3.2.3. Polarization Related
3.2.3.1. Polarization Current Limit Error
Cause 1:
Current used to move the Polarization exceeds the fixed limit, which
resulted in a current spike. The Mobile Platform may have been
obstructed by a foreign object and does not have enough clearance to
rotate left or right.
Solution 1:
Ensure that the Polarization path has enough clearance for free
movement.
Cause 2:
Polarization Current limit is set too low.
Solution 2:
Verify the default slow speed on the Polarization, and Default Current
Limits depending on the controller and platform type. Modify if Required.
5000 / 9000 – Go to Advanced in the Maintenance Menu (ensure your in
configuration mode)
7000 Controller – Go to the Maintenance Menu, and check in the
Polarization section.
See Appendix A for 5000/9000 Controller default speeds and limits.
See Appendix B for 7000 Controller default speeds and limits
Cause 3:
If the Mobile Platform physically moves, and the Stow ST Limit is off, but
the Polarization angle doesn’t change, then it may be a problem related to
the potentiometer.
Solution 3:
Ensure the potentiometer is properly calibrated. (i.e. 2.5 turns when
polarization is in center position), If so, then the potentiometer might need
replacement – contact support.
