4. SYSTEM INSTALLATION
4.1INTRODUCTION
The VARIANT 25A unit can be installed in a
number of ways. Typically several VARIANT 25A units
would be assembled to form a line array cluster, but it
can also be used alone, as a frontfill or as an under-
balcony unit. A wide range of accessories and uses
are available, and have been described in the
paragraphs below.
4.2 PLANNING/INSPECTION
4.3 INSTALLING A LINE ARRAY
SYSTEM
Whenever a cluster of only VARIANT 25A
units is to be assembled the procedure will be as
follows:
First step will be to attach the AX-V25
bumper to the hoist. The chain sling needs to be
attached to the structure using the shackle provided
with the grid. The shackle will be inserted into the hole
recommended by the EASE FOCUSsoftware.
The next step will be to mechanically
connect the first VARIANT25A to the AX-V25. In order
to do so rotate the connecting links (1) and then insert
the safety pins through the labeled holes to select the
splay angle between the VARIANT 25A and the grid
(2). Now both connecting links must be inserted into
the receptacles on the AX-V25 (3). Once this has been
done two more safety pins have to be inserted to
secure the boxes (4). It is highly advisable to check
thatall of the safetypins have been correctly inserted.
Before installing the VARIANT 25A system
it is advisable to run a simulation using the EASE
FOCUS software utilizing the venue dimensions. This
way we can determine the needs that should be met
by the rigging structures such as hoists, cranes,
beams, rigging points, etc. Besides providing weight
information, the program also provides users with
splay angle information, safety pin positions and
coverage predictions.
It is extremely important to assure that each
and every one of the aforementioned structures is
capable of supporting a superior load than that of the
completesystem.
Inspection is the next step after planning
and acquiring all the necessary parts needed to
elevate the systems. All parts, including the hardware
attached to the enclosure, the safety pins, etc. should
be thoroughly inspected before each use. Units
exhibiting deformations, cracks or any other defect
shouldbe replaced with newunits.
It is important to establish an inspection
routine for the complete rigging system before each
event or installation as well as establishing the
maximumload specifications of thehoists to be used.
Rigging should be carried out by experts
familiar with the way the system functions and their
characteristics.
On occasions it may be convenient to have
additional tie down points to impede the array from
twistingor swinging.
