CHAPTER 4
OPERATION
4-4
Displays of series DN-109NN, DN-119NN, DN-129NN and DN-189NN
4.2.2.4
Parameters B, C, D, E (color option)
The color option allows auto set the display color according to the value displayed. The
possible colors are: Red, Green and Yellow.
In order to be able to manage the color, 2 internal bits are used (r1 y r2) that change
according to display value. To configure the activation levels of these bits, two parameters for
each one are used. Parameter B and C configures the bit r1, and parameter D and E configure
the bit r2.
4.2.2.4.1
Parameters to define the internal bit r1.
Parameter B is used to set up the activation condition and the delay or hysteresis
Parameter C defines the trigger level. The most significant digit allows setting up a
negative value.
