Use of measuring unit
Use this setup option only if a suitable measuring unit is available for
determining the optimum timing point, so that the result of a change can be
assessed immediately.
7.5.3
Speed Curve
To optimize the ignition, for example, during the start phase of the engine, a speed curve can be
defined for the MIC6 ignition controllers. To create this curve, up to eight adjustable speed
points are available.
You can configure the speed curve with the MICT. Refer to the section
Timing – Schedule A/B –
General
on page 104.
7.5.4
Ignition Timing Correction
Via the ignition timing correction, the global ignition timing, limited by the timing limits of the
current schedule, can be adjusted. Refer to the section
Runtime Adjustments – Timing
on page
7.6
Firing Angles
The min. distance between two ignition angles depends on the overspeed. The smallest ignition
spacing per output bank can be calculated using the following formula:
7.7
HV-Power Supply Error Monitoring
The voltage applied is monitored for excess voltage or low voltage by the integrated power
supply. For both errors a Power-Fail error is saved and the device shuts off.
7.8
Output Monitoring
Electronic switches are used for the ignition outputs of the MIC6 ignition controller If one of
these switches is defective, this would lead to a primary short or a primary open output. This can
cause problems when operating the engine or can damage the engine. The function of the
outputs is therefore monitored and errors that occur are displayed in the runtime data in the
MICT or can be transmitted via field buses. Different alarms are available for monitoring the
misfire rate. It can also be defined that the ignition is switched off in the event of output errors.
Refer to the section
Inputs/Outputs – Alarms
