## Symbol convention

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

A timed-operation qualifier identifies operation influenced by the documented timing function.

## What it represents

A timed-operation qualifier identifies operation influenced by the documented timing function. A timing relationship describes when an action follows an initiating event. It does not decide whether the timing continues after the input disappears or how the function resets.
Document the input transition, the timed output and the intended timing mode. The main contact or actuator representation still supplies the resulting state.

## How to read it

- State the trigger, timing mode and reset condition separately.
- A generic timing indication does not distinguish on-delay, off-delay or pulse operation.

## Information to show or reference

- Identify the associated device, circuit or diagram boundary.
- State the trigger, timing mode and reset condition separately.
- Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.

## Important distinction

A generic timing indication does not distinguish on-delay, off-delay or pulse operation.
