SYMBOLS IN THIS WIRING DIAGRAM

LOGICAL SYMBOLS

The logical symbols are of four kinds: OR, AND, INV. (Inverter). PROCESS.
The circuit operation can be easily read by understanding these symbols.
OR
INV. (Inverter)

GRAPHIC SYMBOLS

SYMBOLS IN THIS WIRING DIAGRAM
In case of input to wither A or B, an output comes
out from C.
When a and B are off (0V), C is off (0V).
When either A or B is on (12V), C is on (12V).
This can be simply shown in the relay circuit on
the right-hand side.
In case on input to both A and B, an output comes
out from C.
When A and B are on (12V), C is on (12V).
When wither A or B is off (0V), C is off (0V).
This can be simply shown in the relay circuit on
the right-hand side.
In case of input to A, B is grounded.
When A is off (0V), B is on (12V).
When A is on (12V), B is off (0V).
This can be simply shown in the relay circuit on
the right-hand side.
PROCESS makes a simplified representation of
complicated functions of the circuit.
Functions mainly used:
1. Detection of signals
2. Conversion of signals
The process of the full transistor ignition control
unit is as shown in the right-hand figure.
