Adjusting the LCD screen
The control unit uses a graphical Liquid Crystal Display.
The optical performance of the display changes with temperature,
light conditions and age.
There is a built-in automatic compensation for temperature changes.
Still, from time to time, it may be necessary to adjust the display.
Automatic Backlight Shutoff
To preserve LCD lifetime, the display automatically shuts off after
the predefined amount of time, if no action has been observed in that
period.
The display turns on again at any key press, or if an event occurs in
the system.
Note:
The terminals 61 and 62 can be configured as LCD Backlight
On. A 0V on the terminal will trigger the LCD Backlight On.
Contrast
Contrast is automatically compensated for with temperature.
If however the display seems dim or unclear, it may be necessary to
adjust it. Access the menu and select Contrast to adjust.
The new setting is automatically stored in internal memory, and stays
resident regardless of future power loss.
