b
If a number of pr
otective fields are used (in different monitoring cases for exam‐
ple), 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 for each monitoring case to determine whether the protective field is
active over the whole of the required width.
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.
Test of the contour detection field
T
he area to be protected and the detection capability are examined during this thor‐
ough check.
Recommended procedure:
b
Position the supplied test object at a number of points at the edges of the area to
be protected. The safety camera sensor must detect the test object at each posi‐
tion and indicate the detection. How it is indicated depends on the configuration.
b
If several contour detection fields are used (for different monitoring cases, for
example), check the edges of all contour detection fields.
b
Using the test object provided, check whether the configured tolerance band has
the required size and the dangerous state is ended in time.
b
When used for fall protection: Slowly move the vehicle towards the floor opening
(e.g., stair landing) and check whether the configured tolerance band has the
required size and the dangerous state is ended in time.
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.
ROI test
T
his test is used to test the safe distance check.
Recommended procedure:
b
Move the object for which the ROI has been configured into the field of view and,
if necessary, remove it from the field of view. The camera system must determine
the distances correctly and switch the configured safety outputs according to the
ROI tolerance band setting.
b
Using an object (e.g. a cardboard box of sufficient size) between the contour and
camera system, check whether the camera system switches the configured safety
outputs according to the ROI tolerance band setting.
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.
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 flying leads?
°
Have the protective device or its parts been dismantled?
°
Is the protective device damaged?
