INSTRUCTION MANUAL
Advanced cable locator
C-LOGIC 3900
Code: 301000061
ENGLISH
This Cable Locator is a portable instrument consisting of a transmitter, a receiver and some
accessories. It is characterized by highly stable and reliable electrical performance. The
transmitter sends to the target cable (or metal pipes) an AC voltage modulated by digital
signals, which generates an alternating electric field; Put the sensor head of the receiver
close to this electric field, and the sensor will generate induced voltage. This instrument can
magnify this weak voltage signal by hundreds of times and then display it via an LCD screen,
so that the position of the buried cables or pipes, as well as their faults, can be detected
based on the change of the signal.
The transmitter not only transmits signals but also acts as an AC/DC voltmeter, so that the
instrument can display the voltage of the tested line, in addition to a warning symbol when
testing a live line.
This Cable Locator Is applicable for construction involving telecommunication cables, power
cables and building pipelines, as well as maintenance of such cables and pipelines.
SAFETY INFORMATION
This Cable Locator is produced in accordance with the safety specifications for electronic
meters and testing instruments and has been completely tested before packaging and
transport.
Before using this device, please read the manual carefully and follow all of the instructions.
Failure to stand by these instructions or ignoring the warnings and cautions herein may lead
to personal hurt, threat to life or damage of equipment.
Please observe the following instructions to ensure safe operation and optimal performance.
PREPARATION
• Before the first use, please check whether the cable locator can function normally and
ensure it is not damaged during storage and transport. If there is any damage, please
contact the supplier.
• Before using a locator that has been placed or transported under extreme climate
conditions, please place it under a new favorable environment for a certain period.
• Whenever you use the cable locator, the related safety specifications in electronics
industry must be abided by.
USE
• This cable locator can be directly used for live parts, but do take insulation measures in
accordance with industrial safety codes to avoid electric shock and hurt.
• To avoid electrical shock, the valid safety and VDE regulations regarding excessive
contact voltages must receive utmost attention, when working with voltages exceeding
120V (60V) DC or 50V (25V) rms AC. The values in brackets are valid for limited ranges
(such as medicine and agriculture).
• Measurements in dangerous proximity of electrical installations only under the direction
of a responsible electrician.
• When the product is used for testing a live line, do ensure the test lead has been taken
down from the tested object before connecting or taking down the test lead of the
transmitter, and remind the surrounding persons to be well protected.
•
As the connection of the transmitter with the mains may generate circuit current of
milliampere level, in live condition the Grounding hole of the transmitter can be only
connected with a neutral conductor. If transmitter connection is realized from the phase
towards the protective conductor, the functional safety of the protective conductor must
be tested first, in compliance with DIN VDE 0100. The reason is that when connecting the
transmitter from phase towards ground, all parts being connected to the earth may be live
in the event of an error (if the earth resistance does not comply with the prescriptions).
• When the transmitter is connected with live mains, if the Grounding hole of the transmitter
is connected with protective ground phase, the current leakage (if any) in the power
supply line may join the circuit current of the transmitter, leading to tripping of the leakage
circuit breaker, i.e. tripping of FI/RCD.
• If the operator's safety is no longer ensured, the instrument is to be put out of service and
protected against use. The safety is no longer ensured, if the instrument:
◦ Shows obvious damage.
◦ Does not carry out the desired measurements.
◦ Has been stored for too long under unfavorable conditions.
◦ Has been subject to mechanical stress during transport.
• The instrument may only be used under those conditions and for those purposes for
which it was conceived. When modifying or changing the instrument, the operational
safety is no longer ensured.
• To avoid damage, this device should be protected against excessive mechanical vibration
during handling or use, especially dropping.
• Only professionals are allowed to calibrate and repair this instrument.
• When using the instrument, the rated voltage of the tested line should not exceed the
rated voltage specified in the technical specifications of this Cable Locator.
• Keep the instrument off direct sunlight to ensure perfect functioning and long service life.
• If the instrument is subject to an extremely high electromagnetic field, its functioning
ability may be impaired.
MAINTENANCE
• If the detector is suspected of malfunctioning, please confirm that the electrical amperage
of the battery is sufficient and the test lead is not broken.
• There is a fuse within the transmitter. If it is damaged, please replace it with a fuse of
the same model. This fuse is single metal wire fast-melting type, so do not replace it
with a helical metal wire of delayed type, otherwise the transmitting power and safety of
apparatus cannot be guaranteed.
CLEANING
Use a rag dipped with clean water or neutral detergent to wipe the transmitter, and then use
a dry rag to wipe it again.
• Before cleaning work, please make sure that the equipment has been turned off, and all
the circuits have been cut off.
• During cleaning work, please do not use benzene, alcohol, acetone, ether, ketone, thinner
or gasoline, which would make the equipment deformed or decolored.
EN
• After cleaning, use the equipment again when it is completely dry.
REPLACING THE BATTERIES
If the battery symbol on the display flickers, and the buzzer gives warning, then the battery
must be replaced.
Steps to replace the battery (of the transmitter or the receiver) are as follows:
• Turn off the equipment and cut off all the measuring circuits.
• Unscrew the back of the equipment, and take out the battery cover of the equipment.
• Take out the battery used up.
• Install a new battery according to correct polarity.
• Put back the battery cover and fasten the screws.
Warning
When inserting or replacing the battery, please do pay attention to the correct polarity of
battery. If the polarity of battery is incorrect, the equipment will be damaged. Furthermore,
explosion or fire may be caused.
Do not connect the two poles of the battery with a conducting wire, and do not throw the
battery into fire, otherwise, there may be risk of explosion.
Please do not try to dismantle the battery! The electrolyte contained shows strong
basicity, which has the risk of causing corrosion! If the electrolyte contacts skin or clothes,
use fresh water to wash the relevant parts. If the electrolyte enters the eyes, use fresh
water to wash the eyes immediately, and see a doctor as soon as possible.
Notes:
• Only the battery specified in the technical parameters table can be used.
• If the equipment will not be used in a relatively long time, take out the battery within it.
• When disposing the used batteries, please abide by the existing regulations on the
recovery, reuse and disposal of batteries.
