Buried Cables And Pipes

Transmitter Connections

Perform a battery test. Use one of the following three methods to produce a trace signal
on the target pipe or cable.

Direct Connect Method

Plug the direct connect cable into the output jack [T-6] of the transmitter. Connect the
black clip to the ground rod. Place the ground rod in the earth perpendicular to the
suspected cable/pipe path. If necessary, extend the black lead with the Ground Extension
Cable (#9043 available separately).

1. Remove the ground bonding and attach the red clip to the shield of the cable, pipe,

or target conductor. (If locating power cables, the red clip can be attached to the
transformer cabinet, or the meter box).

2. Turn the transmitter on by pressing Ohms [T-2]. The continuity of the circuit will be

measured. The results are displayed [T-4] in ohms and as a tone.

− If the continuity of the circuit is very good (the reading on the display is less
than 3K Ω. and a solid tone from the transmitter is heard) all frequencies can be
used to locate. Always use the lowest frequency available. Lower frequencies are
less likely to ‘bleed over’ to other cables in the same area, and are very good for
tracing over long distances.

− If the circuit reads more than 3K Ω., but less than lOK Ω (indicated by a beeping
tone from the transmitter) it will be necessary to use a higher frequency than 512
Hz or 577 Hz in order to locate the cable/pipe.

− If the circuit reads more than lOK Ω., it will be necessary to use an RF signal
such as 33 KHz or 133 KHz.

− If there is no tone and the transmitter indicates that there is an open circuit (OL
in the display) this could be an indication of a poor ground, or an open-ended
cable or pipe. Use one of the higher frequencies available, at high level. If it is
an open-ended cable or pipe, the receiver's response will decrease suddenly at
the site of the clear or severed end.

78-8130-6151-8-E 15

Note: In the ohms mode, the transmitter can detect voltage as well as ohms. If a low
voltage is detected, the display will alternate between displaying ohms and volts. When
displaying ohms, the flag over the Ω symbol will be visible. When displaying volts, the
flag over the ‘V' will be visible. When the voltage magnitude is sufficient to impair the
accuracy of the ohms measurement, only voltage will be displayed. If the voltage is
AC, a sine wave will be visible on the display [T--4]. If a high AC voltage is detected, a
rapid beeping tone will be heard.

3. Press the Trace [T-3] repeatedly until the desired frequency appears on the display.

4. Press Output [T-5] to select high output level for longer tracing distances or deep
pipe/cable.

Dyna-Coupler Method

1. Connect the Dyna-Coupler to the transmitter output jack [T-6] using the coupler
cable (9011).

2. Clamp the Dyna-Coupler around the cable or pipe, below any bonds, just before it
enters the earth. The jaws of the coupler must fully close.

3. Press Trace [T-3] to turn on the transmitter. Press again to select 8 KHz, 33 KHz or
133 KHz.

Note: When using a Dyna-Coupler, always select high output level by pressing the
output key [T-5] on the transmitter.

16 78-8130-6151-8-E

Induction Method

If you cannot make a direct connection, or use the 3M

™

Dynatel™ Dyna-Coupler clamp

to apply a locating signal on the target, use the induction method. This method uses the
internal coil of the transmitter to generate a magnetic field. This is the least preferred
method of applying a signal on a target conductor because it can easily be picked up by
other non-target conductors in the area. However, it is the preferred method of applying
a signal to multiple cables/pipes in the same trench, and for the ‘two-man sweeping’
application.

1. Verify battery level of transmitter and remove any cables from the output jack.

2. Position the transmitter over the target facility with the hinge of the transmitter over
and in line with the cable/pipe path.

3. Align the Induction Direction arrows on the transmitter with the target conductor.

4. Turn on the transmitter by pressing the Trace [T-3] key.

5. Press Trace [T-3] again to select 33 KHz or 133 KHz.

6. Select High Output level for the best signal-to-noise ratio.

7. Trace the signal path with the receiver using the Induction Peak mode.

The induction mode of the receiver is a mode in which the upper antenna of the receiver
is tuned to minimize distortion from the magnetic field of the transmitter.

Note: The receiver must be at least 25 feet away from the transmitter to begin tracing
the target path.

78-8130-6151-8-E 17

Receiver Modes

Directional Peak

MODE + Directional Peak (DirPk) [SK Toggle]

In DirPk mode, four peak antennas are used to analyze the magnetic field pattern. The
bar graph indicates signal strength and the directional arrows sense the edges of the
magnetic field. The left/right arrows will indicate the direction to the nearest cable that is
in-line with the receiver handle.

