proper switch connection, anchor the switch lead wires into the appropriate compression terminals and
tighten the screws.
Switch leads
If the switch is installed in a high-voltage environment and a fault condition or installation error occurs,
the sensor leads and transmitter terminals could carry lethal voltage. Use extreme caution when making
contact with the leads and terminals.
Wiring the sensor and power supply to the transmitter
Use the following steps to wire the sensor and power supply to the transmitter:
1. Remove the transmitter enclosure cover (if applicable).
2. Attach the sensor leads according to the wiring diagram
3. Connect the power module.
4. Verify the connection by viewing the LCD display.
5. Replace the cover and tighten (if applicable).

Discrete channel configuration

Remove the power module-side housing cover to expose the terminal block and HART communication
terminals, then connect the power module to power the unit for configuration.
The Rosemount 702 Transmitter will receive any HART Communication from a Field Communicator, or
AMS Wireless Configurator. When using a Field Communicator, any configuration changes must be sent
to the transmitter using the Send key (F2). AMS Wireless Configurator configuration changes are
implemented when the Apply button is clicked.
Configuring on the bench with a HART modem
AMS Wireless Configurator is capable of connecting to devices directly, using a HART modem, or with
the Gateway. When configuring on the bench with a HART modem, double click the device icon, then
choose the Configure/Setup tab (or right click and select Configure/Setup). Configure the device
settings using the Direct Connection menu. When configuring with the Gateway, double click the device
icon then choose the Configure/Setup tab (or right click and select Configure/Setup). Configure the
device settings using the Wireless Connection menu.
To check or change discrete channel configuration using a Field Communicator, enter the following Fast
Key Sequence: 2, 2, 2.

Device network configuration

To communicate with the Gateway, and ultimately the Information System, the transmitter must be
configured to communicate with the wireless network.
