Application Examples; Finding Cable Breaks - VOLTCRAFT LSG-10 Notice D'emploi

Application Examples:

Do not exceed the maximum permitted input values. Do not touch any circuits or parts
of circuits if there could be voltages higher than 50 V ACrms or 75 V DC present within
them. Danger to life! Measurements at live installations must only be performed by
technically instructed staff.
In the following, you will see more examples for the applications the cable detector can be used for.
Tracing the Cable/Finding Outlets
Switch off the fuse and power down the electrical
circuit.
The protective and neutral conductors must be pro-
perly connected.
Switch on the transmitter and connect it to phase
and protective conductor (earth) as illustrated.
Move the receiver's sensor head along the wall.
Crossing or parallel cable branches
are also indicated with this method.

Finding Cable Breaks

Switch off the fuse and power down the electrical
circuit.
Proceed as described for the test measurement.
Connect the lines you do not need to the same
socket with the earth.
Move the receiver over the wall in circling motions
until you have found the interruption.
The cable break must be high-impe-
dance (>100 kOhm).
