A-1 Tests To Perform
The following tests must be performed at installation and after any maintenance, adjustment, repair or modifica-
tion to the F3SS or the machine. Testing ensures that the F3SS and the machine control system work properly
to stop the machine. Failure to test properly could result in serious injury to personnel.
The following Test Procedure must always be performed by qualified personnel after the mounting, alignment
and wiring steps are completed and before the F3SS is used to control the machine. To test the F3SS, use an
opaque object of the appropriate size.

1.Disable the machine to be guarded. Turn power on to the F3SS.
Pass
Fail
2.Visually inspect the machine to ensure that entry to the hazardous area
is only through the F3SS sensing beam. If not, additional guarding includ-
ing mechanical barriers may be required. Verify that all additional guarding
devices and barriers are installed and operating properly.
Pass
Fail
3.Verify that the mounting distance of the F3SS is equal to or greater than
the calculated maximum safe distance from the point of hazardous opera-
tion.
Pass
Fail
4.Check for signs of external damage to the F3SS, the machine and the
electrical cables and wiring. If any damage is found, lockout the machine
and report to the supervisor.
Pass
Fail
5.Next, interrupt the sensing beam with a proper size test object to check
the effectiveness of the F3SS. Verify that the red indicator is on and the
green indicator is off while the test object is anywhere in the sensing beam.
Also, watch for any unprotected access to the danger point.
Pass
Fail
6.Start the machine. While the machine is in motion, interrupt the sensing
beam with a test object. The machine should stop immediately. Never
insert the test object into the dangerous parts of the machine. With the
machine at rest, interrupt the sensing field with the test object. Verify that
the machine will not start with the test object in the sensing beam.
Pass
Fail
7.Make sure that the braking systems working properly. If the machine
does not stop fast enough, adjust the braking system or increase the dis-
tance from the sensing beam to the point of operation hazard.
Pass
Fail
8.If the safety devices or the machine fails any of these test, do not run the
machine. Immediately tag or lockout the machine to prevent its use and
notify the supervisor.
Pass
Fail
WARNING
The F3SS should be tested by breaking the beam at least once per shift or every 24hours at minimum.
