4.2

Transmitters above 10 VA

When connecting a powerful transmitter, for example W32/8, G1
generator, the maximum permissible transmission current (see
section 5.0) must not be exceeded.  If it is, the internal protective
circuit is activated.  The transmission current is substantially re-
duced, as a result of which line location can no longer be carried
out.

NB:

connection to G1 generator: current 

<

 100 mA

connection to W32/8 generator: apply the
adaption of max. 10      ; and not the power
stage 32 W.

Important:

If the

 ENA

 

is heavily overloaded it may suffer

lasting damage.

4.3

Line tracing

If the location of the end of the line which is to be traced is known,
it is of assistance to the line-tracing process to disconnect all
consumers, leaving only one (a lamp, for example) connected at
the end of the line which is to be traced. This ensures that the
transmission current flows to the end of the line.

If no LED lights up (section 3.3) and the mains fuse is inaccessible,
the transmitter can be connected to the earthed wire by means of
the earthing spike. To do this the earthing spike is connected to one
pole of the galvanic transmitter output and the other pole is
connected to the socket (item 1) of the 

ENA

.
