Potter IntelliView® Troubleshooting

Purge Valves

Low N2 measured after initial IntelliDry purge cycle completed successfully

Issue: The INS-PV measured nitrogen level is below 98%.


  1. Check to ensure that ball valve between INS-PV and sprinkler system is open.
  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.
