Analog Current Input

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.

The level of the analog current input can be set in the range from 0 mA to 20 mA. You can make this configuration with the MICT. Refer to the section Timing – Analog Inputs.

 

Configuration examples

In this example the analog current input is configured in the Timing – Analog Inputs window as follows:

  • Lower Limit: 4 mA
  • Upper Limit: 20 mA

Setting for the analog current input in the window Timing – Schedule A – General:

  • At Lower Limit (4.0 mA): 0° RET
  • At Upper Limit (20.0 mA): 15° RET

Setting for the analog current input in the window Timing – Schedule A – General:

  • At Lower Limit (4.0 mA): 0° ADV
  • At Upper Limit (20.0 mA): 15° ADV
