For example, if the first display line is showing % O
2
values, and a high
alarm occurs, an up arrow will appear to the right of the O
2
value. If, for
example, you set alarm 3 for a high O
2
alarm and alarm 4 for a high/high O
2
alarm, and the O
2
value exceeds both the high and high/high alarm set
points, two up arrows will appear next to the O
2
value on the display.
Do the following to set your alarm set points.
1. Select Alarm Set Points from the Alarm menu.
Once you select the Alarm Set Points menu option, the system
alerts you that alarms 1 and 2 are reserved for the watchdog and
service alarms, and are therefore not software selectable. Press the
Enter key to continue to the configurable alarms.
You will be prompted to define the Alarm 3 set point value (this option
won’t appear if Alarm 3 is not set to activate based on a % O
2
reading,
but rather is set to activate based on the start of a calibration or verifica-
tion - see the “Select Function” section in this chapter for details):
Alarm #3= xx %O2
New Value?
2. Enter the Alarm 3 set point value, then press the Enter key (just press
the Enter key if you don’t want to change the current value).
You are then prompted to enter the Alarm 4 set point value:
Alarm #4 =xx %O2
New Value?
3. Enter the Alarm 4 set point value.
If you don’t have the combustibles option installed, you are done (press
the Cancel key to then exit this menu option). If you do have the com-
bustibles option installed, you are then prompted to enter the alarm 5 set
point value:
Alarm #5=xx yy
New Value?
where xx is the current value and yy is either PPM combustibles or %
combustibles, depending on the scale you are using (see the “Combus-
tibles” section in the Setup Key Chapter for details on setting combus-
tibles scale).
