Alarm LEDs and Alarm Cutoff Button
Two large alarm LEDs are located at the upper right of the craft interface. The circular
LED called major alarm LED glows to indicate a critical condition that can result in a
system shutdown. The triangular LED called minor alarm LED glows to indicate a less
severe condition (warning) that requires monitoring or maintenance. Both LEDs can be
lit simultaneously.
A condition that causes an LED to be lit also activates the corresponding alarm relay
contact on the craft interface.
The alarm cutoff/lamp test (ACO/LT) button, located next to the alarm LEDs, is a control
button for alarms. You can press the ACO/LT button to deactivate major and minor
alarms. Deactivating an alarm turns off both LEDs and deactivates the device attached
to the corresponding alarm relay contact on the craft interface.
Table 12 on page 24 describes the alarm LEDs and the alarm cutoff/lamp test button.
