<strong>Fusion</strong> <strong>FH</strong>-<strong>100</strong> <strong>and</strong> <strong>FH</strong>R-<strong>100</strong> pan <strong>and</strong> tilt heads<br />
Centre of Gravity (C of G) height adjustment<br />
Fore <strong>and</strong> aft balance must be set before adjusting the payload C of G vertically to the tilt axis.<br />
To adjust the C of G height, proceed as follows:<br />
26<br />
1. Switch OFF power to the head [18] <strong>and</strong> engage the tilt lock [7].<br />
2. Loosen the three screws [3] securing the camera cradle to the tilt drive, <strong>and</strong> raise the<br />
camera cradle [1] to vertically align the camera assembly C of G with the tilt axis.<br />
NOTE: Depending on the camera configuration, it may be necessary to use an intermediate<br />
plate (part no. 3384-11) to raise the C of G height sufficiently to align with the tilt axis<br />
(see Balancing the head <strong>and</strong> payload on page 25).<br />
3. Tighten the three screws to secure the camera cradle into position.<br />
4. <strong>FH</strong>-<strong>100</strong> only: Check that the head is set to robotic mode (AUTO). Note that the mode<br />
can only be switched from the control panel.<br />
5. Disengage the tilt lock.<br />
6. Tilt the camera approximately 30° upward <strong>and</strong> release it.<br />
• If the camera stays in the same position when released, the payload is properly<br />
balanced with the C of G on the tilt axis. Continue with step 7 of this procedure.<br />
• If the camera continues to move upwards after releasing the camera cradle, the<br />
payload is mounted too high—lower the camera cradle.<br />
• If the camera moves back towards the horizontal position when released, the<br />
payload is mounted too low—raise the camera cradle.<br />
7. Reposition the camera cradle vertically as required (repeat steps 2–6), until balance<br />
is achieved.<br />
8. After the C of G height has been adjusted, it may be necessary to check that the fore<br />
<strong>and</strong> aft balance remains satisfactory. Readjust the position of the camera horizontally<br />
on the camera cradle as required.<br />
9. After balancing, exercise the head through both axes to confirm that it operates<br />
smoothly.<br />
NOTE: Care should be taken when removing or repositioning any accessory equipment<br />
mounted of the camera cradle to ensure that the head remains balanced—this<br />
includes repositioning the pan bar h<strong>and</strong>les.
