Status Indicators for Cascaded Applications
When multiple light screens are cascaded, some
unique indications may occur, as indicated in
Figure 4-7 and in the table at right.
When a receiver’s CSSI input is in a Stop
condition (because of a blocked light screen
further upstream in the cascade, or because of a
Stop signal from an E-stop button, for example),
the display on the downstream receivers, including
the master receiver, will be bracketed by a pair
of vertical “goalposts.” See Section 5.1.1 for an
illustration.
