LCD Display always on?
« on: April 29, 2003, 01:00:31 AM »
I'm using 2 HMI from trilogi presently and notice something strange. Why is the LCD display Backlit always on? Will it lead to burn out of the screen?

The LCD backlight is designed to be ON all the time. If you connect the right voltage and biasing resistor it is alright to leave it on all the time.  (You must connect the 150 ohm resistor in series to the 24V power supply).
