Installation manual New Sensorfact bridges

Overview of the product
A bridge comes with several accessories:
  • three antennas
  • a power cable
  • a 5V adapter

The function of the bridge is to receive data from the corresponding sensors through a wireless and low-power EnOcean connection, to (temporarily) store this data locally, and to upload it to our cloud platform via a network connection. This network connection can be established via Ethernet, Wi-Fi, or LTE/4G (mobile).
The bridge has an LED indicator on the “E” of the Sensorfact logo that lights up when the bridge is powered. The figure below shows the different parts:

Important considerations
To ensure correct functionality of the Sensorfact system, please take the following guidelines into account:

  • Place the bridge as close as possible to the sensors;
  • Make sure that there are no large obstacles such as large machines and/or walls in between the bridge and the transmitter of the sensors; these obstacles can obstruct the signals from the sensors to be received properly by the bridge;

  • The bridge has a white sticker with the text: 'bridge ID: XXXX'; this is essential information for Sensorfact’s support department in case of questions about this bridge;
  • Make sure you do not attach any mounting material over the stickers of the bridge;
  • Make sure a power socket is available for the bridge;
  • Do not place the bridge in a distribution cabinet – else the internet connection via Wi-Fi or LTE (4G) might not be established properly.

Installation steps

  1. Connect the antennas
    Attach each antenna (Sensors-, Wi-Fi -and LTE-antenna) to the designated socket in the bridge. Please mount all 3 antennas to ensure optimal functionality of the system.
    1. Place the Sensors antenna by screwing it to the bridge near the label 'Sensors’. The sensor’s antenna is tapered at the end and has the text ‘Sensors’ written on it.
    2. Install the LTE antenna by screwing it to the bridge at the 'LTE' label. The LTE antenna is tapered at the end and has the text ‘LTE’ written on it.
    3. Install the Wi-Fi antenna by screwing it to the bridge near the label 'Wi-Fi'. The Wi-Fi antenna is the shortest antenna. The text ‘Wi-Fi’ is written on it.
  2. Fixate the bridge with the mounting materials
  3. Power the sensor
    1. Plug the power cable into the 5V adapter at the USB input.
    2. Plug the other side of the power cable into the bridge.
    3. Plug the power adapter into the socket.
  4. Check the LED to see if the bridge is connected
    The LED can transmit the current status in three different ways:
    1. Continuously red: Installation is successful, the bridge has connected with the Sensorfact platform;
    2. Flashing green: Disk activity is taking place, for example for writing measurement data;
    3. Flashing red: The bridge is trying to connect to the network.

When a bridge is connected to the network, it can take about 20 minutes for the bridge to connect. In exceptional cases, it may take longer. You can continue to install the other bridges while the bridge is connecting.

Congratulations! The bridge is now installed. Repeat the above steps for all other bridges in the box.
