SOLA 4000 - PCB Description

1 UPS Control Logic

In normal condition the display shows a red seg- ment rotating clockwise. During the starting phase, a blinking central segment "-" is displayed. During parameter acquisition through the serial interface, the character "A" is displayed. If more than one alarm is present, only the one with the higher priority is displayed.
