Textbook Question
Chapter 22, Problem 1SQ
Describe what is meant by sequence control.
Expert Solution & Answer
To determine
Describe the meaning of sequence control.
Explanation of Solution
Sequence control:
Sequence control is a method of control to activate all the elements in a sequence manner.
This type of control is necessary wherever the activation of an auxiliary component depends on the main components.
In this control method, the starters are connected in a system such that one motor cannot be energized until another one is in operation.
Applications:
- Using in the systems wherever auxiliary equipment is associated with main systems. For example: hydraulic and lubricating oil pumps.
- Using in conveyor systems (subassembly or main line).
Conclusion:
Thus, the meaning of sequence control has been explained.
