3. READING CIRCUIT DIAGRAMS
The circuit diagram is intended to show the
various circuits in the simplest way possible.
Symbols are used to do this.

1. “1000” and “1010” is shown at the top left of
the diagram.
These stand for:
1000 = supply before ignition.
1010 = supply after ignition.
2. “M” is shown at the bottom left of the
diagram.
This stands for:
M = earth connection.

3. To make it easier to find your way around
the circuit diagram, a “search bar” is
included at the bottom, which contains
numbers.
These numbers are called location
numbers.
In the legend to the circuit diagram, the
description of the basic code (ECN) is
followed by the relevant location number.
This means that a specific component can
immediately be located in the diagram.
4. There is an arrow above location numbers
60, 63, 64, and 68 in the diagram example.
Below this arrow is a number. This number
refers to the location number on the search
bar where you can find the relevant wire
number.
5. Beneath the “M” (earth connection) line are
found the “NC” codes relating to relay
G154, the “CO” codes relating to relay
G107, and “NO” codes relating to relay
G000.
These codes stand for:
NC = normally closed (= break contact)
CO = change over (= changeover contact)
NO = normally open (= make contact)
These contacts can be found at the location
numbers shown beneath the codes “NC”,
“CO” and “NO”.
At the relay contacts shown in the diagram,
you will also find the location numbers
indicating the relay coil locations.
6. In the circuit diagram, you will find the basic
codes (for example, E002). What these
codes stand for can be found in the legend
to the relevant circuit diagram.

7. If the wire numbers remain unchanged,
these will not be repeated in the circuit
diagram.
For example, in the sample diagram, wire
1101 is connected to connection point 87 of
relay contact G107, but also to connection
point 2 of component C622.
Wire 2100 (at location number 64) is
connected to connection point 30 of relay
G154, but also to connection point 85 of
relay G000 etc.
