An alarm is an indication that an event that you have configured (for
example—Process Variable) has exceeded one or more alarm limits. There
are two alarms available. Each alarm has two setpoints. You can configure
each of these two setpoints to alarm on various controller parameters.
There are two alarm output selections, High and Low. You can configure
each setpoint to alarm either High or Low. These are called single alarms.
You can also configure the two setpoints to alarm on the same event and
to alarm both high and low. A single adjustable Hysteresis of 0.0% to
5.0% is configurable for the alarm setpoint.
Table 4-5 lists all the function prompts in the "ALARMS" Set Up group
and their definitions.
