Coda TiRAY Guide

Coda Audio Rigging Maintenance V2.0 1
Coda Audio Rigging System’s Maintenance
The following general maintenance procedures apply to Coda Audio TiRAY and
TiLOW, rigging parts and accessories.
As there are some differences to certification and other local regulation requirements from
one territory to another. The following maintenance procedures are supplied as a guide to
general good maintenance of your rigging system. This guide should be studied in conjunction
with any local rules and regulations for your territory. This guide does not replace any local
rules and regulations and should not be taken as an overriding guide to any local rules and
regulations that you may need to adhere to in your own territory.
General:
All rigging parts, including cabinet fixtures and fitting, fly-bars, extension bars, shackles and
dollies should be fully inspected every 12 months. The owner of the equipment should set up
their own schedule for undertaking this work. It is recommended that the first general
inspection should be undertaken 12 months from date of first system use.
In addition to an annual inspection of all parts; Coda Audio recommends that a general visual
inspection of all parts should take place before each system is installed or used. A further
visual inspection should be undertaken at the end of each use. These inspections should be
performed by a suitably experienced and qualified system technician, and a log should be
kept of all inspections completed.
It is important to remember that the cabinet fixtures and fastenings form an integral part of
the overall suspension (flying) system. Therefore, great care must be taken when using,
transporting or storing your cabinets and accessories so as to avoid any physical damage,
either via hard contact with floors, walls or other equipment coming into contact with your
speaker cabinets and their accessories. Coda Audio provides a variation of transport dollies,
flight cases and soft covers to help protect your system, and these should be used at all times.
Coda Audio does not accept any liability or responsibilities for damage, how so ever caused,
to your systems or accessories at any time. Coda Audio recommends the use of the
accessories made available, at all times without exception. It is the responsibility of the
equipment “owner” to keep all equipment in good working order and for it to be used only as
intended, within its listed specification area of use. Should you have any questions relating to
the correct usage of the equipment, please contact your Coda Audio representative or Coda
Audio direct for further assistance and support. Contact information is listed at the back of
this document.
This document will only discuss and cover Coda Audio supplied products and accessories. This
document does not take into account any equipment which is used in conjunction with Coda
Audio products and accessories, such as chain motors, electric hoists, steel wire, shackles or
other rigging equipment.

Coda Audio Rigging Maintenance V2.0 2
Overview:
The correct usage of your Coda Audio system must be adhered to at all times. If you are
unsure of any point, it is always best to ask before you start using the system; this will not
only assist in a better understanding of your equipment, but also further your general
knowledge of Coda Audio systems.
This document is not a training manual. For any and all training related information, you must
contact your local Coda Audio supplier or Coda Audio Hannover Germany for further
information.
It is Coda Audio’s requirement that all systems will only be used by suitably experienced and
qualified individuals. This includes both the use of the system and its general maintenance.
Any and all test certificates that may be required for your territory must be obtained in
accordance with local rules and regulations; this is the responsibility of the equipment owner,
not Coda Audio or its local sales representatives.
Cabinets:
All Coda Audio line array cabinets are designed to be used in both ground stack and
suspended formats (using the appropriate accessories designed for these functions).
Your Coda Audio speaker cabinet (where applicable) has integrated steel flying hardware
which has been designed and fitted to the cabinet by Coda Audio during the manufacturing
process. All such flying hardware has been designed to perform its function in line with the
overall system design and specifications for use.
Example of integrated flying hardware
(Picture #1 TiRAY 3D view)

(Picture #3 TiLOW Side view)

