Positioning & Setup Upon arriving at the job site, begin by completing the following tasks: Determine location and position of lights as per job plans. See diagram below for an example of a typical work zone. Light #2 Light #1 Have flaggers control traffic on both ends of the work zone.
Page 11
Before deploying the mast arm, determine if the signal heads must be rotated. If so, • Safely step up on to the trailer using the step on the fender. • Use 9/16” wrenches to loosen the counter bolt on the light bracket. Loosen and remove the second bolt using the same wrenches.
Page 12
• Safely step down off fender using front step on trailer fender Unfold the portion of the mast that has the traffic light • When unfolding the mast arm out into the roadway you must stop traffic! 10. Unfold the center portion of the mast, as seen above. 11.
Page 13
13. Flip the workzone indicator light to the operating position. • This light points back into the work zone as an indication of the current signal indication. If this light is illuminated, that signal is currently in red. If the light is dark, the signal is currently green or yellow. 14.
• Insert safety locking pin and clip that you removed from the rear support post • Install pad lock to lock pin in place so no unauthorized person can lower mast arm 15. Transfer solar panels to operating position by removing the pins and sliding them outward. Repeat these steps for the unit at the other end of the job site.

The Controller Cabinet The controller cabinet houses the majority of the Horizon Signal components, including the Multi-Phase Controller, Data Radio, Circuit Board, ProStar Solar Charge Controller, Hydraulic Control Switch, and Remote Monitoring System unit. 1. Multi-Phase Controller - Works in conjunction with other controllers in the signal system to operate signal timing and sequencing.
System Features 1. 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.
Page 21
If the controller is turned on without a micro-terminal plugged in, it will automatically load its most recent program. This means that if the signals are shut off at night, the program will still be ready to run when they are powered on the next morning. No reprogramming is necessary unless there has been a change to the work zone (speed or distance) or timing sequence.
SRM6220 Data Radio Reset / Power Config Comm. • Reset/Config button - used to change radio designations and communication channel • RF Indications: P - indicates the radio has power. L - flashes rapidly when the radio is communicating as a Master. Remains solid when communicating as a Slave.
Morningstar ProStar 30 The ProStar 30 monitors and regulates solar charging of the batteries in your system. The display cycles through 3 screens, along with the 3 red LEDs to the right of the display. The first screen and LED will display the battery voltage on that trailer.
Remote Monitoring System (RMS) The Remote Monitoring System utilizes GPS, internet, and cell phone technology to send text messages to users and to generate internet reports for Horizon Signal systems. Internet reports track information on location, operating hours, battery voltage, and fault/run. The RMS system allows authorized users to access a satellite view of signal location via a password-protected webpage.
Page 25
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 (see next page for more information).
Micro-Terminal Screens The Micro-Terminal screen illuminates when plugged into the controller with power on. The screen pro- vides a visual display of the program data as well as real-time monitoring of a running program. Here is a brief overview of some of the commonly used screens. Software Version screen.
Getting Started 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. Assigning Controller Identities To begin, plug in your micro-terminal and power the system on.
Programming: An Introduction The home screen is where the user can view current system status, as well as monitor real-time operation of the entire signal system. Active Lights Light # Battery Voltage 1 :: :: 12,6v R Program 1 Counter Connection Type Program Name/ Mode/Errors...
Programming There are two main types of programs - work zone programs and intersection programs. Work zone programs are programs where all groups go green one after the other. Each group can work with fixed green times, green time extensions or resting in red.
Page 30
PROGRAM 1 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 Rest in red No cycle normally.
Simple Program Templates The micro-terminal allows the user to choose from several simple program templates to make programming easier. In order to choose the correct template for your job site, you must first know the number of traffic phases and number of controllers in your system.
Page 32
2-Phase 4-Controller This setup is very similar to a 2-Phase 2-Controller work zone. In this case, two controllers are operating as a single phase (group). This is the typical program used for SQ2 carts. Groups are color- ® coded below for easy identification. C2/L3 C1/L1 C2/L4...
Page 33
3-Phase 3-Controller This setup is most often used for T-intersections, or work zones with a driveway. In setups with more than 2 phases, you must determine the distance between all lights (C1-C2, C1-C3, and C2-C3).

4-Phase 8-Controller This setup is very similar to the 4-Phase 4-Controller setup. In this case, two controllers operate each phase rather than just one. Each direction of traffic operates as its own phase. Note that this is the maximum number of controllers that may operate in one system. C2/L3 C2/L4 C4/L7...
Page 39
2-Phase 8-Controller This setup is very similar to the 2-Phase 4-Controller setup. In this case, two controllers operate each phase rather than just one. Northbound and Southbound traffic may operate concurrently, and Eastbound and Westbound traffic can operate concurrently. Note that this is the maximum number of controllers that may operate in one system.
Special Programming Special Programs allow for more control in the creation of a program. The user has complete control over all of the options when creating a Special program. This type of programming also allows the user to create signal systems that do not fit into any of the pre-built template programs already in the micro-terminal (2-Phase 2-Controller, 4-Phase 4-Controller, etc).

Conflict Monitor / System Faults The Horizon Signal controller has a built-in malfunction management unit, or conflict monitor. This unit monitors system operation in real time to ensure proper and safe operation. In the event that an error occurs, the conflict monitor will force the system into the programmed fault mode. Possible faults include: loss of communication in radio or cable mode, burned-out lamps, crossed- indications (multiple lamps on at once), and improper battery voltage (low or high).
Wireless Interface System The Wireless Interface Module allows a Horizon Portable Traffic Signal to be connected to and controlled by any NEMA compliant street corner controller. This system allows for quick and easy temporary signal substitution of a permanent signal in the event of a knockdown, signal relocation, or traffic pattern reconfiguration. The entire system can be setup and operational in 30 minutes.
Wireless Interface System Setup The Cabinet Interface Module (above) is the unit that gets installed on the existing street corner traffic signal controller cabinet. It utilizes wireless radio communication to trans- mit and receive lamp loads on the temporary signal. 1.
