Alarm Set Points
Set alarm limits. Use the
Alarm Configure
menu option to define whether
these limits represent high or low alarms, although certain restrictions
apply (See the “Alarm Configure” section later in this chapter for further
help on defining high/low alarms).
Oxygen, combustibles, and methane alarms are disabled during cali-
bration cycles.
If an alarm triggers, an up or down arrow (depending on whether a high
or low alarm) will appear to the right of the process reading on the dis-
play. 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.
Defining alarm set point
1. From the
Alarm
menu, select
Alarm Set Points
.
Once you select the Alarm Set Points menu option, the system
alerts you that Alarms 1 and 2 are reserved for the watchdog and ser-
vice alarms, and are not software selectable. Press Enter 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 set to activate based on the start of a calibra-
tion or verification - 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
Enter
(just press
Enter
if
you don’t want to change the current value).
You are prompted to enter the Alarm 4 set point value:
Alarm #4= xx %O2
New Value?
