Power Control - PROAIM Kite-22 Instruction Manual

PROAIM KITE-22 ULTIMATE PACKAGE

POWER CONTROL

To the right and above the joystick is a knob labeled "SPEED".
This is the power control knob. Turning to the right will be full power and back to the left will
decrease the available power to both pan and tilt operation. The advantage of power control is
to be able to limit power when only slow accurate movements are needed. With the power
control at half power (approx. 8 volts max. output) the full range of motion on the joystick will
be between 0 and 8 volts making finer adjustments possible. The power control will be usable
between a range of approximately 4 volts to 12 volts.
DEAD SPOT
The knob to the left is marked Dead Spot. Turned all the way to the left (counterclockwise) will
create the smallest dead spot. Meaning that the head will begin to move as soon as the
smallest deflection of the joystick is made. Moving to the right will increase the area where no
power is sent to the head motors. At half way, the dead spot will close again, this helps to avoid
crossing the tilt when only pan movement is desired.
The dead spot is so tight when the control knob is all the way to the left, it may be necessary to
back it off slightly until no movement is seen in either axis.
Note: With the dead spot all the way left the head may move in both axis on it's own. The dead
spot should be set at approx. the 9:00 position to insure that no unwanted
occurs.
Linear or Logarithmic taper joystick control
All joysticks are linear, meaning that each degree of movement of the stick correlates to the
output. On the 12 volt PROAIM PAN TILT HEAD half deflection of the joystick means
approximately 6 volts sent to the motors. But with the advent of Digital we can now control the
taper of the joystick, making in Logarithmic as well. Logarithmic taper being that the first of
joystick movement only sends a small amount of power to the motors and the last of the
deflection will send more power per degree of deflection. On Logarithmic taper 1/3 of joystick
deflection might yield 2 volts output the next 1/3 will yield 4 volts output and the last 1/3 of
yields 6 volts for a max. again of 12 volts. This mode gives the operator fine slow movements
yet retains the ability to go to max. speed if necessary.
PAN DIRECTION SWITCH
When the Pan-Tilt Head is used on a Tripod or on a Jib.
When the head is shifted from a Jib to a tripod, it needs reversal of direction as the location of
the head will be inverted. By switching "on" the pan direction switch, we can immediately
reverse the direction. When the joystick is moved to the right it gives right rotation as it gives
while mounted on the tripod directly.
