The two previous faults may be also be displayed individually. This status is not reset by an
AC Line power interruption. To enter this display mode remove the Program Card. The
sequence is as follows:
Reset Event PCA LED
Fault Status LEDs
Channel Status LEDs
---
#1
Single flash
Current Fault Status (newest) Current RYG channel status
#1
#2
Double flash Event #2 Fault Status
Event #2 RYG channel status
#2
#3
Triple flash
Event #3 Fault Status (oldest) Event #3 RYG channel status
...
(repeats back to top)
To enter this display mode remove the Program Card. The channel status display will
alternate between the channels which were involved in the fault (fault status) for 2 seconds,
and the field signals active at the time of the fault for 6 seconds. The channels involved in
the fault will flash their Green, Yellow, and Red indicators simultaneously at a 4 Hz rate for
the 2 second interval. The PCA LED will pulse once per second to indicate the current fault
(#1, newest).
Depressing the Reset button advances the display mode from the current fault ( #1) to the
fault display mode for fault #2. The PCA LED will pulse twice per second to indicate the
previous fault (#2).
Depressing the Reset button again advances the display mode from fault #2 to the fault
display mode for fault #3. The PCA LED will pulse three times per second to indicate the
previous fault (#3).
Depressing the Reset button again returns the display mode from fault #3 to the fault display
mode for fault #1.
To exit this display mode, replace the Program Card. If the Program Card is removed while
the model 210ECL unit has
not
been triggered by a fault, the fault status display mode will
show the Green, Yellow, and Red channels active when the Program Card was removed. If
a PCA fault is displayed during the review, the PCA LED will not flash during the Fault Status
display step to indicate the fault number.
2.20 FLASHING YELLOW ARROW (FYA) OVERVIEW
This unit is designed to monitor an intersection with up to four approaches using the four
section FYA movement outlined by the NCHRP Research Project 3-54 and NEMA TS-2
Amendment #4-2012 on Protected/Permissive signal displays with Flashing Yellow Arrows.
For
monitoring purposes an FYA approach is defined as a four input “logical channel”
consisting of the solid Red Arrow, solid Yellow Arrow, flashing Yellow Arrow (permissive),
and solid Green Arrow (protected). The Signal Monitor combines two physical channels to
monitor each “logical” FYA approach.
Two cabinet configurations are supported depending on the assignment of load switches to
channels. A Flashing Yellow Arrow approach is actually monitored using two physical
channels of the Signal Monitor. In the NYCDOT 2010ECL-NYC, the Ped Yellow load switch
outputs of channels 9-12 are remapped to channels 13-16 Green (when enabled) to monitor
the protected Green arrow signals. The CU must be programmed to drive the Channel 9-12
Yellow load switch inputs with the protected Green phase output.
In the basic FYA mode of the unit, the FYA Overlap (Ra, Ya, fYa) channels are assigned to
channels 1-4. The FYA channel pairing becomes 1-13, 2-14, 3-15, and 4-16.
In the compact FYAC mode assigns the FYA Overlap (Ra, Ya, fYa) channels to channels 1,
3, 5, and 7. The FYA channel pairing becomes 1-13, 3-14, 5-15, and 7-16. This optional
mode provides a more conventional phase to channel assignment using odd phases for the
FYA Overlaps.
