CLEAR TRACKING MEMORY
Clicking to this mark clears the tracking memory. You should do this when you start to track a new
satellite. Clearing the tracking memory about half an hour after tracking started significantly
improves the quality of the first adaptive tracking model which will be evaluated after 6 hours of
tracking. This is because the model does not get disturbed by the first search steps the antenna
does until the optimal pointing to the satellite is found.
Please refer to chapter
8.3 Steptrack
,
8.4 Adaptive Tracking
and
8.5 Program Tracking
for more
detailed informations about the tracking algorithms.
The page 'Test' displays the electrical / logical level of all inputs and outputs of the ACU. This
helps you to install the ACU or to identify a malfunction of peripheral components. The layout of
this page differs slighty for ACUs equipped with a fourth axis. The POL2 raw angle encoder
reading and the state of the extended inputs / outputs are displayed additionally for the 4 axis
ACU.
Below some information how to interpret the values in this page are given.
Electrical I/O Levels
The electrical state of an input or output is indicated by the HI / LO label displayed with the signal.
HI means that current is flowing through the optocoupler for this input or output. LO means that
no current flows. As some signals are defined to be 'true' when a switch is opened, the electrical
level of the signal not necessarily describes the logical level of this signal, too.
