3.1 Functional Description
The devices of the MIC5 series are microprocessor controlled ignition systems, that are
comprised of one 32 bit main processor (CPU) and an output board.
Please note that the manufacturer is not required to implement configurations of the ignition
controller for specific engines, and that devices may be delivered without pertinent
configuration.
The ignition controllers of the MIC5 series use information supplied by the pickups to precisely
determine the correct timing for the respective outputs. The timing is influenced by various
inputs made either automatically or manually. This can be implemented with manual
potentiometers, the analog input signals, a speed characteristic, or with a serial interface (USB,
CAN bus, RS485).
During operation, the ignition controllers continuously monitor the system status of all installed
pickups and the correct operation of the primary ignition circuit by checking the information
received.
Depending on the severity of an error that is detected, the device will shut down immediately or
warn the operator. A corresponding message can be viewed on a connected PC.
To protect the engine, the ignition controllers additionally have an adjustable overspeed
shut-off.
3.2 Applications
The ignition controllers of the MIC5 series are designed for specific 2- or 4-stroke gas engines.
From 1 to max. 20 ignition outputs are available. The ignition controllers supply the energy
required for the corresponding ignition coils of the gas engines and can supply signals for
peripheral equipment.
Any use other than the one described in the operating manual shall be considered improper use
and will result in the voiding of all warranties.
