Cable locator
3.1.5 Error detection in underfloor heating.
Preconditions:
* The circuit current must not be active.
* All lines not being used must be connected to the auxiliary ground as shown
in Fig. 3-1-5a.
* Connect both emitters (if two emitters are used) as shown in Fig. 3-1-5b.
* Proceed as described in the sample application.
Precautions
1. If there is protective material on top of the heating cables, there must be no
ground connection. If required, separate the shield from the ground
connection.
2. Full contact with the ground must be ensured, and there must be a
considerable distance between the emitter ground and the target line. If this
distance is too short, the signal and the line cannot be located properly.
SUGGESTIONS
1. During tracing along the line, the position where the signal received by the
receiver drops sharply is the location of the break.
2. Adjust the emitter power level to suit different detection radii.
3. The position of the target can be precisely located by setting the receiver's
manual mode and selecting the appropriate sensitivity.
