L1 - Motor - True Or False Flashcards
A NOTC designation refers to an off delay timer?
False; to relays
Normally-open, timed-closed. Abbreviated “NOTC”, these relays open immediately upon coil de-energization and close only if the coil is continuously energized for the time duration period.
A time delay relay often includes both timed and instantaneous contact
True
Timed relays can provide anti-plugging protection for a reversible motor
True
A two wire cct provides low voltage protection
False
The 2-wire control circuit provides what is known as “low-voltage release.” In the event of a power failure, the magnetic motor starter will drop out.
A shading coil is not required for a DC voltage coil
True
A noto contact will be closed while timed-relay coil is energized
True
A 3-wire circuit incorporates a maintain contact
True
Limit switches detect travel
True
Limit switches are used in a variety of applications and environments because of their ruggedness, ease of installation, and reliability of operation. They can determine the presence, passing, positioning, and end of travel of an object.
