RC4000 ACU Boardset

3.2.2.2 Stow

The STOW mode automatically moves to the mount's predefined "stow" position. See Appendix B for the
list of stow positions for the various mounts supported.
Like the DEPLOY mode, STOW requires an explicit confirmation to initiate movement.

After initiation a sequence of movements will be performed to stow the antenna. The sequence of axis
movements will be mount dependent. As each axis moves, its label (AZIM/ELEV/POL) will flash and the
current position will update. The target stow positions will be displayed in parenthesis.

MOVING TO (STOW)
The following describes a typical sequence of movements:
- the azimuth axis is moved to its predefined stow position (typically AZIM:0.0). After moving to this
indicated position, the RC4000 will confirm the position by looking to see if the azimuth stow switch is
active. If the azimuth stow switch is not recognized, the mount will be moved a short distance to either
side of the current position trying to find the azimuth stow switch. If the controller fails to see the azimuth
stow switch the following message will be displayed: "*CANNOT FIND AZ STOW SWITCH*
<MODE>EXIT" and no further stow movements will be performed.
- if stowing of the polarization axis is enabled, the polarization axis will next move to its predefined stow
position. As with the azimuth axis, if a polarization stow switch (if the mount is so equipped) is not
confirmed then the message "*CANNOT FIND POL STOW SWITCH* <MODE>EXIT" will be displayed
and no further stow movements will be performed.
- if the azimuth and optional polarization movements complete successfully, then the elevation axis will
move to its stow position. Typically this movement ends when the elevation stow limit is encountered.
Following completion of movement to the stow position, the RC4000 will return to MANUAL mode. The
automatic movement may be terminated anytime by pressing the Stop key.
Many mounts have unique stow sequence requirements. Check Appendix B to see if your mount has any
unique stow situations. The azimuth, elevation and polarization deploy positions are defined in the
Stow/Deploy configuration screen (3.3.1.3.10). Typically the default parameters will be correct for a
particular mount.
