HART
To set up and enable the Sensor Drift Alert feature of the 3144P with the
Traditional Fast Key sequence:
1. Attach any two sensors to the transmitter as shown in Figure 2-12 on
page 2-13.
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. After verifying the variable settings from the Variable Mapping menu
select OK.
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 Sensor Drift Alert.
11. Select 2 Drift Limit and enter the maximum acceptable difference
between Sensor 1 and Sensor 2.
12. Select 3 Drift Damping to enter a Sensor Drift Alert damping value, which
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 (through
HART) whenever the maximum acceptable difference between Sensor 1 and
Sensor 2 has been exceeded. For the transmitter’s analog signal to go into
alarm when Drift Alert is detected, select Alarm in Step 13.
