3.3.6 Circle mode

The feature EXTRA - CIRCLE offers direct control of circle movements. The
actual Pan/Tilt position will be the centre point of the circle movement, radius
and speed can be controlled by encoder. By moving the Pan/Tilt position, the
circle will move simultaneously.
Circle parameters can be stored as presets like any other feature and can also
be stored within memories, chasers or sequence steps.

Any circle movement can only be terminated by turning the radius to zero or
by recalling a preset, which sets the radius to zero.
For keeping control of circle movements and to have the chance to terminate
circles as quick as possible, it is recommended to program a preset for circle
"OFF".
Using the selective way of programming memories and sequence steps, it is
important to have one of the memories S1 to S10 stored as "CIRCLE OFF"
memory. (>> 4.3 Selective memories)
When a circle movement is terminated by setting the radius to zero, the beam
returns to the centre of the circle.
During any programming of positions make sure, that the circle radius is set to
zero. If only the circle speed is zero, but the radius is greater zero, there is no
circle movement visible, but the radius is still valid and will cause an offset on
the programmed positions.
Direct access to the CIRCLE feature can be done
with encoder or presets like on any other feature. At
least one preset should be prepared with speed and
radius set to zero for all scans.
SCAN Selection
Controls the speed. Crossing zero will change the
direction.
As long as the radius is zero, a starting angle can be
set between 0 to 15 (=F). This helps to start the
different scans at different positions of the same
circle.
