Radiodetection C.A.T, Genny User Manual

User guide

for C.A.T and Genny
and C.A.T+ and Genny+

The C.A.T and Genny combine to make
the perfect general purpose tools for cable
avoidance. Their rugged construction
ensures long life and reliability whilst the
simple controls promote effective use with
minimal training.

For those who require pinpoint accuracy
and depth information, the C.A.T+ and
Genny+ add visual indication of signal
strength together with a buried utility depth
measurement capability.

Genny+ Transmitter features

The only differences between the Genny and Genny+
are that the signal radiating from the Genny+ and the
tone from its speaker are continuous rather than
pulsed. Operationally they are similar.

Operation of Power and Radio modes

Regularly check your C.A.T and Genny, in all
modes, over a cable which gives a response you
are familiar with.

Power mode

For detection of ‘power’ signals radiated by loaded
cables. These are often found ‘re-radiated’ by other,
nearby conductors. Select Power using the Function
switch. Press and hold the On/Off switch. Replace
batteries if no initial ‘bleep’ is heard to confirm good
battery condition.

Rotate the Sensitivity
Control fully clockwise
for maximum
sensitivity but reduce
if there is a blanket
signal across the site.

Define the area to be
excavated and carry
out a grid pattern
sweep.

Sweep holding the C.A.T upright and at your side.
Contunue the sweep beyond the perimeter of the area
to be excavated.

The presence of a buried conducting pipe or cable will
be indicated by a tone emitted from the loudspeaker.

Keep the blade of the C.A.T vertical and move slowly
backwards and forwards over the conductor, reducing
the sensitivity for a narrower response. With the
C.A.T+ use the meter deflection to aid pinpointing.
Maximum meter deflection
will indicate the position of
the conductor.

When directly over the
conductor and with the
sensitivity level set for a
narrow response, rotate
the C.A.T on its axis until
the signal minimum is
found. The blade is now in
line with the conductor.

Trace the conductor out of
the area, marking the
position as required with chalk or paint.

Radio mode

For detection of radio signals originating from distant
radio transmitters. These penetrate the ground and are
re-radiated by buried conductors. However, they are
not always present.

After completion of Power mode sweep, repeat the
procedure with Radio mode selected.

WARNING
The C.A.T will detect almost all buried conductors

but there are some which do not radiate any signal
which the C.A.T will not detect.

There are also some live power cables which the
C.A.T is not able to detect in the Power mode.

The C.A.T does not indicate whether a signal is
from a single cable or from several in close
proximity.

Note

The C.A.T+ will not provide depth information in either
the Power or Radio modes.

Locating with the C.A.T and Genny

The Genny is used to apply a tone to a buried
conductor. This signal can be traced using the C.A.T
locator switched to the Genny mode.

Direct Connection

Direct Connection is the most effective form of signal
application and is suitable for connection to a valve,
meter, junction box or other access point.

WARNING
Connection to a power cable sheath should only

be undertaken by qualified personnel.

Method

Plug the Connection lead into the Genny connection
socket and attach the red lead to the target line. If
necessary clean the connection point to ensure a good
electrical contact.

Clip the ground lead to the earth stake which should
be placed in the ground 3 to 4 paces away from, and
at right angles to the target line.

Alternatively the ground lead may be clipped to the rim
of a valve box or manhole cover. Use the spool lead to
extend the earth connection if necessary.

Switch the Genny on. Agood connection is indicated
by a drop in loudspeaker tone. If there is no tone or it
is a very slow bleep, replace the batteries.

Switch the C.A.T to Genny mode and begin to trace
the line from the point of application. Pinpoint using the
same method as described for Power and Radio
modes.

Induction

Induction is a convenient and quick way of applying the
Genny signal to a pipe or cable where limited access
does not permit direct connection or use of the Signal
Clamp.

Place the
Genny over the
assumed
position of the
conductor in the
orientation
shown.

Start tracing the cable or pipe at least five paces from
the Genny with the C.A.T in Genny mode. Working too
close to the Genny may give false readings as the
C.A.T will detect more signal directly from the Genny
than from the conductor.

If using the C.A.T+ do not attempt to take depth
readings unless the distance between the C.A.T+ and
Genny+ is greater than 30 paces (see ‘Taking depth
readings using the C.A.T+’).

Active search
using
Induction

Placing the
Genny on its
side swamps
an area with
Genny signal.

Alternatively,
use a two
man
technique to
search an
area for
buried utilities.

Using the optional Signal Clamp

The Signal Clamp applies a Genny signal safely to a
pipe or live cable of up to 76mm (3 inches) diameter,
without interrupting the supply.

Method

Plug the Clamp into the Genny Connection socket.
Place the Clamp around the pipe or cable ensuring the

jaws are closed. Switch the Genny on. Open and close
the Clamp. If the jaws are closing correctly a drop in
speaker tone will be heard.

An earth
connection is not
necessary but
efficient signal
transfer is only
achieved if the
target conductor is
grounded at both
ends. This is
usually the case
with power cables.

The Signal Clamp can be used with either Genny or
Genny+

Using the optional Live Plug Connector

The Live Plug Connector applies the Genny signal to a
live domestic power socket and, via the domestic
wiring system, to the service cable and supply cable in
the street.

Method

Connect the Live
Plug Connector to
the Genny socket
and the power
socket.

Switch on the
power socket and
the Genny.

Note

The Live Plug
Connector provides
protection to 250Vac.

Using the optional Mouse Signal Transmitter

The Mouse is a small self-contained watertight
transmittter which can be detected by the C.A.T when
switched to the Genny mode.

Method

Replace the battery in the Mouse. Attach the Mouse to
a drain rod using an appropriate connector (purchased
separately).

Place the Mouse on the ground, set the C.A.T to
Genny mode and, whilst holding the C.A.T in line with
the Mouse, check that a signal is being received.

Insert the Mouse approximately 1m/yd into the
duct/drain and adjust the C.A.T sensitivity to receive
the signal.

A ghost signal appears before and behind the main
signal position. Reduce the C.A.T sensitivity to receive
only the main signal.

by Induction method.

Hold the C.A.T still,
vertical and at right angles to the buried line. Momentarily
depress the depth button. The display will show a moving
clockface followed by the depth measurement.

Taking Mouse depth measurements using the C.A.T+

Depth measurement is only possible when using the
C.A.T+ in the Genny mode with a Mouse+ transmitter,
identified with a central orange band.

The approximate depth to the Mouse will then be
displayed on the meter.

Do not use the C.A.T+ depth measurement to decide

if mechanical digging over buried conductor is
appropriate.
