## Symbol convention

Convention: IEC
Form: Emergency-operation qualifier
Autodesk IEC-60617 Symbol Preview — Operating-device and function qualifiers; vendor family reference, not certified IEC geometry or database identifier.

An emergency-operation qualifier marks the documented emergency actuation role.

## What it represents

An emergency-operation qualifier marks the documented emergency actuation role. Emergency operation describes the role assigned to an action in the controls design. It does not reveal every device that stops, the retained services or the restart sequence.
Use the shutdown cause-and-effect document to connect the actuator with its actual outputs. The circuit must still identify contacts, monitored feedback and reset interfaces.

## How to read it

- Cross-reference the shutdown function, reset method and affected equipment in the controls documentation.
- The qualifier is not a complete emergency-stop safety circuit.

## Information to show or reference

- Identify the associated device, circuit or diagram boundary.
- Cross-reference the shutdown function, reset method and affected equipment in the controls documentation.
- Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.

## Important distinction

The qualifier is not a complete emergency-stop safety circuit.
