Input Wiring – Timing and Safety Devices

 

Shared auxiliary supply voltage

Devices of the MIC100 series do not have a separate auxiliary supply voltage for the analog current input. For devices requiring such a voltage, the auxiliary supply voltage of the pickup can also be used for the current input.

   

Requirement for auxiliary supply voltage

The auxiliary supply voltage of the pickup can be set via the MICT to 8 V or 15 V (see Engine – Pickups – General). When an auxiliary supply voltage of 15 V is required, the supply voltage of the ignition controller has to be at least 16 V.

Wiring MIC100 ignition controller and DetCon detonation control system

The following diagram shows an example of the wiring of a MIC100 ignition controller with a DetCon detonation control system in cases where the analog current signal (4-20 mA) is to be used for the ignition timing adjustment.

Furthermore, the limits of the analog current input will need to be set at 4 mA to 20 mA in the MICT. Refer to the section Timing – Analog Inputs.

The timing is transmitted by MIC100 via the auxiliary synchronization output (ASO) to the DetCon, and will need to be wired and configured accordingly. Refer to the section Output Wiring – Binary Outputs (Go/NoGo, ASO).