Coda Audio Rigging Maintenance V2.0 4
These pictures show examples of the integrated flyware on cabinets designed to be
suspended either from a supporting Fly-Bar, Fly-Frame or from one another below the Fly-
Frame. The external and internal flyware parts have been designed from high grade steel,
which has been anti-rust coated and then painted with multiple coats of paint to its finished
level.
Normal wear and tear on all parts which form part of the connection process will result in
some paint being scratched and in time even worn off. This is normal and to be expected. It
will not affect the function of the parts or their construction.
(Picture #4 Example picture of TiRAY (used) inter-cabinet connection arm)
This picture shows an example of an TiRAY inter-cabinet connection arm after multiple usage;
slight surface to surface rubbing takes place as the arm is positioned into its “female”
corresponding position. Where the two surfaces meet, paint may be rubbed off. This is
normal. There is no need to repaint this urgently –this can remain as it is or be re-painted at
an annual inspection and service time.
Checks should be made to all metal to metal connecting surfaces, to ensure that no actual
hard scoring of the metal has taken place. Hard scoring only takes place when two metal
surfaces are rubbed together with excessive pressure on one or both surfaces. If evidence of
this is found on any two mating metal surfaces a full test and inspection is recommended.
Checks should be made to all metal work for any damage that may arise from cabinets or
other equipment bumping or banging into one another during transport, usage or storage.

Coda Audio Rigging Maintenance V2.0 5
Checks should be made for any larger signs of damage, such as may be caused by long periods
of transport where cabinets are not flight cased or dollied, or where other equipment may
come into contact with the cabinets. A simple visual check made by lightly running your hand
along the metal work, looking for scratches, pitting or other dents in the metalwork will show
up any problems easily.
Checks should also be made at the same time to all fixings and fastenings used to fix the metal
work to the cabinet.
fixings / fastenings
(Picture #5, #6 & #7 Typical examples of fixings / fastenings used on Coda Audio cabinet)
These fixings and fastenings should show no signs of movement, or be loose in any way; they
should be flush fitting to the metalwork surface. These fixings and fastenings are installed at
the Coda Audio factory and under normal conditions will not move. However, under some
long term transport conditions, particularly where roads are bad, long term vibration might
have an effect. Undertake a visual inspection at regular intervals. Once every 12 months
undertake a full manual check, as follows;
Check each screw fixing in turn using the appropriate tools (Coda Audio use a variation of
fixings / fastenings; Torx head –Allen key type and Cross Head) make sure you use the correct
tool format and size. Simply insert the tool into the fixing head, and apply a little pressure in
the clockwise direction. Normally there will be no movement and this indicates that the fixing
is tight and all is OK.

Coda Audio Rigging Maintenance V2.0 6
Torx Allen Cross head
(Picture #8 picture of the three type of fixing head used)
Do not apply greater pressure than 1 kg of test pressure. Do not attempt to force the fixing in
any way. Do not use air tools.
If any fixing or fastening is found to be loose, carefully tighten until the stop position is found.
Do not over tighten as this may lead to damage of the fixing threads.
If movement is found on any fixing, perform a full check to all metalwork and fixings on the
cabinet, as movement in one area normally indicates that the cabinet has been stressed in
some way and a full check is required. Perform a visual inspection first, followed by a fixings
inspection using the correct tool.
Flying Pins:
A specially designed Coda Audio retaining pin is always attached to its metalwork on the
cabinet and operates on a “Spring & Ball” system that does not come away from the cabinet.
This design has achieved a near zero loss of pins since its introduction. The pin works simply
by depressing the plunger and moving the complete mechanism forwards to lock and
backwards to unlock. Like all Spring & Ball systems once the pin is in place and the plunger
released, the pin will be locked in place. To remove the pin, depress the plunger and pull the
complete mechanism backwards, fully.
Regular visual inspections of the pins should be undertaken. Once every 12 months a full
physical inspection should take place, at this time inspect the pin for alignment and any
operational defects that do not allow free movement and operation.
It is vital that all pins are correctly secured during operational use, transport and storage. Pins
left un-secured will become a hazard to staff, and may also be damaged which must be
avoided.

(Picture #10 TiLOW side view)
Part number: Coda-Pin F TiRAY
These pins form a vital part of the flying system and its safe operation; they should be visually
checked at regular intervals for any damage or poor functionality.
Check the pin plunger is depressing correctly –check that when depressed the two ball locks
at the end of the pin, move into the body of the pin, and back out again when the pin plunger
is released.
Check that without the pin plunger depressed, the two ball locks are fixed in the “out”
position and will not go back into the body of the pin
Every 12 month run a full check on all pins for correct operation.

