2.16.5 FYA YELLOW TRAP CONFLICT DETECTION
When the FYA TRAP DETECT option is enabled, the CMU-212 will monitor each FYA
permissive turn channel for the FYA Yellow Trap condition. The FYA Yellow Trap conflict
condition occurs when the Permissive Turn channel (flashing yellow arrow) sequences to
the solid yellow arrow clearance while the Opposing Through channel is still showing a
green ball.
When the FYA Yellow Trap Conflict condition is detected, the CMU-212 will enter the fault
mode, transfer the OUTPUT relay contacts to the Fault position, and display the
“CONFtrap” fault status screen. The CMU-212 will remain in the fault mode until the unit is
reset by the RESET button.
