Typical metal particle detector
Remove the cover from the detector.Note: Some engine oil will drain out of the particle detector when the cover is removed. Prepare to catch the engine oil in a suitable container. Clean up any spills with absorbent pillows or towels. Do not use absorbent particles to clean up the spills.Test Procedure
Ensure that the monitoring system is powered up.
Place an electrical conductor on a grid in the metal particle detector.If the particle detector is operating correctly, an alarm will be activated.
Remove the electrical conductor from the grid.
Place an electrical conductor on the grid of the metal particle detector and wait at least 5 minutes.If the metal particle detector is operating correctly, a shutdown will be activated.
Remove the electrical conductor from the grid.
Make sure that the monitoring system is powered up.Note: Steps 7 through 9 must be completed within 15 minutes in order to trigger an engine shutdown.
Repeat Step 2 and Step 3.If the particle detector is operating correctly, an alarm will be activated when the conductor is placed on the grid.
Repeat Step 2 and Step 3 a second time.If the particle detector is operating correctly, an alarm will be activated when the conductor is placed on the grid.
Repeat Step 2 and Step 3 a third time.If the metal particle detector is operating correctly, a shutdown will be activated.
Ensure that all conductors have been removed from the system.
Install the cover for the detector.
