•
Responds to the intrusion of the test piece.
•
Has no unmonitored areas as described in
on p. 27.
•
Complies with the Safety Distance calculated in
Minimum Safety (Separation) Distance Formula
Pay special attention at needle- and cone-shaped areas.
6. For stationary applications, verify that the marking of the perimeter of the Safey Zone on the floor corresponds with
the status of the display. If the floor has not been marked, do so now, with the aid of the display response.
7. Verify the height of the Safety Zone at the perimeter is at the expected level (for example, 150 mm for mobile
applications):
•
Safety Zones of 180 ° to 275°—Verify the height in at least four locations, approximately 90° apart from each
other.
•
Safety Zones of 90° to 180°—Verify the height in at least three locations, approximately 90° apart from each
other.
•
Safety Zones of 90° or less—Verify the height in at least two locations, approximately 90° apart from each other

8. If Zone Set switchover is used, repeat steps 1 through 7 for each Zone Set that has been configured. Ensure all fields
correspond to the expected fields as determined by the risk assessment.
If not, do not continue until the situation
is corrected.
9. If remote scanners are part of the configuration, repeat steps 1 through 8 for each Zone Set of each remote scanner
that has been configured. Ensure all fields correspond to the expected fields as determined by the risk assessment. If
not, do not continue until the situation is corrected.
10. After all corrections and changes to the configuration and the Safety and Warning Zones have been verified, proceed
to Electrical Interface to the Guarded Machine.
WARNING:
•
Trip test failure
•
Using a system that has failed a trip test can result in serious bodily injury or death. If the trip test
has failed, the system might not stop dangerous machine motion when a person or object enters
the sensing field.
•
Do not attempt to use the system if the system does not respond properly to the trip test.
Other checks to carry out include:
•
Performing system checkouts to ensure the continued reliable operation. Banner Engineering highly recommends
performing the system checkouts as described in the checkout procedures. However, a Qualified Person should
evaluate these recommendations, based on the specific application and the results of a machine risk assessment, to
determine the appropriate content and frequency of checkouts.
•
Designing the Safety Zone so that the approach towards any dangerous point of the machine can only be accessed
by passing through the Safety Zone, and the distance that a person has to cover must be longer than the minimum
safety distance.
•
Ensuring a person is unable to remain between the Safety Zone and the dangerous parts of the machine undetected.
•
Ensuring access to the dangerous areas of the machine is not possible from any unprotected area.
•
Documenting safety checks in a traceable manner.
•
Immediately shutting down the machine if the safety check session reveals hypothetical faults. The electrical and
mechanical installation must be checked for further verifications by qualified personnel.
