MINIMUM FLASH
– The Minimum Flash time displayed is the time setting that is jumpered on the program card.
According to the NEMA specification, the monitor will add one second to the jumpered time to get the actual Minimum
Flash time used and that the jumpered value cannot be less than five seconds. If the jumpered value is less than five seconds,
it will be displayed as five seconds as this will be the value used.

Dual Indication / Field Check
Use the arrow pushbuttons to navigate between the settings. Use the
ENTER
pushbutton to toggle a setting. Press the
ESCAPE
pushbutton to exit.
CHANNEL 1-16 DUAL INDICATION / FIELD CHECK
– When this feature is enabled for a channel, the channel will be
checked for more than one field indication being sensed as ON and the monitor will check the field status of each indication
against the controller commanded state for each indication. Dual Indication and Field Check testing for each channel are
turned on or off together. Enabled is indicated by a
Y
and disabled is indicated by a dash
(
−
). Typically all vehicle channels
are enabled although special consideration should be given to channels that are part of a vehicle display with more than three
sections. Pedestrian channels can be enabled, but care must be taken to insure that the monitoring of the yellow portion of
the channel matches what the controller thinks it should be. If not considered, field check faults may occur. The factory
default for the Dual Indication / Field Check settings are all channels enabled. See Section
2.5.3
for more detailed
information on Dual Indication testing. See Section
2.5.7
for more detailed information on Field Check testing.
GRN-YEL MON ENABLED
– When this feature is enabled the monitor will check for simultaneously active Green and
Yellow field signal inputs on the same channel. This feature is active on all channels when selected and is not active if the
Red Enable input is not active. The factory default for Green-Yellow Dual Indication monitoring is off. See Section
2.5.4
for more detailed information on Dual Indication testing.
The Green - Yellow Enable feature can be used in conjunction with the Field Check / Dual Enables feature. Channels which
have their Field Check / Dual Enable settings enabled will perform full Dual Indication monitoring. Channels, which have
their Field Check / Dual Enable settings disabled, will perform the Green-Yellow Dual Indication monitoring only.
4.6.2.1.7.3
Per Channel Red Enables
Use the arrow pushbuttons to navigate between the settings. Use the
ENTER
pushbutton to toggle the setting. Press the
ESCAPE
pushbutton to exit. See Section
2.6.5
for more detailed information on Per Channel Red Enables.
PER CHAN RED EN / CO-CHAN
– When this feature is enabled the monitor will only perform Red Fail and Field Check
monitoring for channels that have been enabled for this feature when the Red Enable input is active. Only the Red Fail and
Field Check monitoring are affected by this feature. Other monitoring normally controlled by the Red Enable input (Short
Yellow, Short Clearance, and Dual Indication) still operate as defined and are not affected in any way by the activation of this
feature. The factory default for this feature is no.
Enabling this feature also enables the Co-Channel feature. The Co-Channel 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.
CHANNEL 1-16 RED ENABLES
– Enabled is indicated by a
Y
and disabled is indicated by a dash
(
−
). The per channel
settings will be active only if the Per Chan Red En / Co-Chan setting is set to
YES
. The factory default for the channel
settings of this feature is all channels enabled.
4.6.2.1.7.4
Flashing Don’t Walk Monitoring
Use the arrow pushbuttons to navigate between the settings. Use the
ENTER
pushbutton to toggle the setting. Press the
ESCAPE
pushbutton to exit. See Section
2.6.1
for more detailed information on Flashing Don’t Walk Monitoring.
FLASH DW MON ENABLED
– When this feature is enabled the monitor will check Flashing Don’t Walk (channel Red) of
the channels configured as Channels With Pedestrian Displays, to confirm that they do not conflict with other Greens,
Yellows, or Walks at the intersection. When a fault is detected due to this feature, it is displayed as a Conflict and the
channel with a flashing RED input that was involved in the detected fault will be flashing its RED LED.
CHANNEL 1-16 CHANNELS WITH PEDESTRIAN DISPLAYS SETTINGS
– Enabled is indicated by a
Y
and disabled
is indicated by a dash
(
−
). In Type 12 mode of operation, any enabled channel will have its walk input removed from the red
fail test. The factory default for the channel settings of this feature is all channels disabled.
4.6.2.1.7.5
Flashing Yellow Arrow Left Turn Settings
The Flashing Yellow Arrow monitoring routines in this monitor are very flexible but there are some requirements on how the
field wiring is connected to the monitor. The protected indications (Green Arrow, Yellow Arrow, and Red Arrow) must all
be connected to the same channel of the monitor. The flashing Yellow Arrow may be in a channel by itself or use the Yellow
indication of a pedestrian channel. See Section
2.6.3
for more detailed information on Flashing Yellow Arrow Monitoring.
See Reno A&E Application Note AN-005 for more information and detailed examples.
