Answer the following statement(s) true (T) or false (F)
1. Two-wire motor control circuits are extremely complex motor control circuits.
2. Two-wire motor control circuits are called two-wire because there are only two control circuit wires between the motor starter and the control device(s).
3. Pilot devices control the motor starter control coil.
4. A pilot device is the term given to any two-wire control circuit component that mechanically closes and opens its control contacts, depending on the state of the medium it is measuring.
5. Two-wire control provides both no-voltage drop-out protection, or low-voltage drop-out protection.
