Page 5: Chapter 1 - Introduction
The Purpose of the CD42 The CD42‟s primary purpose is to allow an operator to both track and locate pipeline pigs. A pipeline pig is a device that is usually made of solid polyurethane or a polyethylene foam and is often shaped roughly like a bullet. -
Page 6: Chapter 2 - Renter's Quickstart
Chapter 2 - Renter’s QuickStart This section of the manual is designed to be read by people who are using the CD42 for the first time and would like a quick overview of how the system is put together and how it operates. The CD42 has several advanced functions such as pig passage recording and pig speed calculation that cannot adequately be covered in a brief overview. -
Page 7: The Receiver
CD42 Pipeline Pig Location & Tracking System Remove the supplied connecting cable from the case and attach the proper end to the CD42-R receiver unit. The connectors on each end of the cable are “keyed” to the receiver and antenna connectors to insure that they will mate only in their proper orientation. -
Page 8: The Antenna
The Antenna The CD42-GP receiving antenna is quite sensitive, with a through-pipeline range of approximately 15 feet using our smallest transmitter. The GP also has a proprietary design that allows it to reject the magnetic noise produced by moving it through the earth‟s magnetic field. The benefit of this technology to the end-user is that he can walk and search for transmitter signals simultaneously;... -
Page 9: The Transmitter
All of our transmitters emit a magnetic field that passes through the pipeline and is received on the surface by our CD42- GP antenna and passed on to the CD42-R receiver unit. CDI‟s two most common transmitters are the CD42-T1 and the CD42-T2 (both of which are available for rental or purchase). -

Page 12: What To Look For While Tracking And Locating
CDI at the numbers on the title page of this manual. Pig Passages Normally a pig‟s progress through a pipeline is monitored by an operator with a CD42 receiver “leapfrogging”. This is the process of setting up in a location, waiting until after the pig passage has... -
Page 13: Stationary Or "Stuck" Pigs
The CD42 easily shows the operator the pig‟s passage at each location. When an operator sets up the CD42 receiver at a location to await a pig passage, he should orient the receiving antenna parallel to the pipeline. As the pig approaches the location and then moves away, it produces a distinctive wave shape on the display. -
Page 14: Conclusion
The remainder of this manual is dedicated to explaining in greater detail the more advanced aspects of the CD42 system, and should be read by anyone who plans to use the system for long periods of time, or who needs or wants to use some of the system‟s more advanced features such as recording and printing pig passage data. -

Page 16: Gain Buttons
CD42 Pipeline Pig Location & Tracking System The graphical display of the CD42-R allows us to show the pulses of the transmitter to the operator in the most intuitive way possible, and is the key to the CD42‟s ease of use. -
Page 17: Recording Pig Passages
Typical Help Screen for the Setup Button Recording Pig Passages The ability to record up to 99 individual pig passages is one of the CD42 receiver‟s most useful functions. The receiver has the ability to, in real time, analyze incoming magnetic signals against the known pattern of our transmitters. - Page 18 Note: Do not turn the CD42 receiver off during the recording process - always wait until the pig has passed and the unit issues the slower series of beeps to turn off the power. If the unit is turned...

