Ethernet
ENET1
This Ethernet Port can connect 100 Mbs between the controller and external devices.
Ethernet communication supports NTCIP and ECPIP protocols. Settings for these two protocols are
under System Protocol in the center of this screen. You configure Ethernet UDP Port for NTCIP in
System Protocol, NTCIP. The UDP port for ECPIP is fixed at 2101.
Note: Contact your Internet Protocol (IP) specialist to determine the correct setting for each of
the programmable parameters defined below.
Parameter

Description

Address (0-255)

A unique address used by the Ethernet interface. The format follows the
Transmission Control Protocol/internet Protocol (TCP/IP) standard dot notation.
When used, the address must be assigned from the same subnet as the other
network devices with which it may communicate, such as a system controller or
File Transfer Protocol (FTP) server. If the controller is connected to an IP router,
the address must be valid for that router.

Net Mask (0-255)

The Net Mask must be the same as the other devices on the IP subnet to which
the controller is attached (when an Ethernet interface is being used).
This configures the ethernet port ENET2.

Database

This screen gives access to Consistency and Warning Checks and has a Database Copy Utility.

What is a Warning Check?
In the Cobalt controller, following a database download or object data alteration via key board,
the controller runs Consistency Checks to look for critical errors. If it detects errors, they must be
corrected or all database changes are discarded.
After you program the controller, it may appear that a certain feature does not operate correctly, but it
may be because of incorrect programming. To call attention to a possible incorrect programmed entry,
the controller generates a Warning. The controller generates a Warning if, in the opinion of Econolite,
you override the programmed parameter setting from a database with an unusual selection, or select
a combination of programmed values that may not give you the operation you probably expect.
Warning Checks are intelligent diagnostics designed to tell you of data entries that, by themselves or
in combination with other entries, may result in unexpected operation.
Important: One thing to keep in mind: a warning is not an error.
Occasionally, it could be that programming results in incorrect operation, but is acceptable to you
because it provides a benefit to you that compensates for an occasional operational anomaly. For
example, some users routinely program Walk and Pedestrian Clearance times that exceed phase
split times in coordinated operation because there are very few pedestrian calls and the user does
not mind the occasional coordinator resynchronization that follows the service of a pedestrian call.
Because we cannot possibly anticipate what you have in mind, it is left to you to decide what action, if
any, to take to correct the situation that caused a Warning message.
Cobalt by Econolite

23
* Cobalt Programming Manual - LIMITED DISTRIBUTION *

25/11/2013

Initially, the software framework and a limited set of diagnostics will be available. Warning Checks are
viewed as a long-term work-in-progress. These checks will be expanded as users and developers
find situations that cause an unexpected controller operation.
Select the condition for your application:
Database Hardware CRC Lock (Yes, No)
Request Database Download (Yes, No)
Automatic Backup to Datakey (Yes, No)
Enable VIOT Capture (Yes, No, Y + C)

Note: When you program Cobalt, you select Commit as necessary to enable the change to the
database. For an explanation of Transaction Mode (that runs when you make a critical change to
programming), refer to the Help for Home > Phase Order > Phase Order.

Transaction Mode
IMPORTANT: To program an ASC/3 or an ATC 2070 Controller with ASC/3-2070 or ASC/3ATC software, it is necessary for you to understand Transaction Mode. Before you
proceed, read and understand this section about Transaction Mode.

Introduction
A Cobalt Controller contains a wide variety of Traffic features designed to give you maximum flexibility
in configuring an intersection. This broad base of applications requires database functions which, in
many cases, depend on other data entries to work properly. To ensure that critical data is entered
properly, the controller must run consistency checks on the database. These tests make sure
interrelated database functions are compatible with each other.
The consistency checks are done in what is called Transaction Mode.
Some data is relatively independent, such as timing entries. Other data, like the selection of controller
startup phases, depends on the phases and compatibilities of programmed sequence. These data
must be done within the Transaction Mode. Another type of data that triggers Transaction Mode is
one that has 2 or more functions — examples include HH:MM or 10.70.10.51.
Controller data may be modified manually via the keypad or remotely using SNMP/STMP messages.
In either case, critical data must be protected from incorrect or inconsistent changes.

Changing Data with the Keypad
If you attempt to modify a critical piece of data with the keypad (for example, controller start-up
phases), the controller automatically goes to Transaction Mode. A warning message will appear
on the display and the top line of the screen will flash. At this point, all changed data is stored in a
temporary buffer until you exit Transaction Mode.
When the Cobalt is in Transaction Mode, the controller gives you audio-visual indications as
explained below:
• Over the Database icon in the Status Bar, there is a rotating circular symbol and the selection of
Rollback (do not make a database change) or Commit (add the change to the database)
• As a reminder, if there is no key activity for 30 seconds, the controller will produce a continuous
beep sound and a pop-up reminder message will be displayed. This reminder is the same as the
message seen when you first triggered transaction mode and serves as a reminder to users who
Cobalt by Econolite

34
* Cobalt Programming Manual - LIMITED DISTRIBUTION *

25/11/2013

might not remember how to exit transaction mode. Any key activity will stop the buzzer but selecting Rollback clears the transaction mode message.
• The front-panel LED will blink Fast Yellow

