In many cases, it makes sense to carry out the following thorough checks together
with the regular thorough check:
•
"Thorough visual check of the machine and the protective device", page 54
•
"Test of the contour detection field", page 54
•
Test of the relevant points on the checklist,
see "Checklist for initial commissioning
In many cases, it makes sense to carry out the following thorough checks daily:
•
"Thorough visual check of the machine and the protective device", page 54
•
"Thorough check of the principal function of the protective device", page 53
Complementary information
If a 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.

Notes on the tests
Thorough check of the principal function of the protective device
SICK recommends the following procedure:
b
Watch the display and the status LEDs above the safety laser scanner’s display.
If, when the machine is switched on, at least one LED above the safety laser
scanner’s display does not light up permanently, you must assume that there is a
fault.
b
Test the function of the protective device by triggering the protective function once
and observing the safety output’s reaction using the reaction of the machine, for
example.
°
All applications: during the thorough check, observe whether the safety
laser scanner displays the interruption of the protective field using the LEDs
and/or the display.
°
Stationary application (hazardous area protection, access protection, hazard‐
ous point protection):
•
Interrupt the protective field using the supplied test object and observe
whether the machine stops.
°
Mobile application (mobile hazardous area protection):
•
Place the supplied test object in the path of the vehicle and observe
whether the vehicle stops.
OR
•
Activate a protective field, which is interrupted by at least one test object
and check the expected reaction (for example by an automatic thorough
check in the safety controller).
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 check of the area to be protected
The area to be protected and the detection capability are examined during this thor‐
ough check.
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:
