Prerequisites: Verify the Wireless Gateway is installed and functioning properly before powering any wireless devices.
Procedure:
- Using a Phillips head screwdriver, back out screws so the cover opens.
Figure 2-1: Cover screws
The diagram shows the Rosemount 802 Transmitter with screws labeled 'A' for opening the cover.
Note: The default power position is with the power module terminals exposed.
Figure 2-2: Power module configuration
The diagram shows the internal power module configuration with a plastic plug labeled 'A'.
- Remove the plastic plug from the receptacle.
- Power the device in one of two ways:
- Install the 701P SmartPower Module into the 802 Transmitter to power the device.
- Move the mechanical slider to expose the external power supply terminals and power the transmitter with a 10-30 Vdc power source.
Input voltage: 10-30 Vdc
Input current (maximum): 805 mA
Power supply must be isolated from AC mains and provide transient free DC input power to the transmitter.
Figure 2-3: External power supply configuration
The diagram shows the external power supply configuration, with 'A' indicating the power supply connection point.
2.2 Antenna Position
Position the antenna vertically, approximately 3 ft. (1 m) away from any large structure, building, or conductive surface to allow for clear communication to other devices.
Figure 2-4: Antenna position
The diagram illustrates the antenna being positioned vertically.
2.3 Plug Conduits
Procedure: Plug the unused conduit entries with supplied conduit plugs with approved sealant.
3 Provisioning & Commissioning
3.1 Provision Transmitter
Prerequisites: You must power up the transmitter before the communication device can interface with it. For HART® wireless transmitter communication via a communication device, an 802 wireless device descriptor (DD) is required.
Procedure: To obtain the latest DD, go to Software & Drivers.
Figure 3-1: Connection diagram
The diagram shows the connection terminals, with 'A' indicating the communication terminals.
Note: The Emerson 475 Field Communicator will not work as a communication device for the 802 Transmitter.
3.2 Commission Transmitter to Gateway
If you ordered the transmitter with a factory-configured network ID and join key, it should join the network with no user input. If you're unsure if you ordered the device with the factory-configured option, you can manually enter the network ID and join key to match the Gateway.
Procedure:
- To obtain the network ID and join key, go to Network → Network Settings in the Gateway user interface.
Figure 3-2: Network Settings page in Gateway user interface
The diagram shows the Gateway user interface's Network Settings page, with 'A' indicating the Network ID and 'B' indicating the Join Key.
- Use communication device or HART® modem to configure the transmitter by entering the network ID and join key, as shown in Figure 3-1.
Note: It may take several minutes for the device to join the network.

4 Terminal Wiring for Input and Output Circuits
The transmitter has three screw terminals for each channel. These terminals are labeled as follows:
- PWR OUT: Constant power out
- I/O: Switched input or output channel
- CMN: Common
Note: All eight channels have a third PWR OUT terminal that outputs continuous voltage, which can be up to 2 Vdc less than the supplied external power to the transmitter. (For example, 28 Vdc into the transmitter, PWR OUT terminal outputs 26 Vdc)
4.1 Discrete Inputs
Note: Optionally, you can use the device to invert any input to change the discrete logic state. This is useful, for instance, if a normally open switch is used to replace a normally closed switch.
Figure 4-1: Discrete input circuit
The diagram shows a discrete input circuit with terminals PWR OUT, I/O, and CMN. 'A' indicates 'Dry contact only'.
4.2 Discrete Output Switch Functionality
The host control system drives the discrete output of the 802 Transmitter through the Wireless Gateway and out to the transmitter. The time required for wireless communication from the Gateway to the transmitter is dependent on many factors, including the size and topology of the network and the total amount of downstream traffic on the wireless network. For a network that is constructed to Emerson's best practices, typical delays in communication of a discrete output from the Gateway to the transmitter are 15 seconds or less. Remember that this delay is only part of the latency that will be observed in a control loop.
Figure 4-2: Discrete output circuit
The diagram shows a discrete output circuit with terminals PWR OUT, I/O, and CMN. 'A' indicates 'External power supply' and 'B' indicates 'Load'.
4.3 Alternative Discrete Output Functionality
All eight channels have a third PWR OUT terminal that outputs continuous voltage, which can be up to 2 Vdc less than the supplied external power to the transmitter. (For example, if the external power supplies 28 Vdc to the transmitter, the PWR OUT terminal will output 26 Vdc.) Figure 4-3 shows the alternative wiring configuration.
Figure 4-3: Alternative discrete output circuit wiring circuit
The diagram shows an alternative discrete output circuit wiring, with 'A' indicating 'Load'.
4.4 Special Considerations for Multi-Output Circuits
Important: If more than one channel is connected to output circuits, it is very important that the CMN terminal of each circuit be at the same voltage. Employing a common ground for all output circuits is one way to ensure that all circuits have CMN terminals at the same voltage. If two output circuits are connected to a single transmitter with a single power supply, both input/output (I/O) and common (CMN) terminals must be connected to each output circuit. The negative power supply wires must be at the same voltage and connected to both CMN terminals.
Figure 4-4: Multiple output circuits with one power supply
The diagram shows multiple output circuits with one power supply, with 'A' indicating 'Load'.
4.5 Switching Greater Currents or Voltages
Note: Maximum switching capacity is 28 Vdc and 100 mA per channel. If you need to switch a greater voltage or current, use an interposing relay circuit.
Figure 4-5 shows an example of a circuit to switch higher currents or voltages.
Figure 4-5: Wiring an interposing relay to switch greater currents or voltages
The diagram shows wiring an interposing relay. 'A' indicates 'Power supply' and 'B' indicates 'Load'.
5 Mount Transmitter Remotely
Emerson has designed the 802 Transmitter to be installed only in the remote mount configuration, where the sensor is mounted separately from the housing and then connected to the transmitter via conduit.
Procedure:
- Install the transmitter according to standard installation practices. Make sure to use thread sealant on all connections.
- To reduce sensor wiring length, mount the transmitter centrally to all of the measurements. When installing the transmitter, make sure the conduit entries are facing downward. If using the mounting bracket (option code B6), mount the transmitter to a 2-in. (51 mm) pipe.

The diagram shows the 802 mounting bracket in a bottom view.
Postrequisites: For additional remote mounting information, see Emerson.com.
6 Grounding the Transmitter
The transmitter operates best with the housing grounded. Floating systems, however, can cause extra noise that may affect the accuracy of the transmitter. If the signal appears noisy or erratic, grounding at a single point may solve the problem. Ground the transmitter through the process connection using the internal or external grounding terminal.
