Alerts
indicate conditions or events which, while not preventing boiler operation, may nevertheless be of
interest in evaluating boiler performance or operating conditions. Examples include certain operator actions,
out-of-range configuration data, controller internal status reports (e.g. timers, counters, memory read/write
activity), and recycle events. Alerts require no operator acknowledgment and are for informational purposes
only.
The most recently occurring message (Lockout, Hold, or Alert) is displayed in the alarm banner on the
Overview screen (see
Figure 15
). Press this banner to access the Alert or Lockout History, where a list of
the most recently occurring Alerts/Lockouts can be viewed.
To obtain more information for a particular message, press that item in its respective history list. For Alerts,
burner cycle and hours of operation at the time of occurrence will be displayed. For Lockouts, in addition
to cycle and hours the screen will show on/off status of all interlocks at the time of the lockout. This
information can be used to help pinpoint the cause of a particular Lockout.
If the boiler is left unattended after a startup, the Alert/Lockout History can be consulted to determine
whether the boiler has been running normally or if operation has been interrupted due to a fault condition.
