4.8.

F7: FREEWHEEL DETECTED

A drive axis freewheel has been detected. It is possible that a freewheel on a drive
display can clear itself and this alarm shows the cause of the axis becoming
uncalibrated.

Possible causes:

Axis hitting physical end stop.

Moving antenna under high wind or snow loading.

This alarm is latched, and has to be cleared through the alarm clear menu option.

4.9.

F8: 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 causing the calculated angle which the soft stop
uses to be seriously in error.

4.10. F9: TX POL SWITCH FAILED

The TX polarisation switch, if fitted, 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.

4.11. F10: AZIMUTH STOW SENSOR FAILED

The sensor used to detect the azimuth tab markers has failed. Possible causes:

Sensor disconnected.

Sensor failure.

Metal stuck in sensor.

4.12. F11: ELEVATION STOW SENSOR FAILED

The sensor used to detect the elevation tab markers has failed. Possible causes:

Sensor disconnected.

Sensor failure.

Metal stuck in sensor.

4.13. F12: POL STOW SENSOR FAILED

The sensor used to detect the polarisation markers has failed. Possible causes:

Sensor disconnected.

Sensor failure.

Metal stuck in sensor.

4.14. F13: EL DP SENSOR FAILED

Currently not used in the DCU5000 system. If seen please report the occurrence to
Advent Communications customer support.

4.15. F14: FA DP SENSOR FAILED

Currently not used in the DCU5000 system. If seen please report the occurrence to
Advent Communications customer support.

4.16. F15: EL STOWED SENSOR FAILED

Currently not used in the DCU5000 system. If seen please report the occurrence to
Advent Communications customer support.
