What it represents
A handwheel qualifier identifies an operating mechanism moved by a wheel. A handwheel can change a mechanism position or adjust an associated element. The qualifier describes that manual interface, not a particular electrical output characteristic.
For an adjustment function, identify the controlled quantity and any position indication separately. For switching, retain the contact diagram and position table.
How to read it
- Keep the wheel indication tied to the operated mechanism and its position description.
- A wheel-actuated device can regulate or switch; the associated function must be stated.
Information to show or reference
- Identify the associated device, circuit or diagram boundary.
- Keep the wheel indication tied to the operated mechanism and its position description.
- Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.
A distinction that matters
A wheel-actuated device can regulate or switch; the associated function must be stated.
