5.6.2.3
With the exception of the regulatory signs, each controller output monitored requires a
connection to the green lamp drive voltage for that output. For single aspect outputs,
the drives to those aspects are used in place of the green signal.
Connection to the unit is via cableform 667/1/26586/000 and each state connection
must be terminated, as indicated in Figure 20, and as detailed in the Instation Computer
Printout.
