4-17 for instructions to change the analogue output settings. 3.1.1 Sub-sea Installation The care that you take when you install the sub-sea components of the 440 System will have a significant influence on the accuracy of survey data. Read the following instructions carefully and ensure that you have all the necessary parts and tools available before you attempt to install the System.
Page 36 ROV. ❐ Locate the housings so that you may route the cables easily between the sub-assemblies of the 440 System. ❐ Do not apply sharp bends or other mechanical stresses to the cables during installation or operation.
Page 37: Coil Array
NOTE You should read this section before you attempt to install the array of search-coils. These details are critical to the successful operation and performance of the 440 System. Follow these instructions carefully to obtain the best performance from the System and to avoid interference with other equipment on board the ROV.
Page 38: Search-Coil Configuration
3 – Physical Installation 3.1.3.1 Search-coil Configuration The standard 440 System uses three search-coils of dimension 1.0m × 0.94m × 0.03m. They must be mounted so that the sides without mounting holes point in a fore-aft direction. NOTE Versions of the 340 System used search-coils of different dimension. Do not use type 41 or other old coil types with the 440 System.
Page 39: Figure 3-4: Coil Separation Distance
NOTE Based upon considerable field experience, Teledyne TSS recommends a front- mounting location for the coils of the 440 System. This is both effective and practi- cal for the majority of installations. The preferred position to mount the coil array is on the front of the ROV. This will help the pilot to follow the most effective course along the target by using the DeepView for Windows Run Window.
Page 40: Coil Assembly And Installation
ROV. 3.1.3.3 Coil Assembly and Installation You must use the correct non-conductive mounting components supplied with the 440 System to fix the search-coils to the ROV frame. These mounting components include six pre-drilled cast nylon beams and nylon threaded stud, nuts and washers.

Page 45: Altimeter
Note that it is the position of the altimeter that causes these errors. Measurements of vertical range made by the 440 System will retain their accuracy under all normal conditions. NOTE Do not place the altimeter at the opposite end of the ROV to the coils. If you do not follow this advice, it is possible that the survey data might contain errors caused by pitch of the ROV or uneven seabed topography.

Page 49: Ground Connections
4 – Electrical Installation 4.1.1 Ground Connections If you provide the 440 System with an inadequate ground connection, parts of the System will act as ‘sacrificial anodes’ and will slowly decay during sub-sea operations. This will occur whether or not you use the 440 System.
Page 50: Power Requirement
It is very important to provide a good ground connection on pin number 2 of the cable. A poor or a missing connection will severely degrade the performance of the 440 System. You must make all connections to the ROV using waterproof connectors or splices of good quality.
Page 51: Sub-Sea Electronics Pod
On one end cap: ❐ Connection ports for coil channels 1 to 4. A label identifies the four coil channels. The 440 Sys- tem uses only three channels during a survey. You must ensure the unused port has a blank- ing plug fitted to protect it during sub-sea operations.

Page 55: Table 4-4: Ideal Twisted Pair Characteristics For Successful Communication
The SDC10 uses the 15-way D-Type labelled ‘COMMS FROM SEP ‘to communicate with the 440 SEP. This connector is internally linked to ‘COM1’ used by DeepView to establish communication with the 440 SEP. There is no requirement to make an external connection to link the SDC10 and 440 SEP comms.
Page 56: Table 4-5: Power And Communications Cable - 2-Wire Current Loop Connections
To use current-loop communications you must reserve either one or two conductor pairs in the ROV umbilical for the exclusive use of the 440 System. The System includes a cable that you should use to connect the ‘COMMS FROM SEP’ port on the SDC to the twisted pairs in the ROV umbilical. The cable has a 15-way D-type connector for connection to the SDC ‘COMMS FROM SEP’...
Page 57: Alternative Communication Methods
RS232 communications. This method of communication is only suitable for use with umbilical cables up to 15m. To configure the 440 System to use an alternative communication method, you must change link settings inside the SEP and the position of the external switch on the SDC comms enclosure.

Page 114: Establishing The Survey Configuration
6.3.1 Establishing the Survey Configuration 6.3.1.1 Target Scaling Target scaling is the method used by the 440 System to determine the relationship between the coil signal strength and the range to the target. It allows the System to know whether a specific signal level comes from a small target close to the coils or a larger one farther away.
Page 115: External Logging Format
Enter a positive value if the altimeter is higher on the ROV than the search-coils. If you have no altimeter fitted to the 440 System and your ROV allows you to set the coils at a fixed altitude above the seabed, enter the fixed altitude value.

