# STE 110 - Vacuum Pumps, Cycles & Controls

**Course Credits:** 3

**Program:** Steam Sterilizer Repair Technician Certificate

## Course Description

This course, STE 110, provides an in-depth exploration of vacuum generation, cycle dynamics, and control systems integral to steam sterilization. Students will gain a foundational understanding of both pre-vacuum and gravity displacement sterilization cycles, including their operational principles and applications. Key topics include the theory and practical application of water-ring vacuum pumps, detailed analysis of cycle charts, and the architecture and programming concepts of Programmable Logic Controllers (PLCs) as they relate to sterilizer operation. The course also covers the principles and calibration of various pressure and temperature sensing technologies. Emphasis is placed on vendor-neutral technical principles, safety protocols, and systematic troubleshooting methodologies essential for biomedical equipment service technicians.

## Learning Outcomes

Upon successful completion of this course, students will be able to:

*   Differentiate between gravity displacement and pre-vacuum sterilization cycles, identifying their respective advantages and limitations.
*   Explain the operational principles, components, and maintenance requirements of water-ring vacuum pumps.
*   Interpret steam sterilizer cycle charts, identifying critical phases and potential anomalies.
*   Describe the fundamental architecture and function of Programmable Logic Controllers (PLCs) in sterilizer control systems.
*   Analyze the principles of operation for common pressure and temperature sensing devices used in sterilizers.
*   Apply systematic troubleshooting techniques to diagnose common issues related to vacuum systems, cycle execution, and control logic.
