WARNING: Use of this equipment in a manner not specified by the manufacturer may impair the protection provided by the equipment. 3 AVERTISSEMENT: L’utilisation et l’implémentation de cet équipement d’une manière non spécifiée part le manufacturier peut affecter son intégrité ainsi que sa protection WARNING: The use of any parts not supplied by the manufacturer violates the safety rating of the equipment.
Connections and Components 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. Status LEDs - The STATUS LED (green) Currently not implemented – for future use. - The ERROR LED (red) will blink to indicate an error condition.
Setup The nodes need to be set up for correct operation before being fielded. The configurable items include: - Network selection - Check-in period selection - Modbus Slave ID setting 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. AVERTISSEMENT: Les étapes de démarrage (setup) doivent être fait dans une zone sécuritaire.

Network Setting The network address can be used to create separate networks using multiple gateways (that are in close proximity with one another). The network is set using the SignalFire Toolkit. The Network Group setting is used when more than 8 networks are needed. Both the network and network group must match those of other nodes for nodes to communicate. 7 Encryption It is possible to encrypt over-the-air transmissions to prevent tampering.
System Check-In Period This setting controls how often the node will read the Modbus device and forward the register data to the gateway. Modbus Slave ID The Modbus Slave ID must be set with the SignalFire Toolkit. Each remote device connected to a SignalFire Gateway must have a unique Modbus Slave ID. Turbine Meter Connection The Flow Totalizer is supplied with a 1” NPT Union to allow it to be directly mounted to a standard turbine flowmeter.
Timebase Units The Timebase units configure the units used for the flow rates. For example, if the volume units are set to ‘gallons’, and the timebase units are set to ‘minute’, the flow rates will be reported as gallons/minute. Timebase units available are: • • • • 9 Seconds Minutes Hours Days K-Factor Units / K-Factor The K-factor units set the units that the flow meter uses for its k-factor.
Local Display The Flow Totalizer has a local LCD display (with back-light) that allows for easy viewing of the flow totals and flow rates. The display is powered on only when the button under the display is pressed. Pressing the button when the display is on, cycles through the various information screens. The display and backlight will automatically turn itself off after 30 seconds. LCD Always on The default operation of the LCD is for it to time out and turn off after 30 seconds.
Remote Modbus Register Mapping The Flow Totalizer 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. Modbus Registers Every check-in period, the sensors are read and data is sent to the gateway.
Internal Lithium Battery Replacement Battery Packs can be changed with the node in place. 1 2 3 4 5 6 7 12 Open the cover. Slide the power switch to the off position Unplug the battery from the PCB, by depressing the locking clip on the connector. Remove the battery from the clip and replace with new battery. Connect the battery to the main PCB battery connector. Slide the power switch to the on position. Close and snap shut the enclosure cover.
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.
Configuration / Debug WARNING: Only connect to the debug port in a safe area! Ensure that the maximum voltage applied to the configuration port is less than 5 VDC! AVERTISSEMENT: Branchez le port de déboggage que dans une zone secure. Assurez-vous que la tension électrique sur le port de configuration soit moins de 5 volt DC. Debug and configuration information is available if a connection is made via the debug port on the main board.
