3.2.3.2. Polarization Jam Error

Cause:
Indicates that current is being sent to the Mobile Platform to deploy the
Polarization, but the Polarization angle does not change.
Solution 1:
1. Ensure that the Motor Control Cable is securely connected at the
iNetVu™ controller and Mobile Platform.
Solution 2:
1. Go to Advanced Controls
2. Set Duration to 100
3. Set Speed to H or 9 (Dependant on mode of operation)
4. Click Polarization CW in Manual Controls. Monitor the PL Motor
Current and record the highest value.
Result:
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.
If the Mobile Platform doesn't physically move and there is no Polarization
current reading, then it may be a problem related with the iNetVu™ Controller.
Cause 3: Burned Fuse.
Solution 3: Replace the 5/10 AMP Polarization Motor Fuse on the
controller board.
