Installing Blanking Windows
Blanking windows are easy to install. If you are blanking more than one beam, you attach the
master blanking window first and connect "slave" blanking windows above
it. This increases
the blanked area. The maximum number of beams that can be blanked is 5.
Because blanking windows attach to the receiver, they are clearly visible to personnel. As a
result, it is obvious when a beam is blanked.

DANGER
!
INCORRECT SAFETY DISTANCE WHEN USING BLANKING WINDOWS
• Ensure that the correct safety distance exists between the light curtain and the hazardous
area. See Chapter 2 for detailed information on object sensitivity, depth penetration factor
and calculating the safety distance.
• When more than one beam is blanked, but the blanked area is not completely obstructed,
the depth protection factor is at least 36” (914.4 mm).
• Maintain access to blanking master and slave windows under supervisory control to avoid
unauthorized usage.
Failure to comply with these instructions will result in death or serious injury.
DANGER
!
UNPROTECTED ZONE DUE TO EXTRA BLANKING WINDOWS
• DO NOT blank more than two beams of the light curtain unless a conveyor or other object
completely fills the blanked area, or if you use barrier guards to block any unfilled areas.
• Remove blanking windows when they are no longer needed.
• Maintain access to blanking master or slave windows under supervisory control to avoid
unauthorized usage.
Failure to comply with these instructions will result in death or serious injury.
NOTICE
Install the master blanking window at the lowest blanked beam. Install slaves above the
master.
Here are steps to install the master blanking window. If you are blanking more than one
beam, you attach the master blanking window first and connect slave blanking windows
above
it (installing slaves is discussed in the next section).
1. Locate the master blanking window. Notice a cable is attached at one end. The other
end of the cable has a connector that screws into the mating connector at the top of the
receiver. See the illustration in Figure 3-1 to locate each component.
2. The master blanking window attaches to the receiver by sliding it down from the top (it
can also be slid up from the bottom). Determine which light beam to blank. If you
