Pneumatic timers are affected by variations in ambient temperature or atmospheric pressure.

The air flow switch is constructed from a(n) ____________________ micro switch.

The abbreviations TO and ____________________ are used with some control schematics to indicate a time-operated contact.

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?

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

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