Figure 7-2 In the accompanying figure, when the START button is pressed, current flows through ____________________ coil.

Figure 10-3 Two circuits that employ a control relay to provide jogging are shown in the accompanying figure. In both these circuits the control relay provides the ____________________ contacts, not the M starter.

The on-delay relay is often referred to as DODO.

In a three-wire start/stop motor control circuit, the Start Button can be wired normally open or normally closed. For the circuit to operate properly, the Start Button should be wired_____________________.

Figure 10-4 The accompanying figure shows a jogging circuit for a forward-reverse control. What are normally closed F and R auxiliary contacts used for?

Figure 15-6 In the accompanying diagram, the circuit is designed to control the operation of a(n) ____________________.

Timer relays are similar to other control relays in that they use a(n) ____________________ to control the operation of some number of contacts.

In a circuit in which three motors turn off in sequence, an overload on any one motor will not have an effect on the other motors.

Figure 8-2 Based on the accompanying figure, what happens to the three load contacts connected between the three phase power line and the motor after either START button is pressed?

The ____________________ gauge is ideal for measuring the level of turbulent, aerated, solids-laden, viscous, corrosive fluids.
