Purge Valve

Low N2 measured upon completion of initial Perfect Purge purge cycle

Action:

  1. Check the N2 level % at the INS-PV (or INS-RA).
  2. If the N2 level % is below 82%:
    1. Check to ensure that ball valve is open to INS-PV unit. If ball valve is closed INS-PV cannot sense the nitrogen in the system. Open ball valve and press Refresh N2 on the INS-PV.
    2. Ensure the nitrogen generator is in Nitrogen Generating Mode. This can be checked by using a portable nitrogen analyzer. The N2 level % leaving the membrane should be 98% or greater. Note the nitrogen generator needs to be running for accurate nitrogen reading. Call technical support if nitrogen leaving membrane is not 98% or greater.
  3. If the N2 level % is above 90%:
    1. Check the DIP switch configuration for the sprinkler system. Ensure the correct size sprinkler system setting was selected for unit. See Programming Guide for configuration. The purge process may need to be repeated.
    2. Ensure the nitrogen generator is in Nitrogen Generating Mode. This can be checked by using a portable nitrogen analyzer. The N2 level % leaving the membrane should be 98% or greater. Note the nitrogen generator needs to be running for accurate nitrogen reading. Call technical support if nitrogen leaving membrane is not 98% or greater.