To exit Transaction Mode without saving the data, select Rollback.
To initiate the VERIFY state, once you have completed all of the changes, select
Commit.
During the verify state, the controller runs its consistency checks on the newly entered data. If
the data passes, then the changes are copied to the active database and Transaction Mode is
terminated. If the Consistency Checks find an error (for example, incompatible Startup Phases), then
the controller displays a description of the problem and gives you the option to disregard/throw away
all changes or to go back into Transaction Mode to correct the data.
Although the controller’s display will show your changes, it is important to note that those changes
will NOT take effect in the controller’s operation until Transaction Mode has exited. Also, if you cycle
power during Transaction Mode, then upon start-up all modified data will be lost. This is because the
modified data was only stored in the temporary buffer and never officially copied to the database.
Please note that not all data changes force the controller to Transaction Mode. Timing parameters
such as Minimum Green and Yellow Clearance may be modified as soon as you enter the data.
These changes take effect immediately.

Changing Data with SNMP/STMP
You may also change the Cobalt database with an SNMP or STMP SET message from Central. In
this case, it is Central’s responsibility to force the controller into Transaction Mode if critical data is to
be modified. Before SETs will be accepted on any P2 (or critical) objects, Central must send a SET to
dbCreateTransaction.0, changing it to a value of 2- transaction. At this point, Central may send any
number of SETs to database objects. These values are stored in a temporary buffer, the same as with
the manual keypad entry.
Once Central has completed its SNMP/STMP SETS and is ready to commit the new data to
the database, Central must send a 3-Verify to dbCreateTransaction.0. Cobalt will run the same
Consistency Checks as for the Keypad entry. Once completed, the controller internally sets the
transaction state to 6-DONE. If no errors were found, the new data is automatically copied to the
active database. Otherwise, the data is held in the temporary buffer until the discrepancies have been
corrected. (Central can see the error messages by doing a GET on the object, dbVerifyError.0.)

Summary
The Cobalt contains many database elements which are dependent on other entries. To ensure
proper controller operations, these dependencies must be checked before data is committed to the
active database.
Two methods exist to modify the controller’s database- keypad and NTCIP communications. Both
require Cobalt to enter a Transaction Mode state to allow Consistency Checks to run on the modified
data. If you cycle power BEFORE these checks can be run, then the modified data will be lost.
Also note that while the changes may appear on the controller’s screens, those values will NOT be
implemented in the controller’s operation until Transaction Mode is complete. That is, the Consistency
Check must be done before the new data is officially copied to the database.

Protected
The Protected Overlap is a movement having a protected green arrow (no conflicting phases timing).
Note: When a phase has protected overlap phase assignments, Modifier, Lead, and Trailing
assignments are ignored (inhibited).
Select the phases for this type of overlap.

Ped Protected
The Pedestrian Protect option provides for the specification of phase pedestrian movements that
cannot be serviced while the overlap is active. If a pedestrian call is present on a pedestrian protected
phase when that phase becomes the phase next selection, the overlap is terminated while the ring
transitions from the timing phase to the phase with the protected pedestrian service. If a pedestrian
call is not present when the pedestrian protected phase becomes the phase next selection, the
overlap remains active if an included phase is timing or a phase next selection. Should a pedestrian
call be input while the ring is in yellow change or red clear on the way to the pedestrian protected
phase, the overlap is not terminated until the pedestrian protected phase starts and then only if there
is enough time to terminate the overlap and time the pedestrian movement before the phase will max
out.
Select the phases for this type of overlap.

Not Overlap
The Not Overlap option is provided to inhibit the activation of an overlap when selected phases are
timing. If an overlap is active when a call is placed on a not overlap phase, the phase is not allowed to
time until the overlap is terminated. If the order of rotation would normally allow the not overlap phase
to time, overlap termination will be initiated even if an overlap included phase is timing or a phase
next selection.
Select the phases for this type of overlap.

Lag X Phase
The Lag (Trailing) Overlap Phases option identifies which phases are to time programmed trailing
green, yellow, and red. If Trailing phases are defined, only those phases will time trailing green,
yellow, and red when they advance to yellow change and no other included phase is timing or a
phase next selection. If no Trailing phases are defined, then trailing green, yellow, and red are
disabled.
Select the phases for this type of overlap.

* Cobalt Programming Manual - LIMITED DISTRIBUTION *

25/11/2013

Lag 2 Phase
For Lead Overlap Phases, when the overlap is active, the last timing overlap included phase is
advancing to yellow, no included phase is a phase next selection, and a Lead phase (that is not an
included phase) is next, trailing green, yellow, and red will be timed. This operation may be thought of
as timing a lagging overlap when proceeding to a particular phase.
When the overlap is not active and a Lead phase that is an included phase is a phase next selection,
overlap advance green will be displayed. Overlap advance green output starts, defined by the ADV
GRN time, when the phase of the ring that is transitioning to the included Lead phase begins its
yellow service.
Note: The Adv Grn time takes effect only if the lagging Yellow time is non-zero.
Select the phases for this type of overlap.

