FIGURE 11: ENTERING ALARM #2 SET POINT
When you have finished entering your value for alarm #2, pressing F1 brings up the original
page 2 of the CONFIGURATION MENU (fig. 1). Pressing F4 brings the first page of the
CONFIGURATION MENU and pressing F4 again brings back to MAIN MENU.
The values you enter must be in ppm. You may enter any value from 0 to 100 ppm, for any
alarm. Alarm #1 may have a set point higher or lower than alarm #2 and vice versa.
The digital contact output will open when the ppm value is equal or higher than the set point
value. The contact will close when the actual ppm value will go under the set point minus
0.1 ppm. This hysteresis will avoid oscillation.
