WARNING
Distraction/loss of attention
ing dynamic applications, for example stakeout procedures, there is a dan-
Dur
ger of accidents occurring if the user does not pay attention to the environmental conditions around, for example obstacles, excavations or traffic.
Precautions:
▶
The person responsible for the product must make all users fully aware of
the existing dangers.
WARNING
The absence of a positive indication does not guarantee the non-existence of a
tility.
u
Utilities without a detectable signal may be present.
The locators can only locate non-metallic utilities such as plastic pipes, typically
used by the water and gas utilities, with the use of appropriate accessories.
Precautions:
▶
Always excavate with care.
WARNING
Depth reading on locator might differ from actual depth of utility
When taking a dep
of a utility or to a sonde within the utility. Depending on the diameter of a utility, the depth reading might differ from the actual depth of the utility. This
specifically applies when the signal for depth estimation is produced by a
sonde lying in a large-diameter pipe or duct.
Precautions:

Do not clip a transmitter clamp around live utilities that have impaired or
no insulation.
Always ensure that the transmitter plug connector is connected to the
transmitter before you clip the transmitter clamp around a live utility.
DANGER
Never connect the cable set of the transmitter directly to a live electrical
utility.
DANGER

he signal transmitter can output potentially lethal voltages!
T
Precautions:
▶
Take care when using the maximum power output of the signal transmitter.
▶
Take care when handling exposed or non-insulated connections, including
the transmitter’s cable set, the earth pin and the connection to the utility.
▶
Notify others who may be working on or around the utility.
WARNING

2.1 System Information
General description
Locators are used to detect buried conductive utilities that emit an electromag-
tic signal. Such a signal is generated as an electrical current passes through
ne
the utility.
Signal transmitters are used to apply a distinct signal to utilities with the following intention:
•
o improve the detection success.
T
•
To trace the route of a utility.
•
To make a depth or current measurement.
Accessories are used with the locator and transmitter to localise the position
o
f utilities, including some that are non-metallic.
The locators and transmitters described within this manual greatly facilitate the
search process and help to reduce the dangers and costs associated with utility
strikes. However, electromagnetic location depends on the utilities being conductive (metallic) and emitting a signal as current passes through them.
☞
Keep in mind that a locator on its own cannot detect all utilities. Take
car
e when excavating. We recommend that you adopt a safe system
which includes the planning of the search process in advance, the use
of utility maps, the use of locators and transmitters, and the use of
safe digging practices.
