Segment Control Unit Product guide LCN7700 The Segment Control Unit is central processing unit (CPU) in the cabinet system. Equipped with a powerful ARM Cortex A5 (550MHz) processor and a Linux kernel. Commonly used interfaces for Energymeter, load current and leakage measurement, relays for contactor mains switching are integrated into the Segment Control Unit for ease of wiring and compactness. Direct communication between the optional modules takes place by means of an A-Bus interface, which is based on the industrially proven RS485 technology. LCN7700 Data are either delivered to the server immediately or stored locally in the built-in flash or external SD card memory of the Segment Control Unit until scheduled delivery. Software and configurations are updated remotely from the server and stored on the Segment Control Unit enabling it to autonomously execute tasks, e.g. turn the streetlight on/off or collect meter readings based on the configurations set up by the user. Voltage values on all three phases of the main supply are monitored by the Segment Control Unit. If the module is installed together with a Battery module, the Segment Control Unit will be supplied with backup power via the A-Bus in the event of power failure. This enables the Segment Control Unit to store data and send a main power failure alarm to the central server before it shuts down safely. In general, the Philips Segment Control Unit can be used for remote light management in diverse outdoor Lighting applications. Dimensional drawing 86 mm (3.3 in) The Segment Control Unit serves as a WAN communications and data concentrator module. Two-way communication with the central server takes place via Ethernet, GPRS (3G/2G) or SMS. The module has the ability to automatically switch between different available communications carriers in order to provide stable and reliable communication. 58 mm (2.2 in) 192 mm (7.5 in) Philips quality Lifetime: 70000 Hrs @ 10% failure rate. For more detailed information see the specific module manuals & guides. Applications The Segment Control Unit is a power grid monitoring and group lighting control device. It is designed to be installed inside an IP65 rating outdoor street cabinet. This control unit is designed as a local controller for group light controls as in road and street, expressway, premises/campus area lighting, public parks or in tunnel lighting applications. For remote connectivity, 2G/3G network can be used or Ethernet connectivity in case the cabinet is located indoors. The accurate current measurement can help to detect power thefts when the current value goes beyond a threshold limit defined. The inbuilt GPS locater helps to detect the location of the installed controller remotely to enable ease of commissioning. The DALI interface gives opportunity to control other DALI enabled devices like a group of luminaires in a high mast pole in airport or port applications with dimming capability. The wide input power supply voltage range from 120-277V makes the controller to be used in wide geographical locations. The use of an external surge protection module is highly recommended to protect the Segment Control Unit from surges.

Primary Power (L1, L2, L3, , N) Three mains rated phase (line) inputs: L1, L2 and L3 One mains rated alarm monitor input: One mains neutral input: N The Segment Control Unit can be mains powered by one, two, or three phases plus neutral. When powered by multiple phases, the Segment Control Unit is able to detect phase faults on the mains power supply. If a fault occurs on one or two phases, the Segment Control Unit will still be powered by the remaining phase(s). In this case, the Segment Control Unit will send an alarm to the central server. The alarm monitor ( ) is a mains rated input (related to mains Neutral (N)) for cabinet door monitoring. Secondary USB 2x USB 2.0 host port for additional devices Inputs 2x Analog 1x Digital Ethernet Product Guide - LCN7700 Low voltage measurement inputs analog input 1 and analog input 2 (positive voltage w.r.t. GND). Low voltage input digital input (positive voltage w.r.t. GND). RJ-45 connector, 100/10 Mbps, half & full duplex, functional insulated from the secondary connections. Reliability & Maintainability Software upgrade/ installation Multi-layer system The software on the Segment Control Unit can be updated remotely from the central server. New software is transferred without interrupting the normal functionality of the Segment Control Unit. When the software has been transferred, the integrity of the software is checked and the software is installed. Connections on the secondary side All cables on secondary side should preferably be shielded, with the shield connected to GND (pin5 for the A-Bus). EU directives Use shielded twisted pair (2x2) cable. The Segment Control Unit can be connected to any client module e.g. AmpLight RS485, AmpLight Switch. Double connections on the A-Bus makes daisychaining of the signals easy. For detailed information, see wiring diagrams. Various internal processes ensure that the system is up and running at all times. A-Bus cable cable length < 3 m In case a process has failed, it is restarted without disturbing other processes. RS485 cable length < 3 m Analog/Digital Input cable length < 3 m Current Sensing Input cable length < 3 m Keep wiring short from the mains circuit breaker towards the mains power input. When using a surge protection module, the wires between the surge protection module and the Segment Control Unit may not exceed 0.15 m. Philips recommends for outdoor applications to use a surge protection module. DALI cable length < 10 m USB cable length < 3 m At least one GROUND connection needs to be connected to Earth or screwed GPS or 2G/3G antenna is connected and installed on cabinet. RS232 cable length < 3 m Ethernet cable length < 3 m Mains Input cable length < 1.5 m System health Self-test A built-in self-test is performed after power-up.
