System Power Loss
In the event of a system power loss, all programmed information in the nitrogen generator is stored in
the nitrogen generator and the nitrogen generator will automatically restart once system power is
restored.
• Where Standard Vents are installed, the system will automatically return to Nitrogen Inerting
Mode or Supervisory Gas Mode, depending on which mode the nitrogen generator was in when
the power loss occurred.
o If Standard Vent ball valve is open (Nitrogen Inerting Mode), then the ball valve needs to
be manually closed upon completion of the fourteen (14) day DPNI process. The air
compressor and nitrogen generator will automatically transition to the Gas Supervisory
Mode.
• Where SMART vents are installed, the system will automatically return to the Supervisory Gas
Mode. When the system power loss is during the fourteen (14) day DPNI process, the DPNI
process will need to be reinitialized.
o Press the “Vent” button on the SMART vent control box which energizes the solenoid on
the SMART vent.
o The nitrogen generator and compressor will automatically cycle on operating in the
nitrogen inerting mode.
o Upon completion of the fourteen (14) day DPNI process, the vents automatically close
and the air compressor and nitrogen generator will automatically transition to the Gas
Supervisory Mode.
• Where AdvancedIQ vents are installed, the AdvancedIQ Vent Controller will automatically return
to the sequence prior to the loss of power.
