Wiring Diagrams 10-15
Notations Used in Wiring Diagrams
The symbols in the interconnection wiring diagram are described below. Note that the
description of general symbols is omitted.
Symbol Description
Represents an interconnection between parts using
wiring harness or wire, and indicates its signal name/
contents. The arrow “>” or “<” on the line represents the
direction of signal flow.
Represents an interconnection between parts using
wiring harness or wire, which differs according to the
specifications, and indicates its signal name/contents.
The arrow “>” or “<” on the line represents the direction
of signal flow.
Represents a connection between parts using a
conductive member such as a plate spring, and
indicates its signal name/contents. The arrow “>” or “<”
on the line represents the direction of signal flow.
Represents a function and a logical value (High (H) or
Low (L)) of a signal when the function is activated. The
voltage indicates a value when the signal is High. The
arrow indicates the direction of signal flow.
Represents a function and a logical value (High (H) or
Low (L)) of a signal when the function is in a detectable
state. The voltage indicates a value when the signal is
High. The arrow indicates the direction of signal flow.
Represents a connection between lead wires.
Represents a connection between parts by tightening of
a screw.
Represents a connection between “A” and “A”.
24 VDC
The DC voltage indicates an approximate value
measured when the negative side is connected to a
signal ground (SG).
Indicates a signal ground (SG).
Indicates a frame ground (FG).
