The UPPER_DISPLAY_MODE and LOWER_
DISPLAY_MODE parameter settings in the
transducer (TR) block, and the L_TYPE settings in
the AI1 and AI2 blocks determine which data items,
and their values and units, are displayed on the
LCD indicator, as shown in the following tables.
Display on Upper Row of LCD Indicator
UPPER_DISPLAY_MODE Displayed Value, Display Unit, and Display Format
FLOW RATE (%) L_TYPE of AI1 = DIRECT = INDIRECT
Value Percentage calculated from OUT.
Value and XD_SCALE of AI1
(see note 1) Percentage calculated from OUT.Value
and OUT_SCALE of AI1 (see note 2)
Unit %

Number, to one decimal place
FLOW RATE L_TYPE of AI1 = DIRECT = INDIRECT
Value OUT.Value of AI1 OUT.Value of AI1 (scaled based on
XD_SCALE and OUT_SCALE)
Unit As specifi ed by XD_SCALE.Units
Index of AI1
As specifi ed by OUT_SCALE.Units
Index of AI1
Format Determined by the value of
XD_SCALE.EU at 100 of AI1. Determined by the value of
OUT_SCALE.EU at 100 of AI1.
TEMPERATURE (%) L_TYPE of AI2 = DIRECT = INDIRECT
Value Percentage calculated from OUT.
Value and XD_SCALE of AI2
(see note 1) Percentage calculated from OUT.Value

Note 1: If L_TYPE is set to DIRECT, the following equation applies to determine the displayed percentage:
Percentage = (OUT.Value – XD_SCALE.EU at 0) / (XD_SCALE.EU at 100 – XD_SCALE.EU at 0)  100
Note 2: If L_TYPE is set to INDIRECT, the following equation applies to determine the displayed percentage:
Percentage = (OUT.Value – OUT_SCALE.EU at 0) / (OUT_SCALE.EU at 100 – OUT_SCALE.EU at 0)  100

Note 3: The unit displayed for the totalized fl ow rate (TOTAL) is the value of TERTIARY_VALUE_UNIT in the transducer block, which is
determined by the value of XD_SCALE.Units Index in the AI1 block.
Note 4: AI3 block does not display because it is the function block for fl ow calculation in the AR block.
The following units can be displayed on the LCD: m 3 /min, m 3 /h, L/min, L/h, Nm 3 /min, Nm 3 /h, kg/min, kg/h, t/min,
and t/h.
