INTRODUCTION

The AT-3500 underground cable/pipe locator system is designed for the uncomplicated and user-friendly determination of the

location, orientation and depth of metallic lines (e.g. cable and pipe lines).

It can be used to probe areas for unknown lines or for locating speciﬁc lines.

The AT-3500 is distinguished by the following features:

Robust construction for use in poor weather and in harsh environments

Simple, user-friendly operation concept with a minimum number of controls

Reliable battery status indicator

OPERATION

Decide which mode of operation to use for your application1.

Induction:UÊ Transmitter’s signal is emitted through the integrated antenna and is thereby inductively coupled with

any metallic lines located within a certain radius.

Place the T-3500 transmitter on the site to be searched. Refer to Figs.1, 2.3&4.i.

Direct Connection:UÊ Transmitter’s signal is directly coupled with a metallic line via the measurement cable which is

connected to the jacks on the front panel of the transmitter. Transmitter clamps, alligator clips or power socket adapters

(for example) may be used to connect the measurement cable to the lines.

Connect the T-3500 transmitter to the line to be located using the desired method. Refer to Figs 1, 2, 3, & 4i.

APPLICATIONS AND PRINCIPLES OF DIRECT COUPLING

Single-wire cables or pipes (with or without insulation against ground)1.

The distance between the grounding rod and the ends of the connected lines should be as great as possible because return

current tends to ﬂow through the earth into adjacent lines, which could result in their path being followed.

Single-wire cable with metallic screen and ground insulation2.

Short circuit between internal conductor and screen at the end of the cable with ground at the beginning and end of the

cable as well.

Failure to make the connection as shown will result in current cancellation from the internal conductor and the return current

in the screen. Under certain circumstances this can prevent the cable from being detected.

Multiple-wire cable (internal conductor connected or disconnected) with metallic screen and grounding insulation3.

Same application as in example 1

Metallic conduit (with or without insulation) 4.

the grounding rod and the conduit should be spaced as far apart as possible. Under certain circumstances, optimum

positioning of the grounding rod may require several attempts.

If a return wire is available5.

the spacing of the return wire should correspond to at least 10 times the depth of the line being located.

Pair of wires (with or without screen) with short circuit at the end of the cable6.

For twisted cable pair (with a length of lay of the twist greater or equal to the laying depth), the orientation of the cable can

be easily determined.

Adjacent lines which are horizontal to each other ¨ Minimum of the reception signal

Lines situated on top of each other vertically ¨ Maximum of the reception signal

Direct Coupling (Refer to Fig. 2.)

Connect the red test lead of the T-3500 transmitter with the conductor to be traced1.

Connect the black test lead of the T-3500 transmitter to ground using the grounding rod. Alternatively the black test lead 2.

may be clipped to the rim of a valve box or manhole cover.

Switch the T-3500 on3.

Select pulse or continuous signal transmission4.

Switch the R-3500 Receiver on5.

Begin to trace the cable from the point of application about 50-FT (15m) away6.

Move slowly over the cable. Decrease or increase the sensitivity as needed7.

Direct Coupling using the A-3500 Clamp (Refer to Fig. 3.)

Plug the SC-3500 clamp into the T-3500 transmitter connection socket1.

Place the clamp around the pipe or cable2.

Switch the T-3500 transmitter on3.

Set the T-3500 transmitter to pulse or continuous signal transmission4.

Switch the R-3500 Receiver on5.

Select transmitter 6.

Begin to trace the cable from the point of application about 15m away7.

Inductive Coupling (Refer to Fig. 4.)

Position the T-3500 transmitter above the presumed cable1.

Switch on the T-3500 transmitter2.

Switch on the R-3500 receiver3.

Select the appropriate mode. Refer to section: Operation:R-35004.

Begin to trace the line from the transmitter at least 15m away.5.

Make sure that a distance of at least 50-FT (15m) is always maintained between the receiver and transmitter in order to 6.

prevent the coupling of the transmitter’s signal through the air.

Locating Passive Lines (Radio and Power Modes) (Refer to Fig. 5.)

