What is the sequence of operation in Figure 22–2?

Chapter 22, Problem 4SQ, What is the sequence of operation in Figure 222? Fig. 222 Auxiliary contacts (or interlocks) used

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

To determine

Explain the sequence of operation in the control circuit of Figure 22-2.

Explanation of Solution

Sequence control:

Sequence control is a method of control to activate all the elements in a sequence manner.

This type of control is necessary wherever the activation of the auxiliary component depends on the main components.

In this control method, the starters are connected to the system as one motor cannot be energized until another one is in operation.

The sequence of operation:

Refer to Figure 22-2 in the textbook, the three motors M1, M2, and M3 are connected in an automatic sequence control operation and all three motors will come into operation in the pre-determined order.

Motor M1 is started by pressing the start button, and the second motor is connected through the maintaining contacts of the first motor...
