2.1 General
The FG 150 generator can energize electroconductive pipelines
directly or indirectly. A continuous or pulsed alternating current is
transmitted. The frequency and signal strength of the generator
can be adapted to local conditions.
Tolocateapipelineenergizedbythegenerator,areceiverisre-
quired whose reception frequency can be brought into line with
the generator's transmission frequency.
The generator is permanently installed in a case. Overviews with
the names of the generator parts can be found in the front cover
(g.1tog.3).
The scope of delivery of the generator includes:
●FG 150 cable set
●Extension for cable set
●Earthing spike
Assoonasthecablesetisconnectedtothegenerator,thegen-
eratorcanenergizedirectly.Withoutthecablesetconnected,the
generator energizes indirectly.
2.2 Ports
The generator has the following ports:
●Charging socket
for connecting AC/DC adapter L or vehicle cable L
●Cable set port for connecting cable set FG 150
2.3 Settings and adjustments
Whenswitchedon,temporaryadjustmentscanbemadetothe
generator and certain settings can be saved permanently.

Toenergizeapipeline,adjustmentsmustbemadetoallowfor
the particular local requirements:
●Frequency
●Signal strength
●Signal behaviour
Whenswitchingo,thefrequency1is saved; signal strength and
signal behaviour are not saved.
The following settings are saved permanently:
●Activation state of the frequencies (deactivated/activated)
●Individually added frequencies
2.3.1 Frequencies
Various preset frequencies are available for energizing (sec-
tion 5.2).Fordirectenergizing,individualfrequenciescanbeset
up in addition to the preset ones.
Frequenciescanbedeactivated.Deactivatingcanbeusefulif,of
allthepresetandindividualfrequencies,onlycertainfrequencies
areneededfordailywork.Inthemainview(g.4)thenumber
of selectable frequencies becomes smaller by deactivation. A
desired frequency can thus be selected more quickly.

●Factory-set frequencies for direct and indirect energizing
2. Position 11 - 15

●Individual frequencies for direct energizing
Aslongasnoindividualfrequenciesaresetup,positions

and indirect energizing.

2.3.2 Signal strength
The signal strength corresponds to the output power of the gen-
erator. The maximum output power depends on the signal be-
haviour:
●Continuous signal: max. 25 W
●Pulsed signal: max. 50 W
Whether these values are actually achieved depends on local
conditions.
The signal strength can be changed in steps.
6 │2Productdescription
Current in energized pipelines
Inenergizedpipelines,thecurrentislimitedbythegenerator:
●Continuous signal: max. 0.5 A
●Pulsed signal: max. 1 A
Ifthesevaluesarealreadyreachedatmediumsignalstrength,
the generator does not increase the actual signal strength any
further. This also applies if the Up key is pressed further and an
increased signal strength is then displayed.
Safe-to-touch range
As long as the signal strength does not show more than 3 bars
(g.3,leftpicture),the generatoroperatesinthe touch-safe
range ES12. When the Noticesymbolappears(g.3,pictureon
the right) the generator operates in the ES2 range3.
NOTICE!
IntheES2range,contactbetweenmetalparts(e.g.clamps,
earthing spike) and a body part is painful but is not expected to
causeinjury.Nevertheless,theuserisresponsibleforensuring
that persons or animals do not accidentally touch the metal parts.
●Secure the work area especially carefully when working in the
ES2 range.
TogetfromrangeES2backtorangeES1,thesignalstrength

2.3.3 Signal behaviour
The generator can optionally be operated with the following sig-
nal behaviour:
●Continuous signal
●Pulsed signal
withpulsedsignal,thesignalcycleis1:2(pulse:pause).
Note:
Operation with pulsed signal extends the operating time of the
generator compared to operation with continuous signal.
The signal behaviour determines the maximum output power of
the generator as well as the maximum current in the energized
pipeline (section 2.3.2).
2.4 Power supply
Thegeneratorispoweredbyaspecial,permanentlyinstalledPb
battery. Information about charging the rechargeable battery can
be found in section 4.1.

3.5 Energizing a pipeline directly
Duringdirectenergizing,thegeneratorsendsasignalbymeans
of cable to the pipeline to be located. The prerequisite is that
a connection can be made at at least one exposed part of the
pipeline.
The following options are available for direct energizing:
●Connection via conductor loop
●Connection with earthing spike
3.5.1 Connection via conductor loop
Forconnectionviaaconductorloop,twoconnectionpointsare
required on the pipeline. The pipeline to be located must run be-
tween the two connection points.

Ifthereisonlyoneconnectionoptiononapipeline,anearthing
spike can be used.
ACAUTION! Risk of injury from tip
The earthing spike has a tip.
●
Always be especially careful when working with the
earthingspike,especiallyinthevicinityofotherper-
sons.
●Avoid dropping the earthing spike.
The earthing spike is placed in the ground. SEWERIN recom-
mends: The distance from the earthing spike to the pipeline
should be at least 3 m.
