Speed measuring wheel and index setup
Configure the speed measuring wheel according to its physical properties:
Par. 4021 = 0 for a wheel equipped with teeth
Par. 4021 = 1 for a wheel equipped with holes
Par. 1 = Number of teeth / holes.
If the measuring wheel has a single tooth/hole gap (firmware variant B1), the gap is
counted as 1 tooth / hole. For example a 120-1 teeth wheel Par. 1 = 120.
If the measuring wheel has a double tooth/hole gap (firmware variant B2), the gap
is counted as 2 teeth / holes. For example a 60-2 teeth wheel Par. 1 = 60
Configure the index according to its physical properties:
Par. 4026 = 0 for a single tooth index
Par. 4026 = 1 for a single hole index
Pick-up and index angle position setup
The position of the speed measuring wheel gap resp. of the index must be determined ex-
actly. The ignition TDC of the cylinder selected first (cylinder A1, TDC is equivalent to 0°
crankshaft angle) is used as a reference point. All distances (including that of the speed
measuring wheel gap or of the index on the camshaft) are to be specified in degrees of
crankshaft angle before the compression TDC of cylinder A1.
Procedure to determine the distance (see pictures following):
1. The crankshaft is rotated into a position where cylinder A1 is exactly at TDC (ignition TDC).
2. For Hall Pick-ups: The distance between the centre of the sensor and the beginning
or the end (depending on Par. 4024 and 4029) of the first tooth after gap is measured by
degrees of crankshaft starting from the sensor in direction of engine rotation.
3. For Inductive Pick-ups: The distance between the centre of the sensor and the centre
of the first tooth after the gap is measured by degrees of crankshaft starting from the sen-
sor, in the direction in which the engine rotates.
