The various functions of the ignition timing adjustment are explained in detail in the following
sections.
Influences on ignition timing
Be aware that the actual ignition timing of the engine can also be influenced
by external signals (e. g. 4-20 mA input).
7.5.1 Manual Timing Correction
Explosion hazard!
Never remove the cover for timing adjustment, unless the system is not
located in an explosive environment.
Reinsert the cover after every ignition timing adjustment made using the
potentiometer.
The ignition controllers of the MIC500 series include a permanently installed overwind-protected
potentiometer (Timing Adjustment) for manually adjusting the timing point. The maximum
adjustment range is defined by the user through the corresponding limits.
The potentiometer can be deactivated, e.g. to prevent unauthorized changes in the timing.
The potentiometer is protected by a cover. Remove the cover only if the ignition controller is
located in a non-explosive area. Reinsert the cover after every ignition timing adjustment made
using the potentiometer.
To configure the potentiometer, see sections Activate Potentiometer on page 88 and Set
Potentiometer Limits on page 91.
