🔍 Key Concepts

• Follow the control circuit in Figure B from L1 through the man-stop-auto switch in the MAN position to see what devices are in series with the motor starter coil M. • Compare what changes when the switch is in MAN vs AUTO, especially the role of the pressure switch (PS) contacts 2–3. • Check how the disconnect switch (DS) and overload (OL) contacts affect power to the motor and whether they can be bypassed.

💭 Think About

• When the selector is in MAN, which contact (A or B) closes, and what does that do to the path feeding the M coil? • In that MAN path, is the pressure switch PS still in series with the coil or is it bypassed? • Can the motor run if the disconnect switch DS is open, or if an overload trips open the OL contact in the control circuit?

✅ Before You Answer

• Verify which devices are still in series with the M coil in MAN (look carefully at DS, OL, and PS). • Confirm whether the pressure switch PS is part of the control path in MAN or only in AUTO. • Make sure you understand that an open disconnect switch (DS) removes line power from the entire controller, regardless of the control switch position.
