Which of the following statements best describe the purpose of parameters?

One correct answer

  • To adjust the EPC 400 to the correct variables for each installation to ensure optimal performance.
  • To adjust the EPC 400 for different separator types and installations, to ensure optimum performance.✓ Correct answer
  • It makes adjustments very easy.
  • Part of the fashion in moving to more sophisticated electronics.
What is the purpose of these holes?

One correct answer

  • To prevent build up of pressure when the drain valve is closed.
  • To allow movement to minimise over-heating.✓ Correct answer
  • So there is always a flow through the small hole in the flow control disc to stop it getting blocked.
  • To allow air to be vented from the oil paring chamber.
Which statement best describes why a flow control disc can replace a set of gravity discs?

One correct answer

  • An ALCAP separator is a clarifier, and a clarifier does not have a gravity disc.
  • The small hole enables water to be drained off when the drain valve is open.
  • Normally the ALCAP separator runs as a clarifier, and when draining water, it is a purifier with a restricted broken water seal.
  • By keeping interface outside the disc stack, the water seal is less important, only one flow control disc required.
  • With the ALCAP the chance of having the interface into the disc stack is reduced because of the small hole in the flow control disc.
  • With the ALCAP we are not so concerned with the position of the interface, it can be outside the edge of the top disc. It is not necessary to change gravity discs to ensure correct interface position.✓ Correct answer
Which group of parameters may have to be adjusted for a different oil type?

One correct answer

  • Installation parameters
  • Service parameters
  • Process parameters✓ Correct answer
  • Timer parameters
  • All of them
Loss of Water Pressure to the Valve block will

One correct answer

  • Make system malfunction.✓ Correct answer
  • Will not affect the system.
  • Water pressure loss can be accommodated for some time.
