SICK microScan3 Core I/O

Minimum requirements
T
he following thorough checks must be carried out at least once a year:
•
"Thorough check of the principal function of the protective device", page 62
•
Thorough check of the detection capability (resolution) in the context of the "Thor‐
ough check of the area to be protected", page 63
Recommendations for further thorough checks
In many cases, depending on the application conditions, the risk assessment of the
machine determines that further thorough checks are required or that some thorough
checks must take place more frequently.
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 64
•
"Test of the contour detection field", page 63
•
Test of the relevant points on the checklist, see "Checklist for initial commissioning
and commissioning", page 159
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 64
•
"Thorough check of the principal function of the protective device", page 62
Complementary information
If a t
horough 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.
5.5.3 Notes on the tests
Thorough check of the principal function of the protective device
SIC
K 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, haz‐
ardous 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
•
A
ctivate 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.
