Switching sensor from rotator's primary sensor to ARXC.MAG
Choice when ARCO was calibrated with original rotator's sensor but sensor suddenly failed.
Prerequisite:
ARXC.MAG is in ACTIVE state.
•
In Menu->Rotator->Settings change Sensor from the primary to ARXC.MAG.
ARXC.MAG calibration is automatically used and ARXC.MAG becomes the primary
sensor for all rotator operation.
Note, that at this point, the original primary sensor's calibration is lost, and after restoring the
original sensor as primary sensor in Menu->Rotator->Settings->Sensor, new calibration of this
sensor is required. If there is a stored configuration from previous steps, loading it through
Menu->System->System->Config LOAD restores the setup from that point, including original
sensor's calibration, as expected.
ARXC.MAG as the sole azimuth sensor
Choice for rotators without azimuth sensor.
Prerequisite:
ARXC.MAG is selected as primary sensor in Menu->Rotator->Settings.
•
In Menu->System->ARXC.MAG set ENABLE box. Status changes from DISABLED to
SENSOR POINTS. It is possible that an interim INIT state is displayed for a few seconds,
it is normal. If Status did not change to SENSOR POINTS, check prerequisite.
•
Now in Menu->Heading->Calibration, turn the rotator to at least 4 evenly spaced points
by 90˚ (i.e. North, South, East, West), and enter azimuth for these calibration points using
CUSTOM button. You can add calibration points more densely than that.
•
After all Calibration Points have been entered press the FINISH button. Move to the
center of rotator rotation and enter its azimuth, to finalize the calibration.
If the rotator has limit switches and they are enabled in Menu->Rotator->Settings, in
Menu->Heading->Calibration an AUTO button is displayed. By pressing AUTO button, the motor
will automatically move first to the CCW limit switch, and then while moving to the CW limit
switch it will gather calibration points, assuming that the rotator moves with a constant angular
speed during the whole path between the limit switches. Finally, the rotator moves into the
estimated mid-position. Here, adjust the position of rotator to precise center of rotator rotation
and enter its azimuth. This finalizes the calibration assuming that angular distance between limit
switches is exactly TOTAL ROTATION parameter.
As usually, after calibration it is recommended to store the current ARCO state into one of the
Menu->System->System->Config SAVE slots.
Please note, once ARXC.MAG becomes the primary sensor, ARXC.MAG cannot be disabled
and slip is checked on power up and wake up from sleep.
