    Base Control Box also has relays for connection to your site warning system. The relays have the same function as those in the BTD-200 sensor. You can connect your computer or server directly to the Base Control Box using either USB or Ethernet, this replaces the data connection from the BTD-200 to the computer.
  • Page 13 The Wide Area Sounder is controlled by a data link that may come from either the BTD-200 or the Base Control Box. The ability to connect to either the BTD-200 or Base Control Box is provided to make installation as flexible and easy as possible.

  • Page 14: System Configurations

    System Configurations A BTD-200 system can be put together in several ways depending on the needs of the user and the chosen equipment. This section looks at the features available to the user in various configurations. 4.2.1 Standalone Use The simplest possible configuration. The BTD-200 sensor connects to your site warning system using the built in relays.
  • Page 15 Section 4.4.3. 4.2.2 Connected Directly to a Computer The BTD-200 can connect directly to a user’s computer or a group of computers on a local network using either a wired data connection or a Radio Module link. The Lightning Works software can then run on up to five networked computers allowing lightning warnings to be displayed along with system health status.

    Warnings and Alerts. Connecting the BTD-200 to a Base Control Box does not stop you using the BTD-200 relays, indeed the relays in both the BTD-200 and Base Control Box can be used at the same time. When a Base Control Box is connected to the BTD-200, any connection to a user’s computer or network must be made through the Base Control Box USB or Ethernet connection.

    Vicinity and Distant. The three bands are represented by concentric circles centred on the BTD-200. When the size of the band is given the value is the distance from the BTD-200 to the outer edge of the band. The size of the bands can be adjusted using the Lightning Works software, the allowable values and the defaults are given in the table below.

  • Page 19: How The Relays Work

    The relays on the Base Control Box function in exactly the same way as those in the BTD-200, either or both sets of relays can be used. The way these relays operate and how they can be configured is explained in this section.

  • Page 21 The Relay inactive time is set using the Lightning Works Software. The inactive period start and end times are entered using the 24-hour clock format. The BTD-200 internal clock is used to control the switching time, make sure it is set to local time.

  • Page 22: Btd-200 Data Archive

    BTD-200 Data Archive The BTD-200 communicates with the Lightning Works software and Base Control Box by sending digital messages over the primary communications link. The Lightning Works software archives these messages on the server computer, so they can be exported at a later date. You might want to do this to see when Warnings and Alerts were generated on a particular day or to prove that you have an effective lightning warning system in operation.

  • Page 23: Sensor Installation

    SENSOR INSTALLATION Site Selection It is very important for the successful operation of the BTD-200 that it is installed at a suitable site. Please consider the following when selecting your installation site: Ideal site (gives best performance)  Flat, level ground with no obstacles higher than approximately 20cm (10”) (including vegetation) within 2m (79”) of the sensor...
