4 – Limit Switches (L: EEE)
Allows the enabling and disabling of the UP, DOWN, and STOW limits
respectively.
The first character (
E
EE) represents the UP limit. The second character (E
E
E)
represents the DOWN limit and the third character (EE
E
) represents the STOW
limit. The user my change the limit configuration between:
D - Disable Limit
This option disables UP, DN, and ST limits for testing and troubleshooting (i.e. DEE – represents
disabled up limit, and enabled down and stow limit).
E – Enable Limit
Once enabled, the up, down and stow limits will be activated whenever the up, down, and stow
sensors have been triggered on the iNetVu
®
Mobile platform.
5 – Elevation Search Window
The Search Window is the area of the sky which the iNetVu
®
Mobile System will
search for the desired Satellite. It uses a rectangular window and searches for
the Satellite using smaller concentric windows until the desired Satellite is found.
The Search Window range is pre-set by default for optimum performance;
however this offset may be manually changed in the range of 2º-20º.
Fig. 42:
Elevation Coverage of search window
The default Elevation (Vertical) range is 3° on each side of the Target Point.
Increasing the size of the Search Window will increase the ability to find the
desired Satellite, although increasing the Search Window will lengthen the
search time. The search window will expand from 3 to 5 if first search run fails to
lock on satellite.
6 – Current Settings
A software controlled current protection for the Mobile Platform’s elevation
motors. When any of the Mobile Platform’s motors are moving at the associated
speed, the current drawn to move the motor is monitored and should it exceed
the Current Limit, an error message will appear. For Motor Speeds that are not
listed (Speed 1, 2, 4, 5, 7, 8), the Current Limit for those speeds is calculated
using a percentage of the Current Limit above it. See Appendix 1 for the default
current limits for all iNetVu
®
Mobile Platforms.
