2.1 System components (overview)
COMBIPHON is a modular system. The main system compo-
nents are as follows:
●CG 50 generator (permanently installed in case)
●Tapper
Oscillator for use with water or gas pipes
●Stopper (optional)
Oscillator for use with water mains
●AC/DC adapter L
for operating and charging the CG 50 generator
2.2 Power supply to the system
There are various power supply options available for the CG 50
generator:
●external power source (100 –240 V)
−AC/DC adapter L
−12 V battery via vehicle cable L (accessory)
● Pb battery (rechargeable lead acid battery), built-in and sealed
The CG 50 generator automatically starts charging / trickle charg-
ing when it is connected to an external power source. In trickle
charge mode, the battery is constantly monitored and recharged
when necessary.
Note:
SEWERIN recommends always connecting the CG 50 generator
to an external power source, even when it is not in use. This will
prevent harmful deep discharge of the battery and also means
that the CG 50 generator is always ready for use.

2 COMBIPHON system │ 5
If the battery voltage drops below 10 V and there is no external
power supply, the CG 50 generator will switch to standby mode.
In standby mode the current is less than 7 mA, and all the LEDs
will go out.

resistance. The generator is switched o󰀨.

4 Locating with the tapper │ 7
4 Locating with the tapper
The tapper causes pipelines to vibrate, which enables the line
to be located.
For the location process itself an appropriate system for acoustic
leak detection must be used (e.g. AQUAPHON system).
The tapper can be used with gas and water pipes up to 120 mm
in diameter.
Fig. 4: Tapper, attached to a house service connection
4.1 Using the tapper to locate pipes
Proceed as follows to use the tapper to locate pipes:
1. Attach the tapper to the line.
a) To do this, place the fastening chain around the pipeline.
b) Hook the fastening chain onto the tapper.
c) Using the knob on the tapper, tighten the fastening chain
until the tapper is securely positioned.
2. Connect the connection cable of the tapper to the CG 50 gen-
erator.
3. Switch on the CG 50 generator.
4. Start up the system to be used for acoustic leak detection.

8 │ 4 Locating with the tapper
5. To optimally adjust the pulses to the individual conditions,
initially turn the intensity adjuster and frequency adjuster to-
wards the centre.
6. Start locating the pipeline.
● While doing so, gradually adjust the intensity and frequency
of the emitted pulses on the CG 50 generator until they suit
the local conditions.
− Take into account the type of ground surface, the soil
density and possible background noise.
−Do not set the intensity and frequency too high if you are
locating a pipeline close to the tapper. Vibrations can, for
example, travel along the walls of buildings and make
location di󰀩cult.
7. Mark the course of the located line.
4.2 After location
Once you have nished your location work:
1. Switch o󰀨 the CG 50 generator.
2. Disconnect the connection cable of the tapper from the CG 50
generator.
3. Disconnect the tapper from the pipeline.
4. Clean and dry the tapper before storing it in the case.
NOTICE! Equipment damage possible
Moisture in the case can eventually lead to equipment damage:
● Leave the case open in a dry environment until it has fully
dried out.

5 Locating pipelines with the stopper
The stopper is an optional accessory for the COMBIPHON sys-
tem. The stopper is designed for use on water mains.
The stopper can be connected to:
●DIN above-ground hydrants
●DIN underground hydrants in conjunction with a standpipe
Fig. 5: Stopper on standpipe
5.1 Functional principle
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 noises that travel along the line and can be locat-
ed even at long distances.
For the location process itself, an appropriate system for acoustic
water leak detection must be used (e.g. AQUAPHON system).

5.2 Using the stopper to locate pipes
Note:
This section explains how to use the stopper at an underground
hydrant with a standpipe. If the hydrant is above ground, connect
the stopper directly.
Proceed as follows to use the stopper to locate pipes:
1. Connect the standpipe with ushing adapter to the hydrant.
2. Rinse the hydrant/pipeline to remove any dirt from the stop-
per. To do this, open the shut-o󰀨 valves on the hydrant and
the standpipe. As soon as the water runs totally clear, close
the shut-o󰀨 valves. The hydrant/pipeline is now rinsed.
3. Take the ushing adapter o󰀨 the standpipe.
4. Connect the stopper to the standpipe.
5. Always turn the intensity adjuster on the stopper (g. 5) all the
way to the right initially (lowest intensity).
6. Connect the connection cable of the stopper to the CG 50
generator.
7. Open the shut-o󰀨 valves on the hydrant and the standpipe.
8. Switch on the CG 50 generator.
9. Start up the system to be used for acoustic leak detection and
start the locating process.
10. Carefully adjust the pulse to the local conditions. Take into
account, for example, the ground surface, soil density and
background noise.
● To strengthen the pulse, gradually turn the intensity adjuster
on the stopper to the left.
● Use the frequency adjuster on the CG 50 generator to
change the frequency of the pulse.
11.Mark the course of the located line.
