SICK EtherNet/IP microScan3 - Notes on the Tests

Important information
DANGER
H
azard due to lack of effectiveness of the protective device
Persons and parts of the body to be protected may not be recognized in case of
non-observance.
►
Carry out tests at least once a year.
►
Assign qualified safety personnel to carry out the tests or persons specifically
authorized for this purpose.
►
Document tests in a traceable manner.
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 76
•
Testing of the detection capability (resolution) in the context of the "Thorough
check of the area to be protected", page 77
Recommendations for further thorough checks
In man
y 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 79
•
"Test of the contour detection field", page 78
•
"Checking the collision protection field", page 78
•
Test of the relevant points on the checklist, see "Checklist for initial commissioning
and commissioning", page 215
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 79
•
"Thorough check of the principal function of the protective device", page 76
Complementary information
If a t
horough check reveals an error, 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.
4.6.3 Notes on the tests
Thorough check of the principal function of the protective device
SIC
K recommends the following procedure:
►
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 an
error.
►
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):
