System Features®
The Horizon Signal system is capable of three modes of operation:
• Radio - Wireless communication between all controllers in the system.
• Cable - Wired communication between all controllers in the system.
• Quartz - Synchronized timing of all controllers in the system via quartz clocks. Controllers do not communicate
in this mode.
• A system can also utilize a mixture of radio and cable connections.
Systems can include up to 8 controllers or 7 phases of traic. Multiple controllers can be grouped into the same traic
phase.
The Controller
The controller is where the currently running program is stored. It is the device that coordinates all of the signals within
a system and ensures that they all operate properly. The controller can also detect errors on a signal or in a group. Each
phase of traic has at least one controller.
The controller is programmed using the micro-terminal. The micro-terminal plugs into the face of the controller via the
7-pin recept next to the power toggle switch.

The Micro-Terminal
The micro-terminal acts as a mechanism to enter programming data into the signal controllers. It also coordinates and
synchronizes the signal controllers within a signal system. Any multi-phase micro-terminal can be used to program
any multi-phase controller. The micro-terminal gets plugged into the face of the Controller via the Hirschmann plug
located next to the Power toggle switch.

The Home Screen
The home screen is where the user can view current system status, as well as monitor real-time operation of the entire signal
system. The number in the top-le corner identies the light your micro-terminal is plugged into. This light also has a cursor
below its visual indication in the active lights eld. By pressing “R” the user can move this cursor to identify battery voltage
or errors on other lights in the system.

Assigning Controller Identities
Before a program can be entered, all of the controllers in the system must be communicating. To accomplish this, each
controller is given an identity. Additionally, when using wireless communication, each radio must be assigned a “Master” or
“Slave” designation as well as an operating channel. Cable can also be used to link the signals together.
1. To begin, power the Controller on with the Micro-Terminal plugged in. You will be
presented with the initial startup screen which displays the soware version number.
2. The micro-terminal will then ask you, “New System?” By answering “No,” no changes
are made to the controller’s identity. Any time you wish to change an identity or add or
remove signals, you must use this option. In this case, answer “Yes.”
3. The screen that follows is where you assign the controller’s identity. The arrow identies
which option you currently have selected. First, set the communication type (Radio,
Cable, or Quartz timing). Press E to advance the cursor to the next option. The rst
number represents the identity of the controller you are currently plugged into. The
second number represents the total number of controllers in the entire system. Each
of these numbers can be changed depending on your specic setup. For a typical work
zone, you will have 2 signals (controllers). Controller #1 gets assigned as 1/2. Controller
#2 gets assigned as 2/2.
4. Repeat this process on each controller in your system. Remember that each controller
must have a dierent identity (rst number) but the same total quantity (second
number). These settings only have to be congured once, unless you are changing the
number of lights in your system!

Addressing Radios
Signal systems using radio communication require one Master radio which can relay program information to all other re-
mote radios of the system. There are 14 channels that can be used for communication.
1. To program your radio, start from the Home Screen. Press and hold the “R” button
until the soware version screen appears. Immediately press the “+” button before this
screen disappears. (If you miss the rst time, just hold “R” again.)
2. First you must choose whether this radio is a Master or a Slave. Each system must have
ONE Master. All other radios must be Slave radios.
3. Next, set the desired radio channel. Every radio in the system uses the same channel.
4. Finally, the screen will ask you “Transmit OK?” Once this screen appears, you must
press the “Reset/Cong” button located on the side of the radio unit (see next page),
to allow the radio to accept the new conguration. The red LED labeled “M2” should
illuminate when the button is pressed to conrm that the radio can be recongured.
5. Continually press the E button on your micro-terminal to repeatedly transmit the new
settings to the radio unit. Once the “M2” light goes out, press “R” until you are returned
to your home screen. As each radio is properly addressed, you should see the signals
appear on the top of your home screen.
Note: The micro-terminal cannot read a radio’s existing address. It can only SEND to the radio. When changing an address,
write the number on the sticker located on the side of the radio for future reference.

