The 702 is compatible with a number of simple switches. Figure 2-1 shows
the correct input connections to the switch terminals on the transmitter. To
ensure a 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 voltages. Use extreme caution when making contact with the
leads and terminals.
Use the following steps to wire the sensor and supply power to the
transmitter:
1. Remove the transmitter enclosure cover (if applicable).
2. Attach the sensor leads according to the wiring diagrams
3. Connect the battery.
4. Verify the connection by observing the LCD
5. Reattach and tighten the cover (if applicable).
Begin by removing the battery-side housing cover. This will expose the
terminal block and HART communication terminals. Connect the battery to
supply power for configuration.
The Rosemount 702 will receive any HART communications from a handheld
Field Communicator, or AMS. When using a Field Communicator, any
configuration changes must be sent to the transmitter by using the Send key
(F2). AMS configuration changes are implemented when the Apply button is
clicked.
AMS Wireless and Direct Connections
AMS is capable of connecting to devices either directly, using a HART
modem, or through wireless via the 1420. When configuring on the bench
using a HART modem, double click the device icon (or right click and select
Configure/Setup), then choose the Configure/Setup tab. Configure the device
settings using the Direct Connection menu. When configuring wirelessly via
the 1420, double click the device icon (or right click and select
Configure/Setup), then choose the Configure/Setup tab. Configure the device
settings using the Wireless Connection menu.
In order to communicate with the 1420 Wireless Gateway, and ultimately the
Information System, the transmitter must be configured to communicate with
the wireless network. This step is the wireless equivalent of connecting wires
from a transmitter to the information system.
Using a Field Communicator or AMS, enter the Network ID and Join Key so
that they match the Network ID and Join Key of the gateway and other
devices in the network. If the Network ID and Join Key are not identical, the
transmitter will not communicate with the network. The Network ID and Join
Key may be obtained from the 1420 Wireless Gateway on the
Setup>Network>Settings page on the web server.
