If any of these steps fail, or the ACU reports model "

xx

97", re-configure the PCU as described in the this

chapter. If initialization still fails, this indicates a drive or sensor problem, refer to the Troubleshooting
section.

7.3.3.

Troubleshooting using DacRemP

While troubleshooting a Sea Tel 3-Axis Antenna System, you must classify the fault you are dealing with as a
failure within one of 3 major system functions, Targeting, Stabilization, and Tracking.  Should there be a
failure with any one of these functions, your system will not operate properly.  A few simple checks may help
determine which fault (if any) that you are dealing with.  The matrix below lists some test(s) and which of the
DacRemP graph selection would be best to use to identify a fault.  The end of this chapter contains examples
on how to use DacRemP to diagnose a fault.

Targeting:

is the ability to accurately point the antenna to an angular position in free space and is

controlled by the ACU. (Does the system drive to the Azimuth, Elevation, and Polarity positions within 1
degree of the desired satellite?)

Stabilization:

is the process of de-coupling the ships motion from the antenna and is controlled by the

PCU. (Does the system maintain the satellite link after turning off TRACKING?)

Tracking:

is the process of issuing fine adjustments to the

pointing

angle of the antenna to optimize the

received signal level and is controlled by the ACU. (Does the system pass a four quadrant-tracking test?)