Lag Green, Yellow, Red
For Lag (Trailing) Green, Yellow and Red times, normally, if an included phase is terminating and no
other included phase is timing or a phase next selection, the terminating included phase’s yellow and
red are also output to the overlap. Trailing Green, Yellow, and Red provide a means of extending the
overlap’s green and then timing a specified yellow and red. When the last timing overlap included
phase begins its yellow change, the overlap’s green interval is extended by the specified Trailing
Green time. After Trailing Green has timed, Trailing Yellow and Trailing Red times are used to time the
overlap’s yellow change and red clearance intervals.
Note: Lagging times take effect only if the if the Green and Yellow entries are both non-zero.
Range is 0 to 25.5 seconds.

Adv Grn
Advance Green specifies the minimum amount of overlap advance green to be displayed before a
phase next selected included lead phase is started. If the amount of advance green is less than the
yellow change time and red clear timed by a ring before its phase next included lead phase can be
started, the overlap advance green is extended. If the amount of advance green is greater than the
yellow change and red clear timed by the ring before the overlap lead phase next selection would
normally start, the terminating ring phase’s red clearance is extended until the advance green time is
satisfied.
Overlap advance green output starts when the phase of the ring that is transitioning to the included
Lead phase begins its yellow service.
Range is 0 to 25.5 seconds.

Flash Green
Flash Overlap Green is specified for each included phase of an overlap and defines the rate at which
the overlap green interval is to flash when the included phase is timing.
For each phase, select a flash rate:
NF = no flash or phase is not an included phase for the overlap
F1 = flash at 1 pps.
F2 = flash at 2.5 pps.
F5 = flash at 5 pps.
The flash is extended across the transition from one included phase to another included phase if their
flash rates are the same.
Overlap green will be solid when transitioning between included phases that have different flash
rates.

PPLT/FYA Type Overlaps
The overlaps page configures unique signal drivers outside of common phase control such as right
turns or permissive left turns.

Types of Overlaps
You can program four types of overlaps:
• Normal
• -Green Yellow
• PPLT/FYA
• Econolite
Normal and Minus Green Yellow operate per the requirement specified in NTCIP 1202 paragraph
2.10.2.2. PPLT/FYA uses overlap so you can program Protected Permissive left hand turns. Type
Econolite identifies overlaps that supplement the Normal overlap with the Econolite-specific options.

Overlap Outputs for the PPLT/FYA Type of Overlap
PPLT/FYA = Protected/Permissive Left Turn Flashing Yellow Arrow
This is a special Econolite overlap type for Protected/Permissive Left Turns using the Flashing Yellow
Arrow. It changes programmed controller outputs to meet NEMA specification.
To program a PPLT/FYA type of overlap, in the Type drop-down menu, select PPLT/FYA.
Note: Throughout these procedures, select Commit as necessary to enable the change to the
database. For an explanation of Transaction Mode (that runs when you make a critical change to
programming), refer to the Help for Home > Phase Order > Phase Order.

assumed that opposing queued vehicles will not provide adequate headway. This
delay timer will not apply during preemption. The channel output will be red.
Note: To make sure that the flashing interval duration is at least two seconds,
a phase Hold is applied to make sure the parent opposing through movement
does not terminate too soon. If the opposing through phase has reached yellow
clearance before the delay start timer expires, then the FYA channel output
remains in red.

Information about Pedestrian Overlaps
Each pedestrian overlap output replaces the selected phase pedestrian output. This gives a total of
16 possible pedestrian overlaps. When a pedestrian overlap programming consists of two or more
phases, the overlap operates as follows:
Phase next decision is made at the end of walk. If other rings have pedestrian overlaps, with different
walk times and a barrier is being crossed, the phase next decision is made at the end of the longest
walk with the other rings being held at the end of walk.
At the end of walk, if the phase next has a pedestrian movement with a demand, which is part of the
pedestrian overlap, the pedestrian clearance will not start or time. The phase terminates normally
with walk displayed. In a pedestrian overlap, the walk will time in the first phase and every additional
phase until a non-included phase next terminates the walk and initiates pedestrian clearance.
Whenever a pedestrian overlap included phase is timing a walk or the controller is transitioning
from a walk end condition on a timing phase to a walk service on another overlap included phase,
the overlap will display walk. When no ped included phase is timing a walk and is not a phase next
selection with a ped call, the overlap will display pedestrian clearance as long as any included ped
phase is timing a ped clearance. When all included ped phases are in don’t walk, the ped overlap will
show don’t walk.

Preemption
A preemptor can terminate a pedestrian overlap at any time. The preemption can override a
preempted phase ped walk and clearance time and those override times will be used to terminate the
overlap. The walk and Pedestrian Clearance times are those programmed for the preemptor (Home >
Preemption > Entry > Minimum Phase Service Timings > Pedestrian and Walk). The pedestrian
overlap will terminate even if the phase is halted in red transfer.

Coordination
If a coordinated phase is part of a ped overlap, the phase must be non-actuated and Walk Rest
Modifier must be applied.

Note: Observe the programming notes listed below:
• Detectors assigned to a phase may be used as a speed detector.
• One-detector speed calculation can use even or odd-numbered detectors.
• Two-detector speed calculation requires an odd-numbered detector to be assigned. The next even-numbered detector is the second detector for the speed
calculations.

