The following table shows the possible LED indicators for a WRU that is deploying:
Table D–3 WRU LED Indications, Deploying Sequence
LED Indicators Summary Description
Dead batteries
Defective Unit
If no LEDs are on (lit up) during the deploying
state, it can be one of the following scenarios:
• Batteries dead
•Defective Unit
When you do a tilt test (geophone down) on a
WRU with no LEDs on, the following may
occur:
• A WRU with dead batteries will continue
to display no lit LEDs
• A WRU is defective if no LEDs turn on
after battery replacement.
NOTE: Battery state is shown in the RT
System 2 user interface tables. For
example, the Ground Equipment
Table.
A is solid for 5 seconds
BAT remains solid
Battery fuse test
failure (A)
When both batteries are installed, the battery
fuse test is performed.
A Solid for 5 seconds
BAT Solid
A solid BAT LED indicates that the WRU
detected a bad fuse during deployment and
returned to the undeployed state. When a
battery fuse test fails, the WRU will not
deploy.
Both batteries must be present for the battery
fuse test to execute. This allows you to deploy
a WRU by removing the battery connected to
the bad fuse prior to the deployment tilt
action.
