3 Physical Installation
This section of the Manual explains how to install the surface and the sub-sea components of the
Teledyne TSS 440 System.
During the installation procedure you should make a written record of certain parameters and retain
them with the survey log for reference during the post-processing operation. The DeepView for
Windows software on the SDC allows you to examine the System parameters and to create a printed
copy that you may retain with the survey records.
There are many different types and size of survey vessel and ROV and it would be impossible for this
Manual to cover all installation possibilities. The instructions in this section therefore represent a set of
general guidelines and recommendations that experience has proved effective.
3.1 Surface Display Computer (SDC) Installation
WARNING
You must take precautions to secure the SDC when you store and operate this
unit in its transit case. Protect personnel from the hazard of falling equipment and
protect the unit from damage when the survey vessel moves due to the action of
waves. Install cables away from walkways and secure them so they do not
present a hazard to personnel.
CAUTION
To avoid potential damage to the SDC, make certain it has sufficient ventilation to
dissipate the heat that it generates during normal operation. You might damage
the SDC if you allow it to overheat. To operate the SDC inside its transit case,
release and remove the lid of the transit case to allow effective ventilation and
heat dissipation.
If you mount the SDC in a 19-inch instrument rack you must allow a minimum
30mm clearance between the top of the SDC and any other equipment mounted
directly above it in the rack. Also, allow a minimum 100mm space between the
SDC rear panel and the rear of the instrument rack to allow for connectors and
cable routing.
Although the SDC uses solid state electronics, the hard-disk drive and parts of the display panel are
susceptible to damage through shock or sustained vibration. You must therefore exercise some care
when you select a suitable location for this unit:
❐ Install the SDC where you have easy access to the controls. Choose a position for the SDC
that allows you to see the screen easily while you operate the ROV.
❐ If you do not mount the SDC in an instrument rack, use the original SDC transit case to provide
shock protection for the unit. Secure the transit case so that it cannot slide or fall with move-
ments of the vessel.
❐ Make certain there is sufficient ventilation space above the SDC to remove the heat that it gen-
erates during normal operation. If necessary, use an electric fan to provide additional ventila-
tion.
