9.2 Fault messages
If a fault develops, the Windy Boy generates a message, which is dependent on the
operational mode and the type of fault
.
Fault code
Description
Bfr-Srr
NUW-FAC
NUW-UAC
NUW-ZAC
Internal measurement comparison fault: the Windy Boy found too
large a difference between values provided by the BFR and SRR.
Contact SMA.
dZac-Bfr
dZac-Srr
The changes in mains impedance exceed the permissible range
("Bfr" or "Srr" is an internal message that has no meaning for the us-
er).
The Windy Boy disconnects from the mains grid or stand-alone grid,
to avoid potential damage. If possible, check the mains impedance
and check how often major deviations occur. If repeated variations
occur and this is causing "dZac-Bfr" or "dZac-Srr" faults, ask the elec-
tricity provider if they agree to a modification of the operating pa-
rameters. Discuss the proposed parameters with the SMA hotline.
EEPROM
A data transfer fault occurred during reading or writing of data from
the EEPROM, the data is not relevant for safe operation - this fault
has no effect on performance.
EEPROM
dBh
Data EEPROM is defective, the device has switched itself off because
the loss of important functions has disabled the Windy Boy. Contact
SMA.
EeRestore
One of the duplicate data sets in the EEPROM is defective and has
been reconstructed without loss of data.
Fac-Bfr
Fac-Srr
The mains frequency has exceeded the permissible range ("Bfr" or
"Srr" is an internal message that has no meaning for the user). The
Windy Boy disconnects from the mains grid or stand-alone grid, to
avoid potential damage. Check the mains frequency and mains con-
nections on the Windy Boy. If the mains frequency lies outside the
permissible range because of local conditions, ask the electricity pro-
vider if they agree to a modification of the operating parameters.
If the mains frequency lies within an acceptable range and "Fac-Bfr"
or "Fac-Srr" faults are still being displayed, please contact the SMA
hotline.
Imax
Overcurrent on the AC side. This fault code is displayed if the current
in the AC network is larger than specified. Check your system config-
uration and the mains supply conditions.
