DESCRIPTION:
Ignition ICU-L makes possible the selection of preignition curve („short“ or „long“ exhaust stroke). The Setting you can do by supplied shorting jum­per. The setting is permanent stored in memory of ignition even if supply voltage is off after that. You needn’t to do the setting once more after next
switch-on. The next property is light switch-on or switch-off the battery test. That one namely is suitable for Lilon and LiPol battery.

BASIC FEATURES:

– two preprogrammed preignition curves for (“short” – default setting

and “long” silencer),

– sleep mode after 90 sec of engine inactivity,

– battery level signalization (it will not work if battery voltage is lower
than 6,5 V and battery test feature is enabled),
– ignition goes off if engine runs counter clockwise.

– with or without battery test (for Li-Ion or Li-Pol battery),

ENABLING OR DISABLING BATTERY

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 enabled (default settings – programming pins are closed by enc­losed jumper),

- battery test is disabled when jumper is removed and programming pins are open,

- battery test is enabled when jumper is plugged and programming pins are closed.

Enable or disable battery test when the ignition is off.

BATTERY TEST
ENABLED:

- close programming pins with
enclosed jumper.

INSTRUCTION – INSTALLATION AND POWER UP

If you want to change the type of silencer, do first all of two steps and then continue to the next page with title

FIRST STEP:

- 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.

PROGRAMMING SEQUENCE. In the other case follow the next sequence.

SECOND STEP: START:

- connec t enclosed LED to the ignition
(red or red/black wire to left).

- keep clear of the propeller,

- connect battery with the ignition box.

BATTERY TEST
DISABLED:

- open programming pins
(remove jumper).

STARTING 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,

- if battery test is enabled then ignition starts battery test. During this test the series of sparks are generated for cca 2 sec and LED is blinking,

- if battery test is disabled then LED is blinks for cca 2 sec,

- if LED turns off, you can fly, otherwise battery is low.

Type Problem Solution

- fast blinking
(after power up)

battery test is
running

Wait a while.

- fast blinking
(5 sec after power up)

battery voltage
is low

Charge battery. Voltage is lower
than 6,5 V.

- one short flash
per second

sleep mode
spark is
blocked

Unplug battery and reconnect
it again.

PROGRAMMING SEQUENCE – CHANGING A SILENCER

– plug boot to plug,
– plug a battery to the ignition and power it up ,
– wait cca 90 sec until sleep mode is active. Led will start flashing shortly once

per second,

– if batter y test is enabled (jumper is plugged) remove the jumper from program-

ming pins,
– wait cca 3 sec, a flashing sequence changes itself,
– unplug batter y,

To change silencer type to the opposite, repeat whole procedure again (short -> long -> short).

WARNING!

– Use the ignition only in dr y conditions,
– use recommended number and type of cells for every ignition t ype,
– the product is specified for RC engines only (other use must be approved by the

manufacturer),

– do not take off the resister cover if the ignition is on,

The manufacturer is not responsible for damages caused by not following the manual and misuse the ignition other than in RC engines!
You will lost your guarantee if you damage the high voltage (HV) cable or HV isolation, pickup, reverse the batteries or open ignition box!

– danger of elec tric injury (voltage over 20 000 V),
– recharge ignition battery only outside the model,
– because of possible inter ferences, ignition and battery should be placed

at least 25 cm from the receiver!
