DEVICE OUTPUT
CONFIGURATION
3-14
1. Attach any two sensors to the transmitter as shown in Figure 2-12 on
page 2-16.
2. From the Home screen, select 1 Device Setup, 3 Configuration, 1
Variable Mapping, 5 Variable Re-map to set primary, secondary, tertiary,
and quaternary variables. The communicator displays the PV, SV, TV,
and QV menus in succession.
3. Select primary, secondary, tertiary, and quaternary variables as desired.
4. Select OK after verifying the variable settings from the Variable Mapping
menu.
5. Select OK to return the control loop to automatic control. Select HOME
to return to the Home screen.
6. From the Home screen, select 1 Device Setup, 3 Configuration, 2
Sensor Configuration, 1 Change Type and Conn, 3 Sensor 1 Setup to
configure Sensor 1.
7. Set the sensor type, number of wires, damping, and units for Sensor 1.
8. Select SEND to download the new data to the transmitter. Select HOME
to return to the Home screen.
9. Repeat steps 6 – 8 for Sensor 2 using 4 Sensor 2 setup.
10. From the Home screen select 1 Device Setup, 3 Configuration, 3
Dual-Sensor Configuration, 5 Drift Alert to prepare to configure the
transmitter for Drift Alert.
11. Select 2 Drift Limit. Enter the maximum acceptable difference between
Sensor 1 and Sensor 2.
12. Select 3 Drift Damping to enter a drift alert damping value. This value
must be between 0 and 32 seconds.
13. Select 1 Drift Alert Option and select Enable Alarm or Warning only.
14. Select SEND to download the alarm setting to the transmitters.
NOTE
Enabling Drift Alert Option Warning only (Step 13) will set a flag (via HART)
whenever the maximum acceptable difference between Sensor 1 and Sensor
2 has been exceeded. If it is desired for the transmitter's analog signal to go
into alarm when Drift Alert is detected, select Alarm in Step 13.
AMS
For AMS, configure each sensor as indicated above.
Right click on the device and select "Configuration Properties" from the
menu. Select the Dual Sensor tab to configure the Sensor Drift Alarm. In
the Drift Alert box, enable the Drift Alert Option. Enter the DrftLm limit and
define the Drift Limit Units. Set damping if applicable.
Apply changes made (see "Apply AMS Changes" on page 3-5).
Device output configuration contains PV range values, alarm and saturation,
HART output, and LCD display options.
