level S1,
Disturbance
level S2
Warning (W) The inverter has displayed a warning that does not influence the
behavior of the inverter.
Time The inverter has detected an error and switches into the "Fault"
operating state.
In the process, the AC contactor and the DC switching device
open. The inverter does not feed into the grid for the defined
time.
The time specifies how long the error will be displayed on the
touch display and saved in the inverter as an error. If the time
has elapsed, the error is no longer shown on the touch display.
The inverter then checks whether the cause of the error has been
rectified.
If the cause of the error still exists after the time has expired or
the error has been acknowledged, the error is occurs again and
the inverter remains in the "Fault" operating state.
Acknowledge (A) The inverter switches to the "Fault" operating state and opens
the AC contactor and the DC switching device.
The inverter does not feed in until the error is acknowledged
manually.
When the error has been acknowledged, it is no longer shown
on the touch display. The inverter then checks whether the cause
of the error has been rectified.
If the error is no longer present, it is deleted from the memory.
If the cause of the error is still present after the error has been
acknowledged, the error occurs again.
Day change (D) The inverter switches to the "Fault" operating state and opens
the AC contactor and the DC switching device.
The inverter does not feed into the grid.
The error message is automatically reset when the day changes.
If the error has been reset, it is no longer shown on the touch
display. The inverter then checks whether the cause of the error
has been rectified.
If the error is no longer present, it is deleted from the memory. If
the cause of the error is still present after the day has changed
or after the error has been acknowledged, the error occurs
again.
Plant-spec. (C) The inverter switches to the "Fault" operating state and opens
the AC contactor and the DC switching device. The inverter
does not feed into the grid. How long the inverter remains in this
state depends on plant-specific influencing factors.
If the time has elapsed, the error is no longer shown on the touch
display. The inverter then checks whether the cause of the error
has been rectified. If the error is no longer present, it is deleted
from the memory.
Reset (R) ‒ The control is restarted. The relays are checked and the control's
voltage supply is switched off. This process requires less than one
minute. While the control is powered up, the regular waiting times
of the inverter for grid monitoring are maintained.
