Camera Balancing Guide AXB-PT10/15 PosiTrack Camera Controllers IMPORTANT! READ THIS DOCUMENT BEFORE MOUNTING CAMERA Proper balance of the camera mount (with camera/lens/cradle) will result in optimal performance. Follow these balancing instructions prior to operation. Failure to balance the camera mount can result in poor performance. PT10/15 Camera/Lens Balancing The camera/lens assembly should be mounted so the tilt axis is capable of going through the optical axis of the camera, assuming the optical centerline is between 1/2" (12.70 mm) and 5" (127.00 mm) above the mounting plane of the camera lens. The mounting platform (camera cradle) allows the camera/lens to be mounted with its center of gravity on the tilt axis. The maximum weight of the camera/lens assemblies on the PT10 is 10 lbs. (4.54 kg) and on the PT15 is 15 lbs. (6.80 kg). The camera cradle is mounted to the Tilt Hub (FIG. 1). To find the center of gravity of the camera/lens/cradle assembly use a pipe or dowel-rod to balance the assembly, as shown in FIG. 3. 0.750" 19.05 mm 0.750" 19.05 mm 0.00" Position markers 0.750" 19.05 mm 0.250" 6.35 mm 0.00" 0.250" 6.35 mm 0.750" 19.05 mm cradle (bottom view) balancing beam FIG. 3 Balancing the camera/lens cradle assembly 5. Mount the camera as close to the Tilt Hub as possible to obtain a true center of gravity. 6. 7. Re-attach the camera mount (with camera/lens) to the cradle support bracket using the two 1/2" screws. Take the entire camera/mount and cradle assembly and align the lens with the Tilt Hub so that the vertical-axis intersects the center of the camera's iris, as shown in FIG. 4.

To mount and balance the camera/lens: 1. Separate the camera mount and the cradle support bracket by removing the two 1/2" screws on the underside of the assembly (see FIG. 2) using a 3/32" Allen wrench. Install the camera alignment peg to the mount at the position that best fits the camera/lens. Secure the camera/lens to the mount (at the camera alignment peg) with the 1/2" screw and 1/10" thick washer supplied (see FIG. 2).

Mark the position of the cradle support bracket on the Tilt Hub (for later attachment). Remove the camera/lens and mount piece from the support bracket by unscrewing the two 1/2" screws on the underside of the camera mount. 2. 3. 10. Secure the support bracket to the Tilt Hub (at the same position marked for the iris alignment) on the PT10/15 with some or all of the four 1/2" screws and washers. 11. Secure the camera/mount to the support bracket by using the two 1/2" screws. 12. Support the weight of the camera cables with a wire tie attached to the wire tie mount on the lower corner of the face of the PT10/15 (FIG. 5).

Place the assembly on a balancing beam and while maintaining the cradle centered on the pipe, slide the camera along the cradle's grooves until the camera and cradle remain balanced on the beam (FIG. 3).
