What it represents
A transition indication identifies a documented change between positions or states. A transition describes movement between documented states rather than a steady-state position. Its meaning depends on the source state, destination state and initiating event.
In a sequence or operating-state drawing, retain those state labels close to the transition. An electrical contact diagram still needs its own normal-state convention.
How to read it
- Define the states and the event that causes the transition in the diagram context.
- A transition annotation is distinct from a steady-state device symbol.
Information to show or reference
- Identify the associated device, circuit or diagram boundary.
- Define the states and the event that causes the transition in the diagram context.
- Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.
A distinction that matters
A transition annotation is distinct from a steady-state device symbol.