As the antenna crosses the cable or pipe, the receiver speaker volume increases to a
maximum, the bar graph [1l] fills from both sides toward the middle, and the numeric
signal strength [10] increases. As the antenna moves off the target path, the speaker
volume decreases and the bar graph opens. Use the bar graph and the numeric signal
indicator to locate the exact target path.

Left of Target Path Directly Over Target Path

Once the target path has been located, the arrows at the top of the screen will indicate
the location of the target path in relationship to the receiver.

Note: When field distortion (due to congestion) is affecting the receiver the left/right
arrows may not coincide with the bar graph. Use the maximum numerical signal
strength to target the cable or pipe.

Right of Target Path

Directional Null

MODE + (DirNull) [SK Toggle]

In DirNull mode, as the operator approaches the cable or pipe, the numerical signal will
increase then fall sharply as the receiver crosses the target cable or pipe. The bar graph
fills from both sides toward the middle and the receiver speaker volume decreases. As
the antenna moves off the target path, the bar graph opens, the signal strength increases,
and the speaker volume increases. Gain adjust is automatic in DirNull mode.

The center of the DirNull screen provides a ‘compass view' of the target path. An arrow
will point toward the location of the cable/pipe in 45-degree steps. A solid line will
appear over the cable/pipe, indicating its orientation to the receiver handle.

18 78-8130-6151-8-E

For example:

Figure 1: If the target path is to the right of the
receiver, and running parallel to the operator, the
right arrow will display.

Figure 2: If the target path is to the left and in front
of the operator (not running parallel to the receiver)
the arrow will point toward the top left side of
the screen.

Figure 3: When the receiver crosses the target path,
a solid line will appear, instead of arrows, indicating
the target path and its orientation to the receiver.

Before marking target path, always use directional peak or special peak mode to verify
location.

Special Peak

MODE + (Spl Pk) [SK Toggle]

Special Peak Mode turns on only the peak antenna closest to the ground. Special Peak
Mode is used in applications such as very deep cable, or when the signal is too weak for
normal or directional peak tracing.

Inductive Peak (IndPk)

MODE + IndPk [SK Toggle]

™

If you cannot make a direct connection, or use the 3M
to apply a locating signal on the target, use the induction method. This method uses the
internal coil of the transmitter to generate a magnetic field.

The induction mode of the receiver is a mode in which the upper antenna of the receiver
is tuned to minimize distortion from the magnetic field of the transmitter.

78-8130-6151-8-E 19

Dynatel™ Dyna-Coupler clamp

Expanded Mode

When the third ring of the speaker icon is dotted or broken and ‘xpnd’ appears below the
speaker icon, the receiver is in “Expanded” mode. This mode is used for pinpointing a
target cable or pipe. The area of response of the receiver narrows, allowing the locator to
detect very small signal changes.

Depth and Current Estimate

Verifying the target path, depth and current can be helpful tools.

1. Pinpoint the cable or pipe being located.

2. Lower the tip of the receiver to the ground and
press Depth [SK].

− The depth to the target cable or pipe is
displayed in the units specified in the
receiver set up menu. The bold current
reading is a relative current measurement.
This reading can be compared to the current
reading that alternately flashes with the
frequency on the transmitter. The milliamp
reading is an actual current measurement.

− There are two options for measuring depth.
Live depth is a continuous measurement.
1-Shot Depth is an averaging of the depth
reading. When in 1-Shot mode, the unit will
average the depth reading for three seconds,
and then display the result on the screen.
Press Depth [SK] to alternate between the
two modes.

− Five depth readings can be saved with the
time, date and relative current measurements.

3. Pressing Save [SK] will place each entry in sequential order in memory (M1 - M5)
until five readings have been stored. The unit will overwrite saved entries in excess
of five, beginning with M1.

20 78-8130-6151-8-E

4. Press Clear All [SK] to delete all stored depth
information.

− The operator may select the memory location
to store the depth readings by pressing Mem
Select [SK]. When the preferred location
appears on the screen, press Save [SK]. The
screen and memory location will populate
with the current information.

− Each memory location can be reviewed by
pressing Mem Select [SK].

5. Press Locate [5] to return to Locate Mode.

Power frequencies refer to 50 or 60 Hz signals, and their harmonics that can be traced
without the use of a transmitter.

50: Best for general locating of passive power.

50H (high harmonic): If the 50 choice appears to be responding slowly, or poorly, then

50H is the second choice for locating of passive power.

50L (low harmonic): Third choice for passive power locating. May be used when 50 or
50L is weak or erratic.

100 Hz: Used for locating rectified AC power signals, often found on pipelines using
impressed current cathodic protection.

method and the directional peak (DirPk) mode. Other methods of connection and tracing
features are explained in previous sections.

