2.8.2.5 RCU - Brightness, Illumination
Display Contents
Configuration Mode (RCU6512)
Figure 24: "CU BRIGHTNESS"
"BRIGHTNESS":
The brightness of the LCD and push-button illumination can be
adjusted between 0% (off) and 100%.
•
Use the rotary encoder to select the brightness.
Notice:
"CU BRIGHTNESS" screen is shown only if dimming input is set to
"NONE". Otherwise the aircraft dimming bus will control the
brightness.
Figure 25: "CU ILLUM"
Illumination ("CU ILLUM")
The illumination curve shows the relation between dimming bus
voltage and brightness of the LCD and push-button illumination.
•
Two adjustable points C and D define the illumination curve.
•
Select the respective parameter by pushing the "STO" button
•
Then adjust the value in vertical (up/down) direction with the
rotary encoder.
Notice:
"CU ILLUM" screen is shown only if the "DIMMING_IN" is selected
for 5 V, 14 V or 28 V dim-bus voltage.
If the dimming voltage is not available (0 V or high impedance), the
brightness of display backlight and switches illumination change to
maximum (100%)
•
Parameter "C" is the level of minimum brightness which is set
when related trigger point of dimming voltage is reached.
•
Parameter "D" is the level of maximum brightness when
maximum dimming voltage is applied to the illumination input.
