CLEAR ALL SETTINGS
The Clear All Settings function can be used to quickly configure the monitor with all settings set to OFF.
Use the arrow pushbuttons to select
YES
and press the
ENTER

WIZARD
IMPORTANT: It is the users responsibility to confirm that the settings generated by the wizard are
appropriate for the actual intersection.
The wizard is used to quickly configure a monitor for intersections using standard dual ring phasing. The first
screen is a reminder that the settings generated by the wizard are based on the information provided. Therefore, if
you do not provide the correct information, the wizard will probably not generate the correct configuration.

GENERAL QUESTIONS
ANY LED SIGNAL HEADS – If any LED signals are used at the intersection select
YES
. If all indications are
incandescent select
NO
.
PED CHANNELS – Selects the pedestrian channels. The choices are:
TS1
– The Walk indication is in the same
channel as the vehicle throughs (Type 12 operation) and the Don’t Walks are not monitored.
9-12
– The pedestrian
indications are connected to channels 9 through 12.
13-16
– The pedestrian indications are connected to channels
13 through 16.
PED CH REDS TIED HIGH – If TS1 is selected for PED CHANNELS this item will show
N/A
and cannot be
selected. Otherwise, select whether the pedestrian channel Red (Don’t Walk) inputs are tied to AC+ in the cabinet
or to the actual pedestrian channel Reds. The choices are:
YES
– The Red input is tied to AC+ and the Don’t
Walks are not monitored.
NO
– The Red (Don’t Walk) inputs are connected to the Don’t Walk indications.
USE EXTERNAL WATCHDOG – If the cabinet will use the external watchdog feature select
YES
otherwise
select
NO
.
LEFT TURN CONFIGURATION – There are three selections
PROT, MMU2, CONF
.
PROT
This left turn is a standard protected left turn movement. This is the default left turn type.
MMU2
Allows the selection of sixteen FYA configurations types (A thru P). This includes the eight
Flashing Yellow Arrow (FYA) configuration types (A thru H) defined in NEMA TS 2-2003
(R2008) Amendment 4-2012. When a FYA configuration type is selected the following menu
will display:
FYA CONFIGURATION – If
NO
is selected the Flashing Yellow Arrow permissives and the
permissives for the yellow following the FYA are derived from the channel with the FYA
driver. IF
YES
is selected the Flashing Yellow Arrow permissives and the permissives for the
yellow following the FYA are derived from the opposing thru channel.
ALLOW CONCURRENT YEL – If the Yellow arrow for terminating the Flashing Yellow
arrow is allowed to be on at the same time as the Yellow ball for the opposing through
movement, select
YES
. If the Yellow arrow and the Yellow ball will never be on at the same
time, select
NO
. This will be the same for all Flashing Yellow arrow left turns.
EASY FYA PROGRAMMING – If
NO
is selected then permissive jumpers are required
between the FYA channel and the associated protected channel. If
YES
is selected then the
permissive jumpers are required between the FYA channel and the associated protected
channel. The FYA channel follows the permissive of the associated opposing thru.
IGNORE FYA UNUSED - If
NO
is selected the unused signal indications in a FYA application
are monitored for all expected fault conditions. If
YES
is selected the unused signal indications
are ignored, and will not cause a fault state.
IGNORE YEL TRAP - If
NO
is selected then the yellow following a FYA and the opposing
thru green will conflict. If
YES
is selected then all yellow following a FYA and the opposing
thru green will not conflict. A YES allows a faster preemption handling cycle if in FYA
DISABLE FLASH RATE- If
NO
(default) is selected flash rate monitoring is active. If the
FYA is on for greater than 700 milliseconds, the MMU2 will fail with a Dual Indication failure.
Bit 81 of the Type 129 Response Frame will be set to 1 to indicate a flash rate failure. If
YES
is
selected and a FYA is on for more than 700 milliseconds the FYA will be treated as a solid
yellow arrow indication.
