The following table shows the possible LED indicators for a WRU that is deploying:

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.
