5.5.4.2 Turn Signal Dependant Operation
Example
Figure 5-14 shows an example of an intersection
with eight phases numbered 1 through 8.
Table 5-4. Turn Signal Dependant Operation Output Connection/Programming Example
Connect Phase Selector Output
Output 1 (Rear output 1 gray/white)
Output 2 (Rear output 2 blue/white)
Output 3 (Rear output 3 violet/white)
Output 4 (Rear output 4 brown/white)
Output 5 (AIP output 1)
Output 6 (AIP output 2)
Logic Common (gray/black)
AIP Opto Common
Table 5-4 lists the phase selector outputs to
connect to the controller preempt inputs. The
table also lists which phases to display.
For example, a northbound priority vehicle
signaling for a left turn activates Output 5, which
displays green for phases 1 and 6. All other
phases are red.
