective device severely contaminated?
°
Is the optical cover contaminated, scratched or destroyed?
°
Has the protective device’s alignment been changed?
°
Are there any objects (e.g. cables, reflective surfaces) in the protective field?
If one of the points applies, the machine should be shut down immediately. In this case,
the machine and the protective device must be checked by appropriately qualified
safety personnel.
