ST Engineering LCUN35HGX Light Control Unit

Street Lighting Control

Street lighting is one of the most essential services provided by municipalities and the lighting’s electricity bill is one of their major expenses. The Telematics Wireless’ T-Light™ networks enable municipalities and utilities to control and manage street light operations with operational efficiency and cost effectiveness.

T-Light Galaxy Network – a wide area network utilizing a single Base Station that covers an area of up to 20 km radius and monitoring directly thousands of luminaries.

The Galaxy network comprises of three major elements:

LCU – Light Control Unit / Node , installed on top or inside the luminaire (external “NEMA” or internal configuration), enabling the transmission of information, and the reception of control commands for the luminaire’s LED fixtures. Includes built-in energy metering and possesses auto-commissioning functionality.

DCU – Data Communication Unit / Base station – The information from and to the LCU is routed via the DCU and via the Internet, using GPRS/3G or Ethernet connections directly to the BackOffice application.

CMS – Control and Management System – is a web-enabled BackOffice application, accessible at any location in the world simply by using a standard browser, such as Internet Explorer or Google Chrome. CMS usually contains a database of static and dynamic LCU information: ambient light values, lighting and dimming schedules, power usage, status, etc.

LCU NEMA model LCUN35GX

The LCU NEMA is installed on top of a luminaire cover into a standard NEMA receptacle.

Standard Features

• Light sensor – Operates as a photocell with the integrated microcontroller and is used as a backup light control in the event of microcontroller failure.
• Energy meter – Continuous measurement collection and aggregation with 1% accuracy.
• Integrated RF antenna.
• Over the air firmware updates.
• Each unit is configurable as a repeater, resulting in one additional ‘hop’ from the DCU.
• Real Time Clock
• Network data is protected by AES 128 encryption.
• Relay Control for LED driver/ballast power.
• Uses licensed frequency.
• Built in GPS receiver for auto-commissioning
• “Auto Detection and Verification” Software

Auto Detection and Verification” Software

The LCU NEMA includes the Telematics “Auto Detection and Verification” software that automatically detects and stores the ballast type (1-10V or DALI) in the LCU. The ballast type is then retrieved during the commissioning process, thereby eliminating the need to enter it manually into the CMS (auto detection process also occur each time the power turns on from off state)
Note : By default, the “Auto Detection and Verification” procedure works during the day and the night. To configure the procedure to work only during daylight hours, contact Telematics support.

Options for Commissioning

Commissioning is the last step in the installation process whereby each LCU is identified in the CMS. In order for the CMS to communicate with individual LCUs or groups of LCUs, the CMS must receive the GPS coordinates for each installed LCU. Installer activity during installation is partially dependent on whether the LCU NEMA is equipped with one of the commissioning-related components.

GPS

If the LCU NEMA contains a GPS component, the coordinates are obtained without installer involvement.

No Commissioning Components

The installer uses a customer-supplied GPS device to obtain the coordinates. The installer then manually records the LCU’s serial number, pole number if any, and coordinates in a comma-separated value (CSV) file.

Safety Instructions

• Only qualified personnel should perform the installation.
• Follow all local electrical codes during installation.
• Although it is not necessary to disconnect power to the pole during installation, one should always be aware of possible exposure to electrical elements.
• When working from heights, it is important to follow standard safety precautions to avoid any danger of potential injury.
• Use appropriate work tools.

Mandatory Customer-Supplied Equipment

System integrity for the LCU NEMA is ensured with the mandatory installation of customer-supplied voltage and current surge protection equipment.

Mandatory Voltage Surge Protection

Warning : To prevent damage due to power network voltage surges, it is mandatory that you also provide and install a surge protection device to protect the LCU and the luminaire driver.

Mandatory Current Surge Protection

Warning : To prevent damage due to power network current surges, it is mandatory that you also provide and install a 10 amp slow-blow fuse or a circuit breaker to protect the LCU and the luminaire driver.

2. Standing as close as possible to the pole, obtain the GPS coordinates for the pole using one of the options described in 8.2.2. Options for Obtaining GPS Coordinates.
3. Record the coordinates for the LCU NEMA in a CSV file.
4. Install the LCU NEMA. See 9. Installing the LCU NEMA.
5. Observe the ON/OFF light sequence that verifies the LCU installation. See 9.1 Observing the “Auto Detection and Verification” Procedure.
6. After each LCU NEMA installation, the installer has the following options for providing the
   commissioning information to the CMS Administrator:

• * Sending the required information of each LCU NEMA as it is installed to the CMS Administrator, by calling or messaging.

  • Updating the CSV file with the LCU serial number and coordinate values obtained during the installation.

Installing the LCU NEMA

1.  Align the LCU until the North Marking Arrow at the top cover will be in the same direction as the North Marking Arrow at the receptacle.
   Firmly insert the plug into the receptacle: Warning: Inserting the LCU NEMA prongs into the wrong sockets in the receptacle can
   damage the LCU NEMA

2. Twist the LCU clockwise until the LCU stops moving and is securely locked.

3. If the electrical power is not ON, turn ON the power to the pole and be ready to verify that the installation is correct. See 9.1. Observing the “Auto Detection and Verification” Procedure.

Observing the “Auto Detection and Verification” Procedure

To perform the “Auto Detection and Verification” procedure:

1. If the luminaire is not already under power, power ON the main power line connected to the
   luminaire.

2. The luminaire will turn ON (light on) immediately upon installation of the LCU to the powered luminaire or immediately upon connection of the power line.
   After initially turning ON, the luminaire will run the “Auto Detection and Verification” procedure which identifies the lamp driver type and executes the following light ON/OFF sequence:
   In case of dimming method 0 – 10:
   • After approximately 18 seconds of being ON, the luminaire will dim to about 50%, if dimming is supported.
   • After approximately 9 seconds, the luminaire will change to 5% if dimming is supported.
   • After approximately 10 seconds, the luminaire will return to 100%.
   • After approximately 8 seconds, the luminaire will turn OFF (light out).
   • After approximately 12 seconds, the luminaire will return to whatever operational state the
   internal photocell or CMS schedule determines.
   In case of dimming method dali:
   • After approximately 27 seconds of being ON, the luminaire will dim to about 50%, if dimming is supported.
   • After approximately 4 seconds, the luminaire will change to 5% if dimming is supported.
   • After approximately 10 seconds, the luminaire will return to 100%.
   • After approximately 6 seconds, the luminaire will turn OFF (light out).
   After approximately 12 seconds, the luminaire will return to whatever operational state the internal photocell or CMS schedule determines.

3. If the luminaire does not complete the verification procedure, follow the basic troubleshooting steps
   in 9.2. Troubleshooting:

4. If the luminaire successfully finished the “Auto Detection and Verification” procedure, the LCU
   physical installation is complete.

Note : Each time the main power to the pole is lost, the “Auto Detection and Verification” procedure is executed when power is restored.

Troubleshooting

If the “Auto Detection and Verification” procedure is not successful, troubleshoot as follows:

To troubleshoot a LCU NEMA installation:

1. Remove the LCU plug by twisting the plug counterclockwise.

2. Wait 15 seconds.

3. Reseat the LCU in the receptacle securely.
   As soon as the LCU is reseated, the “Auto Detection and Verification” procedure will start.

4. Observe the ON/OFF sequence.

5. If the “Auto Detection and Verification” procedure fails again, select and install a different LCU.

6.  If the verification procedure fails with a different LCU, verify the following:

   • The lamp driver and luminaire are working correctly.
   • The receptacle is installed correctly.
     For additional troubleshooting steps, contact Telematics support. See 11. Contact Details.
