Installing the RHE46 Coriolis transmitter

Mechanical installation

Mounting on the DIN rail
Open the DIN rail lock at the bottom (1). Place the RHE46 on top of the DIN rail (2) and press it down (2). Close the DIN rail lock (4) to fix the RHE46 on the DIN

Dismounting from the DIN rail
Open the DIN rail lock (1), tilt the RHE46 forward (2) and lift it off the DIN rail (3).

Electrical installation

Connecting the RHE46 Coriolis transmitter to the RHM Coriolis sensor
Wire the RHE Coriolis transmitter to the RHM Coriolis sensor according to the corresponding wiring diagram (QR code on the side of the RHE46), e.g.:

Make sure that you connect the associated RHM to the RHE. See type plate of the RHE for the serial number of the associated RHM at “Set for”.

Connecting the power supply
The RHE46 Coriolis transmitter requires a regulated DC power supply of 12 to 24V ±10%. The power consumption is max. 4W.

1. Connect the positive DC power connection of the power supply to the +24V connection (20) and protect it with a fuse (1).
2. Connect the negative DC power connection of the power supply to the ground connection (21).
3. Connect a protective conductor to a corresponding junction point and to the connection for the protective conductor (22).

Connecting the RS485 interface
The RS485 interface is used for digital communications, for remote control purposes, and to exchange data. It uses the Modbus protocol to establish a permanent connection to a monitoring control system.
For the wiring of the RS485 interface, please refer to the wiring diagram (QR code on the side of the RHE46).
The communication settings of the RS485 interface can be read and changed via the RHEComPro software, see section 8.

Connecting the Modbus TCP / EtherNet/IP / Profinet interface
The Modbus TCP / EtherNet/IP / Profinet interface is used for digital communications, for remote control purposes, and to exchange data.
For the wiring of the Modbus TCP / EtherNet/IP / Profinet interface, please refer to the wiring diagram (QR code on the side of the RHE46).
Once the RHE46 Coriolis transmitter has been connected, it is assigned an IP address, which is required in order to connect the RHE46 Coriolis transmitter with your own network. The IP address can be read out using the RHEComPro software, see section 8.

Zero point calibration

Calibrating the zero point ensures that the measurements are accurate within the permissible tolerance.

1. Fill the RHM Coriolis sensor completely with the measuring liquid and make sure that there are no gas bubbles (liquid application) or liquid residues (gas application) in the sensor.
2. Flush the sensor until the typical process temperature is reached at the sensor.
3. Perform the zero calibration, remind the following points:
   • Make sure that the typical process temperature and pressure values are present at the sensor.
   • Make sure that there is no flow. In the best case, by closing valves before and after the sensor.

The zero point calibration can be carried out using the button on the front of the RHE (see figure below) or the RHEComPro communications software.
The zero point calibration is signaled by the flashing of the yellow and red LED on the RHE and requires a maximum of 30 seconds. As soon as the flashing stops, the zero point calibration is completed. The flowmeter is now ready for use.

Configuration

The RHE46 Coriolis transmitter is configured using the RHEComPro software. The software can be downloaded from the Rheonik website or directly from the following link:
