Beacon level --- This field shows the beacon level as read from the beacon receiver.
Depending on the source defined at the
Setup
page, this either is the beacon level reported
by a sat-nms LBRX beacon receiver via TCP/IP of the level derived from the ACU's analog
input.
Temperature --- The actual temperature inside the ACU enclosure. This value is for
information only.
ACU Faults --- If there are any faults with the ACU, they are displayed in this field. If there is
more than one fault at a time, the ACU concatenated the fault descriptions. More detailed
information about faults are available in chapter
Faults and Tracking
. If one axis stops
operation due to a fault, the step tracking also stopps operation. Possible faults are:
EMERGENCY-STOP --- Someone opened the emergency stop circuit. The ACU
stopped all motors and stays in this state until the 'RESET' button at the navigation bar
is clicked.
HUB-FAULT --- The ACU detected a 'hub fault' condition.
CABINET-OPEN --- The ACU detected a 'cabinet open' condition.
BCRX-TIMEOUT --- If the ACU reads the beacon level via TCP/IP from a sat-nms LBRX
and the latter does not respond, a BCRX-TIMEOUT fault is reported
Tracking Faults --- If the ACU has the tracking option installed, any faults of the tracking
module are shown in this field. With tracking option, this field is always empty.
AZ/EL Tracking State --- If the ACU has the tracking option installed and ADAPTIVE tracking
is selected, these give some information about the model of antenna/satellite movement the
ACU has calculated from the step track data:
M(model) --- The complexity of the model the ACU uses (small/medium/large). With a
small amount of tracking data available, the ACU uses a smaller, less complex model
than with a completely filled tracking memory.
A(amplitude) --- The amplitude of the antenna movement in this axis, expressed as a
percentage of the full 3dB beamwidth.
J(jitter) --- The jitter of the antenna movement in this axis, expressed as a percentage
of the full 3dB beamwidth.
B(beamwidth) --- The 3dB beamwidth as calculated by the ACU from the antenna
diameter in this axis and the beacon receive frequency. This is the full beamwidth, the
angle between both 3dB points in the antenna pattern.
S(step size) --- The absolute step size used by the step track in this axis.
Time --- The actual time of the ACU's internal clock.
GPS State --- The actual state of an external GPS receiver connected to the ACU (if
applicable).
The page 'Targets' gives access to the ACU's target memory. The ACU is capable to remember
the pointing (and tracking parameters, if the ACU has the tracking module installed) of up to 199
satellites. Managing these memories is done with the 'Targets' page. Target memories are
organized in 10 pages with 20 memory places each, you may click to the numbers shown above
the table to select a certain page. Addidtionally, the target memories may be sorted either by
target number, by azimuth angle or by name. Click to the sort modes above the table to select
the appropriate sort mode.