ROV off the deck. Power-on the 440 System and allow a period of about five minutes for the System to settle. If the ROV is resting on the deck of the survey vessel, the proximity of the deck and other metal fittings will cause the search-coils to saturate.
Page 118: Background Compensation And Monitoring
6 – Operating Procedure 6.3.3 Background Compensation and Monitoring To ensure that information acquired by the 440 System is accurate, you must perform the full background compensation 20 minutes after you immerse the System in water and turn on the for the dive.
Page 119 System completes its final set of measurements. The background compensation results used by the 440 System are those included in the last line on the display. Examine the columns of figures that appear under each of the three channels. Within each of the used channels, the column of figures should all be the same within ±5µV.
Page 120: Seawater Compensation
6.3.4 Seawater Compensation The 440 system is based on being able to separate the different signals arising from seawater and target. This allows the range to the target to be determined from two coils. This is achieved by means of a signal processing routine, which differentiates the target signal from the unwanted seawater signal on the basis of its slower decay rate.
Page 121 If you have connected an altimeter to the System, the SDC determines the state of target burial by performing the simple calculation: COV = VRT – ALT A positive value for COV indicates that the target is covered. DPN 402196 Issue 4.1 © Teledyne TSS 6- 17...

Appendix A describes the principle of Pulse Induction used by the 440 System. This method detects and locates any conductive material within range of the coil array.

Page 152: Speed Of Operation
7.3.2 Altitude above the Seabed The vertical detection range of the 440 System is limited by the characteristics of the target, in particular its size. The low signal strength that the System receives from a small target will reduce its detection range. If you use the System to survey a small target you should therefore operate the ROV as near as possible to the seabed, while avoiding damage.

Page 163: Update Rate
Update rates available from independent seabed profiling systems may be different from the update rate you have set for the 440 System. If your ROV includes both these systems, you must allow for their different update rates when you analyse the survey data.
Page 165: Maintenance
9 Maintenance You will find it easier to identify and clear a fault on the 440 System if you have a full understanding of the location of the individual sub-assemblies, and of the way they interact. This section helps you to maintain and service the System by describing the main internal components of the sub-sea installation.
Page 166: Power Supply Pod
Power for the sub-sea installation comes from the ROV electrical supply. Normally this will be nominal 110V single phase AC rated at 350VA. For special applications, Teledyne TSS can supply the 440 System with a PSU that accepts nominal 240V AC instead.

SEP unit. NOTE When opening the sub-sea housing Teledyne TSS recommend that you use screws inserted into the drilled holes to jack the endcap off. Under no circum- stances should a screwdriver (or similar) be used to lever the endcap off as this will result in damage to the o-ring seal and the casing.

Page 169: Communications Loop
When you configure the System to use the 2-wire current-loop communications method, the SEP and the SDC share a twisted pair in the umbilical. To avoid possible contention, the 440 System assigns ‘Master’ status to the SDC, and ‘Slave’ status to the SEP.
Page 170: Surface Display Computer
Many components within the SDC are susceptible to damage due to electrostatic discharge. You must take precautions against such damage: These precautions include the use of a grounded conductive mat and wrist-strap. Teledyne TSS will not accept responsibility for any damage caused by failure to take such precautionary measures.

Page 219: A Operating Theory
The System uses a simplified scaling procedure that allows a high degree of measurement accuracy and stability. This appendix describes the technique of Pulse Induction, and the method used by the 440 System to derive the signal strength and the target co-ordinates.
Page 220: Waveform Measurement
After the initial voltage peak, the shape of the decaying waveform will depend upon the nature and the proximity of any nearby conductive material. The 440 System uses this feature to determine the range between the coil and the target.
Page 221: Timing
The 440 System waits for a further 100µs to allow the voltage spike to decay and to allow the effects of sea water to dissipate. The System then begins a 1200µs sampling period as shown at Figure A-2(c).
Page 222: Derivation Of Signal Voltage
A – Operating Theory how the 440 System derives the signal voltage from these measurements for use in the calculation process. The SEP applies this measurement cycle to each channel sequentially as shown in Figure A-3. The measurement cycle for each channel lasts a total of 3125µs. With measurements repeated on four channels, it follows that the SEP measures each channel every 12500µs, or 80 times per second.
Page 223: Compensation: How It Works
Figure A-4: Seawater signal The seawater signal, to the 440's search coils, looks similar to a target. This means that as the vehicle is lifted off the seabed, a voltage over and above the target signal is seen. This voltage could easily be interpreted as a change in the target's position.
Page 224: Background Compensation
The “x scale” and “y scale” values can be decreased to zoom in on the graph, but should immediately returned to 150 and 1000µV respectively. This ensures that the © Teledyne TSS DPN 402196 Issue 4.1...
Page 225: Figure A-5: Perfect Lift With The Results Passing Through The Origin
Figure A-8 shows another effect due to the coils moving as the vehicle was lifted. The vehicle was not lifted smoothly, resulting in missing points in the middle of the graph. DPN 402196 Issue 4.1 © Teledyne TSS A- 7...
Page 226: Checking The Rejection
The Teledyne TSS 440 system operates at much greater survey ranges and this places stringent requirements on the background compensation and the rigidity of the coil mounting frame.

The two coil calculation is also able to adapt to the position of the target, using the centre and one other coil at larger lateral ranges. DPN 402196 Issue 4.1 © Teledyne TSS A- 11...
