Alarms
The TrueBlend system contains alarms for each device in the system. There are three levels
of alarm severity, Information, General, and Shutdown. A single alarm may have a different
severity level based on which operating state the system is in. For example an empty hopper
alarm may be a General alarm when the system is stopped but it is a Shutdown alarm if the
system is running. Each alarm type and the severity assigned can be viewed and edited in
setup. To navigate tot the Alarms Setup section from the <Home> screen, press [More…] –
[Setup] – [System] – [Alarm].
The last 100 alarms are logged to the system memory and even after a reboot sequence, are
available for viewing. This historical log can be cleared by the user. The logged alarm list
has additional entries, indicating when the alarm became active, when it went inactive, as
well as when an alarm was acknowledged.
On the <Report> screen it is possible to generate reports that list either the active or logged
historical alarms. These reports can then be viewed away from the device.
To view the active or logged alarm lists, an operator can press the [Alarm] button located on
the lower left hand corner of the touch-screen. The color of the alarm button reflects the
level of the most severe active alarm. Touching this button will navigate the operator to the
active alarms screen. The logged alarm list can then be viewed by pressing the [Alarm Log]
button located on the <Active Alarm> screen.
Shutdown Alarm RedThis alarm severity indicates a critical condition and caused the line
to shut-down. This requires immediate attention.
Active Alarms
The <Active Alarms> screen is divided into two main sections. The (Alarms) section con-
tains the list of active alarms. The (Help) section contains context sensitive help information
for the currently highlighted alarm. Active alarms are alarms whose trigger condition is
actively occurring or that had occurred but have not yet been acknowledged. Active alarms
can be acknowledged, but as long as the trigger condition occurs, they will continue to
appear in the list. When the alarm condition is no longer occurring, and has been acknowl-
edged, it will be removed from the list.
The (Alarms) section appears along the left hand side of the screen. The alarms in the list
will appear color coded based on the severity of the alarm at the time it was triggered. If the
alarm condition is white, the alarm condition is no longer occurring.