One/Two
Detector

Select 1 or 2 speed calculations for Local Detectors 1-16.
1. One-detector Speed. The detector encountering a passing vehicle starts a
counter by an actuation and stops the counter when it is deactivated. Speed is
calculated using the vehicle travel time over the detection zone and the vehicle
length.
2. Two-detector speed calculation. The first detector encountered by a passing
vehicle is the Start Detector and the second is the End Detector. A travel time
counter is started by an actuation of the Start Detector and stopped by an
actuation of the End Detector. Speed is calculated using the vehicle travel time
and distance between detectors.
Note: Observe the programming notes below:
• The Length entry inch calculates speed in miles per hour. cm (centimeters)
calculates speed in kilometers per hour.
• Speed that reads back to the arterial master is used to generate a log of speed
readings in low, nominal, and high speed bands.

Vehicle Length

Average Vehicle Length
0-999: Use the scrubber to enter the average vehicle length in centimeters or

determine the one-detector speed.

0-999 inches
0-999 cm.

Trap Length

0-999: The effective Trap Length distance.
For one-detector speed trap calculation, it is the effective detection distance from
start edge to stop edge of detection.
For two-detector speed trap calculation it is the effective detection distance
between two detectors from start edge to start edge of detection.
Note: The effective detection zone will differ from physical length due to a
variety of electrical and magnetic factors. Enter the length that produces the
most representative speeds.

• The top row is Ring 1 and the bottom row is Ring 2
When programming the phases, remember:
• You can have one phase per ring.
• For two phases:
One must be in Ring 1 and the other in Ring 2
They must be in the same barrier group
You cannot put two phases in different barrier groups.
Flash Color (for load switch power up only) -The flash color buttons represent Channels 1 thru 16.
Since channels 9 thru 12 are pedestrians and overlaps so they are programmed as Dark.
Red: Indicates that the channel will flash red. These load switches must represent compatible
MMU channels.
Dark: Indicates that the channel will be dark.
Yellow: Indicates that the channel will flash yellow. These load switches must represent
compatible MMU channels.
Automatic: Indicates that the channel color will follow Automatic Flash. If any PWR is
programmed R or Y, then the controller cannot have A programmed for any other PWR channels.
Important: It is your responsibility to match this Flash Color load switch setting with the actual
cabinet flash output.

by Steps to Reduce to calculate the number of 1/10 second
cycles timed between each reduction step. By the time the Time
to Reduce interval has completed its timing, vehicle extension in
effect will have been reduced the Minimum Gap Time.
Linear reduction: When gap reduction starts and Steps to Reduce
is zero, Minimum Gap Time is subtracted from the vehicle
extension in effect and that value is divided by the product of Time
to Reduce multiplied by 10. The result is subtracted from vehicle
extension in effect every 1/10 second until vehicle extension in effect
is reduced to the Minimum Gap Time.

Home > Preemption
Overview
You can program up to 10 Preemption Plans. A programmed Preemption Plan is used when it is
enabled (its icon is highlighted in blue) and not used when it is disabled (its icon has a gray background). Service is prioritized so that the lowest number preemptor with Priority Override set to Yes
(in the Entry screen) has the highest priority or service can be programmed as first come, first served.

Initial Overview Screen

In the screen above, notice:
• Preemption Plan 1 is a Rail type and Preemption Plans 3, 4 and 7 are Emergency type.
• If a Preemption Plan is enabled, it is highlighted in blue. Preemption Plans 3 and 4 are enabled
and Preemption Plans 1 and 7 are disabled (gray background).
To start to program preemptions in this screen, select a Preemption Plan (1 thru 10) in the Preemption
Plan fields.
• For a Rail preemption, this is the first of six screens (Overview, Entry, Track Clear, Dwell, Cycle
and Exit).
• For an Emergency preemption, this is the first of five screens (Overview, Entry, Dwell, Cycle and
Exit).

• Feature Type Filter: Rail preemption is selected.
• There is a Track Clear tab after the Entry tab (because it is a Rail preemption).
Note: For a Rail preemption, make sure you program the parameters in the Track Clear tab. If
you do not program the Track Clear screen, the type changes to Emergency (as written in red in
this screen).
• The preempt input is not filtered (filtering is bypassed):
–– No Call Method is selected.
Note: If you want to bypass the filter of the input and Solid or Pulsing is selected, tap the
selected field to de-select it. But, if you want to filter the input, select a Call Method, Solid or
Pulsing.
–– The hard-wired preempt Input 1 routes directly to Preemptor 1 (when the input is bypassed,
the number of the hard-wired input and the number of the preemptor is the same).
–– The Filtered Input is automatically set to 0 because the filtering for this Preemption Plan is
bypassed.
• Active Status (the output during a preemption) is F1 pps (a 1-pulse-per-second signal).
• Min Duration (the required minimum time that the preempt run must be active) is 10 seconds.
• Only During Dwell is No (a restriction of the Output Status to only during the Dwell/Cycle interval is disabled).
• There are no Special Functions enabled.
• This Preemption Plan disabled (gray background); to enable this plan, select [Enable Plan], then

–– The Call Method is Pulsing for the controller to filter the input for a pulsing preempt signal
from an emergency vehicle.
–– For this example, the Filtered Input is set to 3 (with the preemptor number the same as the
number of the hard-wired input). But it is possible to select another number (1 thru 10) to
connect this preemptor to a hard-wired input with a different number.
• Active Status (the output during a preemption) is Solid (a solid signal).
• Min Duration (the required minimum time that the preempt run must be active) is 10 seconds.
• Only During Dwell is No (a restriction of the Output Status to only during the Dwell/Cycle interval is disabled).
• There are no Special Functions enabled.

