Wiring for Ignition Controller with ASO Output

No ignition sensor unit (ISU) is required when you use the ignition controller with ASO output from MOTORTECH (e. g. MIC4). In this case, the ignition pulse is transmitted to the DetCon via the auxiliary synchronization output (ASO). The jumper identified with Load Resistance must be removed.

 

Position Load Resistance Jumper

The jumper Load Resistance changes the input resistance of the ignition input.

  • Jumper set: 220 
  • Jumper removed: 1 k

It is on the upper left of the device 1.

Configuration of the ignition controller

In the configuration software (MICT) for the MOTORTECH ignition controllers with ASO output, the adjustments for the DetCon can be easily made using the button Configuration for DetCon2/20. This can be found on the configuration page Input/Outputs – ASO1 (auxiliary synchronization output). Further information can be found in the operating manual of your ignition controller.
