INTRODUCTION The 3M ™ Dynatel ™ 2273 Adv anced Cable and Fault Locator consists of a T ransmitter and a Receiv er for locating buried cables or Activ e Duct Probes (sondes). It also measures and pinpoints sheath faults in bur ied cables and conductor faults in aerial cables.
INITIAL RECEIVER CONFIGURA TION Display depth units (inches, feet and inches, or centimeters) may be changed while holding and pressing . For each press, one of three units will display . T o change the passive Po wer frequency , press and hold then press to toggle between 50 or 60 Hz as displayed in the lo w er left corner of the display .
TRANSMITTER BA TTER Y TEST T o test the Ba tteries, press and hold . Listen to the tone and w atch the display . • solid tone and 'OK' indicates batteries good; • beeping tone and 'LO' indicates batteries low; • no tone and '- -' indicates replace batteries.
LOCA TING A BURIED CABLE T ransmitter Setup Note: K ey descriptions can be found inside the T ransmitter lid. Perform a battery test and then connect the T r ansmitter using one of the three methods below to put tr acing signal on a cable . DANGER! V oltage greater than 240 volts will damage equipment and cause personal injury and death.
Make sure the T ransmitter is off. Plug the direct connect cable into the front panel jack. Connect the Black clip to the ground rod. Place the ground rod in the earth perpendicular to the suspected cable path. If necessary , extend the black lead with the Ground Extension Cable.
Press to select Trace mode. Press ag ain to select one or all of the four frequencies. The display will alternate between displaying the selected frequency and the output signal current. It is best to choose the low est frequency for direct connect with far-end g round and a high frequency for direct connect with no far -end ground.
Dyna-Coupler Method Cable Path Connect the Dyna-Coupler to the T ransmitter front panel jac k using the coupler cable. Clamp the Dyna-Coupler around the cable belo w any bonds just before the cable enters the earth. The jaws of the coupler m ust fully close.
Induction Method Place the transmitter on the ground ov er the target cable with the lid hinge in line with the cable path. Press to turn the T ransmitter on. Press again to select either 33 kHz or 200 kHz. For gr eater tracing range, select high output le vel by pressing .
LOCA TING A BURIED CABLE Receiver Setup Note: K ey descr iptions can be found on the side of the Recei ver . Press to turn the Receiver on. Press to select the 50/60 Hz po w er frequenc y (see section on Selecting P assive P ow er F requencies on Page 12 ) for passiv e locating; otherwise, select the same frequency as the T ransmitter .
About T race Modes P eak: In this mode, as the antenna crosses the cable, the Receiv er speaker volume increases to a maximum and the bar graph fills from both sides toward the middle. As the antenna moves off the cable path, the speaker volume decreases and the bar graph opens.
Selecting P assive P ower Frequencies See section Initial Receiver Conf iguration (P a ge 3) to set the power frequenc y to 50 Hz or 60 Hz. The Receiv er can be tuned to locate 3 dif ferent harmonics of the chosen power frequenc y . H50 Hz or H60 Hz (high harmonic): Best for general locating of passi ve po wer .
DETERMINING CABLE DEPTH AND CURRENT Place the Recei ver Antenna on the ground directly above the cable with the handle parallel to the path. Press and the display will indicate the cable depth and relati ve current . Current is displayed in the lower left corner of the display .
Using Current Indications During Locating Both the Transmitter and Recei ver will indicate cable current. These current indications will help to select a trace frequency , identify the cor rect cable and troubleshoot the set up. When using the direct connect method, the Transmitter output current n umber is displayed.
LOCA TING SHEA TH F A UL TS T ransmitter Setup Remove both the near -end and far-end shield bonds from the test section. Perform a battery test then with the T ransmitter off, connect the Black clip to the ground rod. Place the ground rod behind the T ransmitter, away from the faulted section, and in line with the cable path.
Page 16 T o verify the fault loca tion, insert the frame's red probe directly on the spot identified above . Pivot the frame in a circle around the red leg r e- inserting the green leg in the ground e very few degr ees of the cir cle. T he bar graph should always be on the left (red) indicating that the f ault is directly below the red leg.
Page 17 LOCA TING AN A CTIVE DUCT PROBE (ADP) Press to turn the Recei ver on. Press to select the 33kHz frequency . Press to select the Peak mode . If you find that the recei ved signal is too weak in this mode, try the Special Peak mode.
Page 18 LOCA TING EMS MARKERS EMS markers may be detected and located using either the Dynatel ™ 2205 or 2206 EMS Marker Locating Accessory . T o attach the accessory , slide the Recei ver horizontally into EMS Marker Locating Accessory mounting slot.
Page 19 TONING AERIAL FA UL TS T ransmitter Setup Perform a battery test; then with the T ransmitter off, plug the direct connect cable into the front panel jack.
Page 20 CABLE OR PAIR IDENTIFICA TION T ransmitter Setup T ransmitter setup is the same to identify cables or pairs. Howe ver , Receiver setups are dif ferent. Perform a battery test; then with the transmitter of f, connect the Dyna- Coupler to the T ransmitter front panel jack using the coupler cable.
