D. LED Indicators
WRU Undeployed
After removing both batteries from an undeployed WRU, and then replacing BAT A, BAT B, or
both, when the first battery is connected, the WRU goes through the power on LED sequence
and then remains in the undeployed state.
The following table shows the LED power-on sequence for an undeployed WRU:

Summary
Description
Undeployed
Dead batteries
If no LEDs are on (lit up) on an undeployed
WRU, it can be one of the following scenarios:
•
Unit undeployed
•
Batteries dead
When you do a tilt test (geophone down) on
an undeployed 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 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.
Geo down tilt
detected
Deploy
Tilt the WRU with the geophone pointing
down.
After a few seconds, all of the LEDs light up
solid.
Place the WRU flat on the ground to within
five seconds to begin the deployment
process:
•
Battery fuse self-test
•
Battery test
•
THD test
•
Geophone test
•
GPS fix
•
Radio test
