Craft Interface Alarm LEDs
Two large alarm LEDs are located on the craft interface. Both LEDs can be lit
simultaneously.
•
The circular red LED lights to indicate a critical condition that can result in a system
shutdown.
•
The triangular yellow LED lights to indicate a less severe condition that requires
monitoring or maintenance.
The LCD display on the craft interface reports the cause of the alarm. A condition that
causes an alarm LED to light also activates the corresponding alarm relay contact on
the craft interface.
Table 8 on page 29 describes the alarm LEDs.