1. Insert the ground rod into the ground, perpendicular to the suspected target path.

22 78-8130-6151-8-E

2. Remove the grounding from the near-end of the target cable/pipe.

Note: Never connect, or disconnect the transmitter when the unit is on.

3. Connect the red lead of the transmitter to the shield, neutral, or deenergized target
conductor.

4. Connect the black lead of the transmitter to the ground rod.

5. Perform a battery check by pressing and holding OFF [T-1].

6. Turn the power on the transmitter by pressing OHMS [T-2].

a. A solid tone from the transmitter indicates a complete circuit with a good

ground.

b. A beeping tone from the transmitter indicates a usable ground. An attempt

should be made to improve the ground.

c. No tone from the transmitter indicates a poor, or no ground. The transmitter will

display ‘OL’ in this instance. An attempt should be made to improve the ground.
Verify that the far end is grounded.

7. Press TRACE [T-3] to set the transmitter to Trace mode.

8. Select a frequency on the transmitter by pressing TRACE [T-3]. The unit will cycle
through the available frequencies (577, 8K, 33K, 133K, and ALL).

9. Press Power [1] to turn on the receiver.

10. Press Locate [5].

11. Press Cable/Pipe [SK].

12. Set the Frequency and mode of the receiver.

a. Press Freq [SK]

b. Select the same frequency on the receiver

as the transmitter by pressing Active [SK
Toggle].

c. Press Locate [5] to save the setting and

return to locate mode.

d. Press Mode [SK Toggle] until DirPk is

displayed.

13. Stand away from the suspected target path and adjust the Gain Down [4] until the
bar graph opens completely.

14. Walk in a wide circle with your back toward the transmitter (about 3 to 4.5 meters
away).

− Watch the receiver screen and listen to the signal. Take note of where the
receiver detects the strongest signals.

− The bar graph will close when the unit detects a signal, and the arrows
will reverse.

78-8130-6151-8-E 23

− Adjust the Gain Down [4] if the bar graph closes completely.

− The numbers on the display will change with the signal strength (smaller, as you
walk away from the target path; larger, as you approach the target path).

− Make a complete circle around the transmitter. Return to each point in the circle
that the receiver detected.

15. Measure the depth and current of each to identify the target path. The depth of the
target path should be as expected and the relative current should compare to the
relative current of the transmitter.

Note: The current reading will decrease steadily as the locator moves away from the
transmitter. When using higher frequencies, this decline is more evident.

16. Adjust the gain so that the bar graph responds to the target path (open when off
path, almost completely closed when directly over target).

17. Trace the cable/pipe at a slow walk while moving the receiver in a side-to-side
motion, keeping the receiver perpendicular to the ground.

18. Measure the depth and current occasionally to verify target path.

Note: In order to measure the depth and current accurately, the operator must
pinpoint the target pipe or cable, and the receiver handle should be in-line with the
target path.

− While in DirPk mode, find the highest signal strength [10].

− Lower the tip of the receiver to the ground. Twist the receiver left and right
while watching the signal strength.

− When the highest reading is displayed, the handle of the unit is in line with the
target pipe or cable.

Occasionally, signal will appear on adjacent cables or pipes. Compare the relative
and actual current readings over each path to help determine the target path. Current
readings will be significantly less on the adjacent cable compared to the target path.

19. As tracing proceeds, remember that the most powerful signal is near the transmitter.
As the receiver gets farther away from the transmitter the signal strength [10]
decreases. It may be necessary to readjust the gain as needed; to be sure there is
adequate signal for the receiver to operate. Press the Gain up/down [4] when the
bar graph is no longer visible (too little signal) or when the bar graph is closed (too
much signal).

20. Trace the path until you reach a logical termination point (i.e.: terminal, meter,
cabinet, etc).

Transmitter Signal

8. When the bar graph fills toward the left (red-and-white-striped) side of the screen,
the fault has been passed and is now behind the operator. Move back, inserting the
frame every few inches, until the arrows alternate back to green. Mark the point
beneath the center of the frame. Turn the earth frame 90 degrees and insert into the
ground over the previously marked point. Move the earth frame to the left and right
(following the directions of the green and red arrows). When the arrows reverse a
third time, turn the frame 90 degrees again. Pinpoint the fault by moving the frame
in the direction of the green and red arrows. The fault is located beneath the center
of the frame when the arrows change from one side to the other this time.

