Active pickups
Check when using active pickups that the auxiliary supply voltage is configured for your application.

Pickup Setup Information
The settings made in the section Pickup Setup were summarized once again in the section Pickup Setup Information.
Pickup Setup
Enter the following settings in this section:
- Predefined Setup
Select the pickup configuration suitable for your application from the list. The configurations available for selection depend on the previously entered settings. - Index/Reset Position
Enter the distance between the first event after the set index/ reset marking and top dead center. With the button Adjust, you can enter the measured firing angle for a given nominal value. The system calculates the difference from these values, which is added to or subtracted from the index/reset position. - Pickup Sensitivity
Open the pick list and select the desired sensitivity level for the pickup. This setting overwrites the value of the pre‑trigger voltage if the latter was defined in the user-defined pickup setup.- High
The signal processing starts at low engine speeds. This setting can result in increased susceptibility to failure. - Medium
Default setting for MICT. This is a trade-off between start-up speed and sensitivity.
- Low
The signal processing does not start until high engine speeds are reached. This setting can result in reduced susceptibility to failure.
- Trigger/Cam No. of Triggers
Enter the number of events. The input Cam or Trigger is automatically selected by the MICT and is governed by the selection of the pre-defined pickup settings. - User-defined
Staff authorized to access the Advanced Service level can, in addition to the standard settings access, use a manual setup option by clicking on the button User-defined.

- Type
You can select the type of events that will occur on this input for each pickup input. Type and number of events are defined by the discs or ring gears used. If you decide not to use a pickup input, select the entry None from the list. You can set the following types:
N
Disc, which causes a uniformly distributed number (N) of events (per rotation), e.g. a ring gear with 160 teeth (N=160).
N+1
Disc type N with one additional event, e.g. a disc with 12 teeth and one additional tooth for the index signal (N=12).
N+1 extended index range
Disc type N with an additional event, e.g. with one disc with 12 teeth and one additional tooth for the index signal (N=12). The permitted range for the index signal is expanded to 75 % of the tooth period. An incorrect direction of rotation of the engine cannot be detected by this setting.
N-1
Disc type N, where one event is missing, e.g. a ring gear with 160 teeth on which one tooth was removed (N=160). This missing event is used to determine the index signal
N-2
Disc type N, where two consecutive events are missing, e.g. a ring gear with 60 teeth on which two teeth located next to each other were removed (N=60). This missing event is used to determine the index signal.
N Magnets, Single Magnet
You will always use these two types together for a disc with magnets having opposite polarity. A magnet with a fixed number of magnets (N), all of which are arranged at equal distances on the disc, has a reverse polarity. Thus, the disc supplies two signals that can be analyzed by a pickup.
Single Event
Disc that supplies a single event, e.g., a disc with one tooth or one magnet. - Number of Events
Enter the number of events that occur on the pickup if more than one event is expected. For the types N+1 and N-1, enter the value for N and not the total number of events. With the type N Magnets, the number of magnets with identical polarity must be entered.
The number of events must lie between 3 and 500. Additionally, it must be taken into account that the sum of the frequencies at the pickup input does not exceed the limit of 10 kHz at the pre-set overspeed. - Speed
Select whether the respective pickup will pick up the signal off the camshaft or the crankshaft. - Active/Passive
Select the pickup to be used from the pre-defined pick list:
Passive
passive pickup
Active (low)
active pickup with high level as quiescent level
Active (high)
active pickup with low level as quiescent level - Pre-Trigger
Enter a value between 0.1 V and 7.5 V for each pickup to set the pickup sensitivity level. Signals that fall short of the set voltage will not be analyzed. A low pre-set value therefore results in a high sensitivity level, a high value results in a low sensitivity level.

Pickup setup information
The respective latest setting in the area of the pre-defined or arbitrary pickup settings is transferred to and displayed under Pickup Setup Information.

Aux. Pickup Supply Voltage
Enter the supply voltage with which the active pickup is to be operated. A value between 5 and 24 V is possible.
Speed Settings
Enter the following settings in this section:
- Ignition Release
Enter the release speed for the ignition at which the first ignition is to fire. The value shall not exceed 1/7 of the nominal speed. - Security Speed
Enter the security speed. Below the value entered, the ignition can be switched on and off as desired. If the ignition is deactivated during operation above the set speed, the ignition cannot be immediately reactivated. Only when the ignition no longer reads a speed, i.e., the engine has come to a standstill, can the ignition be reactivated. - Nominal Speed
Enter the nominal speed at which your engine is to be operated. With engines that are to be operated with variable speeds, the max. speed of the operating range must be entered. - Overspeed
Enter the speed at which the ignition is to be shut off as overspeed protection. With engines that are to be operated with variable speeds, a speed above the operating range must be entered. - Max. Power-on Speed
Enter the maximum permitted start speed at which the MIC3+ starts sending ignition pulses.
A value of 6000 rpm is set as the default value: The MIC3+ can be activated at the starter speed and immediately send ignition pulses.
For a value of 0 rpm the MIC3+ can only start sending ignition pulses once it has registered that the engine is at a standstill.
