C of G height adjustment
When the fore and aft balance has been achieved, align the payload C of G vertically to the tilt
axis as follows:
Ensure that the power to the head is switched off.
Tilt the platform [6] forwards and backwards to test the C of G alignment. If the
alignment is correct the head will remain at any angle of tilt unassisted. If the platform
[6] angle tends to return towards horizontal when unsupported, you need to raise the
platform [6]. If the platform [6] angle tends fall forwards or backwards away from
horizontal you need to lower the platform [6].
Mark the position of the payload and the platform and remove the payload.
Loosen the 2 platform fixing screws [2] securing the platform [6] to the tilt drive and
raise the platform [6] to vertically align the camera assembly C of G with the tilt axis.
Tighten the 2 platform fixing screws [2] to re-secure the platform [6].
Install the payload in the position marked in step 3.
Recheck the C of G alignment (step 2) and repeat steps 3 through 6 if necessary.
After adjusting the C of G height, it may be necessary to re-check that the fore and aft
balance is still correct. Re-adjust the position of the camera horizontally on the platform
[6] as required.
After balancing, exercise the head through both tilt and pan axis to confirm that it
operates smoothly.
Warning!
1. Switch off the power to the head before making any adjustments to
the head.
2. Risk of finger trap in moving parts. The total camera payload can
reach 34 kg (75 lb). Take the necessary precautions to safely handle
this weight before loosening the platform fixing screws [2].
3. Do NOT remove the platform fixing screws [2] while the platform is
loaded.
NOTE: If required, use an intermediate plate to raise the C of G sufficiently to align
with the tilt axis.
NOTE: Ensure all cables are connected to the camera and lens, and dress them to
impose minimum drag and allow full movement about the tilt axis. The weight
of the cables should also be balanced about the tilt axis.