Figure 2

9. To verify the fault location, insert the frame’s red-and-white-striped probe directly
on the spot identified above. Pivot the frame in a circle around the red-and-white­striped leg re-inserting the green-banded leg in the ground every few degrees of the
circle (Figure 2). The arrow should always point toward the left (red) indicating that
the fault is directly below the red-and-white-striped leg.

10. After a fault is found and pinpointed, move the earth contact frame about one frame
width away from the fault and insert it in the ground with the green-banded leg
towards the fault. Compare the numeric signal level with the fault level reference
indicated in the lower left box labeled REF. If the reading is within 12 dB of the
reference, the operator has found the major fault. If the fault reading does not fall
within 12 db of the reference reading, multiple faults may exist. The signal level
of this secondary fault can be saved by pressing Fault 1 [SK] or Fault 2 [SK]. The
fault with the highest reading will be the primary fault.

(Capture Mode / Mode 1)

Menu [SK] + Setup [SK] + More>> [SK] + More>> [SK] + Com [SK Toggle] + NMEA

If the GPS unit is not configured properly, there is an error communicating with the
receiver, or the GPS has not acquired enough satellites to pinpoint the location, the
receiver will display the message “Insert External Device”.

When the receiver is communicating with a GPS
unit, the LAT and LONG coordinates received from
the unit will appear on the marker locate screen.

1. Locate a marker (See Locating Single Marker.)

2. Press Read [SK]

The information from the iD marker will display on the receiver screen, as well as the
GPS coordinates. This information is saved automatically in the Read Marker History.
(See Reviewing Read History.)

If the marker is a passive marker (rather than iD) the receiver will display “No iD
Marker Found”. The GPS coordinates of the attempt to read the non-iD marker are
stored in the Read Marker History as serial number # 0000-0000-0000. The marker
details will indicate “not an iD marker”, but will display the GPS coordinates.

Sending iD Data to GPS
(Capture-Transmit Mode / Mode 2)

Menu [SK] + Setup [SK] + More>> [SK] + More>> [SK] + Com [SK Toggle] + GIS

Receivers that have marker locating capability (indicated by ‘iD’ in the model number)
can be configured to send 3M

™

EMS iD Marker data directly to some GPS devices.
When a marker is located and read, the information read from the iD marker with feature
and attribute data is sent to the GPS device and is stamped with latitude, longitude and
date/time data. The data acquired during this logging process can be uploaded to GIS
mapping software. For more information and detailed instructions pertaining to specific
GPS units, refer to www.3M.com/dynatel GPS instruction sheet.

Path Mapping with GPS

The M-Series cable and pipe locators are compatible with hand-held GPS devices and
now have the ability to map the path of under ground target facilities. While measuring
the depth to the target, the technician can automatically log the coordinates of the
path on the GPS device. These logged points contain the Trace template that can have
valuable information regarding the facility (owner, utility, size, etc.) and the method used
to find the path (frequency, current, and measured depth).

In order to transmit the path information to a GPS device, the GPS has to have the
ability to accept information on one of its com ports at 4800 Baud. Using the manual
supplied with the GPS device, configure the com port of the GPS to communicate with
the receiver.

Create Trace Templates

The easiest way to create a Trace template is using the Dynatel PC Tools software.
(Software available for no charge at www.3M.com/dynatel - 3M™ Dynatel™ M-Series
Locator PC Tools).

1. Create a TRACE template.

2. Save and download the template to the receiver.

Up to four Trace Templates can be stored on the Receiver.

Each Trace template is limited to 132 user editable characters.

The trace template appears in table format: two columns with six lines.

The first column is limited to 8 characters and the second column is limited to 14
characters. In addition to the 132 character table, the receiver will send a sequence
number, the frequency, the measured depth of the conductor, and the current to the GPS.

Select Com Port Setting

Menu[6] + Com [SK] + GIS [SK] (or PDA [SK])

If the GPS has the ability to send NMEA coordinates on its com port and has the ability
to receive information at 4800 baud, set the receiver’s com port to GIS.

If the GPS only has the ability to receive information, set the com port of the receiver to
PDA mode.

Log Prompt = On: Before the receiver returns to locate mode, a verification screen will
pop up on the receiver with the trace template information that will be sent to the GPS
device. This information can be modified and confirmed. Press OK to send to GPS.

Log Prompt = Off: When the receiver returns to locate mode, the trace template and
locate information will be sent automatically to the GPS.

Sending Path Information to GPS Device

1. Establish communication on GPS unit.

2. Set com port on receiver.

3. Locate target utility.

4. Measure depth to target utility.

− If Log prompt is activated, when the Locate button is pressed (or after a five
second delay) a screen will appear that displays the path information.

5. Press OK to send the information to the GPS, or Exit to abort the exchange.
