    Connections and Components DC-DC Module Scan/Check-in Switch Config/Debug Connector Turbine sensor Connector Status LEDs Radio LEDs Radio LEDs The Radio TX LED (green) flashes each time a radio packet is sent. This LED will blink rapidly while searching for the radio network. The Radio RX LED (red) blinks on each received radio packet.
  • Page 5 Setup The nodes need to be set up for correct operation before being fielded. The configurable items include: Network selection Check-in period selection Thermocouple mode enable All settings are made using the SignalFire Toolkit PC application and a serial programming cable. WARNING: Perform the steps in this section (Setup) in a safe location only.
  • Page 6 Network Setting The network is set using the SignalFire Toolkit. The network, network group, and corporate ID/encryption key settings must match those of the gateway for them to communicate. Encryption To protect your over-the-air data and prevent tampering, SignalFire networks come with encryption. Legacy products use a Corporate ID, but can be switched over to use an encryption key if the firmware and ToolKit are up to date.

  • Page 7: Sensor Connections

    Sensor Connections Wiring Requirements Follow these guidelines when connecting sensors to the SignalFire node. See pictures for proper wire routing examples. Cables entering the enclosure must be run as pictured. DC power cable should be run through the cable gland and gland should be tightened. The DC-DC adapter wire must be routed through the cable hold-down clamp.
  • Page 8 Due to the small signal level generated by a turbine flow meter, the signal is susceptible to noise. To minimize this possibility mount the Sentinel close to the turbine pickup and always use shielded cable. Sensor cable should be routed as shown Rev 1.7 SignalFire Telemetry...
  • Page 9 Remote Modbus Register Mapping The Sentinel Node sends data to a SignalFire Telemetry Modbus Gateway. The data that is sent to the gateway is available at the gateway in registers where it can then be read by a Modbus RTU. Consequently, the node needs to have a unique (to the network it is in) Modbus slave ID which the gateway will use to store its unique data.
  • Page 10 Mounting and Care The unit comes with a watertight ½” NPT conduit fitting on the bottom mounting plate. The Sentinel is then directly mounted to the sensor with a short section of conduit. Tighten cover screws to . Do not use power tools. Anti-seize recommended. 8 in-lbs Direct Mount to Sensor with Short Conduit This mounting method uses a short conduit run from the sensor and the unit is held in place by the conduit.
  • Page 11 Cleaning Instructions The outside of the enclosure may be cleaned with water, mild soap, and a damp cloth as needed. High pressure washing is not recommended. WARNING: Electrostatic Discharge Hazard! Care must be taken to avoid the potential of creating a change on the enclosure or antenna. Do not wipe with a dry cloth. Do not brush against the enclosure with clothing or gloves.
