What it represents
This qualifier identifies an operating mechanism driven by a motor. The motor is an operating mechanism for another device, rather than necessarily the main load shown on the power diagram. A motor-operated switching device has power contacts, a drive circuit and position information.
Show those interfaces through device tags and cross-references. The operating qualifier should remain attached to the switching function even if the motor control circuit appears on another sheet.
How to read it
- Cross-reference the drive supply and the operated device's position/control scheme.
- A motor-operated switch still needs its own electrical switching function and interlock information.
Information to show or reference
- Identify the associated device, circuit or diagram boundary.
- Cross-reference the drive supply and the operated device's position/control scheme.
- Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.
A distinction that matters
A motor-operated switch still needs its own electrical switching function and interlock information.