Locked Preemptor Call During Delay
A preemptor may have either Locked (Yes) or non-locked (No) detector inputs.
The non-locked parameter is in effect only during delay time.
No (Detector not Locked): If a preemptor call is dropped during delay time, the
preemptor is not serviced.
Yes (Detector is Locked): If a preemptor call is dropped during delay time, the
preemptor is serviced. The call is Locked until the preemptor is serviced.

Optimized
Delay

Optimized Delay Entrance Option
Note: To enable this function, you must enter a non-zero value for the Delay Time
in this screen. If the Delay Time is set to 0, this parameter is grayed out.
Select from the drop-down menu to enable/disable the optimized delay to decide
whether or not to apply omits to movements, as explained below:
Off: Disabled
On: Always Enabled
Time of Day: Enabled only by Time of Day. This function is then controlled by
Home > Event Plans > Advanced > Allow Optimized Delay (set to Yes or No).
When this is enabled, and a preempt is activated, the preemptor compares
its delay time to the minimum time required to service phase and pedestrian
movements. If the amount of time left in the delay timer is less than the amount
required to service a phase or ped, then the preemptor applies omits to those
movements.
When all phases have been omitted because of lack of time, the preemptor will
direct the controller to the preempt Entry Phases so it can start the preempt as
soon as the Delay Timer reaches 0 (zero).

Priority
Override

Preemptor Overrides Higher Numbered Preemptor Disable
Note: A Higher Priority preempt cannot interrupt a preempt currently entering or
timing Track Clear. The interrupted preempt will complete timing its Track Clear
and only then will it terminate so that the Higher Level Preempt can run.
Yes: Allows this preemptor to override all higher numbered preemptors.
(Example: 2 = Yes overrides 3 through 10)
No: Disables this preemptor from overriding the next active higher-numbered
preemptor.
Example:
• Preemptor 1 is the highest priority preemptor.
• Preemptor 2 has priority over all other active preemptions except Preemptor 1.
• Preemptors 3-6 are equal and are serviced on a first-come, first-served basis.
They all override Preemptors 7-10.
• Preemptors 7- 10 are equal and are serviced on a first-come, first-served
basis.
To program the above example, set Priority Override in the preemption plans as
shown:
1 = No
2 = Yes
3 = No
4 = No
5 = No
6 = Yes
7 = No
8 = No

This is the last part of delay time, during which phases that are not scheduled for
service at the start of the preemption sequence, and all pedestrian movements
are inhibited. This inhibit time must be less than or equal to Delay Time. Zero
entry causes no inhibit time at the start of the preemption sequence.

0-255 sec.

Terminate All
Phases

Preemptor Terminate All Phases
Select Yes or No for the controller to always terminate all timing phases before it
enters a preempt run. This forces an All Red condition before the preempt starts.
Yes: Terminate all timing phases and force an All Red condition before the start of
the activated preempt. Phases will not be terminated if the current Green phases
exactly match the entry phase(s) of the Preempt and the entry phase(s) will not
cause a Yellow Trap for settings that conflict with this as programmed in Home >
Overlap > Details for a PPLT/FYA type overlap.
No: Controller only terminates phases not required by the activated Preempt run.
Note: In this screen, you cannot enter Yes in Terminate All Phases and Yes in
Allow Yellow to Green at the same time because they would be in direct conflict
with one another.
To make a PPLT compatible during preemption, program the designated phase/

Track Clearance Phase(s)
To program phases for Track Clearance, refer to the example before this table.
These are the phases serviced first following Initial Clearance. Each ring will time
according to the Track Clearance Green, Yellow Change and Red Clearance
intervals. Each ring then holds in Red transfer until all have finished their Track
Clearance timing. All rings then advance to the preemptor Dwell interval together.
The Yellow and Red indication will be solid but the green will be as follows:
• Solid: Solid Green when the phase is green.
• F1 pps: Flashing Green at 1 pps when the phase is green
• F2 pps: Flashing Green at 2.5 pps when the phase is green.
• F5 pps: Flashing Green at 5 pps when the phase is green.
Note: Changes in flashing rate will take place when the phase green starts to

Flashing

Dwell Phases Flash During the Dwell Interval
When the preemptor advances to the dwell interval (dwell phases may or may
not be programmed), the load switch outputs behave as follows:
Off: Load switch outputs do not flash.
LDSW (Load Switch): Causes the preemption Dwell phases to flash Yellow while
all other phases flash Red. Dwell Flash operation is limited to one phase per ring
that is also a permissive phase.
Note: This Flash exits to either the Exit Phases or (if no exit phases) to the Dwell
Phases.
Monitor: On NEMA cabinet, controller forces the controller to drop CVM and
puts the intersection into Cabinet Flash. On 300 Series cabinet, for this to
work, Conflict Monitor needs to have watchdog latching disabled. In this mode,
Watchdog can be stopped to produce cabinet flash.

