Troubleshooting

7.1 Self-test Error Messages

After the initialization routine, the system runs through a self-test. The individual parts of the sys-
tem, such as firmware and dataset, are checked and data is read in from the power control board.
If an error continues to be ascertained, possible Remedial measures must be taken according to
the type of error.

7.2 Transient Failure

In certain operating states the inverter goes temporarily offline.
Unlike failures, "transient failures" are automatically acknowledged by the inverter which attempts
to restart once the error no longer exists.
A transient failure is indicated by the red LED alarm on the control panel flashing and remains
stored in the error memory even in the event of a power failure. See the Faults section.

7.3 Faults

Permanently programmed and parameterizable limit values are continuously monitored during on-
going operation. In order to be protected, the inverter power section is isolated from voltage supply
if a limit value is exceeded or if a failure occurs. However, the DC and AC voltages may still be
available. The corresponding fault message appears in the display.
The fault is indicated on the control panel by the red "Alarm" LED emitting steady light.
Fault messages are stored in the fault memory, where they will remain even in the event of a power
failure. The fault memory can be called up via the display. The last 100 faults are recorded in the
fault memory. The latest fault is kept at memory location S0, the oldest at S100. A new fault is al-
ways stored to memory location S0. When this happens, any fault already at memory location S100
will be lost.

7.4 Fault Acknowledgement

After shutdown due to a fault, the device remains locked against reactivation until the fault is ac-
knowledged. It is not possible to acknowledge the fault while the cause of the fault still exists. The
fault can only be acknowledged after the cause of the fault has been eliminated.
 To acknowledge the fault message, press the ESC key or turn the inverter off with the DC
switch and wait min. 30 seconds to turn the inverter ON again.
