Installation
Location
• Source Controllers must be located in a dry, well ventilated location
where the ambient temperature is within the range of +2oC to 40oC
(humidity of +5 to +95% non-condensing).
• Source Controllers are designed to be mounted vertically on a stable,
horizontal surface. It is important to orientate the unit correctly to allow
for effective airflow for ventilation.
It is recommended to leave 100mm distance between the Source
Controller and walls or other equipment either side of the unit.
• A Source Controller may be connected directly to trunking of depth
50mm or less (see right, top).
• Where trunking depth is greater than 50mm, a gap of 50mm is
recommended to allow for adequate airflow for ventilation (see right,
bottom).
• Allow adequate space for future maintenance of the unit. Do not install
in a location that will later be inaccessible.

Four screws hold on the cover of the Source Controller; two are visible from the front and two are visible
only when the MCB cover door is opened. There is no need to remove the MCB door.
Load Connections
It is essential that the correct Source Controller is used according to load type. Consult the table below if
you are unsure about load type before connecting the load to the Source Controller.
IMPORTANT: Failure to use the correct Source Controller or load type has the potential to damage the
Source Controller, load, or both and is not covered by product warranty.

Network Connections
Network Cable Topology
The iLight Network is of CAN bus (Controller Area Network) standard. A maximum of 100 devices can
be added to the network on a single run. NOTE: Device quantity can be increased with a BN-2-D Network
Bridge/Repeater unit.
The network must be wired in a ‘daisy-chain’ radial configuration, resulting in two end-of-line positions for
the CAN pair. The order that devices are situated on the network is not specific, but power must be evenly
distributed across the network for powering Control Plates, Interfaces and other input devices. Additonal
power supplies may be required.
Simple Network Example
EoL Termination
EoL Termination
Source Controllers
Control Plates
Three-phase Operation
SCA1210 maintains output terminal order
according to channel number, rather than
grouping the outputs together by phase.
For SCA1210, the output LEDs to the right-
hand side of the unit are grouped by phase.
This is because each of the three Power
PCBs are controlling each of the phases.
Therefore, if the second LED down on the
right side of the unit is on, and the circuit
needs to be isolated, this corresponds to
the second output of phase L1, which is
output channel 4 and therefore breaker
number 4 on the Source Controller.

Service Switches and LEDs
These switches and LEDs are located at the base of the unit.
The two service switches on the source controllers are used for the following:
• Entering Diagnostic Mode.
• Putting the Source Controller in
override mode.
• Sending a message to identify the
device on the network.
• Sending a message to identify the
device on the network.
The LEDs indicate the following:
• Normal operation:
Steady green LED blinking 1 x per
second.
Red LED off.
• Message transmission and receipt
indicated by red LED flashing for
duration of data transmission.
• Override status: Both LEDs flashing
together or just red flashing and
green off.
ICANnet error status will occur when a
Source Controller is not connected to an
iCAN network for any reason. Once either
connected to a network of one or more other
devices which are powered the error status
will be removed. It is still possible to enter
Diagnostic mode if a Source Controller is in
iCANnet error status.

iLight SCA0410 & SCA1210 Installation Guide Document 9850-000927-00 P9
Override Mode
Placing the unit into override mode
allows for testing of the Source Controller
outputs regardless of how the unit is
currently programmed. This is useful
for ttesting power to circuits prior to the
system being commissioned or for fault
nding where it can be used to test if there
is an issue with the Source Controller
output(s) should this be suspected.
When the Source Controller is placed into
override mode it will no longer respond to
commands sent over the iLight network.
Override mode can also be used to
restore power to outputs if control is lost
or temporarily removed to allow lighting
to remain on until control is restored.
NOTE: Override mode only affects the
outputs on the Source Controller on
which it is activated.
To exit diagnostic / override status follow
the steps shown. If power is cycled to the
Source Controller then this will also take
the unit out of override mode and it will
start up in the default running status.

RS485-
Source Controllers have an RS485 port located on the CPU PCB which allows for direct serial integration
with the iLight network. If multiple Source Controllers are linked on the iLight network then only a single
RS485 connection is required in order to potentially control all devices.
Use CAT5 FTP or equivalent data cable
for the RS485 connection.
The pin marked Alarm should be
ignored. This feature is covered in the
Alarm Input section.
This port can also be adapted to be
used as a DMX input port for DMX
control of the Source Controller’s
outputs. It cannot be used for this
purpose if it is already being used as
an RS485 port. This feature is covered
in the ‘Output Control by DMX Input’
section.

