12.1 “A DWNFLT-GTO”DOWN-FILL ACCESSORY TEST FORM ........................... 17



1 INTRODUCTION The aim of this manual is to enable users to use the “A DWNFLT-GTO” accessory (indicated hereafter as “downfill accessory”) correctly and take all the measures and have all the means necessary for safe long-lasting use of the entire system. The user is intended as being: the purchaser, site manager, personnel responsible for transport and flying, warehouse staff and/or those responsible for maintenance and operators involved in general. The down-fill accessory, used to extend the functions of a GTO Line array, consists in a main frame, fitted with a series of accessory components and intended to support a variable number of loudspeaker enclosures (a maximum of 5 Mantas or 4 Butterfly CDH483) dedicated to the coverage of the area nearest to the array, which will be called “down-fill elements”. The series of down-fill elements connected below the down-fill accessory will be called “down-fill array”. Thanks to its specially conceived design, it ensures the continuity of high frequency emission with the main GTO array, ensuring the utmost uniformity of sound reinforcement in the zones covered by the two sections of the complete array (Main and down-fill). This document must be kept by the person responsible, in a suitable place, in order to always be available for consultation. In the event of loss and/or damage, a new copy can be requested from Outline s.r.l. - Via L. da Vinci N° 56, 25020 Flero (Brescia), Italy. The rigging accessories described in this manual are manufactured, certified and marked in compliance with Community Directive 89/392/CEE, enacted with DPR 459 of 24/07/96 and later amendments 91/368/CEE, 93/44/CEE and 93/68/CEE. Interested parties are urged to read and divulge the instructions in this manual, in order to avoid damage to the system and incorrect use. Outline s.r.l. declines any responsibility due (for example) to incorrect use, use on behalf of inexperienced staff, use of non-original spare parts and unauthorized modifications. The user is also obliged to maintain the marking on the structure (name of manufacturer, year of construction, series/model) in good conditions.

This user and maintenance manual, which is an integral part of the suspension accessory, must be carefully read and understood before using the accessory.



2 DESCRIPTION

Figure 1 – Complete down-fill accessory

Very briefly, the down-fill accessory consists in: o a main frame o four brackets with quick-locking pins with buttons for connecting the main frame to the

bottom element of the GTO array; o two brackets for the rear connection of the first element of the down-fill array o two spring-loaded pins for fastening the rear connector brackets to the down-fill array o two front spring-loaded pins for fixing the front of the first element of the down-fill array

The main frame è built by assembling and welding a series of beams and plates, specially manufactured and finished in ENAW6082 aluminium alloy. The main frame fitted with its accessory components has been designed for use for Flying loudspeaker enclosures: i.e. with the loudspeaker enclosures suspended below it.

2.2.3 ID Plate

The product’s ID plate (Errore. L'origine riferimento non è stata trovata. ) is mounted on the main frame of each down-fill accessory.

Figure 3 – Down-fill accessory ID plate.

In particular, the ID plate features the , symbol, the manufacturer, the serial number of the down-fill accessory, its year of manufacture, the working load limit and the weight of the unit itself, including all the accessories (shackles, pins and brackets), which is 23 kg.

It is absolutely forbidden to modify, alter or tamper with the component’s ID plate.



N.B.: The accessory components supplied with the st ructure are chosen according to the overall capacity and the resultant stress; so, to establish the working load, reference must only be made to the ID plate on the downfill accessory, not any marking that may be on individual accessories.

2.3 Use foreseen It must be noted that, as foreseen by Italian law 626 and by DPR 547/55, staff members responsible for the use of the downfill accessory, as well as those involved in the work of rigging/flying the loads, must be trained according to UNI ISO 9926/92.

The maximum efficiency of the rigging accessories depends on the following instructions being followed: o learning the concepts contained in this manual; o before carrying out any movement, make certain the path and lifting area are free of

obstacles; o check the suitability and marking of all the accessories used for lifting the load; o raise the load smoothly and without jerks or abrupt acceleration; o warn before beginning any movement; o always check the total weight to lift and in particular that the loudspeaker enclosures are

those for use specifically with this rigging equipment; o use the controls in a smooth manner, avoiding thrusts or jerks; o wear protective clothing in compliance with safety regulations; o do not remain in the area below or near the load.

It is absolutely compulsory to use personal protection devices, such as gloves and footwear with reinforced toecaps and correctly identified with a CE symbol.

