Layout of electric circuit diagrams Following the circuit diagram layout, all electric circuits are shown in individual circuit diagrams. Some explanations are given below to illustrate the layout.

Numbering of circuit diagrams Me-e-01a

-

The respective numbering can be found on the corresponding cover sheet and in the footer.

Depending on the machine no., the components fitted and the country specification, there may be several individual circuit diagrams 01b, 01c, etc. for a given function.

Potentials -

Main power supply (battery) Ignition switch power supply (switched) Relay-controlled power supply Earth Housing earth (external)

Connections -

The description provided inside the circle (e.g. „S52”) defines the connection.

Numbers next to the circle (e.g. „4”) describe the continuation of the cabling in accordance with the circuit diagram numbering. This circuit diagram numbering can be taken among others from the footer.

Example:

Many electric circuits depend on the road travel activation switch S52 (see circuit diagram 04a). Therefore there are functions on circuit diagrams 20, 24 and 30 which can only be activated when S52 is closed.

Designations -

Connectors (e.g. „MFAgn”, pin 3 and 5) .

Each chapter lists the respective connectors and their pin assignment in the individual connection tables.

-

Modules (e.g. „A12 - Speed monitor“) The arrows identify the functional inputs and outputs according to the assignment table provided in chapter ZE.

Electric system

Description of function: A plus potential (+30) is fed in via the central power supply from the positive terminal of battery (G1) and/or from generator (G2) pin 30. The minus terminal of battery (G1) and the central earthing point (-31) are connected to the machine chassis.

Ignition ON

With the ignition switched on, battery plus (+30) is passed on as switched plus (+15) via the ignition switch (S64).

Electric starting motor circuit

The start relay K11 is used as safety start switch only if the ground speed control lever is in neutral position and consequently the ground speed control lever safety start switch (Z57) is closed. At the same time, the threshing mechanism must be switched off at switch S 25. When the power supply is applied at the electric starting motor, the start relay (K11/87) applies a signal voltage in parallel to the electronic engine control module (A15) and sets the electronic injection unit to start mode.

Generator release

With the generator (G2) running, the generator release relay (K61) switches battery plus (+15) on to generator release relay (K61/87). Perfect generator function therefore is the pre-condition for the system operating voltage (see circuit diagram 3).

Generator charging light

With the ignition switched on, the generator charging light (H19) must light up in order to excite the generator (G2) internally.

When the generator charging light (H19) lights up while the engine/generator are running, no charging voltage is generated – a total failure of the generator must be assumed. In this case, buzzer H 44 and the signal lights "Stop" (H42) in the operations display screen and/or the warning light (H45) on the vehicle information unit are permanently activated as a warning (see circuit diagram 3).

Description of function: Engine oil pressure warning

If the engine oil pressure falls during operation (relay K61 actuated), the oil pressure switch Z 42 closes and earth is applied to pin 85 of relay K 59 – the relay switches. The following items are activated permanently in this case: Buzzer H 44 (pulse-type buzzer) Warning lights H 42 in the operations display screen Warning light H 45 on vehicle information unit Warning light H 50 engine oil pressure over diode PCB Warning light H 21 is activated.

This earth is simultaneously applied as a signal to module A 17.

Important!

Temperature display

When the oil pressure is too low, there is no automatic engine cut-off. The oil pressure switch Z 42 only switches the warning instruments. Another oil pressure switch (Daimler/Chrysler component) here provides automatic power reduction.

The temperature sensor (Daimler/Chrysler component) transmits its signal to the electronic engine control module A15. From there, this signal is passed on to the engine adaptation module A 17 via the CAN bus.

The engine adaptation module A 17 converts the digital signal into an analogue signal and transmits it to indicator P8.

Important!

When the temperature signal exceeds the defined limit value, the electronic engine control module A15 automatically reduces the engine power. One acoustic and optical warning is given in case of excess temperature.

