COMBIPHON system

System components (overview)

COMBIPHON is a modular system. The main system components are as follows:

Fig. 2: Ports on case

• 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

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 charging 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.

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.

CG 50 generator

The CG 50 generator is permanently integrated in the case and cannot be removed (fig. 1).

Fig. 1: CG 50 generator in case with accessories
There is an optional remote control available for the CG 50 generator.

Controls and displays

For an overview including the names of all the controls and displays, see the front cover flap (fig. 3). The frequency and intensity of the signal used for the location process are set using the knobs on the CG 50 generator.

The LEDs on the control panel indicate the following operating statuses:

LED

| Colours| Signal|

Operating status

---|---|---|---
Tapper| red| constant| tapper connected
Stopper| red| constant| stopper connected
Disposable battery| green| constant| generator switched on
flashing| battery charging
double flashing| trickle charge
red| flashing| undervoltage
Frequency| red| flashing| generator generating pulse

Switching the generator on and off

The CG 50 generator is switched on and off using the on/off knob.

• Turn the on/off knob to the right until you overcome the slight resistance. The generator is switched on.
• Turn the on/off knob to the far left until you overcome the slight resistance. The generator is switched off.

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

Using the tapper to locate pipes

Proceed as follows to use the tapper to locate pipes:

1. Attach the tapper to the line.

2. a) To do this, place the fastening chain around the pipeline.

3. b) Hook the fastening chain onto the tapper.

4. c) Using the knob on the tapper, tighten the fastening chain until the tapper is securely positioned.

5. Connect the connection cable of the tapper to the CG 50 generator.

6. Switch on the CG 50 generator.

7. Start up the system to be used for acoustic leak detection.

8. To optimally adjust the pulses to the individual conditions,
   initially turn the intensity adjuster and frequency adjuster towards the centre.

9. 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 difficult.

10. Mark the course of the located line.

After location

Once you have finished your location work:

1. Switch off 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.

Locating pipelines with the stopper

The stopper is an optional accessory for the COMBIPHON system. 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

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 located even at long distances.
For the location process itself, an appropriate system for acoustic water leak detection must be used (e.g. AQUAPHON system).

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 flushing adapter to the hydrant.
2. Rinse the hydrant/pipeline to remove any dirt from the stopper. To do this, open the shut-off valves on the hydrant and the standpipe. As soon as the water runs totally clear, close the shut-off valves. The hydrant/pipeline is now rinsed.
3. Take the flushing adapter off the standpipe.
4. Connect the stopper to the standpipe.
5. Always turn the intensity adjuster on the stopper (fig. 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-off 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.

After location

Once you have completed the location process:

1. Switch off the CG 50 generator.

2. Close the shut-off valve on the hydrant.

3. Disconnect the connection cable of the stopper from the CG 50 generator.

4. Remove the stopper from the hydrant.
   If using on an underground hydrant:

   • a) Remove the stopper from the standpipe.
   • b) Remove the standpipe from the hydrant.

5. Thoroughly clean the components of the stopper.

6. Dry all parts or let them dry naturally.

7. Clean and dry the stopper before storing it.

NOTICE!
Functional disturbances possible as a result of corrosion
To prevent the corrosion of surfaces:

• Make sure the system is as dry as possible when storing it.
• Only reassemble the stopper when it is dry or immediately before next use.

Cleaning the stopper

To ensure the functionality of the stopper, thoroughly clean and dry the stopper after every use.
