🔍 Key Concepts

• Control vs. protection functions of a low pressure cut-out in refrigeration systems • Relationship between suction pressure and compressor operation • How a primary controller affects compressor cycling (on/off)

💭 Think About

• Ask yourself: does this device mainly keep a pressure constant, protect the compressor, or decide when the compressor should run? • Which of these choices describes a function that would cause the compressor to turn on after pressure rises and off after pressure falls? • Does a low-pressure cut-out modulate how much the compressor pumps, or does it simply allow or stop operation?

✅ Before You Answer

• Clarify the difference between maintaining a pressure vs. using pressure as a signal to start/stop equipment • Confirm whether a low-pressure cut-out can vary capacity or only act like an on/off switch • Verify that a primary controller in this context is the device that determines when the compressor is running or idle
