Chapter 20, Problem 1RQ

To determine

The operation of the circuit 2 if contact M1 did not close.

Expert Solution & Answer

Explanation of Solution

Consider the contact M1 is not closed and the current do not flow through the auxiliary contact and to the motor starter, then to the relay coil TR1. Thus, the motor 1 do not operate and the timer delay coil TR1 is DE energized. Since, the de-energized coil fails to close the contact of the TR1 the motor 2 do not starts.

Consider that the motor M2 is in the off state so the timer delay coil TR2 is not energized and the contacts of the TR2 is closed so the motor M3 fails to operate.

Thus, the case when the contact M1 are open the three motors M1, M2 and M3 do not work.