The R-3500 Receiver can locate passive cables that carry radio signals in the frequency range between 15 kHz and 23 kHz as well

as power signals between the range of 50 Hz and 60 Hz without the help of the T-3500 Transmitter.

Turn the R-3500 Receiver on1.

Select radio mode or power mode. Refer to section 8 OPERATION.2.

Set the sensitivity to maximum3.

Sweep the area using a grid pattern as shown below4.

Adjust the sensitivity to pinpoint the conductor5.

Rotate the R-3500 to ﬁnd the maximum response6.

Locating unknown cables (Refer to Fig. 6.)

Use the T-3500 Transmitter using the inductive mode. 1.

Use the R-3500 Receiver to sweep the area. Keep the receiver 50-FT (15m) apart from the transmitter.2.

Select the desired mode of operation. 3.

Adjust the sensitivity of the R-3500 as needed4.

When a conductor is located, pinpoint the strongest signal and mark the location5.

Repeat steps 1 and 2. Move the transmitter at least 3.3-FT (1m) and 90-degree from the initial position.6.

Repeat the process until the right cable is detected. 7.

Depth Measurement (Refer to Fig. 7.)

Connect the T-3500 transmitter with the cable or the metallic pipe1.

Turn the T-3500 transmitter on. Use continuous signal mode for better result2.

Turn the R-3500 receiver on and move at least 50-FT (15m) away from the transmitter3.

Rotate the R-3500 receiver until the maximum signal strength is detected4.

Push control15. to take an automatic depth measurement

The measurement will display as follow:6.

To change the unit of measure, refer to R-3500 mode of operation (section 8).7.

For non-metallic pipe, use the M-3000 mouse. Refer to R-3500 receiver mode of operation section 9 to set the receiver 8.

accordingly.

For Power and Radio signals, an estimated depth measurement can be taken as follow:9.

Push control3 to select Power or Radio mode a.

Move to one side of the suspected cable until the following symbol appears: b.

Mark the spotc.

Move to the other side until the symbol appears againd.

Mark the spote.

Measure the distance between the two spotsf.

Divide the measurement by 2 to ﬁnd the depth of the cable.g.

ERROR MESSAGES DURING A DEPTH MEASUREMENT

Symbol Meaning

For of one of the following reasons, the depth could not be measured:

% The signal received was too weak or too irregular.

% The receiver was not held steady enough during the measuring process.

The receiver was not positioned directly above the line at the beginning of the process.

The depth of the metallic conductor amounts to more than 5 m (16 ft).

The depth of the metallic conductor amounts to less than 30 cm (1 ft). Such conductors must

be specially marked in order to prevent damage during construction.

The receiver was moved too far to the left or right while making a rough estimate. Move in

the opposite direction until the following symbol appears:

MAINTENANCE

Changing the battery in the R-3500 receiver

The status of the receiver’s batteries is checked upon start-up and indicated in the display.

The system regularly checks the battery strength as well. If battery capacity falls below 10 % of the threshold value, an audible

warning signal is given and the current status of the batteries is shown in the upper part of the display.

In order to replace the ten 1.5 V mignon (AA) batteries, the battery housing must be removed as described in the following

illustrations:

Changing the batteries in the T-3500 transmitter

The batteries in the transmitter have to be replaced as soon as the red LED battery indicator starts to blink.

Should this occur while the user is busy locating a line with the receiver, he/she will be informed of the weak batteries via the

reception signal:

Ty pe of signal Normal signal Signal when batteries are weak

In order to change the six 1.5 V mono (D cell) batteries, both screws on the back of the transmitter must be (e.g. with the aid of

a coin) turned through ¼ turn (1) and the battery tray must be pulled (2). Please note that all the batteries are ﬁtted in the same

direction.

Changing the ﬂoor cap on the R-3500 receiver

The plastic ﬂoor cap, which prevents the tip of the receiver from being damaged, can be easily replaced with the aid of a pointed

object (e.g. screw driver). Replacements can be ordered through the SEBA KMT sales team.
