while the '*' character is displayed, the alpha-numeric data entry session is terminated. If the ENTER key
is depressed when the '*' character is not displayed, the cursor will advance to the right one space and
the user will be prompted again with the '*' character. If the ENTER key is depressed when the cursor is
in the tenth character position of the satellite name data field the entry is terminated.
5.6 RESET Mode
The RESET mode is used to display azimuth, elevation, and polarization drive fault conditions, and to re-
enable the drive outputs in the event the microcontroller has disabled an axis. When RESET mode is
activated, one of the following screens will be displayed.
AZ: OK EL: OK RESET
RESET AXIS: 1-AZ/EL
AZ: OK EL: OK PL: OK RESET
RESET AXIS: 1-AZ/EL, 2-POL
The first screen will be displayed if POL EQUIPMENT CODE CONFIG mode item is set to 0, the second
screen will be displayed if the POL EQUIPMENT CODE CONFIG mode item is set to 1 or 2.
The status of each axis is displayed after the appropriate banner (AZ:, EL:, or PL:) on the top line of the
LCD. If a fault exists for an axis, no movement may occur about that axis until the fault condition for that
axis is reset. Use the 1 key to reset the azimuth and elevation axes or the 2 key to reset polarization
axis.
Here are the status messages which may be displayed:
OK
Indicates that no fault conditions are active for the axis (azimuth, elevation, or polarization).
JAMMED
Indicates that the antenna was commanded to move about the axis and no movement was
detected by the controller. This indicates either that the antenna did not move when commanded
to do so, or the sensor failed and the controller was not able to detect any movement (azimuth,
elevation, or polarization).
RUNAWAY
The drive was deactivated because the processor sensed movement for a drive which was not
commanded to move. This error is rarely caused by an actual runaway condition (the antenna
moving on its own). This error is usually due to a faulty sensor or noise pickup due to the sensor
shield not being connected properly. See Chapter 3 for proper shield connection instructions
(azimuth and elevation).
DRIVE
The axis was deactivated due to a drive fault condition (azimuth or elevation axis).
SENSOR
This error will occur if the antenna commands a polarization movement, and movement is
detected in the wrong direction. Note that a polarization jammed condition will occasionally
register as a sensor error. Polarization movement in the wrong direction should only occur during
setup (polarization axis only).
