5.0 Threshold Alarms
The Alarm function must be activated every time the unit is powered on. To activate,
wait until the unit has cycled through its startup and is steadily displaying the
analyzer’s reading. Press the
On/Off and Prog buttons at the same time until an arrow
appears on the left side of the display.
Should the nitrogen reading exceed the threshold alarms (AL1 or AL2), the instrument
will go into alarm mode and activate the (optional) relay output (open collector max
100mA) and the audible alarm. The display will show the trespassed alarm and the
actual measured value. To stop the audible alarm, press any key. In this event the Pro
N
2
Alarm Analyzer will remain in alarm mode until the analyzed value goes below the
alarm.
The relay output typically is used to shut down the compressor. Nuvair can supply the
necessary components to adapt your compressor to the relay or provide them at the
time of install on a new compressor.
To deactivate the alarms, press the
On/Off and Prog buttons at the same time until
the arrow goes away.
