8 Settings via the MICT
Rev. 09/2019 101
– 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 ensured that
the sum of the frequencies at the pickup input does not exceed the limit of 15 kHz at the
pre-set overspeed.
– Speed
Select whether the respective pickup will pick up the signal off the camshaft or the
crankshaft.