2.4 Criteria for use For excellent safe use of the downfill accessory, follow the following instructions carefully: o follow the instructions contained in this manual scrupulously; o carry out the periodical checks meticulously (see chap. 8 on page 14); o check the correct connection of all the accessory components

(shackles, pins and brackets) and the elements of the suspended down-fill array;

o only use accessory components provided with the product o if the downfill accessory is stored awaiting future use, make certain it

is positioned in a steady manner, so it cannot move or fall, and ensure that it is accurately checked before being used again;



2.5 Unforeseen use The foreseen method of use is the only one allowed by Outline s.r.l. and it is forbidden to use the downfill accessory for applications other than those for which it was designed: suspending/flying the specific loudspeaker enclosures. Any use other than that indicated is absolutely for bidden. More specifically, for correct use of the equipment, the following is

strictly prohibited: o lifting loads that are heavier than indicated on the ID plate; o transporting people; o lifting loads when people are passing in the surrounding area; o submitting the array to swinging or lifts that are not smooth; i.e. carried out with “jerks”; o allowing the rigging equipment to be used by unqualified or insufficiently trained staff; o lifting elements fixed to the ground or to other elements that are not part of the array; o leaving the suspended load unattended; o using the downfill accessory if it has no ID plate; o hitting adjacent structures with the load; o changing direction abruptly; o carrying out structural modifications to the downfill accessory, its accessories or any

other element of the array; o carrying out welding or repairs and/or connecting other accessories to the elements of

the structure or to the downfill accessory; o subjecting the structure to corrosive vapours and/or liquids; o subjecting the structure to temperatures of over 100°C; o subjecting the structure to a saline and/or an aggressive environment; o carrying out maintenance work on the structure without having removed it from service; o having maintenance work carried out by untrained staff.

3 Installation and dismantling

Installation and dismantling work are potentially very dangerous operations, so the utmost attention must be paid to the indications

in the following stages. To install a down-fill array below a GTO array, the following instructions must be scrupulously followed. The key terms included in the instructions and their meanings are indicated:

o Down-fill accessory: Adaptor accessory made up of a main frame and accessory components for suspending a down-fill array

o Down-fill element: electroacoustic system used as an element of the down-fill array o Down-fill array: A group of down-fill elements connected in series and suspended

below the down-fill accessory.



3.1 Installation procedure sequence: To lock the front and rear spring-loaded pins, when indicated in the following sequence, turn the knobs clockwise. When the system is installed, all safety devices mu st be enabled. Only unlock before carrying out dismantling work.

1. Position the down-fill accessory as shown behind the last GTO element of the main array

2. Insert the rear GTO connector brackets in the appropriate spaces



3. Insert the pins with locking buttons (one on either side) in the appropriate holes

4. Withdraw the front connector brackets of the last GTO element of the main array and

set the required splay angle between the main array and the down-fill array. 5. Swing the down-fill accessory forward in such as way as to enable the front

connector brackets of the last GTO element of the main array to enter the appropriate slots



6. insert the pins with locking buttons (one on either side) in the appropriate holes

7. If they are not already installed on the down-fill accessory, fit the accessory’s rear connector brackets and tighten the pins into the safety position, turning the relative knobs clockwise.

8. Connect the down-fill accessory’s rear connector brackets to the rear connector hardware of the Mantas (or Butterfly) enclosure.



9. Swing the down-fill element (Mantas or Butterfly CDH483) forward, holding the spring-loaded pins on the front part of the down-fill accessory open, so that the pins can be released and inserted in the side holes of the down-fill element.

10. Turn the knobs clockwise to tighten the pins into the safety position. 11. Proceed with the installation of the other down-fill array elements using the standard

procedure for installing Mantas (or Butterfly CDH483) arrays.

3.2 Dismantling procedure sequence: To unlock the front and rear spring-loaded pins, turn the knobs counterclockwise. Only unlock when indicated in the dismantling proce dure sequence. When the system is installed, all safety devices must be enabled.



Work for dismantling the down-fill array is carried out beginning with the last down-fill element (the lowest). As far as the down-fill elements are concerned, dismantling procedure is similar to that for dismantling a normal Mantas or Butterfly CDH483 array.

1. Position the entire array in such a way that the last down-fill element (the lowest) is at a height of approximately 1 metre from the floor/ground.

2. Withdraw the side connector brackets (left and right) that connect the last two down-fill elements, supporting the front part of the last down-fill element (the lowest) with a hand, gripping the front handle. To withdraw the brackets, it is necessary to unlock the safety device on the fixed bracket of the down-fill element by sliding the milled grip of the actual device upwards.

3. Once it is disconnected at the front, swing the down-fill element down, so that the front is facing the base of the transport trolley or the floor/ground.