Select from the drop-down menu to enable/disable the preemptor to decide if an
Interrupted Phase will be selected as an exit phase:
Off: Disabled
On: Always Enabled
Time of Day: Enabled only by Time of Day. This function is then controlled by
Home > Event Plans > Advanced > Allow Vehicle Priority Return (set to Yes
or No).
When this is enabled, the preemptor:
1. Calculates the % Green timed of the Interrupted Phases
2. Compares the % Green timed with the % value you entered in % Green
Accepted (bottom of this screen) for the Interrupted Phases
3. If the % Green is less than the % value you entered in % Green Accepted for
a phase, then the preemptor selects that Interrupted Phase as a Veh Priority
Return Exit phase.
For details about the % Green Accepted parameter, refer to the last row of this
table.

Link Preempt

Preemptor to be Linked to this Preemptor
Select a higher priority (lower numbered) preemptor to link to this preemptor. The
linked preemptor will be called when this preemptor completes the programmed
minimum dwell time. The call to the linked preemptor will be maintained as long
as demand for this preemptor is present. Calls to any lower priority or not valid
preemption sequence will be ignored.
The linking preemptor feature allows multiple track clearances or complex
preemption sequences with one preemptor calling another.
Example: Preemptor 3 is linked to 2, it will go through its Track Clearance
interval and start the Dwell interval.
When the Minimum Dwell/Cycle Green time is elapsed, a call is then placed on
Preemptor 2. This transfers control to Preemptor 2. Preemptor 2, in turn, can then
be linked to Preemptor 1.
This example creates a possibility of five phase clearance prior to getting to the
Preemptor 1 Dwell interval and timing its phases.
Important: The Max Presence time for each preemptor must be taken into
account when this feature is used to make sure the correct operation occurs.

Important: If these values are set to zero and the Guaranteed Minimum
Times (Home > Timing Plans > Guaranteed) are also zero, the indication will
terminate immediately when it enters preemption, regardless of the time on the

Queue Delay
Recovery

Queue Delay Recovery Option
Select from the drop-down menu to enable/disable as described below:
Off: Disabled
On: Always Enabled
Time of Day: Enabled only by Time of Day
When this is enabled, the preemptor:
1. Checks phase wait time (WT) since last demand.
2. Checks the number of cars waiting for service (CW).
3. Selects the phases with the greatest WT x CW values as possible Exit Phases,
one phase per ring. If the weighted delays for two phases are equal, the next
in the sequence is served first.
Example: Phase A wait = 50 secs with 10 cars in line; phase B wait = 80 secs
with 7 cars in line. 80 x 7 (560) > 50 x 10 (500) so Phase B is selected.
One phase per ring and concurrent group are selected as exit phases.
Note: Also, to include a phase in the selection process, you must set
Preempt Queue Delay Calculate to Yes in Home > Detection > Vehicle

Exit Phases

Preemption Exit Phase(s)
Select exit phases (1 thru 16) to enable the operation described below.
For the phases you select as exit phases, the preemption sequence terminates
when all exit phases are timing.
If you do not select an exit phase, there are two possibilities:
• If the Preemption-to-Coordination option is not active, the preemptor terminates immediately and exits from the Cycling interval directly to normal controller operation.
• If the Preemption-to-Coordination option is active, the preemptor will terminate
and exit from the Cycling interval directly to the lowest priority phase(s) that
have an open coordination permissive window. This allows the preemptor to
exit directly into coordination without requiring a pickup cycle or transition.
Note: Exit phases must be permissive and compatible with each other.

Exit Options

Preemption Exit Options for Timing Plan
Note: In the descriptions below, Timing Plan refers to the timing plan set in the
Timing Plan parameter in this screen. For Exit to Phase Once and Exit to One
Cycle to operate, you must set a Timing Plan. Exit to Coord, however, operates
with or without a Timing Plan.
From the drop-down menu, select the next phase after exit from a preemption:
Off: Disable
Exit to Coord: The preemptor exits directly into the coordination sequence and
does not require a pickup cycle when the coordinator is active.
Exit to Phase Once: The preemptor exits directly to the exit phase with a Timing
Plan. This preempt exit Timing Plan is used only for the timing of the exit phases.
Exit to One Cycle: The preemptor exits to Free for one cycle by a Timing Plan.
Then the controller returns to Coordination mode. One cycle = all phases that
had external calls when the preemption exited; recalls or internal calls are not
included.

Walk Delayed to Local Zero

Enable the coordinated phase walk to be prevented from starting until the local zero.
Normally, the coordinated phase walk starts as soon as it is able to after the last
permissive is closed.

ECPI Coordination

Allows ECPI coordination operation and parameters

Local Zero Override

Allows the non-coordinated phase/s to use a portion of the coordinated phase split
before the coordinated phase becomes green. The movement continues to run and
remain in sync with the Local Master Dial until the coordinated phase would violate the
Yield point. At that time, the Local Dial stops until the coordinated phase is green and
reports a local zero error.
Note: Typically used on short cycles that have seldom used non-coordinated
movements.

performs as follows: If a local cycle can be in sync, make it in sync.
Smooth: Is accomplished by adding or subtracting a maximum of 17% of cycle
length per cycle (Ref NTCIP 1202 2.5.2 Integer 3). Econolite lets you change
this factor by changing the Dwell / Add Time when it is non-zero.
Add Only: Is accomplished by adding a maximum of 17% of cycle length per

