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.

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
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.
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 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.

The 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.

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.

Installation
The 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 side
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.
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 side
All cables on secondary side should preferably be
shielded, with the shield connected to GND (pin5 for
the A-Bus).
