Vacuum Leak-Up Testing

 

 

A vacuum leak-up test will determine if the furnace is leaking at an acceptable low rate, as defined by the operator.  NOTE: The Vacuum Leak-Up Testing menu allows the user to configure test parameters.  However, to perform the actual test, a recipe that uses the VLUP_chk opcode must be created and run. 

 

Vacuum leak up event

The event number of the vacuum leak-up test can be assigned in Configurator and entered here.  This number will be used in recipes to perform the leak-up test.  0 will disable.  Press Edit to enter the number.

 

Max rate µ/hr

This is the maximum tolerable leakage rate of the furnace.  A recipe using the VLUP_chk opcode will use this number to determine if the test has passed or failed.

Press Edit to change the number.

 

Number of tests

Each leak test is evaluated as Pass, Fail, or Retry.  This parameter determines the number of times the controller will perform a vacuum leak-up test before the furnace is considered to have failed.  Press Edit to change.
