Intelligent Lighting Controller
Model: ILC- 4ch
Intelligent Lighting Controller (ILC-4ch) is an electronic controller designed
specifically to operate the lighting circuits used in homebuilt aircraft. ILC
provides control of up to 4 lighting circuits plus dimmable control of up to 3
channels of instrument and cabin lights. The 4 lighting circuits may be used to
control landing lights taxi lights strobe lights and navigation lights. Each
channel is independently powered and controlled. ILC also provides a wig-wag
function between two of the lighting circuits. Each lighting circuit may control up
to 10 amps of load. The 3 channels of dimmable lighting may be independently
controlled. Each dimmable channel may include incandescent or LED lighting
up to 1 amp.
ILC-4ch utilizes a remote mounted power electronics module that
communicates to instrument panel mounted switches and potentiometers. This
system allows for considerably less wiring behind the aircraft instrument panel.
The remote mounted power electronic module may be mounted in the aft area of
the aircraft allowing for short wire runs for the power wiring between the aircraft
power bus and lighting loads. The ILC works with any standard switches and
supports both backlighting and switch indicator lighting. Additionally ergonomic
environmentally sealed back-lit switches are available for use with the ILC
system as well as other electrical loads. A single multi-conductor cable may be
used to link the switches and potentiometers on the instrument panel to the
power electronics module. The switches are operated at very low power levels
thereby providing extremely long service life.
The power electronics module contains no relays and each lighting circuit
is independent from the other thereby providing very high reliability. Each
dimming channel is independently controlled and is over temperature and over
current protected. ILC-4ch also contains a wig-wag function for improved aircraft
visibility. Lighting circuits 1 and 2 (typically connected to the landing light and
taxi light) may be alternated flashed at a 150 cycle per minute interval providing
additional collision avoidance for the aircraft. The wig-wag function is
independently controlled however is overridden by the selection of the landing
light or the taxi light. Additionally the wig-wag function provides a 1 minute
start-up delay.

ILC-4ch must be installed using the current aircraft standards and
practices. Refer to AC 43.13-2A/1B. The installer/builder is solely responsible
for determining the suitability of the installation and use of this product.
Installation instructions:
1. Mount the lighting switches in the instrument panel in a suitable location
route a 13 conductor cable (shielding not required) to the mounting area
for the power electronics control module. (24 awg. conductors minimum).
Connect the switches to the multi-conductor cable as shown in the wiring
diagram. NOTE: if no taxi light is used and the wig-wag function is to be
utilized follow the alternate wiring diagram.
2. Mount the dimmer potentiometers in a suitable location wire per the wiring
diagram.
3. Mount the power electronics control module in a suitable location. The
module may be mounted in any orientation. The power electronics
module must not be mounted in the firewall forward area.
4. It is recommended that a dedicated fuse block for providing power to the
lighting circuits be mounted in close proximity to the power electronics
control module.
5. Provide up to 4 separate 10 amp fused power circuits from the aircraft
power bus to the ILC-4ch power electronics control module. Provide 1
separately fused 3 amp power circuit for the instrument lighting circuit.
6. Provide a ground connection to the terminal marked using at least 18
gauge wire.
7. Connect the lighting loads to the respective Switched Outputs #1 thru #4.
Switched Output #1 = Landing Light
Switched Output #2 = Taxi Light ( or second landing light)
Switched Output #3 = Strobe Lights
Switched Output #4 = Navigation Lights
8. Connect the dimmed lighting loads to the respective Dimmed Channels
#1-3. Note: Dimmed Channel #1 provides dimming of the back-lit
switches on the control panel therefore it is recommended that any other
illuminated switches requiring dimmer control are recommended to be
connected to Dimmed Channel #1.

PRODUCT OPERATION:
Each switch connected to the remote power electronics module controls
one of the switched outputs. The switch used with the Taxi/wig-wag inputs
must be a center off SPDT type switch. This enables the selection of Taxi
lights OR the Wig-Wag function. The wig-wag function will alternately drive
the landing light and taxi light at a 150 cycles per minute interval. Each light
will be on for approximately 200 milliseconds then the other light will be
energized. The wig-wag function is started after a 1 minute warm-up period.
During the warm up period both the landing light and the taxi light are driven
continuously at full power. After the 1 minute warm up period the lights will
begin flashing at the 150 cycle per minute interval. The wig-wag function is
cancelled by moving the taxi light switch to the Taxi position; this allows the
taxi lights to be continuously on. The wig-wag function can also be cancelled
by turning on the landing light. If the landing light is turned on and the taxi
light switch is left in the wig-wag position the taxi light will remain off. If the
landing light is turned on and the taxi light switch is moved to the on position
both lights will be on continuously.
The three dimming channels are controlled by the potentiometers labeled.
When the pots are turned fully counterclockwise the respective dimmed
channel will be at minimum power.
Dim1 channel also controls the back lighting for the switches on the switch
panel. It is recommended to use Inst 1 channel to control the backlighting on
other switches on the instrument panel.
