Terms in this set (26)

one
No more than ____ load should be placed in any circuit line between L1and L2.
parallel
Loads must be connected in _____ when more than one load must be connected in the line diagram.
series,parallel
Two control devices can be connected in ____ or ____ to control a coil in a magnetic motor starter.
pilot lights
_____ signal an operator that any one of a sequence of events may be taking place.
simple
The dashed line method works well when the control contacts are close together and the circuit is relatively ____.
Complex
The numerical cross-reference method is used on ____ line diagrams.
signal
All control circuits are composed of ____, decision, and action sections.
mechanical
The signal condition can be manual, _____, and automatic.
Signal
The _____ accomplishes no work by itself; it merely starts or stops the flow of current in that part of the circuit.
Decision
The ____ of a circuit adds, subtracts, sorts, selects, and redirects the signals from the control devices to the load.
Action
In most cases it is the operating coil in the circuit that is responsible for initiating the _____.
AND logic
In ____, logic is used in industry when two NO push buttons are connected in series to control a solenoid, The load is ON if both of the control signal contacts are closed.
OR logic
In ____, logic is used in industry when an NO push button and an NO temperature switch are connected in parallel. The load is ON if any one of the control signal contacts is closed.
NOT logic
In ____, the load is ON only if the control signal contacts are closed. That has an output if the control signal is OFF.
NOR logic
_____ is an extension of NOT logic in which two or more NC contacts in series are used to control a load.
NAND logic
_____ is an extension of NOT logic in which two or more NC contacts are connected in parallel to control a load.
memory
Auxiliary contacts are added to provide ______ to circuits with pushbuttons. circuits are also known as holding or sealing circuits.
AND gate
An ____ is a device with an output that is high only when both of its inputs are high. gate is a universal building block of digital logic
OR gate
An ____ is a device with an output that is high when either or both inputs are high.
NAND gate
A ____ is a device that provides a low output when both inputs are high.
NOR gate
A ____ is a device that provides a low output when either or both inputs are high.
digital
An example of a(n) ____ process is a standard light switch that has only two positions: fully on or fully off.
dual in-line
Integrated circuits range in shape and size and include mini-DIP, ____, and flat-pack.
Jogging
____ is the frequent starting and stopping of a motor for short periods of time.
dead short
A(n) ____ is a short circuit that opens the circuit as soon as the circuit is energized or when the section of the circuit containing the short is energized.
AND logic
In ____, logic is used in industry when two NO push buttons are connected in series to control a solenoid, the load is ON if both of the control signal contacts are closed.
