Active alarms will cause the “Alarms” button in footer of the display to show the number of current alarms and flash the text. Selecting this button will navigate to the Alarms screen (Pg. 40) that displays the current alarms with their associated date/time stamp, alarm code, description, and action taken. By default, alarms for all the connected modules are shown, but can be sorted by module by selecting the “View Module:” drop-down box in the top center of the screen.
Selecting the “View” button of the associated active alarm navigates to the View Alarm screen (Pg. 41). This screen displays the alarm in additional detail and provides the option to disable the alarm by pressing the “Reset Alarm” button or examine the configuration of the alarm by selecting the “Go To Setup” button. This screen also has a “Sensor Snapshot” button to see a snapshot of the sensors for the given module at the time the alarm occurred.
If an alarm covers a single sensor value high or low trigger, selecting "View" will go to a graph showing the value of that sensor for the minute before the alarm.
Note: Most alarms are only active if the run signal is in the “Run” condition and the alarm timer on the home page has expired. If the Run Signal Trigger is not properly configured an alarm condition could be missed.
The alarms screen has a button “Alarm History” which brings up the Alarm History screen (Pg. 42) a list of all past alarms that have been acknowledged (cleared). The “< Prev” and “Next >” buttons at the bottom of the screen can be used to scroll through the list of past alarms. Clicking on “View” on an alarm will show the details for the given past alarm.
On the “View Alarm” page (Pg. 41) for either a currently active alarm or a past alarm has a “Sensor Snapshot” button that brings up the Sensor Snapshot page (Pg. 44) for that alarm. This page shows the value of enabled sensors on the alarmed module at the time of the alarm. The buttons “Back in Time” and “Forward in Time” can be used to scroll through sensor values for the minute before the alarm (for current alarms only).
If an alarm pulls up the alarm graph display instead, the sensor snapshot can still be downloaded by inserting a USB drive.
Note that the Alarm History page will show all past alarms that occurred on the EIM. The Alarm Snapshot data will only be saved on EIM versions 1.58 or newer, so some past alarms may not have sensor snapshot information. The one minute of snapshot data will only be available for active alarms. Once an alarm is reset, the history page will only show the snapshot for the moment the alarm occurred.