Page 20: Automatic Record Mode
Numeric Location ID Automatic Record Mode When the CD42 is in automatic mode and the operator presses the RECord button on the main screen (Figure 23), the CD42 receiver unit will continuously monitor the incoming signals and attempt to automatically detect, count, number and record pictures of transmitter passages without an operator’s presence. - Page 21 “View a Recording File” on page 24. When the CD42-R detects a pig passage, it will emit a series of beeps to indicate to the operator that a pig recording session is underway. The display will change to read “Auto Recording” ( Figure 24) and the number of pig passes will also update to reflect the current pass.
-
Page 22: Manual Record Mode
RECord button in the lower left-hand button of the Main Screen (refer to Figure 23) the unit would begin recording a PICture file. The CD42-R would continue to record the same PICture file until the operator pressed the RECord button again to halt it, or the CD42-R had exhausted its internal memory. -
Page 23: File Menu
FILES button on the main menu. Refer to Figure 25. If there are any files saved in memory, then a list of those files will appear (shown in Figure 26). If there are many files (the CD42-R has the ability to store up to 99 PICs, or pig passages) , then they will fill the screen. If there are no recorded files saved in memory, then the FILES button will not activate. -
Page 24: View A Recording File
CD42-T1 transmitters should be traveling by within the next 24 hours. If the CD42-R is configured to record in automatic mode, each one of the pig passages will be recorded as its own PIC file without an operator being present. When the operator returns to the equipment 24 hours later, he merely selects the File Submenu to review the dates and times of all the PICs. -
Page 25: Tag A Recording File
When finished viewing the PIC file, simply press the Back button to return to the File Submenu. Pressing Back once more returns to the Main Menu. The PIC data will be available for viewing until the operator deliberately erases it. PIC data is not lost when the CD42-R unit is turned off. -
Page 26: Calculate A Pig's Speed
CD42 Pipeline Pig Location & Tracking System The list of available PIC files is displayed on the screen, each noting the time, date and Location ID of each pig pass. Using the up and down buttons, highlight the first file to be tagged. Pressing the File Tag button (Figure 31) places a plus (+) sign next to the tagged file (Figure 32). -
Page 27: Print A Recording File
CD42 Pipeline Pig Location & Tracking System The CD42-R will now use the data that was saved with the PIC file to calculate the pig speed. A screen similar to the one in Figure 34 will display the pig speed information. - Page 28 CD42 Pipeline Pig Location & Tracking System Once the printer is connected, powered on, and online the operator can proceed with printing any previously recorded PICtures. Using the same steps described earlier in „Viewing a Recorded File”, the operator selects a file to be printed by placing the highlight bar on the appropriate file.
-
Page 29: Setup Menu
In addition to printing a single file image, an option is available to print a list of all currently recorded pig passages. This option prints the recorded details for each file. It prints the time/date, the Location ID, the type of antenna , the gain setting of the CD42-R , and the duration of the recording. -
Page 30: Lcd Backlight
Back Icon LCD Backlight The backlight of the CD42-R‟s display is the greatest single electrical drain on the 5 D-Cell batteries. Therefore, turning the backlight off when not needed can significantly increase the life of the CD42-R system. The Light button (icon shown in Figure 40) allows the operator to manually turn the backlight of the display on or off. -
Page 31: Meter Display
CD42 Pipeline Pig Location & Tracking System Figure 40 Light Icon Often, in outdoor daylight the backlight is unnecessary, and in fact it is usually impossible to even tell if it is on. Because it can be difficult or impossible to tell if the backlight is on, there is a Dashboard icon that indicates the backlight‟s current status at all times. -
Page 32: Lcd Contrast
The system clock continues to run even when the CD42-R unit is turned off, so the operator does not have to set the clock every time the CD42-R is turned on. It will be necessary however, to occasionally set the clock. - Page 33 CD42 Pipeline Pig Location & Tracking System Pressing the Set Clock button gives the operator the screen shown in Figure 46 below. Figure 46 Clock Adjustment Using this screen, the operator sets the clock. The Back button accomplishes its normal task of moving back one screen.

Page 38: Connecting The Receiver To A Desktop Pc
Connecting the Receiver to a Desktop PC The CD42-R receiver has the ability to communicate to a desktop PC through the use of a standard RS- 232C communications link. This kind of connection is commonly referred to as a "serial connection" or "direct connection". - Page 39 Boot Output Text From the CD42-R As usual, you should press any one of the buttons of the CD42-R receiver to bypass the opening screen and begin using the system. While the CD42-R receiver is in normal operation, it continuously scans for the user to press the ENTER key on his keyboard.
-
Page 40: View/Transfer File Data
If these things seem to be correct, then verify that the batteries in the CD42-R are functioning, and that the power is turned on. If you still have problems, please feel free to contact the manufacturer listed on the title page of this manual for further assistance. - Page 41 Figure 61 Serial Interface File Transfer Menu The display changes to show the total number of recorded files in the CD42-R‟s memory. In the Figure 61 example, we have a total of two recordings, both from January 1 , 1996. Follow the onscreen instructions to select the recording that you are interested in.
- Page 42 Once the capture file has been named and opened by the terminal program, simply press ENTER on your keyboard again. The CD42-R will "dump" the data to the screen, which will also be written into the capture file. The data dump will normally look similar to Figure 63.
-

