LED displays
The status of the FI is indicted by integrated status LEDs, which are visible from the outside in the
state as delivered. According to the type of FI, this is a two-colour LED (DS = DeviceState) or two
single-colour LEDs (DS DeviceState and DE = DeviceError).
Meaning:
Green indicates readiness and the present of mains voltage. In operation, the
level of overload at the FI output is shown with an increasingly rapid flashing
code.
Red
Signals the presence of an error by flashing according to the number
code of the error. This flashing code (e.g.: E003 = 3x flashing) indicates the
error groups.

SimpleBox - display
The SimpleBox displays an error with its number and the prefix "E". In addition, the current fault can
be displayed in array element [-01] of parameter (P700). The last error messages are stored in
parameter P701. Further information on inverter status at the time that the error occurs can be found
in parameters P702 to P706 / P799.
If the cause of the error is no longer present, the error display in the SimpleBox flashes and the error
can be acknowledged with the Enter key.
In contrast, warning messages are prefixed with "C" ("Cxxx") and cannot be acknowledged. They
disappear automatically when the reason for them is no longer present or the frequency inverter has
switched to the "Error" state. Display of the message is suppressed if the warning appears during
parameterisation.
The present warning message can be displayed in detail at any time in array element [-02] of
parameter (P700).
The reason for an existing disabled switch on cannot be displayed with the SimpleBox.

6.2 Diagnostic LEDs on device
The device generates operating status messages. These messages (warnings, errors, switching
statuses, measurement data) can be displayed with parametrisation tools ( Section 3.1.1 "Control
and Parametrisation Boxes / Software") (Parameter group P7xx).
To a limited extent, the messages are also indicated via the diagnostic and status LEDs.
