J14 provides a double row of pins. The bottom 16 pins are designated "J14B" and is typically allocated to
supporting an inclinometer, pulse and limit switch feedback from the elevation axis.
If present, the elevation up switch must be open when the elevation axis has reached the up limit. If the
elevation up limit switch cable is severed, the RC4000 will think that the elevation axis is at the up limit.
Logic within the RC4000 will not allow the elevation axis to move up if an up limit condition is recognized.
If present, the elevation down switch must open when the elevation axis has reached the down limit. If
the elevation down limit switch cable is severed, the RC4000 will think that the elevation axis is below the
down limit. Logic within the RC4000 will not allow the azimuth axis to move when the elevation down
condition is recognized.
If present, the elevation stow switch must open when the elevation axis has reached the stow position. If
the elevation stow limit switch cable is severed, the RC4000 will think that the elevation axis is at the stow
position. Logic within the RC4000 will not allow the elevation axis to move down when the elevation stow
condition is recognized.
