B-1 Test Procedure Log
The following test procedure must be performed by qualified personnel during initial F3SL system installation,
according to the employer’s regular inspection program and after any maintenance, adjustment or modification
to the F3SL system or the guarded machine. Testing ensures that the light curtain, safety system, and machine
control system work together to properly stop the machine. Failure to test properly could result in serious injury
to personnel. To test the F3SL system, use the correct size test object.

1. Disable the guarded machine. Apply power to the F3SL system.
Pass
Fail
2. Visually inspect the machine to ensure that access to the danger point is
only through the F3SL detection zone. If not, additional guarding, including
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 F3SL system is equal to or
greater than the calculated minimum safety distance from the danger
point. See Section 8—Safe Mounting Distance for further information.
Ensure that the operator is not able to stand between the F3SL detection
zone and the danger point.
Pass
Fail
4. Check for signs of external damage to the F3SL system, the machine
and the electrical cables and wiring. If damage is found, lock the machine
off and report to the supervisor.
Pass
Fail
5. Interrupt the F3SL system detection zone with the proper size test
object. Move the test object inside the perimeter (along the top, sides and
bottom) of the detection zone and up and down through the center. At least
one Individual Beam Indicator must be lit while the test object is anywhere
in the detection zone. If in automatic start mode, verify that the red
machine start light is lit. If in start/restart interlock mode, verify that the red
machine stop and yellow interlock lights are on. Press and release start
button before proceeding to step 6.
Pass
Fail
6. Start the machine. While the machine is in motion, interrupt the detec-
tion zone with the 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 detection zone with the test object. Verify that
the machine will not start with the test object in the detection zone.
Pass
Fail
7. Verify that the braking system is working properly. If the machine does
not stop fast enough, adjust the braking system or increase the distance
from the detection zone to the danger point.
Pass
Fail
8. If the safety devices or the machine fails any of these tests, do not run
the machine. Immediately tag or lockout the machine to prevent its use
and notify the supervisor.
Pass
Fail