4. When a transport trolley is available, lay the down-fill element on the trolley. 5. Turn the knobs of the rear spring-loaded pins of the down-fill element

counterclockwise to unlock the safety device. 6. Withdraw the rear spring-loaded to definitively disconnect the down-fill element from

the rest of the array, disconnecting the (left and right)rear connector brackets. 7. Repeat operations 2 to 6 until the down-fill element connected directly to the down-fill

accessory is reached 8. Turn the knobs of the rear (left and right) spring-loaded pins of the down-fill

accessory counterclockwise.

9. Withdraw the front (left and right) spring-loaded pins with one hand, supporting the front part of the down-fill element with the other, gripping the front handle.

10. Swing the down-fill element down so that the front is facing the base of the transport trolley or the floor/ground

11. When a transport trolley is available, lay the down-fill element on the trolley.



12. Turn the knobs of the rear (left and right) spring-loaded pins of the down-fill element counterclockwise.

13. Withdraw the rear spring-loaded pins to disconnect the down-fill element from the rest of the array, disconnecting the rear connector brackets

14. Withdraw the front pins with locking buttons (one on either side) from the appropriate holes.

15. Swing the down-fill accessory downwards, accompanying it with one hand.

16. Withdraw the rear pins with locking buttons (one on either side) from the relative

holes to completely disconnect the down-fill accessory from the main GTO array.

17. Replace all the accessory components in their travel positions. 18. Place the down-fill accessory in a safe steady position.



4 NOTES

4.1 Connector pins Assembly of the main GTO arrays and the down-fill accessory is carried out with quick-action connector pins. It is important that they are correctly positioned, i.e. fully inserted, so that the locking balls are completely in working position (the locking button must be completely out/released).

5 PACKAGING The structural parts of the down-fill accessory are packaged and the accessory components provided fixed to it.

6 TRANSPORT Transport must be carried out by qualified personnel, to ensure that the material is handled correctly. The down-fill accessory must not receive bumps or impacts: in particular, the frame must be kept away from other weights that, if laid on it, could bend or damage it. For each of these operations, appropriate personal security/protection devices must be used.

7 CHECK ON ARRIVAL When the goods arrive, check their conditions against the shipping/freight documents, make certain no items essential to the installation (e.g. pins, brackets, etc.) have been removed; should this be the case, inform the transport company and the manufacturer.

8 MAINTENANCE & CONTROL The down-fill accessory’s excellent efficiency and good preservation are ensured by careful maintenance, but this is not synonymous with perfect operation. In fact, correct use, work intensity and the environment itself are decisive.

Ordinary maintenance includes: o visual control of all the down-fill accessory’s components for

obvious defects; o assembly and handling tests.

These operations must be carried out by qualified staff prior to every time the equipment us used. Any irregularity must be reported and work stopped.



8.1 Periodical control

The equipment and accessories must be regularly tested by expert staff, at least once every three months.

Checks and tests must be carried out on the structure and the accessories provided with it (pins, brackets, etc.) and must be reported in a special register (see example in Annex 1). This register must be kept up to date, entering the results of the tests and checks, and must be signed by the person who actually carries out the tests. In the event of any “irregularity” occurring, use of the device must be stopped, to enable an accurate examination to be carried out by expert technicians. Various types of “irregularities” can occur. This following is just a list to facilitate their possible identification; it must also be noted that these defects may also occur simultaneously. The main ones are: o oxidation and/or corrosion – widespread or limited to an element; o fatigue cracks or localized buckling; o buckling/deformation of the structure or elements (for example the ovaling of pins’ and

pinions’ holes, bending of brackets, etc.); o wear (for example of pins, pinions or contact zones); o damage of protective surface treatment, probable sign of an underlying crack; o etc.

The register must always be at the disposal of the authorities responsible for controls. In particular, the following checks must be carried out on the rigging accessory: o overall structure and, in particular, elements’ welding; o ovalization, deformation and/or cracks in the pin/pinion holes; o conditions of fixing pins and pinions.

9 REMOVING FROM USE In the event of even just one of the following list of defects being found in any component of the down-fill accessory, it must be immediately removed from use: o cracks in any element of the structure; o permanent deformation of the load-bearing structures; o non-compliant results of the checks carried out.

10 DISPOSAL AND SCRAPPING If any component has to be scrapped for any reason, disposal must be carried out by authorized companies and in compliance with current regulations regarding this matter. Take into consideration the fact that the accessory is manufactured prevalently in aluminium.



11 MAINTENANCE REGISTER As anticipated in the MAINTENANCE & CONTROL chapter, for every down-fill accessory and each of its components, a special register must be kept, in which the periodical tests that the structure and relative accessories undergo will be noted. An example is shown in Annex N°1.
