  • Page 8: Introduction

    The SePem system is used for the early detection of leaks in water pipe networks. The SePem 100 logger is ideal for mobile use as the aerial of the logger is integrated in the housing. The SePem 150 logger is designed especially for stationary operation, i.e.

  • Page 12: Operating Principle

    3 SePem system Operating principle 3.3.1 Monitoring procedure (overview) The system works according to the following principle: 1. Program the logger for the first time (see Section 5.5.3). For each individual logger, specify where it will be used to gather measurement data and at what times. 2. Install the logger at the measurement location (see Sec- tion 4.3) 3.

  • Page 13: Principles Of Leak Detection

    3 SePem system 3.3.3 Principles of leak detection Various methods are used to detect a leak. Note: Leak alerts will not be issued if there is background noise (fre- quency 50Hz or 100Hz). Please refer also to the information on interpreting measurement results and leak alerts in Section 5.5.2.3 –...

    (Fig. 1). Aerial The only difference between the SePem 100 and SePem 150 loggers is their aerial. The aerial of the SePem 100 logger is in- tegrated in its housing. The aerial of the SePem 150 logger can be unscrewed.

  • Page 15: Specifying A Device Number (Optional)

    4 SePem 100/150 loggers Specifying a device number (optional) Every Logger is assigned an 11 digit serial number by the manu- facturer before shipping. In order to simplify the job of managing the loggers (in the Master software and at the measurement location) it is possible to assign each unit a device number.

  • Page 17: Screwing On The Aerial (Sepem 150)

    Note: The aerial must only be screwed onto the SePem 150 logger. The aerial of the SePem 100 logger is integrated in its housing. The logger and the aerial are connected using a TNC plug-in connector. The antenna can be screwed directly into the threaded antenna connector.
  • Page 18 4 SePem 100/150 loggers 1. First prepare the Master for programming the loggers (see Section 5.5.3, in particular Section 5.5.3.3). 2. Activate the logger by moving a magnet over the activation switch. Fig. 3 shows the direction of movement to be used.

  • Page 19: Installing The Logger

    4 SePem 100/150 loggers 4.3.4 Installing the logger The logger is secured at the installation location using the magnet. Note: Note Section 4.3.1 and Section 4.3.2! NOTICE! Damage possible from rough handling The logger contains shock-sensitive components. ● Always place the logger carefully on the attachment point.

  • Page 20: Using Installation Adapters

    4 SePem 100/150 loggers 4.3.4.2 Using installation adapters At some installation locations it is difficult or impossible to secure the logger vertically using its magnet. In this case an installation adapter is recommended. The installation adapter is particularly useful for installing loggers horizontally. The installation adapter is available to buy as an accessory.

Using the Master in vehicles The most efficient way to program the loggers and read out data is to drive slowly through the transmission range of the loggers in a vehicle with the Master.

  • Page 23: Power Supply

    CAUTION! Risk of burning Unsuitable rechargeable batteries can overheat in the event of a short circuit. ● Use SEWERIN rechargeable batteries. ● You can use other rechargeable batteries provided they fulfil the requirements of standard EN 60950-1. Rechargeable batteries must be removed from the device for recharging and charged in an external charger.

    5 SePem 01 Master 3. Remove the disposable/rechargeable batteries and insert new ones. Ensure that the batteries are inserted with the correct polarity. 4. Replace the cover so it fits neatly into place and attach firmly with the screws. Note: The date and time will need to be reset under Master settings if it takes longer than four minutes to replace the batteries (see Section 5.5.5).

  • Page 39: Logger Communication

    5 SePem 01 Master 5.5.3 Logger communication The LOGGER COMMUNICATION is used to control the exchange of data between the Master and the logger. Data includes both measurement results and logger data (see Section 5.5.3.1 and Section 5.5.3.2). The logger communication uses different methods for data trans- mission to a single logger and transmission to multiple loggers (see Section 5.5.3.5).

    5 SePem 01 Master 5.5.3.4 Single logger Note: A radio connection must always be established between the Mas- ter and logger when working with single loggers. The Master will switch to receive mode as soon as the Single logger menu option is chosen (selected and confirmed). The LOGGER SELECTION options will appear. A selection window will be displayed (initially blank).
  • Page 45 5 SePem 01 Master Note: Only select loggers to which there is a radio connection with a good signal quality. These are loggers for which the bar in the Signal column fills at least half of the field. ● The measurement and logger data for the chosen logger will be read out.
  • Page 46 Any logger errors detected during read-out will be shown under General in the last line. The error number given will be important for any contact with SEWERIN Service.
