FYA ENABLE
– When this feature is enabled the monitor disables the Co-Channel feature and uses the channel mapping
table for Flashing Yellow Arrow channel programming instead. The factory default for this feature is
NO
.
FYA IGNORE YEL CONFLICT
– When this feature is enabled the monitor will ignore a Yellow to Yellow conflict
between the channel with the protected left turn displays and the opposing through channel when terminating a Flashing
Yellow Arrow. Most FYA implementations will need to use this feature. The factory default for this feature is
NO
.
FYA DRIVER IS YEL
– When this feature is enabled the monitor will use the Yellow input of the FYA channel as the input
driving the FYA display. When this feature is disabled the monitor will use the Green input as the driver for the FYA
display. The factory default for this feature is
NO
(Green input).
CHANNEL 1-16 FLASHING YELLOW ARROW MAPPINGS
– The number on the left indicates the channel that the
channel mappings to the right will apply to. The only channels that should have mappings are the ones that are protected left
turn displays. There should be two mappings for each channel that is the protect display of an FYA head. The first is the
permissive channel. This is the channel that the Flashing Yellow Arrow is connected to. The other is the opposing
conflicting channel that is active while in the permissive portion of the left turn movement. The program card should be
programmed with the FYA channel as permissive with the protected left turn channel. When correct, one mapping will show
an
R
indicating the conflicting channel and the other will show a
Y
or
G
indicating which input for that channel will be
monitored as the FYA display.
The per channel mappings will be active only if the FYA Enable setting is set to
YES
. The factory default for the channel
settings of this feature is all channels unmapped.
4.6.2.1.7.6
Co-Channel Child Settings
The Co-Channel Childs feature allows the user to modify the Red Fail test for each channel to include the Green, Yellow,
and/or Walk displays from other channels. This allows for Red Fail monitoring of heads with more than 3 sections. This
feature is mutually exclusive with FYA Enable. If FYA Enable is set to
YES
, you will not be able to access this screen. You
will need to go the FYA Left Turns display and set the FYA Enable to
NO
to view this display. See Section
2.6.2
for more
detailed information on Co-Channel Monitoring.
Use the left (◄) or right (►) pushbutton to select the field to change. Use the up (▲) or down (▼) pushbutton to scroll the
viewing window to the other channels. Use the
ENTER
pushbutton to toggle the setting. Press the
ESCAPE
pushbutton to
exit.
CO-CHAN / PER CHAN RED EN
– When this feature is enabled the monitor will modify how a Red Fail test is
performed. For each parent channel (row) the Green (and the Walk if in Type 12 mode) and optionally the Yellow of
additional channels (childs) may be included in the Red Fail test for that channel. The factory default for this feature is
NO
.
Enabling this feature also enables the Per Channel Red Enable feature. The Per Channel Red Enable feature allows the user
to only perform Red Fail and Field Check monitoring for channels that have been enabled for this feature when the Red
Enable input is active.
CO-CHAN INCLUDES YEL
– When this feature is enabled the monitor will include the yellow of the child channels as
well as the green (and the Walk if in Type 12 mode). The factory default for this feature is
NO
.
CHANNEL 1-16 CO-CHANNEL CHILDS SETTINGS
– The numbers at the left side of the screen correspond to parent
channels. The small numbers across the top of the screen correspond to child channels. Enabled is indicated by a
Y
and
disabled is indicated by a dash
(
−
). The per channel settings will be active only if the Co-Chan / Per Chan Red En setting is
set to
YES
. The factory default for the channel settings of this feature is all channels have no childs enabled.

Threshold Settings
Use the up (▲) or down (▼) pushbutton to navigate between the settings. Use the
ENTER
pushbutton to toggle the setting.
Press the
ESCAPE
pushbutton to exit.
LED THRESHOLDS
– When this feature is enabled the monitor will use more restrictive AC voltage thresholds for
determining the ON and OFF state of field indications. See Section
2.6.4
for more information. The factory default for this
feature is
NO
.
24V-2 TO 12VDC
– When this feature is enabled the +24V Monitor II input thresholds will be modified to m12
VDC. The new voltage threshold will be 11.5 VDC and above, sensed as valid; 10.75 VDC and below, sensed as invalid.
Voltages between these thresholds may be sensed as valid or invalid. See Section
2.6.7
for more information. The factory
default for this feature is
NO
.
