TX Matrix Alarm LEDs on the Craft Interface

 

Two large alarm LEDs are located at the left of the craft interface (see Figure 1). 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.

A condition that causes an LED to light also activates the corresponding alarm relay contact on the connector interface panel (TX-CIP). The LCD display on the craft interface reports the cause of the alarm.

Table 1 describes the alarm LEDs in more detail.