Split Time

Split Intervals of the Cycle Time
Here you divide the cycle time into sections (split intervals) to assign the
maximum amount of time to each timing phase during coordination.
Important: Observe the Cautions listed below.
If ECPI Coordination is set to No (in Home > Coordination > Coordination
Options), the coordinator will go free when:
• Entering zero for any active phase-split.
• Entering phase-splits that are smaller than the minimum phase time
• Entering splits that exceed the cycle length.
If ECPI Coordination is set to Yes (in Home > Coordination > Coordination
Options), then:
• Entering zero for any active phase-split will omit that phase.
• Entering phase-split(s) that are smaller than the minimum phase time(s) or that
exceed the cycle length may cause loss of coordination.
Note: A Phase Split is the maximum amount of time available to a phase during
coordination if Floating Force-Offs is in effect. If using Fixed Force Offs are in
effect and the split timer starts early due to time left over from preceding phases,
the phase can be extended by demand up to the force-off point. The maximum
time available can only be lowered if you have a Max Select (Max 1, 2 or 3) (set
in Home > Coordination > Coordination Options > Default Split Max Select
or in Home > Event Plans > Pattern > Max Select) and if the max time in effect
is shorter than the split.

Permissive
Period 1

Manual Vehicle Permissive Period 1 (VPP1)
This is the portion of the cycle length during which phases other
than the coordinated phases may be serviced. This period begins
timing at the coordinated phase Yield Point. If Vehicle Permissive
Period 2 (VPP2) or Vehicle Permissive Period 2 Displacement
(VPP2D) is equal to zero, all non-coordinated phases may be
serviced during this period. If VPP2 or VPP2D are not equal to
zero (dual permissive operation), then only the first phase(s)
that follows the coordinated phase(s) (first permissive phases) is
serviced during this period.
Use the scrubber to enter 0 to (Cycle time minus 1). The units of
measure are the same as set in Split Unit (seconds or percentage)

1 to (Cycle time minus 1) enables the Vehicle Permissive Period
1 (VPP1) that is the portion of the cycle following Yield in which
phase(s) following a coordinated phase may be serviced.
Note: If VPP2 or VPP2D is zero, all phases will be serviced during

Period 2

Manual Vehicle Permissive Period 2 (VPP2)
This is the portion of the cycle length during which phases other
than the coordinated phases and those directly following may be
serviced. This period begins timing immediately after the Vehicle
Permissive 2 displacement period. Only phases other than
those serviced during the first permissive period can be serviced
because phase omits are applied to the first permissive phase(s).
Use the scrubber to enter 0 to (Cycle time minus 1). The units of
measure are the same as set in Split Unit (seconds or percentage)
in Home > Coordination > Coordination Options.
1 to (Cycle time minus 1) enables VPP2 that starts after VPP2D
has timed out after the Coordinator Yield. It is the portion of the
subsequent cycle that phase(s) other than those that directly
follow coordinated phase(s) may be serviced.
Note: If VPP2 or VPP2D is zero, all phases will be serviced during

Parameter

Description

Permissive Operation

The coordinator is programmed to calculate permissive periods by one of three
operations: Automatic, Dual and Single; these are described below.

Auto Permissive

Automatically computed permissive period. Each sequential phase is
automatically assigned a vehicle and pedestrian permissive period. The length
of the vehicle permissive period is determined by the phase split interval
and phase minimum time. Phase minimum time is equal to auto permissive
minimum green, bike minimum green, or phase minimum green, whichever
is larger, plus the yellow and red clearance time. Auto permissive green time
allows you to set the phase minimum green to a low value, yet still ensures that
the auto permissive period provides sufficient green time if the controller yields
to the phase at the end of the permissive.

Dual Permissive

A permissive operation that requires operator data entry of three parameter
values: Manual Vehicle Permissive Period 1, Manual Vehicle Permissive Period
2 and Manual Vehicle Permissive Period Displace. During this permissive
operation, the Vehicle Permissive Period 1 times first. This period begins at
the yield point. Vehicle Permissive Period 2 begins timing immediately after
an adjustable time period (Vehicle Permissive Period 2 Displacement). During
the Vehicle Permissive Period 1, only those phases immediately following
the coordinated phases are serviced. If the controller yields during the first
permissive, all remaining calls are serviced in normal sequence and the second
permissive period is not used.

Single Permissive

Single permissive operation is selected by setting the Vehicle Permissive 2
displacement to zero. Only the Vehicle Permissive Period 1 and its associated
pedestrian permissive period are timed and begin timing at the yield point.
During the Single Permissive period, the controller yields to any phase.

Permissive Period End
Point

End Point = (Split Sum) - (K Phase Clear) - (Perm Phase Min Green and Clear)
Where:
• Split Sum = Sum of splits from coordinated through permissive phases,
inclusive.
• K Phase Clear = Coordinated phase Yellow + All Red (If Walk Rest Modifier
input = TRUE).
• K Phase Clear = Coordinated phase Ped Clear + Yellow + All Red (If Walk
Rest Modifier input = FALSE).
• Perm Phase Min Green and Clear = Permissive phases minimum green +
Yellow + All Red.
• Perm Phase Min Green = Permissive Phase minimum green or (Walk + Ped
Clear), whichever is greater.

