7.4.1 Manual Timing Correction
The ignition controllers of the MIC5 series include two permanently installed overwind-protected
potentiometers for manually correcting the ignition timing. The max. range is defined with the
corresponding limits that are set by the user. Potentiometer A adjusts the ignition timing of
schedule A and potentiometer B adjusts the igniting timing of schedule B.
7.4.2 Analog Inputs
The timing point control can be adjusted with a linear current signal. This signal can be
supplied, for example, by a potentiometer, a pressure sensor for charging pressure, or a
detonation controller.
With the analog process signal (current loop signal) at the analog current input, the timing point
can be offset in the advanced or retarded direction within a defined range.
Similarly or additionally, the timing can also be influenced by an analog voltage signal at the
corresponding input.
The levels of the analog inputs can be set in the range from 0 mA to 20 mA and 0 V to 10 V. You
can make this configuration with the MICT. Please refer to the section Timing – Analog Inputs on
page 100.
At the voltage output (Analog Power), a configurable auxiliary voltage is supplied that can be
used for supplying power to external sensors.
