The electronic unit monitors the following in order to control the automatic
functions:
- Drive speed
- Feed rake speed
- Rotor speed
- Knives position
- Opening angle of cutting frame
Rotor plugged When the rotor is plugged in automatic mode (drive speed > 500 rpm), the
knives are moved out, the cutting frame is possibly opened, depending on
the configuration, and then closed (see "Rotor plugged" sequence
diagram).
Feed rake plugged In case of feed rake standstill, the rotor drive is additionally disconnected
via the solenoid Y 58 (see "Feed rake plugged" sequence diagram).
Note: For cabling of the corresponding solenoid valves see circuit
diagram 7a.
- Speed sensors
(B9, B23, B24)
The clearance between the HALL sensors and the tooth top should be
approx. 1.5 ± 0.25 mm(Pitch of sensor threads: 1 mm).
At a drive speed of approx. 350 rpm, the speed values should be
displayed correctly in the CDS diagnosis system.
HALL sensor (B67) The cutting frame angle can be read using the CDS diagnosis system.
When the cutting frame is closed, the displayed value must be - 2°.
HALL sensor (B111) The ROTOCUT knives position angle can be read using the CDS
diagnosis system. With the knives retracted, the displayed value must be
> 35°.

Description of function:
Pressure setting The pressure of the baling chamber cylinders 334 is pre-selected in
terminal A 30 (set value).
According to the pre-selected value, a pressure in the baling chamber
cylinders 334 is regulated (actual value) via module A20 and the baling
pressure build-up solenoid coil Y 50.
Control of the baling pressure build-up solenoid coil Y 50 is by pulse-width
modulation (PWM).
Baling pressure monitoring The set pressure of the bale chamber cylinders 334 is monitored by
sensor B 56. This value is displayed in terminal A30.
Baling pressure reduction
for "Eject bale" function
When sensor B113 identifies the "Eject bale" function (reversing valve in
corresponding position), module A20 regulates the baling pressure to
0 bar.
This can be seen in terminal A30 by the inverted baling pressure symbol
(see circuit diagram 13a).

Bale length The desired bale length is pre-selected in terminal A 30. The metering
wheel / bale length sensor B 69 detects the bale length. Both values are
compared in module A20. When they are identical, wrapping is released.
Wrapping release Wrapping is released by module A 20 by a short switching pulse. When
motor M1 is near its parking position, pin 53 is internally connected with
pin 31b. The induced voltage electrically brakes motor M1 via relay K 92
against earth.
Following a wrapping release, the electronic unit must detect at least
0.4 metres of bale length before wrapping can be released one more time.
Wrapping monitoring Generates the „Wrapping fault“ error in terminal A 30 if the wrapping
system monitoring sensor B112 transmits a signal without wrapping
command (from module A20) at a drive speed of > 500 rpm.
Wrapping is now electronically blocked
(see Wrapping fault sequence diagram).
Knotter cleaning fan The fan motors run only while the wrapping cover is closed (Z100). When
opening the wrapping cover (e.g. for service work), relay K100 drops out
and consequently cuts the electrical connection with the knotter cleaning
fan motors (M27).

Description of function:
Identification of operating
mode
The operating mode pre-selected at the reversing valve 633 – Bale
ejector or bale ramp - is transmitted to module A20 as a signal by sensor
B113.
This is required for the switches to work properly according to their layout
front = raise bale ramp / retract bale ejector
rear = lower bale ramp / extend bale ejector
Note: Module A20 controls the baling pressure to 0 bar when
- sensor B113 detects the bale ejector position
- the bale ejector is actuated via switches U1/U2
A baling pressure of 0 bar is indicated in terminal A30 by the
inverted „Baling pressure“ symbol.
Ejecting bales
Operating the bale ramp
When module A20 identifies a signal from switches U1 or U2, module A20
actuates bale ejector / bale ramp pre-selection solenoid coil Y149.
In parallel with the function, the solenoid coils Y150 Direction P - A
reversing valve or Y151 Direction P - B reversing valve are actuated.
(See also Technical Systems – Hydraulic System)
Bale length The bale length determined by the metering wheel upon bale ejection is
saved in module A20, but not directly displayed in terminal A30.
In the next use, the saved value is added to the following bale and will
then be displayed in terminal A30. This value remains saved even after
switching off terminal A30.
