    Refer to Safety Data Sheets (SDS) precautions from your solution supplier. Water Pre-Prime All LMI pumps are pre-primed with water when shipped from the factory. If your solution is not compatible with water, disassemble the Pump Head Assembly. Thoroughly dry the pump head, valves, O-rings, balls and diaphragm.
  • Page 4 PRECAUTIONS Back Pressure/Anti-Syphon Valve If you are pumping downhill or into low or no system pressure, a backpressure /anti-syphon device should be installed to prevent over pumping or syphoning. Contact your LMI distributor for further information. Electrical Connections WARNING: To reduce the risk of electrical shock, the metering pump must be plugged into a properly grounded grounding-type receptacle with ratings conforming to the data on the pump control panel.

    MODBUS SOFTWARE DEFINITION 4.0 Modbus Software Definition Start Hex Quantity Type Description Address 0x0001 Coils Coils are used to execute basic commands such as toggling on/off status, setting operating mode, or setting units. 0x0001 Holding Registers Holding Registers are 2 bytes each and used to read/write data such as flow rate, time, and setting values.

  • Page 9: Modbus Coil Addresses

    MODBUS SOFTWARE DEFINITION 4.2 Modbus Coil Addresses Coils are read/write single bit data fields. The coil can be set to 0xFF00 (ON) or to 0x0000 (OFF). Coils are read with Function 01 (0x01) Read Coils and written with Function 05 (0x05) Write Single Coil or Function 15 (0x0F) Write Multiple Coils.

  • Page 10: Modbus Holding Register Addresses

    MODBUS SOFTWARE DEFINITION 4.3 Modbus Holding Register Addresses The Holding Registers are read-write data fields with messages packed as two bytes per register, with the binary contents right justified within each byte. For each register the first byte contains the high-order bits, and the second contains the low-order bits. Holding Registers are read with Function 03 (0x03) Read Holding Registers and written with Function 06 (0x06) Write Single Register or Function 16 (0x10) Write Multiple Registers.