Coda Audio Rigging Maintenance V2.0 8
(Picture #11 TiRAY and TiLOW pin in transport position)
Always train staff to place the pins in this position when not in use, this will help protect the
pin from damage and will also keep the pin with the cabinet at all times. Pins which are not in
transport position may get knocked off or damaged in transit. This can cause delay at setup
time.
The pins supplied by Coda Audio are the correct specification for their designed usage, if you
lose a pin, please contact your Coda Audio representative for replacements; do not replace
with none Coda Audio parts.
Check regularly that the pins are in place, replace with original Coda Audio parts as required.
The TiRAY system also uses a separate retaining pin for the rear part of the flying system.
(Picture #12 TiRAY Rear Hardware pin)
Part number: Coda-Pin-R TiRAY

Coda Audio Rigging Maintenance V2.0 9
(Picture #13 Coda-Pin-R TiRAY in single cabinet transport position)
This pin is housed and used in various parts of the flying system and is also retained to the
flying system by a steel retaining wire.
The pin has a location home point when not in use as shown in picture #13.
Always make sure that all staff are trained to place these pins in the correct position when not
in use. The steel retaining wire is just to hold the pin in close proximity to its area of use.
Due to the nature of usage, it is possible for the steel retaining wire to become broken if
caught or snagged on something while the cabinet is being moved, the steel retaining wire is
made so that if it does become stuck or snagged in something it will break after a certain
amount of pressure, this is by design, as this retaining wire is only used for keeping the pin
with the cabinet. This retaining wire has no load bearing function; it must not be used for any
other purpose than retaining the pin to the cabinet.
Check regularly that the retaining wire and pin are in place, replace with original Coda Audio
parts only as required.
Never use damaged pins for operational use; this is unsafe and may lead to accident or injury.

Annual Inspection:
The annual inspection of your cabinet(s) should be formed of three parts
Visual inspection of metalwork and woodwork
Physical inspection of all metalwork and woodwork
Acoustical check of all components and electronics
We will only deal with points 1 & 2 in this document.

Coda Audio Rigging Maintenance V2.0 11
Point 1: run a visual inspection of all cabinets; clearly mark any cabinets that require attention
based on the visual inspection.
Point 2: run a physical inspection of all cabinets; this should include checking all metalwork,
fixings, fastenings and the cabinet woodwork.
Under normal conditions your cabinet(s) should require nothing more than a clean after all
testing has been completed.
Woodwork: The TiRAY and TiLOW wooden enclosures are covered with polyurea coating. This
material is especially designed to prevent any damage to the cabinet. Any kind of scratches on
the material can be touched up with HAMMERITE DIRECT TO RUST METAL PAINT SMOOTH
AEROSOL SDSHM106 BLACK (applied locally with a cotton pad). The cabinets cannot be
repainted by an end user. Polyurea painting requires specialist painting equipment and
techniques. Cabinets should be returned to Coda Audio GmbH if a complete polyurea repaint
is required.
Metalwork: The metalwork can be “touched-up” where scratches have occurred to maintain
good overall condition. As the metalwork is powder coated, please do not use any wood paint
on these parts. For small scratches, please use a paint marker or permanent marker. For
larger areas which require repaint, please use a black spray colour, colour code RAL9005.
In difficult climatic conditions of excessive heat, cold or humidity, a very light rub-over with a
light oil cloth on all metalwork can be advantageous, as this may help to reduce the effects of
oxidisation to the metal parts. Please be aware that any slight coating of oil might make
handling more difficult and will lead to slight oil deposits coming off on hands. We
recommend that if you are using an oil cloth rub-down on the metal parts, that you inform all
staff and users, so that they are aware and may take the opportunity to wear protective
clothing and take additional care when handling the cabinets and fly-bars.
Never allow any residual levels of paint, oil or cleaning fluids to build up on the surfaces of the
cabinet or its metalwork and accessories.
TiLOW and LINUS RACKS have transport “soft covers”. We recommend the use of these
covers at all times during transport and storage, they will help protect from knocks and bangs
and provide a good level of protection from dust, dirt and poor weather conditions.
Please note that in wet conditions cabinets and metalwork should not be allowed to stand in
soft covers for prolonged periods of time without being allowed to dry off naturally. If
cabinets become wet during use, they should be allowed to dry off as soon as possible.
Allowing any wood or metal product to stay wet for periods longer than 24 hours without
suitable ventilation will lead to oxidisation and potential mould taking hold. Always dry your
product off naturally, without forced heat, as soon as possible; this is should also apply to
flight cases.
Once dry, undertake a visual inspection of each system part and if required rub a lightly oiled
cloth over all metalwork.

