The thorough check covers the following points:
•
Changes in the detection capability (thorough check of all configured fields)
•
Modifications, tampering and damage to the protective device or the machine,
which lead to changes in the area to be protected or the position of the protective
field
SICK recommends the following procedure:
Hazardous area protection
b
Position the supplied test object at a number of points at the edges of the area to
be protected. The safety laser scanner must detect the test object at each position
and indicate the detection. How it is indicated depends on the configuration. The
number and position of sites where the thorough check is carried out must be
chosen so that undetected access to the hazardous area is impossible.
b
If a number of protective fields are used (in different monitoring cases for exam‐
ple), check the edges of all protective fields.
Mobile hazardous area protection
b
Place the supplied test object in the path of the vehicle and check whether the
vehicle comes to a stop in time.
b
If a number of protective 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.
b
Check the height of the scan plane. The scan plane must be at a height of at
least 200 mm 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.
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:
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
Check the following points in particular.
°
Has the machine been retrofitted?
°
Have machine parts been removed?
°
Have modifications been made to the machine’s surroundings?
°
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 optics cover contaminated, scratched or destructed?
°
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.
