Page 10: Operating Principle
3 Operating Principle The Cable Locator consists of a transmitter and a receiver. The signal generated by the transmitter consists of a modulated current. Generating a magnetic field around a conductor. See figure 1. This electro-magnetic field surrounding the conductor induces a voltage within the receiver coils. -

3.5 Locating of line interruptions in the plastic-sheathed cable (one-pole application) When locating of line interruptions, the circuit must be dead; All lines which are not required must be connected to the auxiliary ground in accordance with figure 8; Connect transmitter to one lead and to an neutral according to figure 5; and Carry out this example as described in the application example. -
Page 14: Locating Of Line Interruptions Using Two Transmitters(One-Pole Application)
3.6 Locating of line interruptions using two transmitters (one-pole application) When locating a line interruption using one transmitter to feed from one conductor end, the location of interruptions may not be precisely located in case of bad conditions due to a field disturbance. The drawbacks described above can easily be avoided when using two transmitters (one from each end) for line interruption detection. -

Page 16: Locating Fuses (Dual-Pole Application)
3.9 Locating Fuses (dual-pole application) When connecting in live circuits, the safety directions must absolutely be respected. Insert into the current circuit of a multifamily residential structure within a socket between “ “ L1 and N and switch the transmitter to LEVEL I . You may assign the signal in the secondary distribution and main distribution by transmitter pre-setting LEVEL I . -
Page 17: Locating Of Short-Circuits In Conductors (Doubel-Pole Applicaion)
3.10 Locating of short-circuits in conductors (double-pole application) When locating of shrot-circuits in conductors, any existing circuits within the cable must be voltage-free; connect transmitter in accordance with Figure 10; and carry out this example as described in the application example. Note that the tracing depth for sheathed cable and conductors are different due to the fact that the individual leads in the sheathed cable... -

Page 20: Following Lines With Higher Location Depth (Dual-Pole Application)
3.14 Following lines with higher location depth (dual-pole application) If the dual-pole application is carried out on multi-wire cables, the location depth is widely limited. The reason is that the go-and-return lines are installed very closely. Thus, a strong distortion of the magnetic field occurs. The electro-magnetic field may not develop at the bottleneck. -
Page 21: Tracing Conductors Within The Soil (Single-Pole Application)
3.15 Tracing Conductors Within the soil (single-pole application) The connection is realised in compliance with Figure 15. Ensure that the current circuit is not live. Make sure that the distance between the connection to the ground and the conductor to be detected is high. If the distance is too close, no definite assignment of the signal received can be made to one conductor. -
Page 22: The Reach Will Be Improved When Seeking The Tension
3.16 The reach will be improved when seeking the tension If the transmitter is attached at the phase and the neutral coil directly gets lost the signal in the line going parallel to and back (see figure). • The range can partly lead to signal fall off when twisting the conductors among each other. -
Page 23: Sorting Or Determination Of Conductors Already Installed (Double-Pole Application)
3.17 Sorting or determination of conductors already installed (double-pole application) When sorting or determination of conductors already installed, any exisiting circuits within the cable must be voltage-free; the lead terminals must be twisted and electrically connected between each other; you need several transmitters, with different transmitter signals (1 to 7);... -
