2.20.2.1 FYAC MONITORING FUNCTIONS
If a FYA channel pair is enabled for FYAc operation, the Signal Monitor will monitor the
FYAc logical channel pair for the following fault conditions:
2.20.2.1.1 CONFLICT
Channel conflicts are detected based on the Permissive programming jumpers on the
Program Card for each channel. This operation remains unchanged from normal operation
except for the solid Yellow arrow (FYA clearance) signal.
2.20.2.1.1.1 PROTECTED YELLOW CHANGE INTERVAL CONFLICT
The Signal Monitor will verify during the Yellow change interval of the Protected Turn
channel (Green arrow; channels 9,10,11,12) that no conflicting channels to the solid Yellow
arrow channel (clearance) are active. The conflicting channels are determined by the
Program Card compatibility programming of the Protected Turn channel (Green arrow;
channels 9,10,11,12) of the pair.
2.20.2.1.1.2 PERMISSIVE YELLOW CHANGE INTERVAL CONFLICT
During all other times the Signal Monitor will verify that no conflicting channels to the solid
Yellow arrow channel (clearance) are active as determined by the Program Card
compatibility programming of the Permissive Turn channel (flashing Yellow arrow;
Channels 1,3,5,7).
2.20.2.1.2 FLASH RATE DETECTION
When the FLASHRATE FAULT option is not disabled (see Section 4.5.7), the Signal
Monitor will monitor a flashing yellow arrow output for a lack of flashing operation. If any of
the enabled flashing yellow arrow signals on channels 1,3,5,7 remain active for more than
the FYA Flash Rate Fault time (Section 8.2), the Signal Monitor will enter the fault mode,
transfer the OUTPUT relay contacts to the Fault position, and display status. The Signal
Monitor will remain in the fault mode until the unit is reset by the RESET button or the
EXTERNAL RESET input.
2.20.2.1.3 RED FAIL
A Red Fail fault will occur if the solid Red Arrow AND solid Yellow Arrow AND flashing
Yellow Arrow AND solid Green Arrow all remain inactive for the Red Fail fault response
time. The fault channel status will be indicated for both channels of the pair. The Red and
Yellow inputs (typically unused) for channels 9, 10, 11, and 12 do not affect the Red Fail
condition for the FYA channels 1, 3, 5, and 7.
