10.2 Resetting the Fault Display
After a reset, the SMA PV Offset Box checks whether there is still any fault present. After a waiting
period, the display is updated. Any faults still present will be re-displayed via red LEDs. The display
of previous faults via yellow LEDs will be deleted.
You can only reset the LED fault display by pressing the reset button. A grid failure or AC-side
disconnection of the SMA PV Offset Box will not influence the LED display.
1. Press the reset button on the bottom of the SMA PV Offset Box.
☑ The fault display is reset.
2. Wait 6 minutes.
3. Read off the LED display again.
☑ The green LED on the SMA PV Offset Box is glowing or flashing. The SMA PV Offset Box is
in operation.
✖ One or more LEDs are glowing red or all LEDs are off.
A fault has occurred.
• Eliminate the fault and reset the fault display.