Overtemperature warning

The “Overtemperature warning” can be caused by several events: cooling water temperature signal too high while engine power is reduced low oil pressure low oil level (when oil level sensor is parameterized) The engine adaptation module (A17) actuates the signal light H24 and the warning buzzer K77 at the same time via the relay.

Buzzer (pulse buzzer) H 44 Warning lights H 42 in the operations display screen Warning light H 45 on vehicle information unit

Air filter warning

In case of excessive air filter clogging, switch Z 69 closes. In this case, warning lights H 46 and warning light H 21 via the diode PCB are activated permanently.

At the same time, the following items are activated in a pulsed way via pulse relay K 58: Buzzer H 44 (pulse-type buzzer) Warning lights H 42 in the operations display screen Warning light H 45 on the vehicle information unit is activated permanently.

Coolant level warning

Ignition ON, diesel engine is not started (relay K 61 is not actuated). In case the coolant level is too low, switch Z 33 closes.

In this case, warning light H 18 lights up permanently.

After actuating the Road travel switch S 52, the voltage applied at branch K 61/87 is passed on via relay K 60. The new branch K60/87 thus created supplies most of the electro-hydraulic circuits.

Master valve

In order to be able to build up the necessary working pressure for many hydraulic controls, the neutral hydraulic circulation must be blocked (see also the "Hydraulic system" section). In this case, the master valve solenoid coil (Y77) is actuated directly via the diode PCB (DO) in parallel with the function.

Description of function: Threshing drum variablespeed drive

09/06

The threshing mechanism clutch switch (S25) must be closed before the threshing drum variable-speed drive can be adjusted.

Moreover, the changeover switch (S65) must be set to the threshing drum display. See circuit diagram 10 Only when these conditions have been met, earth is applied to the threshing drum speed adjustment switch (S98) which enables increasing (Y20) or decreasing the threshing drum speed.

The master valve (Y77) is also actuated via the diode PCB (DO) in parallel with the threshing drum speed adjustment because the threshing drum speed increase function (Y20) requires that pressure is built up in the system.

Description of function: Fan speed adjustment circuit

The fan speed adjustment electric motor M3 rotates clockwise or counterclockwise by means of switch S18 and relay K71 or K72.

Adjustments are only allowed while the fan is running.

Important!

The power supply of relays K71 and K72 depends on the threshing mechanism relay K63 (see corresponding section). Adjustments of the fan speed are possible only when switch S65 (Threshing drum / fan speed changeover) is set to "Fan".

Threshing drum speed indicator

If the threshing drum speed is to be displayed, switch S65 (Threshing drum / fan speed changeover) must be set to "Threshing drum". In this case, the threshing drum symbol (H48) is lighted and the corresponding signals from the threshing drum speed sensor are processed in indicator P3.

Fan speed indicator

If the fan speed is to be displayed, switch S65 (Threshing drum / fan speed changeover) must be set to "Fan". In this case, the fan symbol (H49) is lighted and the corresponding signals from the fan speed sensor are processed in indicator P3.

Hour meter indicator

When voltage from the branch K61/87 (generator) is applied at the hour meter P1, the hours worked are displayed.

Description of function: Grain tank unloading tube swing circuit

The grain tank unloading tube swing function is controlled by the multifunction handle module (A52).

With the road travel circuit unlocked, module (A52) is supplied with power.

The seat contact (Z5) must also be actuated.

Depending on the direction (swinging in or out), the switches (S87/S88) transmit an earth signal to the multi-function handle module (A52). Module A52 actuates the corresponding solenoid coil, i.e. grain tank unloading tube swing out (Y33) or grain tank unloading tube swing in (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.

Swing grain tank unloading tube time control

09/06

When one of the switches (S87 / S88) is actuated for more than 1.25 seconds, the Swing grain tank unloading tube function remains active for 30 seconds.

Actuating one of the switches (S87 / S88) one more time briefly stops swinging in/out of the grain tank unloading tube.

