4 │2Productdescription
2 Product description
2.1 General
The CG 150 generator is used to energise pipes for acoustic
location. The generator is therefore also often referred to as the
transmitter.
Pipes that are not electrically conductive can be made to vibrate
by the generator with a connected striker or stopper. The acoustic
signals generated in this way can be located acoustically using a
suitable system (e.g. AQUAPHON system).
A remote control is included in the generator delivery
Energising requires a striker or a stopper. A striker and stopper
can be purchased as accessories.
2.2 CG 150 generator
The generator is permanently installed in a case. An overview
with the names of the generator parts can be found on the front
cover(g.1andg.2).
2.2.1 Ports
The generator has the following ports:
●Charging socket
for connecting AC/DC adapter L or vehicle cable L
●Port for accessories
for connecting a striker or stopper
The CG 150 generator recognises the intended use based on
the connected accessory.
2.2.2 Power supply
Thegeneratorispoweredbyaspecial,permanentlyinstalled
Pb rechargeable battery. Information about charging the
rechargeable battery can be found in section 4.1.

2 Product description│ 5
2.2.3 Remote control
The remote control can be used to pause the generator (pause
function).
The signal strength can also be adjusted when using the striker.
This is not possible when using the stopper.
The remote control has the following keys:
●Arrow keys
for setting the signal strength of the striker
●Pause key
for pausing generator operation
2.3 Optional accessories
2.3.1 Striker
Thestrikerhasamovingpin,whichcanbeusedtogenerate
vibrations on water or gas pipes. These vibrations allow the pipe
to be located.
An overview with the names of the striker parts can be found on
thebackcover(g.7).
2.3.2 Stopper
A stopper can generate vibrations on water mains which allow
the pipe to be located.
Whenwateriswithdrawnfromahydrant,thewatercolumnisset
in motion. The stopper slows down the water column at intervals.
This generates noise that travels along the pipe and can be
acoustically located even at greater distances.
An overview with the names of the stopper parts can be found
onthebackcover(g.8).
2.4 Settings for energising
The following adjustments can be made to the generator when it
is switched on or to the stopper:
●Frequency
●Signal strength

6 │2Productdescription
The following settings for the striker can be adjusted on the
generator:
●Signal behaviour
Generatorsettingsarenotsavedwhenitisswitchedo󰀨.
Whenthe generatorisswitchedon,italwaysstarts withthe
lowestfrequency.Ifthestrikerisbeingused,thegeneratorstarts
with the lowest signal strength.
2.4.1 Frequencies
The frequency measures how quickly the pulses acting on a pipe
follow each other.
Various frequencies are available for energising.
2.4.2 Signal strength
The signal strength is the intensity with which pulses act on a
pipe.
A high signal strength means high energy which helps with
location e.g. across long distances or of thicker pipes.
A low signal strength is often required if location has to take place
closetothestriker.Thisisbecausesound,forexample,canbe
transmitted through the ground close to the striker.
Striker
Whenusingthestriker,thesignalstrengthisadjustedonthe
generator.
Stopper
Whenusingthestopper,thesignalstrengthisadjusteddirectly
on the stopper (signal strength controller).
2.4.3 Signal behaviour
The signal behaviour indicates the rate at which the pulses act
on a pipe.
