Exam 11: Motor Control Circuit Ladder Diagram Documentation

_______________ switches have the purpose of physically sensing the presence of different mediums.

The control circuit operating voltage is determined by the voltage ____ of the motor starter contactor control coil.

____ are drawings that represent or stand for some material object to derive its meaning or purpose.

The ____ is designated by a straight vertical stem with no arrow on it.

____ numbers or labels that the manufacturer has put on the component terminals facilitate connecting it in the circuit correctly.

Circuit input components are called ____ components.

_______________ are designated with what is sometimes called a double-question mark design symbol, next to the symbol for a normally closed set of contacts.

____ coils are wired in the control circuit, and when energized create the magnetic flux to actuate the armature of a magnetic relay or contractor.

Describe at least two concepts that can be applied when numbering the wires on the ladder diagram of a motor control circuit?

The ____is designated by the vertical stem, either straight or bent and capped with an arrow.

____ provide a delayed action changing operating states of the contacts associated with its control coil.

Switch and relay input contacts in the ladder diagram electrical control circuit are often configured to implement _______________ logic expressions that determine the logical operation of the control circuit.

All _______________ are labeled the same as the control coil by which they are actuated.

_______________ numbers can also help the troubleshooter follow the logical operation of the motor control circuit, without trying to trace control circuit wires through raceways and junction boxes.

Circuit output components are called ____ components.

The term _______________ determines how many different electrical circuits may be conducted through and controlled by the switch.

What is the purpose of reference documentation?

____ are used to provide a visual indication for an operator to verify that a certain operation is either energized or de-energized.

It is not uncommon to find motor control circuit wiring to start with the number ____ label.

A continuous dotted line indicates a(n) _______________ linkage between the contacts that the dotted line goes between.
