3. Set 2040 to the output word. The Unit will be in comparison mode and the
available input range will be from 4 to 20 mA. All the other modes will re-
main unchanged.

4. When the Unit correctly receives the command, the input word will be set
to 2040.
5. Reset 0000 to the output word.
6. The Comparison Result Flags of the input word is turned ON or OFF. In this
example, the input word is set to 0004 (PASS).

The setting method of the scaling values is explained below. Refer to 6-1 Scal-
ing Value Teaching for the method to obtain the scaling values from the teach-
ing operation.
Scales input values into desired values within a range from –9999 to 9999. X2
– Y2 and X1 – Y1 must be input (X: input value, Y: corresponding display
data). The X1 value must be different from the X2 value, otherwise the Unit
will process them as an overrange value of B000.
The following are the factory-set scaling values.
X1: 0
X2: 1000
Y1: 0
Y2: 1000
Display data
Therefore, if the Unit is operated with the factory-set scaling values with an
input range from 4 to 20 mA, an input of 4 mA will be regarded as 400 and an
input of 20 mA will be regarded as 2000. When the input type is "1 to 5 V," an
input of 1 V will be 1000 and that of 5V will be 5000. When the input type is
"–9999 to 9999 V," an input of 9,999 V will be 9999 and that of –9999 V will be
–9999.
