Standard Controls and Instrumentation Overview
Each of our three types of generators, (Tank Mount, Cabinet, and Skid Mounts) all comes standard with
certain controls and instrumentations. This section describes the function of the major controls and
instrumentations associated with our standard nitrogen generators. Do not attempt to alter any controls or
instrumentations; any changes without the consent from South-Tek Systems will void the performance
specifications unique to your system.
Controls for supporting equipment, such as the compressor and dryer, are not included in this section.
Please consult the original manufacturer’s instructions for further information.

Power Switch/Power Light Indicators
The power switch is built into the Unitronics Touchscreen located in the upper left corner. It is the main
switch that controls powering on the nitrogen generator. The “Green Indicator” is lit when the unit is “ON”,
and the “Red Indicator” indicates “OFF”.
Touching the indicator for 2 seconds will manually change the states from ON/OFF position. A manual stop
will stop the PSA cycling. Nitrogen production will stop; airflow flow from optional air receiver does not
need to be stopped as the Nitrogen Generator will internally stop the delivery of airflow.
The PSA System Status can be viewed in the lower left corner. The “Green Run” indicates system operation,
the “Red Stop” indicates a manual stop, and the “Amber Standby” indicates the system in standby mode. The
“Standby Mode” is automatically programmed to enter the standby state once Nitrogen Storage Pressure is
