conditions for a Polarotor. The Polarotor is controlled in an open loop fashion (i.e. the controller cannot
tell if it is connected to a Polarotor or not - there is no position or status feedback from the polarotor).
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 axis, the 2 key to reset the elevation axis, and the 3
key to reset the polarization axis.
Here are the status messages that 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 that 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 an overcurrent condition (azimuth, elevation, and high current
polarization axis - RC2KHPP option).
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).
Note that the azimuth, elevation, and high power polarization (RC2KHPP only - not the RC2KPOL
option) axis are also protected from over-currents by a circuit breaker located on the back of the
controller. If the circuit breaker opens, the controller will report a JAMMED condition. Note that if
simultaneous azimuth and elevation movement is enabled, the total current draw for both axes cannot
exceed 8 amps. If the total current draw for both axes exceeds 8 amps, disable simultaneous azimuth
and elevation movement via CONFIG mode.
5.8 DELETE Mode
SELECT A SATELLITE: PANAMSAT-1 DELETE
USE SCROLL UP/DOWN, ENTER TO SELECT
This mode is used to delete a satellite entry. This mode can only be activated if the Expert Access flag
is set. Refer to section 2.5 for more information on the expert access system.
To delete a satellite from the controller’s non-volatile memory:
1. Use the MODE key to activate DELETE mode.
2. Scroll through the ASSIGNED satellite names.
3. When the desired satellite name is shown, press ENTER. The system will display the message:
DATA DELETED
