How to change from multidrop to point-to-point mode
• Enter supervisor mode.
• Go to Advanced Setup > Output 1 (HART) > HART Address
Advanced Setup > Output 1 (HART) > HART Address Advanced Setup > Output 1 (HART) > HART Address Advanced Setup > Output 1 (HART) > HART Address.
• Enter the value 0000 and then push [^ ^ ^ ^] to confirm.
• Push the Escape buttons ([>>>>] + [ ]) until you get the save/cancel screen.
• Select save.
• Push [^
^ ^ ^].
i Output 1 switches to point-to-point mode. The current output changes to a range of
4...20 mA or 3.8...20.5 mA (this range is specified in Advanced Setup > Output 1 (HART) >
Advanced Setup > Output 1 (HART) > Advanced Setup > Output 1 (HART) > Advanced Setup > Output 1 (HART) >
Output Range Output Range Output Range Output Range).
6.4.3 Linearisation
You can use the Linearisation Table Linearisation Table Linearisation Table Linearisation Table (menu item C.1.22) to make sure that readings are
consistently accurate.
• Go to Supervisor > Advanced Setup > Installation Setup > Linearisation Table Supervisor > Advanced Setup > Installation Setup > Linearisation Table Supervisor > Advanced Setup > Installation Setup > Linearisation Table Supervisor > Advanced Setup > Installation Setup > Linearisation Table.
• Type in the number of reference points (up to 50 points). Push [^ ^ ^ ^].
i This shows the linearisation table with default values.
• Push [>>>>] to type in new data. The device reading is given on the second line Device distance Device distance Device distance Device distance.
• Fill the tank to any given level.
• Make an appropriate reference measurement. Type this data on the line Real distance
Real distance Real distance Real distance.
• Repeat these steps until all the cells in the linearisation table are completed.
• Push [^
^ ^ ^].
• Push [>>>>] and [ ] (Esc) at the same time to exit to the "save settings" window.
• Select Save Save Save Save and push [^ ^ ^ ^].
i The device will go back to operator mode.
6.4.4 Distance measurement
The device displays distance measurements when an output function is set to
"Distance". Menu items related to distance measurement are:
• Output Function (C.3.1 or C.4.1)
• Tank Height (C.1.2)
• Blocking Distance (C.1.9)
Use the flange facing as the reference point for the 4 and 20 mA current output settings. The 4
and 20 mA current output settings are the minimum and maximum points of the measurement
scale.
INFORMATION!
The device uses the linearisation table data if Linearity Activiation
Linearity Activiation Linearity Activiation Linearity Activiation (menu item D.1.24.0) is set to
"Yes". If it is necessary to change the setting of Linearity Activiation Linearity Activiation Linearity Activiation Linearity Activiation, contact your supplier.
CAUTION!
If the distance for 4 mA is set in the blocking distance, the device will not be able to use the full
current output range.
