height of the centre of gravity of the system, including pan bar and lens controls if
these are to be fitted.
Loosen the three hex-socket screws securing the tilt platform to tilt flange and raise it
to bring the estimated vertical position of the camera/lens centre of gravity in line
with tilt axis and tighten the three socket screws.
For efficient control, it is essential that the whole load, including the cables, be
properly balanced about the tilt axis.
Connect the cables at the Head only and dress them to impose minimum drag while
allowing full pan and tilt movement.
3.2.3. Switching On
With power off, remove the tilt-locking pin and transfer it to its storage position on the
side of the head.
Release the pan and tilt brakes and set the pan and tilt dampers to minimum. Plug in
the head cable and switch on the power.
Switch the head to Remote mode using the Local/Remote switch on the front panel
of the Lens I/F Unit, which is mounted on the side of the head. Ensure that the
indicator on the side of the head is illuminated confirming that the head is indeed
under remote control.
A small movement may be observed in the pan and tilt head axes. If this is greater
than 5 degrees in either pan or tilt, then there is a fault in the system.
Run tilt slowly from end to end and check that it does not hit its mechanical end
stops. It should be noted that pan does not have a mechanical end-stop, the travel
being limited electrically.
N.B. Some heads may have mechanical end-stops fitted for the pan axis.
