Congratulations! You have just purchased one of the finest, most advanced locating devices available today!

™

The 3M

Dynatel™ Cable/Pipe/Fault Locators 2250M-iD/2273M-iD are designed with all of the functionality of previous Dynatel models, and iD versions have the enhanced capability to read and write user information into the 3M iD markers. Information such as a pre-programmed identification number, facility data, application type, placement date and other details can all be read, stored and downloaded to your PC for enhanced resource management with this revolutionary equipment. The Dynatel Cable/Pipe/Fault Locators 2250M-iD/2273M-iD will also search for two different types of utility markers simultaneously. When used in conjunction with a hand-held GPS device the ability to transmit path and marker coordinates multiplies the potential to the mapping industry. This equipment provides a simple system for mapping utility information directly into CAD and GIS systems.

The 2250M/2273M Series transmitters are available in 3-watt, 5-watt and 12-watt units. 12 watts for the 12-watt transmitter, or 5 watts for the 5-watt transmitter, is attained by utilizing the Cigarette Lighter Adapter or External Rechargeable Battery (2200RB).

3M is dedicated to bringing you premium equipment with outstanding reliability, backed by one of the best warranties in the business and outstanding service.

Visit our website at www.3M.com/dynatel for more application notes and product information.

1. Safety Information

Please read, understand and follow all safety information contained in these instructions prior to the use of the 3M™ Dynatel™ Cable/Pipe/Fault Advanced M-Series Locator. Retain these instructions for future reference.

A. Intended Use

The 3M Dynatel Cable/Pipe/Fault Advanced M-Series Locator is used to identify the placement of underground utility lines. The system must be installed as specified in the 3M Dynatel Cable/Pipe/Fault Advanced Locator 2250M/2273M Series Operator Manual. It has not been evaluated for other uses or locations. 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

! Warning:

! Caution:

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

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.

! 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/C

A 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 78-8130-6150-0 Rev G

Warning: Risk of electric shock

! 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.

2. About This Manual

There are two basic models included in the 3M™ Dynatel™ Locator 2200M Series. The 2250M locator is designed for cable/pipe locating. The 2273M locator is designed for cable/pipe and fault locating. The iD option (read/write capability to 3M is available for both models. There are three transmitter options: 3 Watt, 5 Watt, or 12 Watt. This instruction manual will include all features. All instructions are applicable to all products, unless noted.

The 12-watt transmitter option offers additional power output levels for improved induction performance and 8 kHz (low frequency) induction for shallow facilities, such as risers. Output Power up to 12 Watts for the 12-watt transmitter is achieved using the supplied external power source. The maximum output power in Direct Connect method is reduced to below FCC limits. (FCC limits: 1 Watt at 200 kHz and 10 Watts at 33 kHz)

In order to demonstrate all available functions, the illustrations depict the 2273M-iD receiver unit and the 2250 and 2273 12-watt transmitters. The 2250M receiver may vary from the illustrations shown.

! WARNING

To reduce the risk associated with hazardous voltage:

• Potential for electric shock exists when handling connection cables while the transmitter is

ON. Make all connections prior to powering on the unit. Turn transmitter OFF before handling connection cables.

• Voltage greater than 240 volts will damage equipment and could cause personal injury or

death. Make all connections before turning on the transmitter. Follow standard procedures

for reducing the voltage.

• Do not change or modify this product in any way.

H. Rechargeable Battery

The 3M™ Dynatel™ Sealed Gel-Cell Battery 2200RB can be used as an auxiliary battery in 3M™ Dynatel™ Transmitters 2200 Series. It plugs into the External Jack [T-7] and provides power for the transmitter. When the rechargeable battery is plugged in, normal output, high output, and maximum output are available. When the rechargeable battery is connected to the transmitter, the alkaline batteries are bypassed. The rechargeable battery is a lead acid battery rated at 5.4 amp-hours and is equipped with a user replaceable fuse (5A/32V).

Note: The internal batteries must be at least 5.4 volts. Do not remove the alkaline batteries from the transmitter when using the rechargeable battery. Rechargeable battery, or cigarette lighter adapter cable, is required for Maximum output level.

Rechargeable battery is shown installed in the well of the transmitter case.
