10.2 Explanation of LED-Display
The visual display will be shown by green, yellow and red LED, whereas the hardness evalua-
tion will be indicated through luminescent LEDs and the functional status through flashing
LEDs.
10.2.1 Explanation of LED-status for displaying of water hardness evaluation
The optical display and evaluation are based on the pre-set threshold value.
Hereby the row water hardness is committed to 100% as absolute value. The progression of
water hardness will be evaluated accordingly.
LED-Display Evaluation Example
green LED lights up
water hardness < 80 % threshold value
threshold value = 1 %
water hardness < 0,8 %
green and yellow LED are lighting up
water hardness < 90 % threshold value
threshold value = 1 %
water hardness < 0,9 %
yellow LED lights up
water hardness reaches the threshold value
threshold value = 1 %
water hardness approx. 1
%
yellow and red LED are lighting up
water hardness < 110 % threshold value
delayed threshold value alarm
according to DIP 6 parameterization
threshold value = 1 %
water hardness < 1 %
red LED lights up
water hardness > 110 % threshold value
released threshold value alarm
according to DIP 6 parameterization
Threshold value = 1 %
Water hardness > 1 %
