Operation Modes

Automatic Mode (Fixed timer)

• In this mode, cycle of RED, YELLOW and GREEN lights for both approaches is successively activated. There are user defined time durations for all lights.

Light sequence is:

• Green light is followed by yellow. Yellow light is followed by red. Red light is followed by green light.
• Red light duration is the same as green light on another approach + clearance time. Minimal red time is 5 sec. Clearance time is needed for vehicles to pass from one side to another.
• Clearance time is depended on two variable parameters: vehicle speed and distance. This will be different for every site. User will need to make test runs of the system for every site in order to determine optimal clearance time.
• In control tablet application there is automatic recommendation for clearance time. User need to enter parameters: distance between two lights and average vehicle speed.
• Calculated value for clearance time is then multiplied by two and this is recommended value for clearance time.
• Minimal clearance time is 5sec.
• Clearance time is added to red light time, so we have minimum red light for 10sec in any configuration. Green light is set by user, but it is minimal 5sec.

Vehicle Activated option

• Vehicle activation works with Automatic and Manual modes only.
• When there is a green light on one approach and if vehicle is detected in oncoming direction, green time will be ex- tended while vehicle is detected, but not longer than maximal green extended time which is defined by user.
• If vehicle is still detected but extended time has run out, portable light system starts with pass closing procedure and opens another approach.

Manual Mode

• Manual mode could be activated by Remote control and by Tablet Traffic Light console.
• In manual mode one cycle of automatic light sequence can be started. Manual mode let vehicles from both approaches to pass successively and then system turns on red lights.
• Lighting periods are the same for both Manual and Automatic mode.

All Red Mode to Stop Traffic

• This mode stops the traffic on site. Red light is activated on both approaches.

Flashing Yellow Mode

• This mode activates yellow lanterns flashing.
• This mode could be user choice or is automatically started when any hazardous situation occurred. For example, if red lamp fails.

Off Mode

Lights go off after a predefined light sequence is run out. Every changing of operation mode activates a predefined light sequence on both approaches:

• Yellow lights flashing for 5 sec
• Yellow lights steady for 5sec
• Red lights steady for 10sec0

Controlling the System

• System could be controlled directly over interface on Master unit, remotely via wireless remote control or via tablet Traffic Light application.
• System consists of two signal lights (red, yellow and green lamp), supplied with solar panels and batteries, vehicle detector, remote control and tablet with Traffic Light Console on it.
• There is a master unit and slave unit.
• Master and slave units are communicating via radio communication at 2,4GHz. Remote control is communicating with the master via radio communication at 2,4GHz.

Installation

• Only qualified and authorized staff shall do installation, maintenance and service work.
• Use proper tools for connection and maintenance of device.
• When mounting the sign on the carrier construction make sure to pro- vide a stable carrier construction.

LED signs must be installed onto a structure designed to withstand wind load, seismic events, weight load of ice in wintertime, or any other live load the structure might bear. The structure must comply with all national and local codes. Because every sign installation is unique, there is no single procedure for mounting the signs. Here is explained installation on a pole as this is most common installation.

Electrical Installation

• Carefully read the instructions for installation before switching on the device.
• While closing the front door it is necessary to take care on tight fitting.

Sign is powered from 12VDC battery. Battery is charged from solar power via solar charger.

Maintenance

Cleaning

For good visibility of the Traffic Light regular cleaning of front plate is necessary. The frequency of cleaning is de-pendent from the pollution of the environment in which the sign is used. We suggest cleaning of the front plate with warm water (temperature around 40 °C) and soft brush. If necessary, a neutral detergent can be added to warm water. In case that this is not sufficient, we advise use of cleaning alcohol. High-pressure cleaners may be used with a maximum working pressure of 80 Bar at a distance of 150 cm. It is not allowed to direct the jet of water directly onto rubber sealing or ventilation openings.

• The device must not be cleaned with aggressive detergents or solvents!
• Use only original spare parts recommended by the manufacturer of the TRS for replacement.
• When replacing spare parts device must be disconnected from power supply!
• Before starting any service try to connect to the sign, download “All Data” tables into excel file and save it. Data downloaded from the sign (LED error table, temperature table, event table), can help to find the cause of the problem and to prevent the same problem happen again!
• Explain any non-trivial problem shortly and make few pictures of the device. Send the explanation to the manufacturer or supplier, along with the pictures, serial number of the device and “All Data” tables downloaded from the sign.
• Carefully read the instructions for installation before switching on the device.
• While closing the front door it is necessary to take care on tight fitting.

Service is performed on the level of parts replacement. Part replacement is usually done in following steps:

• Switch OFF the main power supply. Open the sign.
• Check there are no phase voltages on the terminals. Remove the mechanical parts and connectors.
• Replace the faulty module.
• Close the sign.
• Switch ON the main power supply.

In order to open and close the sign use locker key

• To disassemble faulty module from the board, unscrew nuts and remove star washers.

During the service, special measures of ESD protection must be taken. Recommended regulations of EN 61340-5-1 and EN 61340-5-2 “Protection of electronic devices from electrostatic phenomena” should be applied

• Do not touch any of electronic parts inside the device without proper ESD protection.
• Use antistatic wrist straps to ground personal to common ground point.
• Use antistatic gloves.
• Use only ESD packaging for transport.
