intelligent Ignition System with microprozessor controlled auto timing
General
For optimum operation of combustion engines an ignition system with auto timing is necessary. For easy starting
up a spark is ideal in the upper dead point position of the pistion. With increasing rpm a pre-ignition timing up to 30
degree is needed.
This is achieved with our new system using a high precision rpm-check by two magnets built-in the hub of the engine.
The hallsensor transmits the signal to the microprocessor, programmed with our engine characteristic.

Like all other electronic devices the ignition box gets warm under operating conditions. For that reason a simple
airflow has to be guaranteed. Therefore the 4 delivered rubbermounts have to be used for installation, insuring a
one millimeter gap underneath the box.

Info about red LED
a) Ignition battery switched on:
b) Propeller one turn (flip):
c)
Propeller not being turned (flipped), after
twenty seconds:
- the engine cannot be started by coinsidence if sombody forgot to switch off the ignition
- battery will be protected against incidental discharge
d) in case the LED will not get off when propeller is turned (fliped): hall sensor is not connected or other defect
