2. If the problem is not resolved, check the sensor board. Replace the
sensor board.
3. If the cable and sensor board do not have a problem, check the
sensor connector of the PCU.
Symptom #8
Operation of the sensor cage is OK, but the elevation or cross axis is not
working.
(In normal: Elevation and cross axis are moving to level off the sensor
cage after operation of the sensor cage.)
Check Point
1. Check the motor driver. Replace the motor driver.
2. If the antenna still has a problem, please replace the elevation motor
or cross motor.
3. If the problem is not resolved, you must check the cable between the
motor driver and the PCU.
4. Lastly, check the motor driver connector of the PCU.
Symptom #9
The azimuth axis does not move after the sensor cage stays parallel to
the ground.
(The azimuth axis normally moves once the cage is parallel and stable.)
Check Point
1. Check the motor driver. Change the motor driver.
2. If the problem is not resolved, change the azimuth motor.
3. If the problem is not resolved, you must check the cable between the
motor driver and the PCU.
4. Lastly, check the motor driver connector of the PCU.
Symptom #10
All axes of the antenna are not working after initializing. The antenna
has a ‘PCU error 0X 40 00 00 00’.
Check Point 1. Check the hall sensor. Replace the hall sensor.