DMX Input Connection
Function
Alarm (N/A)

DMX+
DMX-
Source Controllers have an RS485 port located on the CPU PCB which allows for direct serial integration
with the iLight network. This port can be converted into an input connection for DMX control of the Source
Controller by a lighting desk, for example. To enable DMX control a DI-1 DMX Input PCB must be fitted to
the Source Controller.
Use Belden 9729 or equivalent data cable
for the DMX connection.
The pin marked Alarm should be ignored.
This feature is covered in the Alarm Input
section.
The port cannot be used for DMX input if
it is already being used as an RS485 port.
DMX input is per Source Controller,
meaning that this conversion and
connection must be made to all Source
Controllers that are required to be
controlled via DMX input.
• A maximum of 32 devices can occupy a single DMX
segment (including the Source Controller) with a total
cable length of 300m.
• DMX must be terminated at the end-of-line with a
120ohm value resistor, as per the CAN network.
• Source Controllers will act like a DMX device and DMX
addressed must be assigned to each output of the
Source Controller. By default this is 1-4 or 1-12.
• The DMX address is assigned to each output through
iLight programming software, and each output can
be assigned a value between 1 and 512. Any outputs
assigned to the same DMX address will therefore
respond as a group.
For more information on DMX control and wiring topology, please consult the ‘Introduction to DMX’ article
available at www.iLight.info.
(Above) The DI-1 DMX Input card plugs into
the 10-pin socket on the CPU card. The
Source Controller’s power must be reset
after installation in order for it to recognise
the PCB.

Alarm Input Connection
Function
Alarm
0V
N/A
N/A
Source Controllers have an Alarm Input located on the CPU PCB which allows for direct connection of a
volt-free contact closure input from a fire or security system.
When a contact closure occurs across the normally-open Alarm and 0V terminal on the Source Controller,
an alarm scene is triggered which is broadcast across the iLight Network to all other devices.
The default scene setting is all channels to 100%. Control Panels are also configured by default to be
locked when the alarm link is in place to disable manual override of the lighting during an alarm.
Upon release, channels will return to the last selected scene levels and Control Panels will be re-enabled.
The Alarm Scene can be reconfigured when the Source Controller is programmed and it is possible to set
other devices on the network to ignore the alarm status if control must be maintained to some outputs or
Areas.
NOTE: The Alarm connection cannot be adapted for use as a volt-free inputs for other purposes, such as
sensors. UIG2 Universal Interfaces, UIM Mini Universal Interfaces and UIS Sensor Interfaces are required
for additional input requirements to the iLight Network.

Troubleshooting
The loads are not switching on when I first power up
the Source Controller.
Check for voltage on the output terminals to ensure
that this is not a wiring issue to the load(s). Make sure
that the green CPU card status LED is blinking slowly
(1x per sec).
If you have already connected up the networked Control
Plates or Touchscreens to the unit then try selecting the
factory scenes from these.
You can override the unit to get the lighting on to 100%.
Please refer to the Override Mode instructions on
page 9.
There are one or more outputs stuck on and cannot
be turned off.
First, check the alarm status is not active as this will set
all channels to full. If the alarm status is not active, cycle
the power to the device. This will reset the controller.
If the fault doesnt clear, contact the iLight helpdesk
The Source Controller has power but none of the
outputs can be controlled from Control Plates or
Touchscreens.
Make sure that the green CPU card status LED is
blinking slowly (1x per sec). Check to see if the red LED
to the right of this flashes when operating the lights. You
may need to test your network cable in case there is a
break or a broken connection somewhere.
Check that the black ribbon cable is fully inserted into
the 26 pin socket.
If no LEDs are lit on the CPU card of the Source
Controller, but power is present, this suggests that the
CPU board or its transformer has a fault and may need
replacing or repairing.
I am using Device Editor and cannot find the Source
Controller when searching for devices.
Please see above suggestions. Also, press the button
to the left of the green LED on the CPU board to ping
the Source Controller. This should make it appear in
the search window and display a message in the iLight
network monitor window.
If your issue is not covered by any of the above
please contact iLight Technical Support.
The email address and telephone number can be found
on the back page of this manual.
