SECURING THE COUNTERWEIGHT SYSTEM
1.
This step must be done after attaching the scroller and DMX Iris to ensure proper balance.
2.
Facing the back of the lighting fixture, line up the holes on the bottom of the counterweight halo with
the matching holes on the rear of the connector box. Use two of the counterweight screws (1/4 -
20
x 3/4” socket head cap screws) to secure the counterweight halo into place.
3.
The 10 counterweight rings provided with the AutoYoke should be added one at a time until the lighting
fixture is in balance. Facing the back of the lighting fixture, position the
Lead
rings on the back of the
counterweight halo, lining up the holes. Add Lead weights until the AutoYoke is close to the point of
balance and then add a Steel ring last to sandwich the lead weights. Use the remaining two counter
weight screws (1/4-20 x 2” socket head screws) to secure the rings into place.
***Note: If you are operating the AutoYoke with a Chroma Q scroller you may not need to add the
lead counterweight rings.
TIGHTEN ALL HARDWARE.
4.
The lighting fixture will be in balance when it freely drifts to a horizontal position (perpendicular to the
AutoYoke).
Operating the AutoYoke with the lighting fixture out of balance will result in inaccuracy.
***Note: If you are operating the AutoYoke without a scroller or with the lens tube of the lighting
fixture run all the way in, you may not need to add the counterweight rings or the counterweight
halo. In addition, the counterweight quantity may have to be adjusted once the lens tube position is
established. Operating the AutoYoke without a scroller will create an out of balance condition that
will not effect the accuracy or repeatability of the AutoYoke. Though not critical, this out of balance
condition can be improved with the addition of a color extender. Remember to safety all gel slot
accessories.
