o test the light curtain, use the appropriate ST I-
supplied test object, or properly sized opaque cylindrical
object.
If you are using the Channel Select or Floating
B lanking features and the object to be ignored does not
completely prevent access to the hazardous area, either
(1) use a mechanical guard or other means to block
access or (2) increase the minimum safe distance and
use a larger test object diameter as explained in the
In
stallation and Operating Manual.
1. Disable the machine. Power on the light curtain.
2. Inspect the machine to ensure entry to the
hazardous area is only through the light curtain sensing
field. If not, additional guarding, including mechanical
barriers may be required.
3. Verify that the mounting distance of the light
curtain is equal to or greater than the minimum safe
distance from the hazardous point. E nsure the operator
is not able to stand un
detected between the light curtain
and the hazard.
4. Check for external damage to the light curtain,
the machine, electrical cables and wiring.
5. Interrupt the sensing field with the
test
object t
o check the effectiveness of the light curtain.

watch for any unprotected access to the point of hazard.
6. Start the machine. Interrupt the sensing field
wi th the test object. T he machine should stop
immediately. Never insert the tes

dangerous parts of the machine! With the machine at
rest, interrupt the sensing field with the test object.
that the machine will not start with the test object in the
sensing field.
7. E nsure the braking and machine stop systems
are working properly in accordance with the machine
manufacturerÕs requirements. If the machine does not
stop fast enough, adjust the braking system or increase
the distance from the light curtain to the
point hazard.
8. If the safety devices or machine fail any of these
tests, do not run the machine. Immediately lockout the
machine to prevent its use and notify the supervisor
9. If the Channel Select is reprogrammed or
disabled, you must repeat these test procedures.
10. Close and lock the light curtai n contr
enclosure door, if applicable.
