Programming Using Local adjustment
4.3
Complete Local Adjustment
The transmitter must be fitted with the digital display for this function to be enabled.
The following functions are available for local adjustment: Constant Current, Table Points Adjustment,
User Units, Fail-safe, Current Trim and Pressure Characterization Trim, Totalization Parameters;
Address change and Some items of function INFORMATION
WARNING:
When programming using local adjustment, the transmitter will not prompt "Control loop
should be in manual!" as it does when programming using the HART

configurator.
Therefore it is a good idea, before configuration, to switch the loop to manual. And do not
forget to return to auto after configuration is completed.
Local Programming Tree
The local adjustment uses a tree structure where, by placing the magnetic tool in ( Z ) it is possible to
browse the options of a branch and, by placing it in ( S ), details of the chosen option are shown.
Figure 4.2 - Programming Tree Using Local Adjustment shows the LD301 available options.
Fig. 4.2 – Local Adjustment Programming Tree – Main Menu
Actuating in (Z) activates local adjustment. In the transmitter mode, options OPER and TUNE are
disabled; therefore, the main branch starts at option CONF.
OPERATION (OPER) - Is the option where the operation related parameters of the controller are
configured: Auto/Manual, Setpoint and Manual output.
TUNING (TUNE) - Is the option where the PID-Algorithm related parameters are configured: Action,
Kp, Tr and Td.
CONFIGURATION (CONF) - Is the option where the output and display related parameters are
configured: unit, primary and secondary display, calibration, function and operation mode.
TOTALIZATION (TOTAL) - Is the option used to totalize flow in volume or mass units.
TRIM (TRIM) - Is the option used to calibrate the "without reference" characterization and the digital
reading.
ESCAPE (ESC) - Is the option used to go back to normal monitoring mode.
