Layout of electric circuit

Following the circuit diagram layout, all electric circuits are shown in

diagrams

individual circuit diagrams. Some explanations are given below to

 

illustrate the layout.

 

 

 

Numbering of circuit diagrams

 

 

01...

- The respective numbering can be found on the corresponding cover

 

sheet and in the footer.

 

 

01a / 01b ...

- Depending on the machine no., the components fitted and the

 

country specification, there may be several individual circuit

 

diagrams for a given function.

 

 

 

 

 

 

 

 

Potentials

+30

 

 

 

 

 

- Main power supply (battery)

 

 

 

 

 

+15

 

 

 

 

 

- Ignition switch power supply (switched)

- Relay-controlled power supply

 

 

 

-31

 

 

 

 

 

- Earth

 

 

 

 

 

 

 

 

 

 

 

- Housing earth (external)

Connections

-The description provided inside the circle (e.g. “H44”) defines the connection.

-Numbers next to the circle (e.g. “1b”) describe the continuation of the cabling in accordance with the circuit diagram numbering which can be taken from the cover sheet or from the footer.

Designations

-Connectors (e.g. „X10”, pin 2– 1– 6– 5).

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

-Modules (e.g. “A23”)

The arrows identify the functional inputs and outputs according to the assignment table provided in chapter ZE.

Description of function:

 

 

 

Main power supply

Power supply from the tractor to the baler is via connector XV. On the

 

tractor, this prower supply should be protected by a fuse of 25 A max.

Potential + 15

This is switched by the main switch T 12 on the control box

 

(electronics +).

 

 

Potential K 90 / 87

Potential K 90/ 87 is a power plus protected against reverse polarity by

 

diode V10.

 

 

Overvoltage protection

VDR1 becomes conducting when overvoltage occurs. This smooths the

 

voltage peaks in the electronics circuit (+15 / -32).
