Description of function:
1/2
Radial spreader in working
or swathing position
With the road travel circuit unlocked and only with the threshing
mechanism disengaged, switch (U13) is supplied with power.
The position control of the radial spreader requires that another pre-
condition is fulfilled: No signal from the straw chopper speed sensor B28
(uni-spreader) is identified on the CAN bus for at least 2 seconds.
When the radial spreader is in transport position, it moves to the swathing
position first after switch U13 is actuated. To achieve this, the radial
spreader module (A51) actuates solenoid coil Y184 until it reaches its end
position - actual value switch Z59 is closed on pins 1 and 4.
If switch U13 is actuated one more time after the swathing position is
identified - actual value switch Z59 is closed on pins 1 and 4 - the radial
spreader module (A51) actuates the solenoid coil Y185 until the working
position is identified - actual value switch Z58 is closed on pins 1 and 4.
When switch U13 is pressed repeatedly, the radial spreader again
changes between working and swathing position - toggle function.
The master valve (Y77) is also actuated via the diode PCB (DO) in
parallel with the solenoid coils (Y184/Y185) because this function requires
that pressure is built up in the system.
Radial spreader in transport
position
With the road travel circuit unlocked and only with the threshing
mechanism disengaged, switch (U14) is supplied with power.
The position control of the radial spreader requires that another pre-
condition is fulfilled: No signal from the straw chopper speed sensor B28
(uni-spreader) is identified on the CAN bus for at least 2 seconds.
When the straw chopper switch is actuated while in rest position
(U14 = radial spreader in transport position), the radial spreader moves to
transport position.
To achieve this, the radial spreader module actuates the solenoid coils
Y185 and Y174. The actual value switches Z58 and Z59 are not actuated
any more (closed on pins 2 and 3).
When the correct transport position is reached, the actual value switch
Z60 is actuated (closed on pin 1 and 4).
The master valve (Y77) is also actuated via the diode PCB (DO) in
parallel with the solenoid coil (Y185) because this function requires that
pressure is built up in the system.
