Shutdown and Alarms page
Selecting this page takes the user to the page depicted in Figure 13.0. The top area of the
page is used to post shutdowns, and the lower part of the page is used to post alarms.
Figure 13.0 Shutdowns and Alarms Page
When the engine is running, the Active Shutdown will show “No Shutdowns.” If something
occurs that is serious enough to generate a shutdown such as overspeed or signal loss, a
message to this effect would immediately post in this area on the screen. This event is also
saved and time stamped. After the engine comes to a stop, the alarm message will remain
posted until the engine is restarted, at which time the message will automatically clear. There
is no need to cycle power or press any button to reset shutdowns. If the engine is shutdown
normally, for example, the fuel is cutoff, the Active Shutdown would show normal shutdown,
and it would be saved and time stamped below the Active Shutdown line.
The Alarms include some shutdowns as well as detected fault conditions that are not serious
enough to cause a shutdown but should be addressed before the problem becomes more
serious. The non-shutdown alarms include ignition diagnostics, 4/20 mA input errors, PIP
counts not perfect but within acceptable limits and others. When an alarm occurs the Alarm
relay will come on, the Alarm Relay LED indicator on the Operator page will turn red as well as
the LED indicator on this page.
When an alarm occurs the user has several options:
1. Leave the Alarm Relay on
2. Press the Alarm Acknowledge button which turns off the Alarm Relay
3. Press the Clear Alarm Button
Pressing the Alarm Acknowledge button will turn off the Alarm Relay, but the Alarm will still
remain posted on the page. If a new alarm occurs, the relay will turn on again. The purpose of
the Alarm Acknowledge button is to turn off any device connected to the relay such as a horn
