3.1 Functional Description
The devices of the MIC500 series are microprocessor-controlled condenser discharge ignition
systems, which provide the ignition energy for gas engines with up to 16 cylinders.
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 MIC500 series use information supplied by the pickup to precisely
determine the correct timing for the respective outputs. An event type N+1 trigger disc serves as
transmitter.
The timing is influenced by various inputs made either automatically or manually. This can be
implemented with the installed manual potentiometer, an analog input signal (4-20 mA) or a
configurable speed curve.
By checking the information received, the ignition controllers continuously monitor the system
status of the pickup and the correct operation of the primary ignition circuit during operation.
Depending on the severity of an error that is detected, the devices will shut down immediately or
warn the operator by a flashing LED.
To protect the engine, the ignition controllers additionally have an adjustable overspeed shut-
off.
3.2 Applications
Depending on the device type, the ignition controllers of the MIC500 series are designed for
specific 2- or 4-stroke gas engines. Depending on the device type, there are between 2 to max.
16 ignition outputs available.
The ignition controllers supply the energy output required for the corresponding ignition coils of
the gas engines and can supply signals for peripheral devices. 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.
