If this equipment is used in a manner not specified by 3M, the protections provided by the equipment may be impaired.

Explanation of Signal Word Consequences

m Warning: Indicates hazardous situation which if not avoided, could result in death or serious injury.

m Caution: Indicates hazardous situation which if not avoided, could result in minor or moderate injury.

Explanation of Product Safety Label Symbols

Do not throw away in normal trash.

c Warning: Risk of electric shock

m WARNING

This WARNING applies to the following 3M Dyna-Couplers;• 3" (75 mm) - Part number 3001• 4.5" (114 mm) - Part number 4001• 6" (150 mm) - Part number 1196• All accessory kits containing any of the listed Dyna-Couplers - Part numbers 3019, 4519,

1196/CA potential for electrical shock exists when using the Dyna-Coupler on cables energized with electrical power. Use appropriate safety procedures.DO NOT USE ON CABLES CARRYING IN EXCESS OF 600 VOLTS RMS.

6 78-9000-0193-0-B

m WARNING

This WARNING applies to the use of the Direct Connect Cables and the Transmitter.To avoid potential shock, or electrically damaging the Transmitter, when setting up the Transmitter to locate using the Direct Connect method, follow these basic steps;• ALWAYS plug the Direct Connect Cable into the Transmitter Output Jack [T-6] BEFORE

connecting the leads to the cable/pipe to be located and the ground rod. – Connect the red lead to the cable/pipe. – Connect the black lead to ground rod.A POTENTIAL FOR ELECTRICAL SHOCK, AND/OR TRANSMITTER ELECTRICAL DAMAGE, EXISTS WHEN USING THE DIRECT CONNECT CABLE ON CABLES ENERGIZED WITH ELECTRICAL POWER IF THE ABOVE INSTRUCTIONS ARE NOT FOLLOWED. USE APPROPRIATE SAFETY PROCEDURES.CHECK VOLTAGE BEFORE CONNECTING TRANSMITTER. VOLTAGE HIGHER THAN 240 VOLTS WILL DAMAGE EQUIPMENT. FOLLOW STANDARD PROCEDURES FOR REDUCING THE VOLTAGE.

6. Locating Buried Cables And PipesA. Transmitter ConnectionsPerformabatterytest.Useoneofthefollowingthreemethodstoproduceatracesignalonthetargetpipeorcable.

1. Direct Connect Method

m WARNING

This WARNING applies to the use of the Direct Connect Cables and the Transmitter.To avoid potential shock, or electrically damaging the Transmitter, when setting up the Transmitter to locate using the Direct Connect method, follow these basic steps;• ALWAYS plug the Direct Connect Cable into the Transmitter Output Jack [T-6] BEFORE

connecting the leads to the cable/pipe to be located and the ground rod. – Connect the red lead to the cable/pipe. – Connect the black lead to ground rod.A POTENTIAL FOR ELECTRICAL SHOCK, AND/OR TRANSMITTER ELECTRICAL DAMAGE, EXISTS WHEN USING THE DIRECT CONNECT CABLE ON CABLES ENERGIZED WITH ELECTRICAL POWER IF THE ABOVE INSTRUCTIONS ARE NOT FOLLOWED. USE APPROPRIATE SAFETY PROCEDURES.CHECK VOLTAGE BEFORE CONNECTING TRANSMITTER. VOLTAGE HIGHER THAN 240 VOLTS WILL DAMAGE EQUIPMENT. FOLLOW STANDARD PROCEDURES FOR REDUCING THE VOLTAGE.

• PlugthedirectconnectcableintotheOutput Jack[T-6]ofthetransmitter.Connecttheblackcliptothegroundrod.Placethegroundrodintheearthperpendiculartothesuspectedcable/pipepath.Ifnecessary,extendtheblackleadwiththeGroundExtensionCable(#9043availableseparately).

• Removethegroundbondingandattachtheredcliptotheshieldofthecable,pipe,ortargetconductor.(Iflocatingpowercables,theredclipcanbeattachedtothetransformercabinet,orthemeterbox).Metalcontactmustbemadebetweentheredclipandthetransformercabinetormeterbox.Ifpainted,somepaintwillneedtoberemoved/scrapedofftoallowmetal-to-metalcontact.

• TurnthetransmitteronbypressingOhms[T-2].Thecontinuityofthecircuitwillbemeasured.TheresultsaredisplayedontheDigital Display[T-4]inohmsandasanaudibletone.

