sensing cable. Figure 2-1 on page 2-3 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 voltage. Use extreme caution when making contact with the leads
and terminals.
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 Figure 3-3 on
page 3-4.
3.
Connect the power module.
4.
Verify the connection by viewing the LCD.
5.
Replace the cover and tighten (if applicable).
DEVICE SENSOR
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 will receive any HART communication from a handheld
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.
AMS Wireless Configurator
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 sensor configuration using a Field Communicator, enter
the following Fast Key Sequence: 2, 2, 2.
