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
Lex-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 01a,
		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. „S25”) defines the connection.

- Numbers next to the circle (e.g. „1”) 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 seat contact switch Z5 (see circuit diagram 17a). The number next to the circle (e.g. 15) indicates the number of the circuit diagram on which another function depending on the seat contact is shown.

Designations

- Connectors (e.g. „M”, pin 9 and 17) .

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.
