Detail: Set to FAULT upon the detection of a pattern-specific crank feature while the CrankCount value has
not yet reached the expected value.
Encoder Patterns: Indicates FAULT when an EncZ rising edge occurs before the expected number of Crank
teeth have been counted.
N-M Patterns:
Indicates
FAULT
when a gap occurs before the expected number of Crank teeth have been
counted.
N+1 Patterns: Indicates FAULT when a Plus1 tooth occurs before the expected number of Crank teeth have
been counted.
The FAULT condition causes a loss of sync. Re-sync is not allowed until the flag is cleared by pressing the
SyncFlagClear button.
MissedGapFlag
Tip Strip: Indicates that the crank gap was not detected when expected
Detail: This indicator only applies to N-M patterns . Indicates FAULT when an excess number of crank teeth
are counted before the gap is detected. In other words, physical teeth are received at the location where
a gap is expected. This condition causes a loss of sync. Re-sync is not allowed until the flag is cleared by
pressing the SyncFlagClear button.
MissedCamFlag
Tip Strip: Indicates that the EncZ rising edge was not detected when expected
Detail: This indicator only applies to encoder patterns. Indicates FAULT when an excess number of crank
teeth are counted before the EncZ rising edge occurs.
This condition causes a loss of sync. Re-sync is not allowed until the flag is cleared by pressing the
SyncFlagClear button.
MissedPlus1Flag
Tip Strip: Indicates that the crank Plus1 pulse was not detected when expected
Detail: This indicator only applies to N+1 patterns . Indicates FAULT when an excess number of crank teeth
are counted before the Plus1 tooth is detected. In other words, evenly spaced teeth are received at the
location where a Plus1 tooth is expected. This condition causes a loss of sync. Re-sync is not allowed until
the flag is cleared by pressing the SyncFlagClear button.
