No. Name Level Cause Corrective measures
F 702 RsDsp 5 Signal processor has performed a
reset.
• Contact the SMA Service Line.
F 703 TimeOut 2 Time for performing a particular task
has been exceeded.
F 704 Calib 4 The system has not calibrated.
W 705 TimeOut 1 The watchdog of the signal processor
of the master has tripped.
• Contact the SMA Service Line if
required.
F 706 TimeOut 4 The watchdog of the signal processor
of the master has tripped several
times.
• Contact the SMA Service Line.
W 707 TimeOutSlv1 1 The watchdog of the signal processor
of slave 1 has tripped several times.
W 708 TimeOutSlv2 1 The watchdog of the signal processor
of slave 2 has tripped several times.
F 710 AutoStrCnt 4 Autostart meter has expired several
times in succession.
•
Read off the pending and logged
warnings and errors and eliminate
the causes.
• Ensure that the parameter 250.01
AutoStr is set to 3.
W 713 TimeOut 1 The watchdog of the operation
control unit has tripped.
• Contact the SMA Service Line if
required.
W 715 MMCUpdFail 1 The update cannot be carried out.
The type or format of the SD memory
card is not supported.
• Copy the update file to an SD
memory card with maximum 2 GB
and with FAT-16 format.
F 716 VBATMIN 2 The measured battery voltage of the
master is below the permissible
measurement range.
• Disconnect the DC loads and
charge the battery.
The usable battery capacity may be too
small, e.g., due to aging. If a load with
high power connects, the battery
voltage collapses.
•
If DC loads are installed in the
system, install load shedding for
DC loads.
•
Ensure that all battery cells are
functional.
W 717 VBATMINSL1 1 The measured battery voltage of
slave 1 is below the permissible
measurement range.
W 718 VBATMINSL2 1 The measured battery voltage of
slave 2 is below the permissible
measurement range.
F 720 InvTmpSns 4 The temperature sensor on the
transformer of the master is defective.
• Contact the SMA Service Line.
F 721 InvTmpSns 4 The temperature sensor on the heat
sink of the master is defective.
