Be especially vigilant, especially in environments with an increased risk of accident (e.g. traffic). ● Do not use the product if it is damaged or faulty. ● Protect the ports and sockets against dirt, and electrical ports in particular against moisture. ● Proceed with extreme caution in the vicinity of electrical lines. 1 Introduction │ 3...
Product description 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.
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: ●...
The following settings for the striker can be adjusted on the generator: ● Signal behaviour Generator settings are not saved when it is switched off. 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.

Striker When using the striker, the generator can optionally be operated with the following signal behaviour: ● Steady signal ● Discontinuous signal Signal Signal curve Steady Discontinuous Stopper When using the stopper, the generator always emits a steady signal. 2 Product description │ 7...
Energising pipes NOTICE! When the lid is open, moisture can get into the case. Permanent moisture can cause damage to the generator and the case insert. ● When wet, open the generator case only as long as necessary for operation. Switching the generator on and off Switching on ● Press the ON/OFF key for approx. 1 second. A startup screen appears briefly on the display, indicating the firmware version. After that, the generator is operational (fig. 3). Switching off ●...
● Press the Down key to reduce the signal strength. The signal strength display changes with each keystroke. Note: Even when no signal strength is displayed, the generator will still send pulses. 3.3.2 Signal strength of the stopper The signal strength of the stopper can be changed in steps. ● Turn the signal strength controller on the stopper clockwise to reduce the signal strength.
Fig. 4: Striker, attached to a house service connection 1. Attach the striker to the line. a) Place the fastening chain around the pipeline. b) Hook the fastening chain onto the striker. c) Clamp the fastening chain using the star knob until the striker is adequately secured to the pipe. 2.

The hydrants must meet the standards of DIN Note: The section below explains how to use the stopper on an underground hydrant with standpipe. The stopper is connected directly to above-ground hydrants. 1. Connect the standpipe with flushing adapter to the hydrant. 2. Rinse the hydrant/pipeline to remove any dirt. a) Open the shut-off valves on the hydrant and the standpipe. b) Wait until the water runs totally clear.
Using the remote control 3.7.1 Using the remote control for the first time The remote control comes with a film strip to protect the battery, which must be removed before first use. ● Pull the battery protection strip until it comes off. 3.7.2 Pause function The pause function can be used to pause operation of the generator without switching the generator off. While paused, the generator does not send any pulses. The pause function can be used for both the striker and the stopper.
The Pause symbol disappears from the display. 3.7.3 Setting the signal strength (striker only) Note: The remote control can only be used to adjust the signal strength for the striker, not for the stopper. The signal strength is adjusted using the remote control in the same way as on the generator itself (section 3.2). ●...
Maintenance Charging the rechargeable battery The battery of the generator must be charged when necessary. The typical charging time is less than 7 hours. The following is required for charging: ● AC/DC adapter L ● Vehicle cable L The AC/DC adapter and the vehicle cable are available to buy as accessories.
● Always use a clean, soft cloth to clean the display surface. ● Never use cleaning agents containing aggressive constituents (e.g. acidic or abrasive constituents) to clean the display surface. SEWERIN recommends: Always remove significant contamination immediately. 4.2.2 Cleaning the stopper The stopper must be thoroughly cleaned and dried after every use.

NOTICE! Functional disturbances possible as a result of corrosion To prevent the corrosion of surfaces: ● Only reassemble the stopper when it is dry or immediately before next use. 1. Undo the screws on the front of the stopper using the Allen key provided.
● Store the striker in the case. Servicing SEWERIN recommends: have the generator serviced regularly by SEWERIN Service or an authorised professional. Only regular servicing can ensure that the generator is always ready for use. Troubleshooting 4.4.1 Generator...
