Product guideLCN7700The 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. Segment Control Unit
2Product Guide - LCN7700 LCN7700The 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 dierent available communications carriers in order to provide stable and reliable communication. Data are either delivered to the server immediately or stored locally in the built-in ash or external SD card memory of the Segment Control Unit until scheduled delivery. Software and congurations 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/o or collect meter readings based on the congurations 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.For more detailed information see the specic module manuals & guides.ApplicationsThe 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 dened. 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.In general, the Philips Segment Control Unit can be used for remote light management in diverse outdoor Lighting applications..Dimensional drawingPhilips qualityLifetime: 70000 Hrs @ 10% failure rate.192 mm (7.5 in)58 mm(2.2 in)86 mm (3.3 in)
Product Guide - LCN7700 3The Ethernet connection is, in addition to this, functionally insulated with respect to the secondary connections. See for detailed information the technical specication section.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.

4Product Guide - LCN7700 Reliability & Maintainability Software upgrade/installation 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.Multi-layer system Various internal processes ensure that the system is up and running at all times.System health In case a process has failed, it is restarted without disturbing other processes.Self-test A built-in self-test is performed after power-up.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 daisy-chaining of the signals easy. For detailed information, see wiring diagrams.A-Bus cable cable length < 3 mRS485 cable length < 3 mAnalog/Digital Input cable length < 3 mCurrent Sensing Input cable length < 3 mDALI cable length < 10 mUSB cable length < 3 mRS232 cable length < 3 mEthernet cable length < 3 mMains Input cable length < 1.5 mInstallationThe Segment Control Unit should be protected from dust and water, preferably by enclosing the system in a metal IP class 65 (NEMA type 4) outdoor cabinet. Connections on the primary sideKeep 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.At least one GROUND connection needs to be connected to Earth or screwed GPS or 2G/3G antenna is connected and installed on cabinet.Connections on the secondary sideAll cables on secondary side should preferably be shielded, with the shield connected to GND (pin5 for the A-Bus).