Description of function: Front attachment circuit

The following pre-conditions must be met for the front attachment drive to be switched on: - Road travel switch (S52) unlocked - Relay K60 energized - Main drive (threshing mechanism clutch) engaged (S25) - Seat contact (Z5) actuated

- Zero position S55

When touch sensor S55 is in zero position, pins 3+4 are open, pin 5+6 are closed.

- Front attachment ON

When actuating touch sensor S55 (pins 3+4 closed, pins 5+6 closed), earth is applied to solenoid coil Y88 – the front attachment is engaged.

The multi-function handle module (A52) switches in parallel via S55 (pins 5 + 6) and remains locked in so that the front attachment remains engaged even after releasing pushbutton S55 (neutral position).

Important! The earth supply of the front attachment clutch solenoid coil (Y88) depends on relay K78.

When the front attachment OFF switch (S54) is actuated, the multi-function handle module (A52) does not energize relay K78 any more.

- Front attachment OFF

After pressing pushbutton S55 (pins 5 + 6 open), the internal locking in the multi-function handle module (A52) is interrupted. The front attachment disengages.

Seat contact circuit

After leaving the operator's seat, all circuits depending on the seat contact are interrupted after approx. 5 seconds (front attachment disengages).

Reversing safety circuit

When engaging the front attachment, relay K79 is also actuated in parallel and cuts the earth supply to the front attachment reverse pushbutton S57. Reversing therefore is possible only with the front attachment disengaged.

Reversing circuit (hydraulic)

During reversing, the electric motor M24 is switched on by switch S57 via relay K62.

The master valve (Y77) is also actuated via the diode PCB (DO) in parallel with the solenoid coil (Y86) because this function requires that pressure is built up in the system.

Important!

Description of function: Raise/lower front attachment (manual)

Depending on the actuation of the raise/lower front attachment pushbuttons (S56 / S66), the corresponding solenoid coils (Y87 / Y85) are actuated via the multi-function handle module (A52) – the front attachment is raised or lowered.

The master valve (Y77) is also actuated via the diode PCB (DO) in parallel with the front attachment raise function (Y85) because this function requires that pressure is built up in the system.

Transverse control (manual) circuit

Voltage is applied to the solenoid coils Y67/Y68 as a function of the road travel switch S52. After actuation of switch S46, the required earth is connected either to solenoid coil Y67 or Y68.

The master valve (Y77) is also actuated via the diode PCB (DO) in parallel with the solenoid coils (Y67, Y68) because this function requires that pressure is built up in the system.

TIC Description of function: AUTO-CONTOUR function

MEDION

Electric system

1/2 AUTO-CONTOUR (CAC) includes the functions cutting height control and/or pre-set cutting height control.

The AUTOCONTOUR (CAC) module A8 is activated by actuating switch S11.

Important!

On machines with AUTO-CONTOUR, a module with the corresponding spare part no. must be used which is different from the CONTOUR system.

Cutting height control

The function "Cutting height control" is activated by actuating switch S12 in the module CAC A8.

In the cutting height control, both the sensors B3/B4 and/or potentiometer R1/R2 of the sensing bands on the cutterbar and the cutterbar spring prestress potentiometer R22 are active as actual values. The set value is defined by potentiometer R23.

Changes of the signal values are detected by module A8. Now the relevant solenoid coils of the individual functions (transverse control right/left and/or front attachment raise/lower) are actuated by module A8 until the set values and the actual values of the corresponding sensors / potentiometers are identical.

Pre-set cutting height control

The function "Pre-set cutting height control" is activated by actuating switch S13 in the module CAC A8.

When this function is selected, there is no active cutting height control.

The signal values of the feeder housing position (R8 – actual value) and pre-set cutting height control (R24 – set value) potentiometers are made identical by the relevant solenoid coils (raise/lower front attachment).

Emergency clearance

In the function "Pre-set cutting height control", the front attachment makes way by means of the transverse control as soon as a sensing band has ground contact (e.g. an obstacle). The front attachment must now be returned manually.

