Alarms Set Up Group

Introduction
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 to 100% is configurable for the alarm
setpoint.
See Table 2-4 in the Installation section for Alarm relay contact information.
The prompts for the Alarm Outputs appear whether or not the alarm relays are physically
present. This allows the Alarm status to be shown on the display and/or sent via
communications to a host computer.