Note: In the ohms mode, the transmitter can detect voltage as well as ohms. If a low voltage is detected, the Digital Display [T-4] 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 Digital Display [T-4]. If a high AC voltage is detected, a rapid beeping tone will be heard.

• PressTrace [T-3]repeatedlyuntilthedesiredfrequencyappearsonthedisplay.Notethatthenumberthatflashesalternatelywiththeselectedfrequencyiscalledtherelativecurrent.Thisnumbercanbeusefulinidentifyingthetargetcable/pipeandisdiscussedmorein8.DepthandCurrentEstimateand10.LocatinginDirectionalPeakMode.

2. Dyna-Coupler Method

m WARNING

This WARNING applies to the following 3M Dyna-Couplers;• 3" (75 mm) - Part number 3001• 4.5" (114 mm) - Part number 4001• 6" (150 mm) - Part number 1196• All accessory kits containing any of the listed Dyna-Couplers - Part numbers 3019, 4519,

1196/CA potential for electrical shock exists when using the Dyna-Coupler on cables energized with electrical power. Use appropriate safety procedures.DO NOT USE ON CABLES CARRYING IN EXCESS OF 600 VOLTS RMS.

• ConnecttheDyna-CouplertothetransmitterOutput Jack[T-6]usingthecouplercable(9011).

• ClamptheDyna-Coupleraroundthecableorpipe,belowanybonds,justbeforeitenterstheearth.The jaws of the coupler must fully close.

• PressTrace [T-3]toturnonthetransmitter.Pressagaintoselect8kHz,33kHz,82kHzor133kHz.

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

Use a ground extension cable, or wire, and ground rod set-up between a target pipe/cable and a gas meter valve/box, or cable/electrical meter box. This will isolate the locate signal to the target pipe/cable section below the meter/box, between the ground-ing points. This provides a good return path for the tracing signal. Insulating coupling above a gas meter valve on a pipe will isolate the returning signal from ground and may make locating more difficult.

A. Non-Sweeping Induction Mode Locating

• Positionthetransmitteroverthetargetfacility,withthehingeofthetransmitteroverandinlinewiththecable/pipepath.RemoveanycablesfromtheOutput Jack [T-6].

− AligntheInductionDirectionarrowsonthetransmitterwiththetargetconductor.

• Turnonthetransmitter,selectthefrequencyandselecthighoutputormaximumoutputpowerlevelforbestsignal-to-noiseratio.

• TracethesignalpathwiththereceiverusingtheInductionPeak(IndPk)mode.

78-9000-0193-0-B 25

Note: If nothing is plugged into the Output Jack [T-6] of the transmitter, the transmitter will automatically turn on the internal antennae, and the last frequency used (8 kHz, 33 kHz, 82 kHz or 133 kHz) will broadcast in induction mode.

The induction frequency can be changed by pressing the Trace [T-3] (Frequency [T-3] on 2550E) button on the transmitter. For best results, the receiver should be at least 7.6 m (25 feet) away from the transmitter to begin tracing the target path, have the gain set between 78-84% and have the receiver in Induction Peak (Ind Pk) mode when starting the sweep. Attempting to trace the target close to the transmitter may lead to false indications due to the receiver detecting the large magnetic field radiating from the transmitter.

Note: Two active line locating frequencies, 577 Hz and 33 kHz, are simultaneously transmitted with the fault finding signal. This allows convenient switching back and forth between fault finding mode and cable/pipe locate mode on the receiver during fault finding without returning to the transmitter. The transmitter Digital Display [T-4] will flash between 577 Hz and 33 kHz. It does not display the fault finding frequencies.

To reduce the risks associated with environmental contamination and possible injury:The 12W transmitter utilizes the 2200RB rechargeable battery for the Maximum Output power level. This is a maintenance-free sealed lead (Pb)-acid battery.• Replace the battery if the acid solution leaks.• The batteries are not serviceable.• Do not disassemble batteries.• Do not remove vent caps.• Do not rest tools or cables on batteries.• Store lead-acid batteries with adequate ventilation.• Do not heat batteries above 60°C (140°F)• Never recharge batteries in an unventilated, enclosed space.• Spent batteries must be treated as hazardous waste. Dispose of batteries and electronic

components in accordance with all regulations.• Do not incinerate batteries.• Always remove/disconnect batteries when not in use or storing for long periods of time.
