  • Page 7: Introduction

    1 Introduction Thank you for choosing our wire tracer. LKZ-700 is a state of the art, high quality device that is simple and safe to operate. Nevertheless familiarization with this manual will help you avoid errors and possible problems that might oc- cur while using the device.

  • Page 8: Safety

    Connecting the device to a voltage that exceeds 500VAC can damage the instrument. WARNING: The instrument must not be used with installations or equipment situ- ated in dangerous environments, e.g. where fire or explosion hazards exists.     Sonel S.A.
  • Page 9 You have to en- sure that there are no other persons in the danger zone. After completing the task you must restore the PE or N wire connection.     Sonel S.A.

  • Page 19: E" Mode

    If there is no voltage detected or the voltage is below 9VAC and there is no way to force a current flow, a voltage mode is selected Note: In an “AUTO” mode the AUTO LED and LED(s) corresponding to the mode selected by the transmitter are on.     Sonel S.A.

    7.8 Locating Underground Dead Cables (Not in Use) Note: LKZ-700 is intended mainly for locating electrical wiring in buildings. It can be also useful for detecting underground cables. In situations when it is difficult or impossible, a specialised detector for under- ground cables should be used.
  • Page 31 If the earth resistance is sufficiently low for a suitable current to be forced by receiver’s internal power supply, the „M+E” mode or “power” „E” mode can be used. The transmitter should be then connected in the way shown in Fig.13.     Sonel S.A.
