Description of function:
Folding the maize picker /
Snapping plate adjustment
When the road travel circuit is unlocked, relays K3, K4 and the fold maize
picker switch (S34) are supplied with power by relay K49. The
pushbuttons (37c/37d) actuate one of the two solenoid coils (Y46/Y47) via
the corresponding relay K3 or K4 for snapping plate adjustment whereas
switch (S34) directly controls the solenoid coils (Y42/Y43) in order to fold
the picker.
The master valve (Y77) is actuated via the diode PCB (DO) in parallel
with one of the solenoid coils (Y42/Y43/Y46/Y47) because this function
requires that pressure is built up in the system.
The reel controller module (HAS) (A16) converts the analogue signal from
sensor (B55) into a digital signal which is displayed on terminal (A30) via
the CAN bus. Sensor (B55) receives the necessary 12 V reference
voltage from the actuated road travel main relay K49/87.
Down maize auger drive The down maize augers are driven hydraulically by the reel drive variable
displacement pump. The reel controller module (A16) controls the speed
– circuit diagram 22a
The speed adjustment is by means of the +/- keys on the terminal (A30).
Since there is no speed sensor for speed monitoring/control, the
automatic reel speed control in the terminal (A30) must be switched off.
