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.
Access protection and hazardous point protection
b
Move the supplied test object along 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 protective field
must be dimensioned such that reaching around or going around it 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.
b
If the reference contour monitoring feature is used, check the areas with the
reference contour:
°
Move the test object along the inner edge of the tolerance band of the
reference contour. The safety laser scanner must detect the test object at
each position and indicate the detection.
°
If a number of reference contours are used, check all reference contours.
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.
Additional check for mobile hazardous area protection in narrow aisles
b
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.
b
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.
