CHAPTER 4
OPERATION
4-13
DN-109NE, DN-119NE, DN-129NE and DN-189NE display series
4.6.
Colour configuration
The colour option allows you to modify automatically the display colour according to the
present value. The possible colours are: Red, Green and Yellow.
In order to be able to manage the colour 2 internal bits are used, they change depending on
display value. Eight parameters are needed to set up the levels. Four parameters are used to define
the activation form and the activation level. The other four allow defining the colour according to a
combination of the 2 internal bits.
4.6.1.
Parameters to define the internal bit r1.
To set up the internal bit
r1
parameters
b
and
C
are used.
Parameter b is used to set up the activation form and delay or hysteresis.
Parameter C is used to set up the trigger level. The most significant digit allow setting up a
negative value.

4.6.2.
Parameters to define the internal bit r2.
To set up the internal bit
r2
parameters
d
and
E
are used.
Parameter d is used to set up the activation form and delay or hysteresis.
Parameter E is used to set up the trigger level. The most significant digit allow setting up a
negative value.
