Coda Audio CiRAY Rigging Maintenance 1
Coda Audio Rigging System’s Maintenance
The following general maintenance procedures apply to Coda Audio CiRAY and
SC2-F/ SCV-F, 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 CiRAY Rigging Maintenance 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:
Image 1: CiRAY 3D view

Images 3: SC2-F and SCV-F
The pictures above 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.

Coda Audio CiRAY Rigging Maintenance 4
Image 4: Example picture of CiRAY (used) inter-cabinet connection arm
This picture shows an example of an CiRAY 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.
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.

Coda Audio CiRAY Rigging Maintenance 5
Fixings / fastenings
Images 5, 6 and 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) 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.
Torx Allen
Image 8: Two types of fixing head used

Coda Audio CiRAY Rigging Maintenance 6
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.

Image 10: SC2-F/ SCV-F side view
Part number: Coda-Pin F ViRAY
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 months run a full check on all pins for correct operation.

Coda Audio CiRAY Rigging Maintenance 8
Image 11: CiRAY and SC2-F/ SCV-F 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 CiRAY system also uses a separate retaining pin for the rear part of the flying system.
Image 12: CiRAY Rear hardware pin
Part number: Coda-Pin-R ViRAY

Coda Audio CiRAY Rigging Maintenance 9
Image 13: Coda-Pin-R ViRAY 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 the image above.
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.

 Always run a full inspection of the cabinet(s) once every 12 months, check all rigging
metalwork and fixings for wear & tear, check for rust, check for alignment.
 Always check that no metal parts have become damaged in any way, this includes
bends (alignment to another part), corrosion via rust or other type.
 Check all “pins” are working and fully functioning regularly.
 Check all product labels, indicators and data labels are in position and not damaged,
replace any which are worn or missing.
 Do obtain spare parts only from your Coda Audio representative.
 Do flight case any accessories in suitable designed flight cases.
 Do use Coda Audio transport dollies / flight cases and soft covers.
Don’t
 Don’t forget to visually inspect your system before use.
 Don’t forget to visually inspect your system after use.
 Don’t forget to check all pins are in place and functioning correctly.
 Don’t use none Coda Audio replacement parts or accessories.
 Don’t over tighten “fixings / fastenings” when checking.
 Don’t allow lose items to be carried via any transport method, always pack correctly.
 Don’t allow un-skilled operation of any part of the system.
 Don’t over-load any part of the system.
 Don’t forget- “Safety First” whenever using the system.
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.
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.

Coda Audio CiRAY Rigging Maintenance 11
Woodwork: The CiRAY and SC2-F/ SCV-F 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.
CiRAY and SC2-F/ SCV-F 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.

You will find this general information and warnings on the following components on all
CiRAY accessories:
Image 22: General information and warnings on CGA
For CiRAY systems, there is an option to transport 6 x CiRAY cabinets on specifically
designed transportation and rigging Dollies protected with a transportation cover; 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 single pick point adapters in combination with the FR-AR and FRT-AR
are used make sure all pins are locked and are in place – do not use when pins do not lock
correctly!

Coda Audio CiRAY Rigging Maintenance 17

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
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.

Coda Audio CiRAY Rigging Maintenance 18
Images 24 and 25: Fly-bar to cabinet connection point for CiRAY
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!
