Coda TiRAY, TiLOW Maintenance Manual

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.

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.

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 Fly­Frame. 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.

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.

Torx Allen Cross head

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.
