11.13 Pro CO Threshold Alarms
Should the Carbon Monoxide reading go over the threshold alarms (AL1 or AL2) the
instrument will go into alarm mode and will activate the (optional) relays output (open
collector max 100mA) and the internal buzzer. 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 Co 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.
11.14 Powering Off the Pro CO
At the home or gas reading screen, hold down the On/Off button for a couple of seconds.
The Analyzer will display “OFF” and then go blank.
11.15 Pro CO Factory Reset
In case it is necessary to reset the Pro CO Analyzer to the factory settings, power on the
Analyzer pressing at the same time for more than one second the “On/Off” and “Adjust”
buttons. On the display will appear “res” and the instrument will go to the reading page.
You will need to open the Pro CO analyzer and get the Values from the sensor for
inputting into the PRO CO analyzer before using.
In case of reset, the instrument will delete all the alarms settings, the full scale value, any
new conversion value of Carbon Monoxide sensor and of the gain factory. Before using
again the instrument, it may be necessary to program again the alarm values, the full
scale value, and the conversion value of Carbon Monoxide sensor and gain factor if
changed. All the analysis concentration shown on the display would be wrong. Wrong
Carbon Monoxide analysis may lead to death.
11.16 Pro CO Sensor Replacement
You should take note of your “Fsc” Number and “nA” Number before installing a new sensor.
The “Fsc” number is programmed into the Pro CO Analyzer at the “Fct” and “Fsc” setting.
This information will be used to program the Pro CO analyzer after the sensor is installed.
“Fsc” Number:
Na Number
