2. LCU NEMA model LCUN35G
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
2.1 “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.
2.2 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.
2.2.1 GPS
If the LCU NEMA contains a GPS component, the coordinates are obtained without installer involvement.
