6.3.4 LOCKING PINS
Certain array configurations and array tilts can collapse the splays between KF730 enclosures. This is
more likely to occur the more the array is curved relative to its length. The reason this happens is the
center of gravity for those enclosures ends up being forward or rearward of the suspension point(s). In
these cases, the Locking Pins should be used.
When ground-stacking, creating splays between enclosures requires the
use of locking pins.
Locking pins are inserted in the Hinge Tubes at the top of an enclosure
through the hole in the part of the Hinge captive to that tube and below
the hinge knuckle. This prevents the Hinge from receding down into its
own Hinge Tube, which is what happens when the splay between two
enclosures collapses. The KF730 Wizard will indicate when locking pins
are likely needed.
CAUTION: When tilting the array while rigging or unrigging enclosures,
unexpected collapse of the splays can occur because of shifts in the
array's center of gravity. To prevent this, It is recommended to always
use locking pins as described.
6.4 SETTING THE TILT ANGLE FOR THE ENTIRE ARRAY
Normally, the easiest method is to use a clinometer, such as a simple, bubble-type angle finder (pictured).
More sophisticated, albeit more expensive, electronic clinometers can also be used.
Place the angle finder against one of the rigging tubes on the face of the
uppermost enclosure in the array that can be physically reached. Using the
aiming angle for that enclosure listed in the KF730 Wizard, adjust the angle of the
entire array so that the face this enclosure is set at its prescribed aiming angle.
