As can be seen from fig. 241_096, the
electrical mid point does not
correspond to the mechanical mid
point.
In order that a linear output signal
can be produced, this is compen-
sated by the evaluation electronics in
the control unit J556.
A precise fit of the selector fork to the
hydraulic regulator (see description
of hydraulic regulator) and perfor-
mance of basic set-up are also
preconditions for the problem-free
function of the additional shift stage.
When carrying out basic set-up, the
control unit J554 is adapted to
recognise the mechanical end
positions of the selector fork.
Further information can be found in
the “Service” chapter under Basic set-
up.
