9.5 Messages on the display and the “Fault” LED
Many fault signals indicate a fault in the grid. They are not operational faults of the inverter. The minimum triggering
levels are determined by standards. The inverter must switch off if the permitted values are undershot or exceeded.
9.5.1 Display of status and fault messages
Display Fault LED (red)
FS (fault status) ON
• Fault signal relay has switched.
• Feed-in was ended due to a fault.
OS (operating status) OFF
• The fault signal relay deenergizes again.
• The inverter feeds back into the grid again
after a country-specifi c time period.
On the display you can fi nd details regarding the fault or operating status or the data that was recorded through the
RS485 interface.
Status and fault signals
The following table lists the possible status and fault signals that the inverter shows on the LCD and the LEDs.
Status Display Explanation Action
OS 1 Waiting for feed-in Self-test: The grid parameters and
generator voltage are being checked. - -
OS 2 Generator voltage
too low Insuffi cient generator voltage and
power,
status before the transition to night
shutdown
