2. Interconnection Wiring Diagram of Parts
2.1 Instructions for the Use of the Interconnection Wiring Diagram of Parts
The symbols in the interconnection wiring diagram of parts 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 the signal.
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 the signal.
Represents a interconnection 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 the signal.
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
the signal.
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 the signal.
Represents a connection between lead wires.
Represents a connection between parts by tightening of a screw.
Represents a connection between "A" and "A".
24VDC
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).
