Turn the potentiometer screw counter-clockwise until the LCD screen is readable.
If information does not display after contrast adjustment, check the LCD ribbon cable
connection. Ensure the connector is securely plugged into the onboard DISPLAY connector.
If unable to see any information displayed after checking connection, call ABB technical
