• 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 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 connector interface panel (TXP-CIP).

Table 1 describes the alarm LEDs.
