ST Engineering Telematics Wireless Ltd 1. 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.
ST Engineering Telematics Wireless Ltd 2. 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.
ST Engineering Telematics Wireless Ltd 2.2.2 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. 3. Safety Instructions Only qualified personnel should perform the installation. Follow all local electrical codes during installation.

ST Engineering Telematics Wireless Ltd 8. Installation Overview Important Note: Read the entire Installation Guide before beginning the installation process. It is assumed that the customer has installed the following: NEMA ANSI C136.10-2010 and C136.41-2013 compliant receptacle in the luminaire cover. Required customer-supplied voltage and current surge protection. Preparing for installation is different depending on which, if any, GPS coordinate obtaining components are in the LCU NEMA.
ST Engineering Telematics Wireless Ltd 8.2 Installation without the GPS components 8.2.1 CSV file During the installation, the installer needs to obtain and record the following required commissioning information in a CSV file: Unit ID/serial number of the installed LCU NEMA Pole number (if any) GPS coordinates obtained using a handheld GPS device. See 8.2.2. Options for Obtaining GPS Coordinates.
ST Engineering Telematics Wireless Ltd ◦ ◦ 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. 9. 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.
ST Engineering Telematics Wireless Ltd ◦ ◦ ◦ ◦ ◦ 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).
ST Engineering Telematics Wireless Ltd 10. Post-Installation Commissioning Commissioning is activated by the CMS Administrator after the LCUs and their respective DCUs are installed. Instructions for the CMS Administrator are available in the LCU Commissioning Guide. 11.
