Each Axis of the
RC2800PRKX2SU
needs to be configured for a spectrum of use and position of limits. The
programmable limits in the
RC2800PRKX2SU
control, give the ability to specify the amount of travel around a
spectrum of use. The AZ and EL 2 axis positioner has physical limits CCW / DWN and CW / UP. The limits
provide physical stops for safety due to control box failure. The CCW / DWN or CW / UP limits also create a
reference return for each axis when using the
“
Auto cal
”
feature during Remote/computer or manual control.
Below we have provided a visual explanation of some common axis configurations complete with suggested
electrical and physical limits and spectrum of use.
AZIMUTH AXIS OPTION #2
Characteristics
Spectrum of use: 240°
Over travel amount: 20°
SU Designation: Azimuth (S
-
center)
OVERVIEW:
This azimuth configuration may be used when
less than 360° of travel is necessary with a
southern exposure and avoids limits where most
of the operations are being preformed. Note the
position of the Physical limit switches, they are
on the outside of the electrical limits.
Again, this
provides safety when and if a control box fails.
AZIMUTH AXIS OPTION #1
Characteristics: Azimuth (S
-
Center)
Spectrum of use: + 360°
Over travel amount: 12°
SU Designation: Azimuth (S
-
center)
OVERVIEW:
This azimuth configuration may be used when
360° of travel is necessary with primarily a
southern exposer and avoids limits where most
of the operations are being preformed. Note the
position of the Physical limit switches, they are
on the outside of the electrical limits.
Ultimately,
this provides safety when and if a control box
fails.
