Display series DN-107P
4.4. 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.
The parameter number that defines the activation mode and the activation level
changes depending on the function used.
In the displays with relay output, the counter and chronometer functions use the same
parameters for the colour than the relay output. So, the colour change must be related with the
relay activation
The following table defines the parameters depending on the function used in the
display.

4.4.1. Using functions BCD, tachometer. binary or digit by digit
4.4.1.1. Parameters to define the internal bit r1.
To set up the internal bit r1 parameters A1 and S1 are used.
Parameter S1 is used to set up the activation form and delay or hysteresis.
Parameter A1 is used to set up the trigger level. The most significant digit allows setting
up a negative value.
Parameter S1
Left Digit Control bit Right Digit Set/Reset
0 ON if Value > Parameter A1 0 No delay / No hysteresis
1 ON if Value < Parameter A1 1 Delay 1s
2 Always OFF 2 Delay 2s
3 Delay 4s
4 Delay 6s
5 Delay 10s
6 Hysteresis = 2
7 Hysteresis = 4
