THE IGNITION ICU-S, ICU-P ver. 2.0
DESCRIPTION:
The ignition ICU-S and ICU-P offer special system “easy – start”. This system simplifies engine starting thereby the ignition controls a choke valve.
The choke is controlled by servo connected to the ignition. The ignition processor controls servo according to the program stored in memory. The most
important benefit of this system is easy start procedure. After power-up and battery test (when enabled) only turning the propeller is needed for engine
start. The “easy – start” system protects the engine from flooding or lean air-gasoline mixture when starting.
After power-up and battery test (when enabled) the choke valve position is regulated by the ignition depending on propeller turning. When using “easy
– start” system the ignition must learn both choke valve positions (open and closed). The type of silencer (preignition curve) must be set in programming
mode, too.
Ignition makes enable or disable battery test possible. Battery test is very useful
when Li-Pol or Li-Ion battery are used. During the test a series of flashes are
generated and voltage is measured. When test passed correctly, battery has energy
for minimal 10 minutes of flight.
- battery test is disabled (default settings – when jumper is removed and program-
ming pins are open),
- battery test is enabled – programming pins are closed by enclosed jumper).
Enable or disable battery test when the ignition is off.
ENABLING OR DISABLING BATTERY
BATTERY TEST
ENABLED:
– close programming pins with
enclosed jumper.
BATTERY TEST
DISABLED:
– open programming pins
(remove jumper).
- screw on pickup on engine,
- attach the plastic protection to the high
voltage cable,
- connect boot to plug,
- mount ring tongue terminal on the cable
from boot (ring faston) under a nut holding
the engine to the motor mount,
- fasten ignition to airplane.
- connect enclosed LED to the ignition
(red or red/black wire to left).
- keep clear of the propeller,
- connect battery with the ignition box.
If you want to change the type of silencer, do first all of two steps and then continue to the next page with title
PROGRAMMING SEQUENCE. In the other case follow the next sequence.
- move propeller to open exhaust channel on engine (bottom center),
- put your hands outside propeller radius, otherwise you risk serious injury,
- hold on your airplane, switch on ignition,
- ignition starts battery test. During this test the series of sparks are generated for cca 5 sec and LED is blinking,
- if LED turns off, you can fly, otherwise battery is low.

BASIC FEATURES:
– automatic choke valve control,
– two preprogrammed preignition curves for (“short” – default setting
and “long” silencer),
– one programmable preignition curve,
– sleep mode after 90 sec of engine inactivity,
– with or without battery test (for Li-Ion or Li-Pol battery),
– battery level signalization (it will not work if battery voltage is lower
than 6,5 V (for S) and 9,5 (for P) and battery test feature is enabled),
– ignition goes off if engine runs counter clockwise.
