dZac-Bfr /
dZac-Srr The changes in grid impedance are outside the permissible range
("Bfr" or "Srr" is an internal message which has no meaning for the
user).
The Windy Boy disconnects from the grid in order to avoid potential
damage or islanding. If possible, check the grid impedance and
observe how often major deviations occur. If repeated deviations
occur and this is causing "dZac-Bfr" or "dZac-Srr" errors, ask the grid
operator if they agree to a modification of the operating
parameters. Discuss the proposed parameters with the SMA hotline.
EEPROM A transfer error occurred during reading or writing of EEPROM
data. This data is not relevant for safe operation - this error has no
effect on performance.
EEPROM dBh EEPROM data is defective. The device switches itself off because the
loss of data has disabled important functions of the Windy Boy.
Contact SMA.
EeRestore One of the duplicate data sets in EEPROM is defective and has been
reconstructed without loss of data.
Fac-Bfr /
Fac-Srr The grid frequency is no longer within the permissible range ("Bfr"
or "Srr" is an internal message that has no meaning for the user). The
Windy Boy disconnects from the grid in order to avoid potential
damage or islanding. Check the grid frequency and the grid
connection at the Windy Boy. If the grid frequency lies outside the
permissible range because of local grid conditions, ask the grid
operator if they agree to a modification of the operating
parameters.
If the grid frequency lies within the tolerance range, yet "Fac-Bfr" or
"Fac-Srr" errors are still being displayed, contact the SMA hotline.
Imax Overcurrent on the AC side. This error code is displayed if the
current in the AC grid is larger than specified. Check the system
configuration and the grid conditions.
K1-Schliess /
K1-Trenn Error during relay test. Contact SMA if this error occurs often or
several times in succession.
MSD-Fac Internal measurement comparison error or hardware defect.
Contact SMA if this error occurs frequently.
NUW-Timeout Internal measurement comparison error or hardware defect.
Contact SMA if this error occurs frequently.
MSD-Vac Internal measurement comparison error or hardware defect.
Contact SMA if this error occurs frequently.
