4.2. Alarm Setting (AL 1 & Al 2)
1.) Press the Prog button until the display reads “Pr”, then “AL1”. After a second the
display will show the current value of “AL1” CO PPM setting.
2.) The blinking digit shows the cursor position.
3.) Press the Prog button to increase the value (from 0 to 9)
4.) Press the Adjust button to cycle the cursor through the digits.
5.) To complete your entry and save the CO PPM value, press the On/Off button. You
will then move to the “AL 2” programming view.
6.) Repeat steps 3 through 5 to modify and save the “AL 2” CO PPM desired value.
7.) Once programming of “AL 2” is complete, press the On/Off button repeatedly until
the next desired program page is displayed or the end screen appears.
4.3. Full Scale Value Setting (FSC)
On the “FSC” page you can change the analog full scale value. It is not necessary to
modify this value unless a new sensor is installed. This is the Carbon Monoxide
concentration corresponding to 20 mA on the analog output. 4mA is the value at 0 ppm of
Carbon Monoxide. When installing a new sensor, input the “Fsc” value displayed on the
new sensor here AND in the “Fct” value.
1.) Press and hold the “Prog” button to access the program pages, then release the
button.
2.) Press the On/Off button to cycle through the settings until you reach the “FSC”
view.
3.) The blinking digit shows the cursor position.
4.) Press the Prog button to increase the value (from 0 to 9)
5.) Press the Adjust button to cycle the cursor through the digits.
6.) To complete your entry and save the FSC value, press the On/Off button
repeatedly until the next desired program page is displayed or the end screen
appears.
7.) This procedure is used ONLY when a new sensor has been ordered from
Nuvair and is ready to be installed.
