4 Adjusting the Set Angle between Two
CAD 208 Mid/High Enclosures
You have two options for adjusting the set angle between CAD 208 enclosures
- compression mode and fixed mode. In compression mode, the angle is easily
adjusted after the flown array is up and in place. This requires a lashing-strap or
chain hoist. In fixed mode, the angle is determined during setup and the flown
array cannot be adjusted later. This option does not require a lashing-strap or
chain hoist.
4.1 Compression Mode
Determine the set angle between two enclosures simply by adjusting the lower
Set Angle pin; the top pin always glides in the slot on the Link connector. This
way one person can easily curve the array.
The following angles may be adjusted between two CAD 208 enclosures: 0°,
1.5°, 3°, 4.5°, 6°, 7.5°, 9°, 10.5°, 12°, 13.5°, and 15°.
Fig. 12: The CAD 208’s set angle in compression mode is 4.5°
The rigging hardware is designed so that you can adjust the set angle on a
flown CADIS™ array; that is, after it has been hoisted.
How does this work?
The pin that determines the set angle is merely a predefined stop for the flexible
connector component when the entire CADIS™ array is compressed accordion-
style at the back and adjusted using a lashing strap or chain hoist. When no
force is exerted, the entire mid/high array is suspended at 0°, meaning that the
Set Angle pin is easily repositioned. kann verstellt werden.
Important note: The pin labeled Link connects individual CAD 208 cabinets. En-
sure this pin is inserted; otherwise the enclosures will not be connected to each
other and may swing forward!
4.1.1 Preparations
The following section describes how to set up an array in compression mode.
Use CADIS™ CAPS software to select rigging frame pick points for setting the
angles between CADIS™ 208 mid/high enclosures.
4.1.2 Mounting the Rigging Frame
It takes two people to perform these tasks. Remove the quick-release pins from
the rigging frame and the two pins on the back of the top CAD 208 enclosure.
Place the rigging frame on the enclosure. First attach the two front connectors.
Turn the rigging frame’s connector component down and slide it into the rear
rigging connector.
You may mount the top mid/high enclosure to the rigging frame in fixed or
in compression mode. To attach it in compression mode, insert the first pin
through the hole labeled Link on the enclosure and attach the connector com-
ponent by inserting the second pin through the slot into the hole labeled 7.5°.
To attach it in fixed mode, insert the first pin through the hole labeled 4.5° on
the enclosure and attach the connector component by inserting the second pin
through the slot into the hole labeled 7.5°.
Note: The maximum set angle for the top mid/high enclosure is 7.5°
(with the rigging frame set to 0°).
Fig. 13: Rigging frame set to 0°
Attach to the top rigging frame the shackle that will hold the motor’s hook. Your
choice of pick point depends on how sharply you aim to curve the entire array
later.
Note: Depending on application, you may not be able to select a pick point
with a shackle. In this case, use two shackles and a suitable O ring as shown in
Figure 14.