Coda Audio Rigging Maintenance V2.0 15
For TiRAY systems, there is an option to transport 6 x TiRAY cabinets in specifically designed
flight cases; this is the recommended way of transporting the system. The most important
point here is that all rigging equipment must be cared for and transported correctly; failure to
do so may lead to accident or injury. It will definitely lead to a reduced life span of the rigging
system.
A visual inspection of all rigging hardware should be undertaken at regular intervals; and a full
inspection and test certification (as required) should be undertaken once every 12 months.
This inspection should be as already described, with the following additions.
Where fly-bars have been supplied by Coda Audio with “shackles” these may require local
territory certification, please check with your local authorities.
Where extension bars are used and the use of twin heavy duty nut & bold are the “fixing”
make sure all washers are in place –do not use without the correct washers and safety split
pins.
(Picture # 21 of large nut and bolt with washer as used on the EXBAR TR extension bar)
Where any safety pin is used; always make sure these are used and in place with the system,
failure to use these may lead to accident or injury.
Check these washers and safety pins are always in place and used each and every time the
system is used.
If any of these parts become damaged or are lost, you must only use Coda Audio replacement
parts as each item has a specification designed for its use, none replacement or replacement
from another source will compromise safety and could cause damage or injury.
It is vital that all parts of the flying system are only used up to the maximum load weight
permitted by design. Never overload any part of the system beyond the published
specifications. These specifications can be found for each system on the Coda Audio website
at www.codaaudio.com.
If you are unclear about the specifications of your system, please ask your local Coda Audio
representatives for assistance.
All flying accessories, for example, extension bars, must be transported in suitable flight cases.
While these parts are made from high grade steel and are normally designed using a 10:1
factor for safety reasons, care must be taken when in use, transport or storage, so that the

Coda Audio Rigging Maintenance V2.0 16
parts do not become damaged at any time. These parts have specifically designed connection
and operation points which are critically positioned and must stay so for correct operation to
take place. Avoid dropping any part onto any hard surface. Avoid miss-use or any use other
than their specific function. NEVER use tools such as hammers on any part of the system. If
there is a need to use a force greater than that of the human hand for any reason, only use
specialist tools with none metal heads.
If any part of the system is subject to miss-use or overloading or any form of stress tension,
the parts concerned and all those that might have been connected should be fully inspected
and if required, be load tested by a fully certified testing centre.
The design of all flying hardware parts has a high degree of accuracy making alignment of one
part to another very easy while minimising excessive tolerance. The connection point from
the fly-bar to the cabinet is such a critical point.
(Picture #22, #23 of Fly-bar to cabinet connection point for TiRAY)
This point is on the underside of the fly-bar, therefore when preparing a system for use, it is
natural to place the fly-bar on the ground; when the bar is placed on the ground it will rest on
the connection points. Make sure that the bar is not dropped or in any way placed heavily on
any hard surface, as this might lead to some deformity of the connection point which will
result in miss-alignment.
When checking your cabinets and flying system, always remember to remove any sticky tape,
(Gaffe or insulation tape) which may have been applied. The removal of residual tape or glue
will not only keep your system looking its best; it will also help stop the build up of dust and
dirt which will form on any sticky surfaces. A clean and tidy system is normally respected far
more than one which is seen as dirty!
