2.4 Alarms The accQcomm has eight programmable relays for triggering
alarms based on one or two user-defined conditions (i.e., flow
rate, level, velocity, etc.). To program alarms, click the Alarms
tab.
Define the conditions by using the pull-down menus to select the
instrument (flow meter), parameter (level, flow, etc.), comparator
(>, <, ==, >=,<=), and value (Figure 2-7). For a list of all available
alarm parameters, and their definitions, see Table 2-2.
To use two conditions to activate an alarm, use the pull-down
menu between Condition 1 and Condition 2 to select AND or OR.
To use only Condition 1, select N/A.
To set an alarm to remain activated regardless of changes in
data, check the “Latching when triggered” box. To clear an alarm,
select the alarm and click the Clear Selected button.
In the example in Figure 2-7, an alarm will be permanently trig-
gered if the flow reverses.
