Description of function:
Swinging the grain tank
unloading tube
The grain tank unloading tube swing function is controlled by the grain
tank module A34. With the road travel circuit unlocked, the grain tank
module A34 is supplied with power.
Depending on the direction (swinging in or out), the switches (S87/S88)
transmit an earth signal to the grain tank module A34. The grain tank
module A34 actuates the corresponding grain tank unloading tube swing
out solenoid coil Y33 or grain tank unloading tube swing in solenoid coil
Y34.
The master valve (Y77) is also actuated via the diode PCB (DO) in
parallel with the solenoid coils (Y33/Y34) because this function requires
that pressure is built up in the system.
Grain tank unloading tube
swing time control
When one of the switches (S87 / S88) is actuated, the Swing unloading
tube function remains active for 20 seconds.
Actuating a switch (S87 / S88) briefly one more time stops the swing-
in/swing-out movement of the unloading tube.
Grain tank unloading tube
swung out warning
To display the unloading tube swung out warning, the Unloading tube
swung out switch Z30 transmits an earth signal to terminal A30 (see also
diagrams 5 and 15).
