Description of function:
1/2
Threshing drum variable-
speed drive
When the threshing mechanism is engaged, a CAN bus signal is
transmitted to the fieldwork computer module A10 by the +/- pushbuttons
(T19/T26) provided that the function pre-selection rotary switch (T11) is
set to the threshing drum position. The fieldwork computer module A10
controls the corresponding solenoid coils (Y19/Y20).
The master valve (Y77) is also actuated via the diode PCB (DO) in
parallel with the threshing drum fast solenoid coil (Y20) because this
function requires that pressure is built up in the system.
The fieldwork computer module (A10) ensures the actuation of the
solenoid coils (Y19/Y20) and the control of the master valve (Y77) even
during the automatic crop selection.
The fieldwork computer module (A10) reads in the threshing drum speed
actual value via sensor B11 (threshing drum speed) during automatic crop
selection.
Threshing drum speed
signal display
The fieldwork computer module (A10) reads in a signal from sensor B11
(threshing drum speed). The fieldwork computer module (A10) converts
this signal and displays it on terminal A30 via the CAN bus.
Concave adjustment A CAN bus signal is transmitted to the speed monitor module (DZW) A12
by the +/- pushbuttons (T19/T26) provided that the function pre-selection
rotary switch (T11) is set to the concave position. The speed monitor
module A12 controls the corresponding solenoid coils (Y17/Y18). The
circulation shut-off valve (Y77) is actuated via the diode PCB (DO) in
parallel with one of the two solenoid coils (Y17/Y18) because these
functions require that pressure is built up in the system.
The speed monitor module (A12) ensures the actuation of the solenoid
coils (Y17/Y18) and the control of the circulation shut-off valve (Y77)
during the automatic crop selection. The speed monitor module (A12)
reads in the concave adjustment actual value via the concave position
sensor B30 during automatic crop selection.
