System Operation
Status Indicators for Cascaded Applications
When multiple light screens are cascaded, some unique
indications may occur, as indicated in Figure 4-7 and table 4-2.
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.
