Operating Manual
Level Cause
4 Invalid Calibration in DSP:
The system has not calibrated.
1 Watchdog DSP: The watchdog
of the signal processor of the
master has tripped.
4
Frequent watchdog fault: The
watchdog of the signal proces-
sor of the master has tripped
several times.
1 Watchdog meter on slave 1
elapsed (watchdog tripped sev-
eral times in succession)
1 Watchdog meter on slave 2
elapsed (watchdog tripped sev-
eral times in succession).
4 Autostart meter elapsed in the
device at L1 (several autostarts
in succession).
1 Watchdog OCU: The watch-
dog of the operation control unit
has tripped.
1 The update cannot be carried
out. The type or format of the
SD memory card is not sup-
ported.
2 Measuring range of battery
voltage exceeded in device
at L1: Battery voltage at the
master is below the permissible
measurement range.
1 Measuring range of battery
voltage exceeded in device
at L2: Battery voltage at slave 1
is below the permissible mea-
surement range.

10 Troubleshooting
Corrective measures
• Contact the Service (see Section 16
"Contact", page 161).
• Contact the Service, if required (see
Section 16 "Contact", page 161).
• Contact the Service (see Section 16
"Contact", page 161).
• Ensure that the parameter 250.01
AutoStr is set to 3.
• Read off the pending and logged
warnings and errors and eliminate
the causes.
• Contact the Service, if required (see
Section 16 "Contact", page 161).
Copy the update file to an SD memory
card with maximum 2 GB and with
FAT-16 format.
• 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.