Learning the sensor values

The AUTO-CONTOUR module (A8) must be set to the programming mode for learning the sensor values and for programming the AUTOCONTOUR control response. This is done using the CAC main switch (S11).

Learning is necessary after replacing the AUTO-CONTOUR module (A8) or the sensors / potentiometers of the AUTO-CONTOUR system.

Programming values for AUTO–CONTOUR control response by R23

Engage the threshing mechanism and the front attachment.

Set the cutting height control potentiometer (R23) to the value desired for the AUTO-CONTOUR control response.

Keep the CAC main switch (S11) pressed for 3 seconds beyond the notch. Now the indicator lights H37 and H38 flash.

At the same time, the raise/lower front attachment solenoid coils (Y85/Y87) are energized by the multi-function handle module (A52).

Actuate the attachment completely until the cutterbar cylinder springs have been relieved. Keep the lower front attachment switch (S66) pressed in this position for another 30 seconds.

Actuate the raise front attachment switch (S56). Raise the front attachment completely. Keep the raise front attachment switch (S56) pressed in this position for another 30 seconds.

Position = 5 = Default value Position < 5 = More influence by cutterbar spring pre-tension potentiometer R22 (down grain, soft ground).

Position > 5 = More influence of sensor band sensors and/or potentiometers R1/R2 and B3/B4.

lDescription of function: CONTOUR function

The CONTOUR system includes the functions automatic ground pressure control and pre-set cutting height control. The automatic ground pressure control is controlled by relay K55 and the pre-set cutting height control by the Contour module A8.

Automatic ground pressure control

When relay K55 connects earth from pin 87 to switch Z73 (ground pressure), the cutterbar can be raised or lowered automatically, depending on the outside conditions.

Pre-set cutting height control

- ON

After actuating the main switch S11, earth is applied to pin 30 of relay K55 when the threshing mechanism is engaged. Voltage is applied to pin 86 of relay K55 (see diagram 20a) via the unactivated solenoid coils Y85/Y87 and via the diode PCB DI. When pushbutton S12 is actuated, earth is applied to pin 85 of relay K55 via the multi-function handle module (A52).

At the same time, the necessary earth is applied at the automatic ground pressure control switch Z73. Switch Z73 is coupled to the left-hand cutterbar spring. When the spring length changes, the earth applied to switch Z73 is connected to the corresponding solenoid valves Y85 or Y87.

The cutterbar is raised or lowered (see diagram 20a).

- OFF

Deactivating the CONTOUR function is possible in several ways.

Open switch S11; K55 drops out - Contour is deactivated.

Raise or lower the cutterbar manually; the corresponding solenoid coils Y85 or Y87 are actuated directly by S56 and/or S66, the cutterbar is raised or lowered. This changes the length of the cutterbar spring, switch Z73 connects earth to the other solenoid coil (Y87 or Y85). Both solenoid coils are actuated for a short period, the locking-in of K55 is stopped, K55 drops out – CONTOUR is deactivated.

The "Pre-set cutting height control" function is activated by actuating switch S13 in Contour module A8 via the multi-function handle module (A52).

The signal values of the feeder housing position (R8 – actual value) and pre-set cutting height control (R24 – set value) potentiometers are made identical by the relevant solenoid coils (raise/lower front attachment).

Important! On machines with CONTOUR system, a module with the corresponding spare part number must be used that is different from the AUTO-CONTOUR system. In case of machines with CONTOUR system, potentiometer R 23 in the operating panel exists, but has no function. An existing potentiometer R 22 on the cutterbar spring serves merely for indicating the spring pre-stress in the panel.

Description of function: Yield measuring

The yield measuring is based on flow rate measurement by the light barrier (B59/B60) inside the grain elevator, depending on transverse and longitudinal inclination of the machine. Based on these signals, the yield meter module (A21) calculates the yield and displays this information in terminal A30 via the CAN bus.

System calibration by entering the litre weight and by checking the values by counterweighing a defined grain quantity constitute important fundamentals for a precise calculation.

