Rosemount 3490 Series Control Unit
To automatically map up to four echoes
from false targets:
1. From the Main Menu screen, select SETUP .
2. Select the transmitter (e.g. “ Tx1: 3107 ”).
3. Select ENGINEERING .
4. Select FALSE ECHO ACTION .
5. Select Auto Tank Map .
6. Follow the on-screen instruction (“ start ”) to ignore a false echo.
(Press the Enter key if prompted to change the mode to “off-line”).
7. Wait while the transmitter learns about the empty tank to ignore the false echoes. The
process takes less than one minute.
8. Select “ Quit ” to exit to the previous menu.
Note

To clear all learned false echoes, see Clear False Echoes on page 75 .

To edit existing false echo data, see False Echo Data on page 74 .

Use the “ Learn False Echo ” feature manual learning ( page 23 ).
4.2.6 Simulation of PV
The transmitter simulations automatically cycle the PV between the bottom of the tank and the
nearest measurable distance. The cycle direction is given by the name of the simulation mode
selected.
Simulation modes are:

“Run up” – cycles up, and then down, repeatedly until stopped.

“Run down” – cycles down, and then up, repeatedly until stopped.

“Run from Zero” – as “Run up” except the PV initially starts from 0.
A single cycle takes 100 seconds to complete. The Current Output responds according to the PV.
The cycling may be paused with the “pause” mode, and then re-started by selecting another
simulation mode.
To stop the cycling, select the “normal” mode.
