2.1.2 Connecting the switches
The 702 transmitter is compatible with a number of simple switches. When ordered in the
optional configuration for Liquid Hydrocarbon Detection, option code 61, the 702 transmitter is
compatible with Tyco
®
TraceTek
®
Fast Fuel Sensors and TraceTek sensing cable. Figure 2-1 on
page 11 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.
Wiring the transmitter
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 4.
3. Connect the Black Power Module.
4. Verify the connection by viewing the LCD.
5. Replace the cover and tighten (if applicable).
2.2 Configuring the Device Sensor
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 702 transmitter will receive any HART communication from a handheld Field
Communicator, or AMS Wireless Configurator.
2.3 Configuring on the bench with a Field
Communicator
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 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.
