9.1.3 Process Data

Fig. 4 Process data window
The Process Data section of the setup software allows the user to view
the current output of the level transmitter in the engineering units and log
data to a file.

9.1.4 Output Setup

The Output Setup section of the setup software allows the user to change
the engineering units, mapping of variables to Loops, and set the 4 and
20 mA set points.

9.1.4.1 Output

Fig. 5 Ouput window
The Output allows the user to select the Temperature Units and Length
Units. The Temperature units will only work if the level transmitter was
ordered with temperature sensing capability. The Temperature and Length
units will change on the display and over HART
The Output Mapping can be changed by changing the selected variable for
PV, SV, and TV. PV is mapped to Loop 1 and the selected process variable
will modulate the Loop 1 current when selected. SV is mapped to Loop 2
and the selected process variable will modulate the Loop 2 current when
selected. TV is not mapped to a Loop and is only viewable via HART
® communication.

9.1.4.2 Calibrate

Fig. 6 Calibrate window
Calibrate allows the user to change the set points for levels and tempe-
rature. The user can Read and Write the 4 mA (Zero or LRV) and 20 mA
(Span or URV) independently for each variable. The values need to stay
within the active range of the level transmitter or else the 4 and 20 mA
set points cannot be reached and a tank can overflow or run dry. Do not
modify the Offset field.

9.2 Handheld Programming

MTS is working on creating a handheld DD file. Once it is released this
section will be updated with more information. Please contact Technical
Support with any questions.

9.3 Programming from the Display

The factory password for entering the display is 27513.
9.3.1 Data from Device
Display
Allows the user to select if the display shows engineering units, mA, or
percent full.
Units
Allows the user to change the selected Length Units and/or Temperature
Units.
Set Points
Allows the user to change the 4 and 20 mA set points in two ways. The
user can select Prd LRV (4 mA), Prd URV (20 mA), Int LRV (4 mA), and
or Int URV (20 mA) to enter the desired location for the set points in
engineering units. Alternatively the user can use Prd Current LRV, Prd
Current URV, Int Current LRV, and/or Int Current URV and move the float
to the desired location of the set points while setting the 4 and 20 mA
locations.
Alarm Select
Allows the user to choose between a High Alarm (>21 mA) and a Low
Alarm (<3.6 mA) for software alarm faults. The default setting is Low
Alarm. MTS complies with NAMUR NE 43.
Signal Strength
Allows the user to view the strength of the return signal for the product
