7.2. Normal Run/Standby Mode
“Running” mode is when the FPS-500 is producing nitrogen and supplies it to the storage tank. The
system will automatically enter “Standby” mode when the tank is fully pressurized (65-75 PSIG). It
will remain in “Standby” mode until the tank pressure falls 7-10 PSIG.
7.3. Controller Modes
This mode allows access to two features:
• Filter Change Reset - When a new FRP (Filter Replacement Kit) is installed, the 1000-hour filter
change time must be reset. After replacing the filter elements, press and hold the Filter Change

NORMAL RUNNING / STANDBY MODE (RUNNING -STANDBY)
“Running” mode is when the FPS-500 is producing nitrogen and supplying it to the storage tank.
The system will automatically enter “Standby” mode when the tank is fully pressurized (70 PSIG
+/-5 PSIG). It will remain in “Standby” mode until the tank pressure falls 7-10 PSIG.
To run the system in normal run mode:
1. Connect the correct power supply to the system.
2. Open the nitrogen generator’s 3-way outlet ball valve (lower left side of the cabinet) to nitrogen
out position.
3. On the nitrogen tank, open the gas inlet and outlet ball valve.
4. Push the on/Off toggle button on the upper left control panel to the “On” position (up) and the
system will automatically turn on and start filling nitrogen to the storage tank.
