7 - 3Chapter 7 Wiring Diagrams and Signal Information2. Interconnection Wiring Diagram of Parts2.1 Instructions for the Use of the Interconnection Wiring Diagram of PartsThe symbols in the interconnection wiring diagram of parts are described below.Note that the description of general symbols is omitted.Symbol DescriptionRepresents an interconnection between parts using wiringharness 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 wiringharness or wire, which differs according to the specifications, andindicates its signal name/contents. The arrow ">" or "<" on the linerepresents the direction of the signal.Represents a interconnection between parts using a conductivemember such as a plate spring, and indicates its signal name/contents. The arrow ">" or "<" on the line represents the directionof the signal.Represents a function and a logical value (High (H) or Low (L)) ofa signal when the function is activated. The voltage indicates avalue when the signal is High. The arrow indicates the direction ofthe signal.Represents a function and a logical value (High (H) or Low (L)) ofa signal when the function is in a detectable state. The voltageindicates a value when the signal is High. The arrow indicates thedirection 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 whenthe negative side is connected to a signal ground (SG).Indicates a signal ground (SG).Indicates a frame ground (FG).
