Chapter 42, Problem 6RQ
Refer to the circuit shown in Figure 42–17. Assume that the motor is running in the forward direction. When the revers e push button is pressed, the motor continues to run in the forward direction. Which of the following could cause this problem?
- a. The normally open side of the reverse push button is not making a complete circuit when pressed.
- b. R contactor coil is open.
- c. The normally closed side of the reverse push button is not breaking the circuit when the reverse push button is pressed.
- d. There is nothing wrong with the circuit. The stop push button must be pressed before the motor will stop running in the forward direction and permit the motor to be reversed.
