T o test the light curtain, use the appropriate ST I -
supplied test object, or properly sized opaque cylindrical
object.
I f you are using the C hannel S elect or F loating
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
I nstallation and Operating Manual.
1. Disable the machine. Power on the light curtain.
2. I nspect the machine to ensure entry to the
hazardous area is only through the light curtain sensing
field. I f 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 undetected between the light curtain
and the hazard.
4. C heck for external damage to the light curtain,
the machine, electrical cables and wiring.
5. I nterrupt the sensing field with the test
object to check the effectiveness of the light curtain.

manufacturerÕs requirements. I f the machine does not
stop fast enough, adjust the braking system or increase
the distance from the light curtain to the point hazard.
8. I f the safety devices or machine fail any of these
