What it represents
A clutch qualifier identifies a selectively coupled mechanical relationship. A clutch provides a selectable mechanical relationship between driving and driven elements. Its engaged and disengaged conditions can influence movement without interrupting an electrical supply.
Name the two coupled elements and cross-reference the actuation and position feedback. Mechanical coupling does not imply that the elements share one electrical circuit.
How to read it
- Name the driving and driven elements and the coupling control.
- Mechanical engagement does not mean electrical continuity between the elements.
Information to show or reference
- Identify the associated device, circuit or diagram boundary.
- Name the driving and driven elements and the coupling control.
- Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.
A distinction that matters
Mechanical engagement does not mean electrical continuity between the elements.
