## Symbol convention

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

This qualifier identifies an operator action applied to the associated mechanism.

## What it represents

This qualifier identifies an operator action applied to the associated mechanism. A manual mechanism can operate a switch, valve, latch or adjustment without having its own electrical supply. The qualifier tells the reader how an action originates, while the main symbol still identifies what the device does.
For a local operating station, connect the operation mark to the relevant device tag and contact references. This avoids reading the operator itself as another electrical load.

## How to read it

- Keep the qualifier linked to the device it operates rather than treating it as another electrical terminal.
- Manual operation is a mechanism attribute, not a normally-open or normally-closed contact state.

## Information to show or reference

- Identify the associated device, circuit or diagram boundary.
- Keep the qualifier linked to the device it operates rather than treating it as another electrical terminal.
- Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.

## Important distinction

Manual operation is a mechanism attribute, not a normally-open or normally-closed contact state.