Yield Point

Yield Point = Coordinated phase split interval - Coordinated phase clearance
time (Pedestrian and vehicle clearance times).

Actuated Yield Point

Actuated Yield Point = Coordinated phase split interval - Coordinated phase
clearance time(s) – Ring split extension time.

Offset Point

The offset entry establishes the offset point to the:
• Lead: Referenced the start of the Local Dial to the start of the first coordinated phase green.
• Lag: Referenced the start of the Local Dial to the start of the last coordinated
phase green.
• Yield: Referenced the start of the Local Dial to the start of the first coordinated phase yield.
• Yellow: Referenced the start of the Local Dial to the start of the first coordinated phase yellow.

Yield Points

The coordinator uses multiple yield points; one yield point is computed per
ring. There may be four distinct yield points. Hold and Yield are independent
calculations based on offset, coordinated phase splits and coordinated phase
timing.

Minimum Controller
Cycle Time

The shortest possible cycle length allowing all phases to time their minimum
vehicle and pedestrian interval times.

Dual Coordination

Dual coordination is established when the dual coordination input is TRUE.
This forces the crossing artery (Crossing Artery Pat) phase splits to be used
and places a continuous vehicle demand on the call-to-non-actuated 2 (CNA II)
phases.

Split

Split Intervals of the Cycle Time
Here you divide the cycle time into sections (split intervals) to assign the
maximum amount of time to each timing phase during coordination.
Important: Observe the Cautions listed below.
If ECPI Coordination is set to No (in Home > Coordination > Coordination
Options), the coordinator will go free when:
• Entering zero for any active phase-split.
• Entering phase-splits that are smaller than the minimum phase time
• Entering splits that exceed the cycle length.
If ECPI Coordination is set to Yes (in Home > Coordination > Coordination
Options), then:
• Entering zero for any active phase-split will omit that phase.
• Entering phase-split(s) that are smaller than the minimum phase time(s) or
that exceed the cycle length may cause loss of coordination.
Note: A Phase Split is the maximum amount of time available to a phase during
coordination if Floating Force-Offs is in effect. If using Fixed Force Offs are in
effect and the split timer starts early due to time left over from preceding phases,
the phase can be extended by demand up to the force-off point. The maximum
time available can only be lowered if you have a Max Select (Max 1, 2 or 3) (set
in Home > Coordination > Coordination Options > Default Split Max Select
or in Home > Event Plans > Pattern > Max Select) and if the max time in effect
is shorter than the split.

Preference 1 and 2 Phase Unused Split Allocation
0: Deselect or
1-16: Select a phase to allocate unused split time.
Important: For this feature to operate, make sure that the Force Off parameter
is set to Float (in Home > Coordination > Coordination Options > Default
Force Off or in Home > Event Plans > Pattern > Force Off). If Force Off is set
to Fixed, these Preference Phase 1st and Preference Phase 2nd parameters are
not shown in this screen.
You can program any unused split time from an Initial phase to time in a
Subsequent/Preference phase, as needed. The Subsequent/Preference phase
must be in the same ring as the Initial phase.
Procedure:
1. In Preference Phase 1st, select the field under the number of the phase you
want for the Initial Phase (1-16).
2. Use the scrubber to select the number of the Subsequent/Preference Phase
(1-16) to time any unused split time from the Initial Phase.
3. To program another Subsequent/Preference phase, repeat Steps 1 and 2 with
Preference Phase 2nd.
Note: A value of 0 in Preference Phase 1st / Preference Phase 2nd means that
the related phase is not programmed to use its unused split time.
If you program Preference Phase 1st (Pref 1) and Preference Phase 2nd (Pref
2), the unused split time will first be available to the Pref 1 subsequent phase to
use if it maxed out in the last cycle. If Pref 1 Subsequent phase does not qualify,
the unused split time will be available to the Pref 2 subsequence phase. If Pref 1/
Pref 2 subsequent phases do not need the Initial unused split time, the unused
split time is added to the coordinated phase. The allocation of the unused split
time does not affect the sum of the split time used for each ring.
Example: Phase sequence is
2 1|3 4
6 5|7 8
Phase 2, 6 are coordinated phases. Initial Phase 1 has Preference Phase 1st as
Phase 4. If there is any unused split time from Initial Phase 1, and Subsequent
Phase 4 is available and maxed out during last cycle, then the unused time could
be used by Subsequent Phase 4 if it has the demand.

Ring Displacement From Ring 1
Use the scrubber to select the displacement (Offset) from Ring Offset One that
independent ring coordinated phase(s) will start.
0 to (Cycle time minus 1) seconds or 0-99% is the displacement Ring 1 for
Rings 2, 3 and 4.
Cycle time of 255 seconds or 100-255% results in no displacement.
The Offset for the rings are as follows:
• Ring 1 offset is the programmed offset.
• Ring 2 offset is the programmed offset plus the Ring 1-2 Offset.
• Ring 3 offset is the programmed offset plus the Ring 1-3 Offset.
• Ring 4 offset is the programmed offset plus the Ring 1-4 Offset.
Note: When two or more rings (1-4) have a barrier in common, the higher
numbered ring is forced to use the value of the lower numbered ring.
Example: Rings 1 and 3 have a barrier in common. The Ring Displacement 1-3
will be ignored and Ring 3 will use the offset of Ring 1.
