Referring to the diagram in Figure 22–2, explain what will happen if the motor that is operated by coil “M” becomes overheated.

Chapter 22, Problem 2SQ, Referring to the diagram in Figure 222, explain what will happen if the motor that is operated by

Fig. 22–2 Auxiliary contacts (or interlocks) used for automatic sequence control. Contact (M1) energizes coil (M2); contact (M2) energizes coil (M3).

To determine

Analyze the effect in the circuit (Figure 22-2), when the motor is operated by coil “M” becomes overheated.

Explanation of Solution

Refer to Figure 22-2 in the Textbook, three motors M1, M2, and M3 are connected using sequence control operation, in which all three motors come into operation in a pre-determined order. In the figure, note that the overload contacts of all three motors are connected in series...