Humidity measurement

The measurements made by the humidity sensor (B61) are also displayed by the yield meter module (A21) in terminal A30 via the CAN bus, but are not used for calculating the gross weight.

Terminal A30 requires these measured values for calculation only for stating the net weight in order processing.

Fieldwork computer functions

The signals from sensors B10, B11, B15 and B16a are entered into the fieldwork computer module (BIF/CAB) A10 and processed there. This module transmits the established information data to terminal A30 via the CAN bus.

Description of function: AUTOPILOT function with sensor system

With the road travel activation unlocked and the threshing mechanism engaged, the AUTOPILOT module A 9 is supplied with power via main switch S10. Following the start signal from foot switch S9, the solenoid coils Y9/Y10 are actuated, depending on the signals from the touch sensors B7/B8. The steering position is controlled by wheel angle sensor B 6.

The master valve (Y77) is also actuated via the diode PCB (DO) in parallel with the solenoid coils (Y9/Y10) because this function requires that pressure is built up in the system.

For safety reasons, the AUTOPILOT function is interrupted immediately by the signal from overrider switch Z3 when the steering wheel is turned manually or after approx. 5 seconds after leaving the operator's seat, by means of seat contact Z5.

The centralizing switch R3 allows setting precise straight forward travel even when driving on slopes.

To allow quick steering reactions during AUTOPILOT operation, the hydraulic system is equipped with an accumulator. If the pre-stress of this accumulator drops to below approx. 135 bar, the oil pressure switch Z4 triggers the circulation shut-off valve Y77 until a charging pressure of approx. 160 bar has again been reached.

Settings on the module a b c d

- Steering signal right - Steering signal left - Malfunction indicator - Operation check

Potentiometers 1 - Steering angle:

At maximum steering angle by the system sensors, the steering cylinder stroke is set to 26-34 mm for both directions.

2 - Straight ahead travel:

Setting of straight ahead travel when centralizing switch is in neutral position.

3 - Response threshold:

The sensitivity of steering reactions is adapted to calm the system. * The potentiometers (1, 2, 3) are shown here in their basic position.

Description of function: Compressor-type air conditioner circuit

The electro-magnetic clutch of the compressor-type air conditioner only switches as a function of the actuated relays K75 and K68. In addition, a fan speed must be pre-selected.

Important!

09/06

The system is pressure-monitored by switches Z22 and Z23.

- The high-pressure switch opens at 24 bar and closes at 18 bar.

- The low-pressure switch opens below 2 bar and closes at 2.25 bar.

If the earth signal fails due to one of the two gas-pressure switches Z22 or Z23, the electro-magnetic clutch Y32 is disengaged. This malfunction is displayed by warning light H12.

Description of function:

Automatic air conditioner

Together with the cab fan speed controller module (A7), the automatic air conditioner module (A6) provides the complete temperature control inside the cab.

This involves both actuating the compressor-type air conditioner clutch solenoid coil (Y32) for the cooling compressor via relay K68 and switching the heater circuit on and off if required via the heater solenoid coil (Y109) until the set values are identical with the actual values of the corresponding sensors.

The two closed gas-pressure switches Z22/Z23 must supply relay K68 with earth in order to allow the function of the compressor-type air conditioner electro-magnetic clutch solenoid coil (Y32).

If the earth signal fails due to one of the two gas-pressure switches (Z22/Z23), the compressor-type air conditioner electro-magnetic clutch solenoid coil (Y32) disengages and this fault is displayed by the compressor-type air conditioner fault signal light H12.

The anti-icing device switch Z74 prevents icing on the evaporator.

econ operation

In this operating mode, the cooling compressor is not activated. The entire air conditioner control is realised by the heater and the fan.

REHEAT function

In this operating mode, the cooling compressor is permanently activated.

The ambient sensors (e.g. outside temperature sensor) is not considered here.

Activation is for a defined period of time (see also Operator's Manual).
