2.20.1 FYA MODE
In the FYA mode (see Table 2-1), the CU must be configured such that for each FYA
approach, the solid Green protected Arrow is driven by a Ped load switch input on channels
9, 10, 11, and 12. The NYCDOT 2010ECL-NYC will remap these Ped Yellow inputs to be
monitored by channels 13, 14, 15, and 16 respectively. Inputs to channel 9-12 Yellow will be
forced to 0 Vac.
The associated solid Red Arrow, solid Yellow Arrow, and flashing Yellow Arrow (Overlap
phase) must be driven by a load switch monitored on channels 1, 2, 3, and 4 respectively.
The Signal Monitor associates channel 1 with 13, channel 2 with 14, channel 3 with 15, and
channel 4 with 16, when FYA monitoring is enabled for that respective approach. See Section
4.4.8 for FYA Mode programming.

2.20.1.1 FYA MONITORING FUNCTIONS
If a FYA channel pair is enabled for FYA operation, the Signal Monitor will monitor the FYA
logical channel pair for the following fault conditions:
2.20.1.1.1 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.
2.20.1.1.1.1 PROTECTED YELLOW CHANGE INTERVAL CONFLICT
The Signal Monitor will verify during the Yellow change interval of the Protected Turn channel
(Green arrow; channels 13-16) that no conflicting channels to the solid Yellow arrow channel
(1,2,3,4) are active. The conflicting channels are determined by the Program Card
compatibility programming of the Protected Turn channel (Green arrow; channels 13-16) of
the pair.
2.20.1.1.1.2 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, 2, 3, and 4).
2.20.1.1.2 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 (1,2,3,4) for a lack of flashing operation. If any of
