4.25 F8: DRIVE END OF TRAVEL DETECTED
A drive axis travel limit has been detected. The axis causing this will become uncalibrated.
Possible causes:
Severe axis stall or freewheel has caused the calculated angle which the soft stop uses to be
seriously in error.
4.26 F9: TX POLARISATION SWITCH FAILURE (OPTIONAL)
The TX polarisation switch has been detected in an illegal state, or will not respond to switch
commands. Possible causes:
Manual operation of the switch with the DCU on will trigger this alarm.
Switch is disconnected.
Switch is stuck or jammed.
4.27 F10: AZIMUTH STOW SENSOR FAILURE
The sensor used to detect the azimuth tab markers has failed. Possible causes:
Sensor disconnected.
Sensor failure.
Metal stuck in sensor.
4.28 F11: ELEVATION STOW SENSOR FAILURE
The sensor used to detect the elevation tab markers has failed. Possible causes:
Sensor disconnected.
Sensor failure.
Metal stuck in sensor.
4.29 F12: POLARISATION SENSOR FAILURE
The sensor used to detect the polarisation markers has failed. Possible causes:
Sensor disconnected.
Sensor failure.
Metal stuck in sensor.
4.30 F16: DCU FPGA PROGRAMMING FAILURE
The field programmable gate array IC in the antenna DCU has failed to be programmed.
Possible causes:
FPGA IC failure.
FPGA IC connection failure.
4.31 F17: MANUAL BRAKE OVERRIDE ON
The manual brake override in the antenna DCU is in use. Possible causes:
The manual brake override switch has not been put back into the off position.