Basic Programming
Programs can be edited or changed at any time while the Horizon Signal system is running. By plugging in the micro-
terminal the user can create new programs without any eect on the current program. A new program that is created
will be loaded during the next available Red Clearance time, and will be undetectable by motorists.
1. From the Home Screen press “+” to access the System Menu. The rst option is System
Programming. Press E to begin.
2. The micro-terminal has several program templates pre-built for you. These simple
templates represent the most common types of workzones. To pick the correct
template, you will need to know how many phases of traic will be in your workzone
and how many Horizon controllers your system has. When necessary. basic programs
will automatically group Lights numerically based on their controller identities.
3. The speed of the workzone gets entered rst.
4. The distance of the workzone gets entered next. The microterminal will use these values
to calculate a recommended Red clearance time.
5. The calculated Red time will be displayed based on the information already entered.
This time can still be adjusted by using the + and -- buttons.
6. Number of Programs refers to the amount of dierent timing sequences this system will
run for this setup. This number is typically 1, unless day phasing is desired.
7. You will now be asked to enter Green times for Group #1 (C1 in the upper-right corner).
The rst number on the screen is the base green. This is the minimum amount of green
time a given phase will allow without detection. The second number is the extension
time. The extension will only be applied if the system is using some form of vehicle
detection. If you are not using detection, the extension will be ignored.
8. If you would like the signals in this group to remain Red until there is a vehicle detection,
set Rest in Red to “Yes.” Otherwise, set it to “No” to allow the signals to cycle normally.
9. Next, set the green times for Group #2 (C2 in the upper-right corner). These times do not
have to be the same as the times for Group #1.
10. The Rest in Red option for Group #2 gets set next.
11. Number Times asks how many times per day the controller will change programs.
The default setting is 0. This option is only used when you would like to run multiple
programs throughout the course of a day or week, such as morning and evening rush
hour programs.
12. Review the information you provided to the micro-terminal by viewing the summary
screen at the end of the program. The type of program will be displayed at the top of
the screen, followed by # of programs, # of groups, and total # of lights. When you are
sure that the information is correct, press E to load the program.
13. The micro-terminal will show the progress of the radio programming (or cable if not in
radio mode). When the counter reaches 100%, the micro-terminal will go back to the
home screen and the program will begin to run.

Special Programming
Special Programs allow for more control than basic programs, allowing the user to adjust all settings and create custom
signal groups for more advanced aplications.
1. From the Home Screen press “+” to access the System Menu. The rst option is Sys-
tem Programming. Press “E” to begin.
2. Use the “+” key to scroll through the Programming menu until you see “Special.”
Press “E.”
3. You must rst dene the number of groups (phases of traic) that your program will
have. There can be multiple controllers per group.
4. Aer the total number of groups has been entered, the micro-terminal will ask you
how many lights (controllers) are in each group, starting with Group 1.
5. Traic Gap refers to the amount of time the system will hold a detection in memory
aer that detection occurs. When the nal car passes through the light, the green will
be extended this amount of time to allow for more cars to pass through.
6. Yellow time can be set for each individual phase from 0-15 seconds. The default
value is 4 seconds.
7. The Error setting is the mode that the phase will enter in the event of a fault. Each
phase can have its own Error mode.
8. The Flash setting is the mode that the phase will enter if the user manually enters
Flash Mode. (This can be done by pressing E from the home screen.) This will also
be the startup mode when the signal is rst powered on.
9. Items 4-8 will now be repeated for each remaining group in your system. Again,
values and settings do not have to remain the same for every group.
10. Enter the distance between each of the lights in your system.
11. Enter the average speed of the slowest anticipated vehicle travelling through your
work zone.
12. The micro-terminal will display the calculated red time. Unlike simple programming,
Special programming shows you the red time in both directions (C1 to C2 and C2 to
C1). All times can be adjusted by using the “+” and “--” keys.
13. Number of Programs refers to the amount of dierent timing sequences this system
will run for this setup. This number is typically 1, unless day phasing is desired.
14. Green times for Group 1 can now be entered. The rst number shown is the base,
or minimum green. The second number is the extension. Base green + extension =
maximum green.

15. If you would like this signal to remain Red until there is a vehicle detection, set Rest
in Red to “Yes.” Otherwise, set it to “No” to allow the signal to cycle normally.
16. Sensor Priority gives that controller priority in the event of multiple detections.
Other signals will get green extensions dropped in favor of signals with priority.
17. Steps 14-16 will be repeated for Group #2. Enter Green time and extension, as well as
the Rest in Red option and Sensor Priority for each remaining group.
18. Number Times asks how many times per day the controller will change programs.
The default setting is 0. This option is only used when you would like to run multiple
programs throughout the course of a day or week, such as morning and evening
rush hour programs.
19. The Max Red Parameter allows the controller to force a cycle on any phase that has
rested in Red for this amount of time. This is only necessary when Rest in Red mode
is enabled on any signals.
20. The Min Green Parameter dictates the shortest allowable green time for all phases.
Useful when operating in Manual Mode.
21. The Min Red Parameter dictates the shortest allowable red time for all phases.
Usefull for Rest in Red scenarios where the same phase may be called repeatedly.
22. The Flash Green Parameter adds a period of ashing green during the Yellow Interval.
Be aware that any Flash Green time will be subtracted from the programmed Yellow
Time. Example: 10 second yellow time with 5 second ash green time = 5 seconds
ash green and 5 seconds yellow.
23. Review the information you provided to the micro-terminal by viewing the summary
screen at the end of the program. The type of program will be displayed at the top
of the screen, followed by # of programs, # of groups, and total # of lights. When you
are sure that the information is correct, press E to load the program.
24. The micro-terminal will show the progress of the radio programming (or cable if not
in radio mode). When the counter reaches 100%, the micro-terminal will go back to
the home screen.
25. “Program loading” will appear at the bottom of the screen. A new program will not
load until the next red clearance interval is reached, at which point the program will
load seamlessly with no ash or dark signals between programs.

