210E / 210ECL / 2010 / 2010ECL / 2018ECL SERIES SIGNAL MONITOR
OPERATIONS MANUAL

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 number of load switches
provided and the capabilities of the Controller Unit. A Flashing Yellow Arrow approach is
actually monitored using two physical channels of the Signal Monitor. In the basic FYA
mode of the unit, one additional load switch is required for each FYA approach to be
monitored. Thus a cabinet providing four vehicle phases, four pedestrian phases, and four
FYA approaches would require sixteen load switches. The compact FYAc mode requires
the Controller Unit to remap the Yellow outputs of the pedestrian load switches to drive the
protected Green Arrow signals of the FYA approaches. In this mode the cabinet can
provide the four FYA approaches with the existing twelve position output assembly. See
Section 4.4.8 for FYA Mode programming.
2.20.1 FYA MODE
In the FYA mode (see Table 2-1), the cabinet must be wired such that for each FYA
approach, the solid Green protected Arrow is driven by a load switch monitored on
channels 1, 3, 5, and 7. The associated solid Red Arrow, solid Yellow Arrow, and flashing
