T.3.1.1 Is the status LED illuminating in orange?

Cause

The backlight burnout detection function is activated because the backlight is nearly burnt out. Or, the power supply voltage supplied to the display unit is low.

Solution

Replace the backlight. If the problem continues after the replacement, please contact your local distributor. If the status LED illuminates in orange soon after purchase, please contact your local distributor.

Measure the power supply voltage of each display unit and adjust it to the value within the Rated Voltage range specified in the manual or the Installation Guide. If the problem continues even after the power supply voltage is adjusted, please contact your local distributor.
