Cooper SMP 4 - Configuring Alarm Inputs

SMP Gateway User Manual • 129
 change how time information is displayed in the various pages;
 set up an alarm buzzer to warn the operator of alarm occurrences.
The following sections explain all these steps in details.
16.2.1 Configuring Alarm Inputs
Alarms are the core of the Annunciator. You can use the Annunciator to display real-time values
or to perform control operations, but its most distinctive feature is the display and handling of
alarms.
Before configuring the various pages, you must configure the conditions that will trigger alarms,
which are called the alarm inputs. The Annunciator supports alarm inputs from analog inputs and
binary inputs. For analog inputs, alarms can be triggered when their value goes beyond a given
threshold. For binary inputs, alarms can be triggered when their state changes.
To define alarm conditions for an analog input, proceed as follows:
 In SMP Config, from the tree view, expand the Alarms branch to reveal the Analog Inputs
branch.
 Select the Analog Inputs branch.
 In the right pane’s grid, under Name, type the name of an analog input for which you want to
define the alarm conditions.
Note: The same subscription feature that was available to configure slave protocols can
be used instead of typing names. This is explained a bit further in this section.
 Under Alarm Level, select a severity level for this input’s alarms.
 Under Low Threshold, specify the value under which an alarm will be triggered for this
input. For example, if you specify a low threshold value of -13.1, an alarm will be triggered if
the input’s value becomes smaller than -13.1.
 Under High Threshold, specify the value over which an alarm will be triggered for this input.
For example, if you specify a high threshold value of 125.7, an alarm will be triggered if the
input’s value becomes larger than 125.7.
 Under Deadband, specify how much the value must go beyond the low or high threshold to
trigger an alarm. For example, if you set the deadband to a value of 5.0 and the high threshold
to a value of 125.5, an alarm will be triggered if the input’s value becomes larger than 130.5.
Note : This Deadband setting is different from the one found in the configuration of
master protocols, used to determine whether a value should be reported, or not,
to slave protocols through RTDX.
