Balancing the Camera
The Protean XMi can cope with slightly out of balance
loads, but when power is removed the camera will tend to
rotate about the TILT axis to settle at the balance position.
With power removed adjust the balance of the camera so
that it doesn't move or just moves to a settling position
that you have set by balancing.
One suggestion is to balance the camera Fore and Aft
perfectly but allow it to be slightly lower than neutral so
that it tends to settle horizontally when the power is
removed.
There are 3 bolts securing the camera plate to the drop
arm. These are used to adjust the camera plate up and
down for perfect balance.

PID Adjustment
For certain camera loads with a higher moment of inertia it may be necessary to adjust the
PID (Proportional, Integral, Differential) values of the motors.
These will need adjusting if the camera oscillates, overshoots a position or under shoots a
position.
For details of how to adjust the PID values contact BR Remote for advice and guidance.
Pan & Tilt Home Position
When the unit powers up it needs to find its absolute
HOME position. Both the Pan and Tilt HOME positions
are indicated with arrows on the pan and tilt axes.
It is
very important
camera that these positions are
arcs
of pan and tilt. Make sure that when the camera
pans and tilts it can pass both these positions.
Failure to ensure this will render the pre-set positions and
profile moves unusable.
A 'User Home' position can be set if required.
absolute HOME position cannot be changed.
If the unit fails to HOME correctly it can be driven to a
position close to HOME and use the 'Re-Home'
command.
