Fault Cause of fault Explanation/remedy By
Additional devices
that are connected
via the poten-
tial-free contact
suddenly start up,
even though the
“priwatt” function is
deactivated and the
inverter indicates an
error.
The potential-free
contact connects
to indicate an
error.
If the “priwatt” function is not activated, the potential-free
contact functions as a fault signal relay and therefore indi-
cates errors. However, if additional devices that are provided
for the “priwatt” function are connected to the inverter via the
contact, they can still start up when the inverter experiences
an error, because the contact is connected at that point in
time. If you deactivate the “priwatt” function, we recommend
that you disconnect devices from the inverter that were con-
nected for this function.

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 triggering levels are
defined in standards, e. g. VDE0126-1-1. The inverter shuts down if the values exceed or fall below the approved levels.
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 releases again.
• The inverter feeds back into the grid again after a coun-
try-specific time period.
Details regarding the fault or operating status can be found either on the display or in the data that was recorded
through the RS485 interface.
9.5.2 Status and fault signals
The following table lists the possible status and fault signals that the inverter shows on the LCD and the LEDs. For
the status, consult the data that is logged via the RS485 interface.
BS = operating status, FS = fault status;
B = Action of the operator
E = The indicated work may only be carried out by an authorised electrician.
K = The indicated work may only be carried out by a service employee of KACO new energy GmbH.