Saving a Program in Memory
The memory storage function of the micro-terminal is accessible by pressing “+” from the home screen 2 times. Using the
memory function allows the user to save up to 10 programs that can be loaded or edited for later use. Memory programs
can be given unique names to identify them. This name will be shown on the home screen when the program is loaded.
To create and store a program, or edit an existing program in memory:
1. From the Home Screen press “+” to access the System Menu. Press “+” one more
time to scroll to the memory function and press “E” to enter.
2. There are 10 memory slots in this section of the micro-terminal. By using the “+”
and “-” buttons to scroll through, you can view the programs stored in each slot.
Find one that is empty and press “E.”
3. Using the “+” and “-” buttons, scroll through the alphabet to give your program a
unique name that will help you identify it later. Include a blank space at the end to
enter the program name. From this point the micro-terminal will ask you to create
a program as normal. Follow the prompts and enter the program data.
4. When you reach the end of the program, you swill see a screen conrming that your
program has been stored into memory. Programs will stored in memory are not
immediately loaded and run.
5. To load the program, or any other program stored in memory, choose it from the
memory list by pressing “E.” You will have three options to choose from by using
the “+” button:
Loads and runs the chosen program.
Allows the user to edit or review the chosen program.
Deletes the chosen program, emptying that memory slot.
System Clock
The system clock is used to synchronize quartz systems and tag all entries in the data log. It is also used in programs that
utilize dayphasing. By pressing “E” the user can set the clock to local time. The “+” and “-” buttons are used to change
values, and “E” is used to enter and move forward.

System Mode
The mode function of the micro-terminal is used to change between signal operation modes. This menu can also be
accessed by simply pressing “E” from the home screen. Once inside this menu, the user can scroll through the various
operational modes by using the “+” and “-” buttons and pressing “E” to select and enter that mode. When a mode is
selected, it will not change until the next programmed red clearance interval has expired.
Runs the currently loaded program.
Signals are operated manually via the micro-terminal. User cannot override red
clearance times.
Signals will operate in the Flash mode selected in the System. Options menu (Red
Flash or Yellow Flash). SPECIAL programs allow for override of this setting within
the program.
Signal indications will go dark and no longer be displayed. Program is not deleted.
All signals will go to a solid red indication and remain in this state until the mode
is changed.
All signals will go to a ashing red indication and remain in this state until the
mode is changed.
All signals will go to a ashing yellow indication and remain in this state until the
mode is changed.
The current program is stopped and erased. Signals will go to Flash mode. A new
program must be created or loaded from memory before signals can operate in
Automatic mode again.

System Options
When you are setting up a system for the rst time, it is a good idea to check the controller’s settings. You can access these
options by pressing “+” from the Home Screen and scanning through the SYSTEM menu until you see “System Options.”
Press “E” to enter the menu. Each of these settings refers to the specic controller which you are plugged into.
You will rst be prompted to enter a password. The default Horizon password is
“abcd.” Use the + button to scroll through the alphabet. To enter the password, leave
a blank space at the end and press E.
• Language sets the micro-terminal language. English, French and Spanish are available.
• Signal Sequence sets units of distance and speed to the appropriate country (USA or
Canada - CDN).
• Change clear time manual allows the user to manually handle the system with no
regard for programmed Red clearance time. When the option is disabled (set to “No”), Red
clearance time is automatically added between opposing greens when manually handling.
• Timeout refers to the amount of time the controller will tolerate a break in radio
communication. Note that the higher this number is, the longer it will take the system to fail
in the event of a communication loss. The default Horizon value is 5.0 seconds
• Quartz Substitution is an option that allows the system to continue operating once radio
communication has been lost. If communication is broken for longer than the Timeout
value, the controller can revert to Quartz mode to continue operating. By default, this
option is set to “No.” There are four other options to choose from in the event of lost
communication:
• Flash Red - A ashing red indication will be shown in place of green during green time
• Flash Yellow - A ashing yellow indication will be shown in place of green during green
time.
• O - Lamps will go dark during green time.
• Green - Green indication will appear as normal. Green time will equal the programmed
minimum green PLUS half of the extension time.
When the system is running in Quartz Substitution mode, extended green times will be
disabled due to the loss of communication. All green times will equal the base green time
plus half the extension time. If communication is reestablished, the program will run as
normal. Once activated, the system will run a minimum of 2 cycles before returning to radio
mode (once communication has ben re-established).
• Error Signal is the mode that this particular controller will enter in the even of a failure
when running a pre-dened program. Flash Red, Flash Yellow, Solid Red, and Lamp O are
available. Flash Red is the default setting.
• Flash Signal is the indication that will be displayed when the user manually activates
Flash Mode via the micro-terminal when running a pre-dened program. Flash Yellow is
the default. NOTE: Using SPECIAL programming, each phase can be set to a dierent Flash
Mode to allow main traic to ow while side streets must stop.
• Horn Output is not used. It gets set to Error.
Finally, you will be asked to conrm the password one nal time.
NOTE: If any of these settings are changed, they will not take eect until a new program is loaded.
