7.4.3. LCD screen – current failures
In case of abnormal electrical parameters during operation, PSU will indicate a failure by displaying a message
on LCD, turning on red LED on panel, activating acoustic indication (if enabled) and changing status of a dedicated
technical output..

At a given time, multiple failures can occur. To check which faults are indicated, choose current failures of PSU
screen.
To do that, press „ESC” button, use „<” or „>” buttons to choose icon and press „SET” button to confirm
