4.1.1 Node Indicator LEDs


Power: On start-up, this indicator will be RED while the start-up sequence checks that all of
the internal power rails are the correct voltage. On satisfactory completion of these checks
(between 5 and 10 seconds) the indicator will change to GREEN. If any voltage rail moves
out of specification during operation, the LED will change to RED and an alarm will be
raised by the Hub Unit.
 Status: On power up, the Status indicator will be RED while the Node communication
circuits are checked and time bases are synchronised. This will take about 10 seconds.
The indicator light will change to GREEN on successful completion. If any of these
parameters moves out of specification during operation, the LED will change to RED and an
alarm will be raised by the Hub Unit.
 TEV: The TEV LED shows the status of the TEV input based on alarm criteria defined at the
Hub Unit. If an alarm is active the LED will be RED, otherwise, the LED will be GREEN.
 Ultrasonic: The Ultrasonic LED shows the status of the Ultrasonic inputs based on alarm
criteria defined at the Hub Unit. If an alarm is active the LED will be RED, otherwise, the
LED will be GREEN. If no ultrasonic sensors are connected, the LED will be turned OFF.

Cable PD: The Cable PD LED shows the status of the Cable PD inputs based on alarm
criteria defined at the Hub Unit. If an alarm is active the LED will be RED, otherwise, the
LED will be GREEN. If no Cable PD sensor is connected then the LED will be turned OFF.

4.1.2 Node Connections

The UltraTEV Monitor has a number of connections (see Figure 12 for connector positions).
 TEV Sensor: This input is for the connection of an external TEV probe or antenna.
