Emerson LTM-300 - Manual

Level/Interface. A second float may be added below the first one, and the second output will be calibrated automatically. The second time interval is measured in the same manner as the first and added to the first to derive the position of the heavier float. The same six inch dead zone applies to the mea...

6.4 Start-Up for Gage-Mounted LTM Transmitters If the transmitter does not appear to calibrate properly, or has an erratic output, check the deadband of the sensor tube and ensure that the float is within the active region of the probe. The active region of the sensor tube is typically marked with 20...

When the HART Communicator is connected to the transmitter and turned on, the first screen that is seen by the user is the root menu screen. If the transmitter is configured as Level Only or Level plus Temperature, the screen to the left shows the information displayed to the user. However if the tran...

Starting at the Calibration screen, select the Zero Level Trim procedure. This procedure trims the Level digital value measurement at the position that the user desires to be the zero reference position. If the user selects Zero Level Trim from the Calibration screen, this screen will appear remindi...

The HART Communicator now requests that the level float be set to the desired level upper trim point. The second trim point can be any other level point but it is recommended that this point be as far away from the zero point as possible. When the float is at this position, the transmitter will always...

The user is then notified that the loop may now be returned to automatic control. After the user presses OK the HART Communicator returns to the Calibration screen. The HART Communicator is now at the starting screen for the Zero Temper Trim . Full Temperature Trim Starting at the Calibration screen,...

The user is then notified that the loop may now be returned to automatic control. After the user presses OK the HART Communicator returns to the Calibration screen. The HART Communicator is now at the starting screen for the Full Temper Trim. Basic Setup Procedures If a transmitter has been configured...

The next screen gives the user a choice to set the 4mA or 20mA values or to Exit the procedure. Here the user will select the 4mA menu position. The HART Communicator requests the user to set the Level (or Interface) to the position that is to provide the 4mA loop current output. When that has been ...

If the user selects Revision #’s from the Device information screen, the screen to the left will display the revisions of the transmitter. The bottom half of the list of Device information items is shown to the left. The menu entry Revision #’s will display the various revisions of the transmitter. ...
