10. Basic Timer Control: On-Delay and Off-Delay

A(n) ___________ relay is a type of control relay that moves its contacts to a new state after a predetermined time has elapsed

On-delay

The three basic components of a time-delay relay are the coil, the contacts, and the __________ mechanism

Timing

Common timing mechanisms include pneumatic timer, ______ timers, and motor-driven timers.

Solid - state

The two basic operating modes for a time - delay relay are on-delay relay and

off-delay

To avoid overheating, it is recommended that a motor be ________ when it is started.

Unloaded

A(n)_______ timer relay causes its contacts to change to their energized state as soon as the coil is energized.

Off Delay

An off-delay timer's contacts are in their __________ state while the timer is timing

energized

An off-delay timer's contacts are in their __________ state as soon as the preset time is reached

normal

For each distinct operation that takes place in a time-driven operation, a(n) _________

must be assigned.

timer

N.O.T.O. stands for normally-open-timed-_________.

Open

Timer relays perform the same function as _________ relays except they move their contacts to their energized state after a present time delay.

Control

A contact is _________ if it shows zero resistance in both the energized and de-enerized state

Shorted

A solid-state timer _________ be tested out of circuit

Cannot

To test a solid-state timer, you need to supply power and observe the ____________.

Contacts

A(n) __________ test means looking for loose or broken connections with power removed from the circuit

Mechanical
