4.17. F16: FPGA PROGRAMMING FAILED
The field programmable gate array IC has failed to be programmed. Possible causes:
FPGA IC failure.
FPGA IC connection failure.
4.18. F17: MANUAL BRAKE OVERRIDE ON
The manual brake override is in use.
Possible causes:
The manual brake override switch has not been put back into the automatic
position.
4.19. F18: AZIMUTH STOWING FAILED
The system failed to detect the correct azimuth stow sensor. The system will search
±10° from its expected stow position for the tab marker. Possible causes:
Excessive stall or freewheel has uncalibrated the axis so much the systems azimuth
angle is in error by more than 10°. Action: re-calibrate axis.
The stow marker is not present.
The stow sensor or drive circuit has failed.
4.20. F19: ELEVATION STOWING FAILED
The system failed to detect the elevation stow sensor in at its expected position.
Possible causes:
Excessive stall or freewheel has uncalibrated the axis so much the systems internal
elevation angle is in error by more than 2°. Action: re-calibrate axis.
The stow marker is not present.
The stow sensor or drive circuit has failed.
4.21. F20: POL STOWING FAILED
The system failed to detect the polarisation stow sensor in at its expected position.
Possible causes:
Excessive stall or freewheel has uncalibrated the axis so much the systems
polarisation angle is in error by more than 2°. Action: re-calibrate axis.
The stow actuator is not present.
The stow sensor or drive circuit has failed.
The polarisation calibration data has been corrupted.
4.22. F21: EL DP STOWING FAILED
Currently not used in the DCU5000 system. If seen please report the occurrence to
Advent Communications customer support.
4.23. F22: FA DP STOWING FAILED
Currently not used in the DCU5000 system. If seen please report the occurrence to
Advent Communications customer support.
4.24. F23: POWER UP STATE SUSPECT
The system has been powered down when not physically stowed. The alarm warns the
user that the system is not physically stowed.
This alarm is latched, and has to be cleared through the alarm clear menu option.
4.25. F24: STOW SENSOR POWER FAILED
The stow sensor power supply is out of specification. Either the supply has been
shorted on the antenna, or an internal DCU5000 supply rail has failed.
