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.

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.

Functional specifications
The Ethernet connection is, in addition to this,
functionally insulated with respect to the secondary
connections. See for detailed information the
technical specification section.
GSM/GPRS
SMA connector for external
GSM antenna. GSM850,
E-GSM900, GSM1800
(DCS1800), GSM1900
(PCS1900).
SIM Card
Micro SIM card is inserted
on top part of the Segment
Control Unit.
Micro SD card
Micro SD card is inserted
on top part of the Segment
Control Unit.
A-Bus
1x5 internally connected
signals that are used for
the A-Bus. The internal
connection makes it easier
to daisy-chain to other
controller modules.
RS485
Supports multiple baud
rates. Default value is 9600
bps.
DALI
DALI master without DALI
Power Supply.
Current Sensing
Phase current sensing and
leakage current sensing.
RS232 interface
For use with RS232 power
meters, maximum data
transfer rate 115.2 Kbps.
GPS Antenna
Insert the antenna in the
antenna socket of the
Segment Control Unit and
tighten it gently with your
fingers. Do not use tools.
GPRS Antenna
Insert the antenna in the
antenna socket of the
Segment Control Unit and
tighten it gently with your
fingers. Do not use tools.
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.

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

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.