CD42 Pipeline Pig Location & Tracking System Figure 65 Data Plot Using Microsoft Excel Dump File Dates/Times The Dump File Dates/Times menu option works similarly to the View/Transfer Data File option (Figure 61). This time, however, only the number of the recording in memory, the date, the time and the mile marker position are dumped to the capture file. -
Page 44: View Transmitter Signal
View Transmitter Signal menu item and press ENTER. The CD42-R will prompt you with " Vertical display of antenna input. Press ENTER to start, any key quits." Once you begin watching the waveform, it is important to remember that any key will quit the operation, as no other prompting will occur. -
Page 45: Version/Statistic Info
Version/Statistic Info The Version/Statistic Info menu selection displays current information regarding the status of the CD42-R system, as well as contact information for CDI, the original manufacturer of the system. Highlighting and selecting Version/Statistic Info displays data similar to Figure 68. -
Page 46: Chapter 4 - Transmitters
All CDI transmitters emit a magnetic field that passes through the pipeline and any surrounding soil or water and is received by our CD42-GP. This signal is then passed along to the CD42-R receiver where it is amplified and displayed. A variety of different transmitters are manufactured to fit differing line sizes and applications from 2”... -
Page 47: Cd42-T2 (Figure 72)
CD42-T2 Replacing the Transmitter’s Batteries Remove the CD42-Tx transmitter from the carrying case and examine it. Notice that its only real distinguishing features are that it has one removable end (Figure 73), and a narrow grove that runs around its middle. The removable end is for the insertion of batteries, and the groove around the middle is to allow the transmitter to be attached to a metal bodied pig with the use of an optional flange kit. - Page 48 The transmitter should now be transmitting its magnetic signal. Please take a moment to verify that it is operating correctly by checking its signal with the CD42-R receiver. This step is especially important prior to launch – please do not launch a transmitter into a line without verifying that it is transmitting properly.
-
Page 49: Transmitter Patterns
Figure 78 Constant-On Mode Any of CDI‟s transmitters have the ability to be programmed with a pulse pattern that is completely configurable, and in addition have the ability to have a delay-on time programmed that can be as long as several months. These transmitters accomplish this by incorporating a very tiny computer that drives the electronics. -
Page 50: Mounting The Transmitter On Your Pig
T1 to be bolted to the body of a metal pig. Miscellaneous Pigs The CD42-T1 transmitter is designed to fit into, or be towed behind all types of pigs. Pigs that have been previously equipped with Pipeline Inspection Company‟s SPY transmitters are mount compatible with our CD42-T1 transmitter. - Page 51 CD42 Pipeline Pig Location & Tracking System Long-term storage of a transmitter is best accomplished by following the following steps: Remove the cap from the transmitter and remove all batteries from the battery carousel Ensure that the O-Ring and the O-Ring‟s mating surface have a thin film of a petroleum jelly such as Vaseline.

Page 52: Chapter 5 - The Antenna
Chapter 5 - The Antenna General Purpose Antenna The CD42-GP is the General Purpose antenna of the CD42 system. It has several aspects that make it the antenna of choice in the field. The CD42-GP rejects, to a great extent, the earth‟s magnetic field. What this means to the operator is that he can, for the first time with any pig tracking and locating system, walk at a normal pace and search for transmitter pulses simultaneously. -
Page 53: Chapter 6 - Tracking A Moving Pig
The operator should have a rough idea of the flow rate of the pipeline, and allow enough time between points to set up the equipment and begin looking for the pig. When an operator sets up the CD42-R at a location to await a pig passage, he should orient the receiving antenna parallel to the pipeline. -
Page 54: Leaving The Cd42 Unattended
Leaving the CD42 Unattended If the CD42-R is set up to record in Automatic mode, it can be used to detect pigs in an unattended fashion. This might be useful if an operator simply wanted to know if a pig, or any number of pigs, passed a certain location in the middle of the night. -
Page 55: Chapter 7 - Locating A Stationary Or Stuck Pig
“dots” across the lower part of the screen. If the Gain is turned down too low, the transmitter will not be located by the CD42-R receiver. If the Gain is turned up too high, the transmitter signal will be “hidden” in the noise. A Gain setting of 5-7 should prevent the operator from walking past the pig without locating it. -
Page 56: Pinpointing A Pig's Precise Location
Once the general vicinity of the pig has been located, it is now time to find the exact location of the pig. This can be done by switching the orientation of the CD42-GP antenna to an angle perpendicular to the pipeline (Figure 83). - Page 57 CD42 Pipeline Pig Location & Tracking System With the antenna perpendicular to the pig, an exact location can now be determined. The waveform signals will now be the reverse of a parallel orientation. As the operator moves the antenna closer to the pig the signal strength drops until reaching the null (Figure 84), or point of little or no signal, when the antenna is directly over the pig.
