Automated Set Software Limits
This step in the Initialization Wizard is an automated step that gets activated as soon as the obser ver box is
checked. The antenna controller operator is not required to enter anything for this step but ma y interrupt the
process with an emergency stop. (See Figure 20 .)
Figure 20: Automated Set Software Limits Screen
The antenna controller operator must wait for each of the software limits check boxes to appear. T he
process slews the antenna to the hardware limits and then sets the software limits 1 degree in f rom the
hardware limit. Since the antenna must be physically slewed to each of the limits, this process can take
considerable time. After the initialization is complete the software limits may be adjusted by m odifying the
values in the Review Parameters Screen. The valid ranges for Software Limits are displa yed in Table 2.
NOTE: East and West limits may NOT be set in the same quadrant or the tracking process es will not
work.
WARNING
An observer must be at the antenna to request an
emergency stop if the hardware limits fail.
