LED Indicators Summary Description
Undeployed
Dead Batteries
Sleeping
If no LEDs are on (lit up) before tilting the
WRU, it can be one of the following scenarios:
• WRU undeployed
• Batteries dead
•WRU Sleeping
• WRU Awake, but unformed
When you do a tilt test (geophone down) on a
WRU with no LEDs on, the following may
occur:
• An Undeployed WRU deploys and begins
the self tests
• A WRU with dead batteries will continue
to display no lit LEDs
• A Sleeping WRU goes back to the
deployed, unformed state and displays
the battery status and any self-tests that
failed during deployment (BAT, THD, GEO,
GPS, or RAD).
• A WRU in the Awake unformed state
displays the battery status and any self-
tests that failed during deployment (BAT,
THD, GEO,GPS, or RAD).
NOTE: Battery state is shown in the
RT System 2 user interface tables.
For example, the Ground Equipment
Table.
Battery A in use A Flashing:
• Battery A in use
• WRU formed or Armed
NOTE: Only when GPS position occurs at the
same time the battery status is
displayed.
Battery B in use B Flashing:
• Battery B in use
• WRU formed or Armed
NOTE: Only when no self-test failures. Re-
acquire GPS position occurs at the
same time the battery status is
displayed.
