SYSTEM OPERATION
7.1 GENERAL
The nitrogen generator uses valve sequencing to produce nitrogen. The design meets specications
of a re protection system. Consult with South-Tek System for written approval before performing
any eld changes or customization. Unauthorized changes void all warranties and may cause
damages or malfunctions to the system.
This section describes the major control functions and instrumentations associated with the
nitrogen generators. All programs are proprietary and password protected from the factory. Do
not alter any controls or instrumentations. Changes without South-Tek Systems’ written consent
voids the performance specications.
Note: This section does not include the controls for supporting equipment, such as the
compressor and dryer. Consult the original manufacturer’s manual for further information.
7.2 NORMAL RUN/STANDBY MODE
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 lling nitrogen to the storage tank.
Once the nitrogen storage tank reaches approximately 70 PSIG, the system will turn go into
standby mode. No need to manually valve or power anything off. The system will return to the
normal run mode when the storage tank pressure falls to approximately 60 PSIG.
Note: Install the nitrogen generator per “Section 5: Product Installation” and perform the
startup procedures in “Section 8: Startup Procedures” before performing normal operations.
