General Information

  • Sigma 05 is a host device (Modbus master) for up to three E+E sensing probes/measurement devices with RS485 interface and Modbus RTU protocol.
  • This Quick Guide focuses on the Sigma 05 functionality with E+E plug-and-play probes. Please make sure to review the Sigma 05 user manual at www.epluse.com/sigma05 for manual setup and other Sigma 05 features.

Plug and Play Operation Setup

  • With enabled automatic discovery function (default setting), Sigma 05 automatically recognizes E+E plug-and-play probes and their combinations according to the table below, see “Probe Combinations and Automatic Discovery”.
  • Furthermore, the assignment of the measurands to the outputs and display, as well as the scaling of the outputs is performed automatically according to the table.
  • This setup can be changed subsequently by the user as required, see “Manual Operation / Setup” below.

PLEASE NOTE

The Sigma 05 must be powered off while connecting or disconnecting probes

Manual Operation Setup

  • For manual setup, connect Sigma 05 to a personal computer running PCS10 Product Configuration Software, free download from www.epluse.com/pcs10.
  • Disable the automatic discovery function and proceed with assigning measurands to the outputs and display as well as with the output scaling. See the user manual at www.epluse.com/sigma05.E-Plus-E-Sigma-05-Modular-Sensor-Platform-FIG-1

Pin number Function

1 Supply voltage*)
2 RS485 B (D-)
3 GND
4 RS485 A (D+)
  • The supply voltage at the probe connector is always equal to the supply voltage applied to Sigma 05. <
  • Important: Choose the Sigma 05 supply voltage (in the range 15 – 30 V DC) to match the probe supply requirements.

Voltage Supply and Outputs

  • WARNING Incorrect installation, wiring or power supply may cause overheating and therefore personal injuries or property damage.
  • For correct cabling of the device, always observe the presented wiring diagram for the product version used.
  • The manufacturer cannot be held responsible for personal injuries or damage to property as a result of incorrect handling, installation, wiring, power supply and maintenance of the device.E-Plus-E-Sigma-05-Modular-Sensor-Platform-FIG-2
