Traffic light function
The so-called 'traffic light' function is activated by setting the parameter
Assign-
ment colour change
. It serves to control external signalers by a switch output
depending on the colour change of the measuring value display.
The parameter channel 1 to channel 4 can set whether or not the respective
switch output should respond to the colour change of a certain channel or all
channels.
Example1:
External signaler for colour-change 'red' to channel 1
• A signal lamp is connected to contact K1 (switch output 1) and should shine
if the colour of the first channel changes to red.
The switching thresholds are defined when configuring the analogue input 1.
