Test Procedure Log C-1
Appendix C. Test Procedure Log
The following test procedure must be performed by qualified personnel during initial Shadow
8 installation, according to the employer’s regular inspection program, and after any
maintenance, adjustment or modification to the Shadow 8 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 Shadow 8, use a test object of the correct size.

Item Condition Comments
1. Disable the guarded machine. Apply power to the Shadow 8.
❑
Pass
❑
Fail
2. Visually inspect the machine to ensure that access to the pinch
point is only through the Shadow 8 sensing field. 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 Shadow 8 is equal to
or greater than the calculated minimum safety distance from the
pinch point. See Calculating the Safety Distance, page 2-2.
Ensure that the operator is not able to stand between the
Shadow 8 sensing field and the pinch point.
❑
Pass
❑
Fail
4. Check for signs of external damage to the Shadow 8, 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 Shadow 8 sensing field with the proper size test
object. Move the test object inside the perimeter (along the top,
sides and bottom) of the sensing field and up and down through
the center. At least one Individual Beam Indicator must be lit
while the test object is anywhere in the sensing field. If in
Automatic Start mode, verify that the Machine Run/Stop LED is
illuminated red. If in Start/Restart Interlock mode, verify that the
the Machine Run/Stop LED is illuminated red and the yellow
Interlock/Alarm LED is lit. Turn the Program/Run/Start key switch
to START before proceeding to step 6.
❑
Pass
❑
Fail
6. Start the machine. While the machine is in motion, interrupt the
sensing field 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 sensing
field with the test object. Verify that the machine will not start with
the test object in the sensing field.
❑
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 sensing field to the pinch 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.
