  • Page 18: Power Supply

    6 Power supply Bjong can be powered in three different ways: 1. Internal 3.6Vdc 2. Internal 8..24Vdc 3. External 8..24Vdc through POWER SUPPLY connector The internal power supply is intended to be supplied by primary (non-rechargeable) batteries inserted inside the instrument case. These are high-capacity batteries, almost completely free of self-discharge, which allow the instrument to remain active for medium-long term campaigns.

  • Page 19: Internal Connectors And Power Selector

    6.1 Internal connectors and power selector Inside the Bjong there are two power connectors (3.6Vdc e 8…24Vdc) and a power selector. The connection of any internal battery and the proper setting of the selector are made according to the customer request, so no need to be changed.

    After replacing the battery, check the device connections. 6.3 External source power supply Bjong can be supplied by an external source, compatible with the features described in its dedicated chapter. The external power supply can be accessed by using the dedicated cable, connected to the POWER SUPPLY input.

  • Page 23: Wiring And Connections

    It is possible to request pre-wired connectors with additional cable lugs necessary for your purpose from the service or from your sales representative. If the Bjong is equipped with a pressure sensor, there will also be a hole for barometric compensation (vent). A specific hydrophobic membrane is inserted inside and allows the instrument to maintain the declared index of protection (IP).

  • Page 28: Working Modes

    Battery life is highly reduced in this working mode. 9.2 Discontinuous/Low power Mode In low power Mode, Bjong is programmed to enter an energy saving mode in which any unnecessary internal and external peripherals are disconnected. In this way, the power absorption from the batteries is reduced to the minimum, ensuring greater autonomy.

  • Page 29: Data Transmission

    Data transmission can be activated both continuous and discontinuous mode. By activating this function, the Bjong will send the data via modem allowing remote monitoring of the values read. The user can choose the transmission frequency to prevent the system from being constantly connected to the Internet, with significant management costs in the case of time contracts with your telephone operator and in order to reduce the energy consumption associated with turning on the modem.

  • Page 31: App Easysetup

    11 App EasySetup Bjong is completely configurable via EasySetup, a dedicated Android app that connects to the device via Wi-Fi network. Each device has a unique ID number consisting of an alphanumeric sequence of 12 characters (numbers from 0 to 9 and letters from A to F) shown on a label stick outside the case.

  • Page 32: Installation And Update

    The installation file is provided directly by the sales network or by the assistance service. EasySetup is pre- installed if a tablet for configuration is purchased together with Bjong. Download (copy) the APK installation file to a folder of the tablet's internal memory or SD card (if any).

  • Page 33: How Does Easysetup Works

    It is possible that not all buttons or not all options are enabled and selectable according to the device in use. For example, if the Bjong does not have the integrated pressure sensor available, the corresponding button to access the configuration will not be usable.

  • Page 34: Status Bar

    “Not connected” remains, but the name of the instrument (if set) and its identification will appear in the first row. In the example shown in the figure, Bjong has the name “ind12” and unique identifier “3C950900792C”. By connecting, in addition to the instrument name (if set) and its identification, the second line will indicate the date and time set on the Bjong to which you have connected.

  • Page 35: App Settings

    (see “operating mode” of the Bjong). To prevent the tablet from turning off the screen and pausing the application, it is possible to set the keeping of the display active while using the App.

  • Page 39: Save" And "Save And Upload" Buttons

    The "save" button allows you to save the changes made only and exclusively on the tablet in use: the changes are saved only locally and not sent to the Bjong. This button is useful if you want to make multiple changes in multiple configuration tabs before loading the entire profile on the instrument.

  • Page 40: Configuration

    12 Configuration 12.1 Sensors connected to RS485 port This button on the left is used to access the settings of the RS485 port of the Bjong. There are two firmware versions of the instrument that allow different management of the port: EasySetup, based on the instrument firmware, will show different configuration screens.
  • Page 41 The Bjong connector has two pins for serial communication and two power pins whose voltage is that of the connected external battery. Before proceeding with the connection, make sure to make the correct connection of the external sensor to avoid, for example, inverting the polarity of the supply voltage.

    During installation, take care the Tom Tos is close to 100% and the quality is as high as possible. 12.2 Built-in pressure sensor Bjong could be supplied with a built-in pressure sensor. Here are different pressure sensors available, depending on ranges (from 6 to 60 bar) and on installation needs. It is also possible to use external pressure sensors to be connected to analog inputs.

  • Page 53: Analog Inputs

    12.3 Analog inputs Bjong is equipped with 2 active analog inputs, with range 4-20mA and 0-10V (user can connect to the desired signal by using the dedicated wires – see wiring paragraph). Inputs can be configured independently, in order to guarantee to be the most suitable to the installation needs.

    12.5 Digital events This section is dedicated to the of the behavior of Bjong when external digital events occur. Event 1, Event 2, Event 3: they allow the user to enable the storage of the occurrence of external digital events.

  • Page 56: Mathematical Functions

    A typical application is represented by the use with bidirectional flow meters. By appropriately connecting to digital 1 and 2 of the Bjong and enabling the mathematical difference function, it is possible to totalize the quantities of net water flow. The net value is saved on the second digital (DI2 or DI4). Another typical application could be that of having to perform the difference in flow rates between the system input and output recorded by meters with pulse output.

  • Page 57: Warm Up Times

    By setting the sampling per minute, it is easy to guess that a warm-up close to or greater than one minute is not possible: in these conditions, Bjong would not be able to go into sleep mode between one reading and another.

  • Page 58: Data

    12.10.2 Historical Data By historical data we mean all the values of the variables stored on the Bjong. Over 800,000 records can be stored on the instrument: with a sampling of 10 distinct variables every minute, there is a storage capacity of about 2 months.
