12 FAULT AND WARNING MESSAGES ON THE
TESVOLT TS HV 70 OUTDOOR
EVENT
DESCRIPTION
ACTION
-
Storage system
fails to start
Check the battery wiring (incorrect polarity or plugs do not contact correctly).
Check that the 2 A microfuse APU fuse (F1), which is located on the front
left of the APU HV1000-S, is working and replace it if necessary. Contact the
TESVOLT Service Line +49 (0) 3491 87 97 - 200.
W920/W936
General
General battery fault
Restart the APU HV1000-S by pressing the ON/OFF switch. Check the param-
eter settings on the SMA STPS 60.
F921/W937 -
Battery high voltage
Overvoltage in a
cell in the battery module
The active battery management system equalises the cell voltages. Battery
overvoltage or undervoltage can indicate a faulty cell. If a limit voltage
(undervoltage/overvoltage) is achieved, the battery actively disconnects in a
two-pole manner from the SMA STPS 60 by means of a DC contactor. Contact
the TESVOLT Service Line +49 (0) 3491 87 97 - 200.
F922/W938
Battery low voltage
Undervoltage in a
cell in the battery module
F923/W939
Battery high temperature
Upper temperature limit
of a cell has been reached
Decommission the unit and let it cool down to at least 25°C.
Check the wiring of the battery modules and the ventilation of the
TS HV 70 Outdoor.
F924/W940
Battery low temperature
Lower temperature limit of a cell
has not been met
Switch off the battery and increase the ambient temperature to at least 5°C.
F925/W941
Battery high temperature charge
Upper temperature limit
reached when
charging the battery
Switch off the battery and let it cool down to at least 25°C.
Check the wiring of the battery modules.
F926/W942
Battery low temperature charge
Lower temperature limit
reached when
charging the battery
Switch off the battery and increase the ambient temperature to at least 5°C.
F927/W943 -
Battery high current
Excessive current
Switch off the battery and check the battery parameters and the SMA STPS 60
parameters. Restart the battery.
F928/W944
Battery high current charge
Excessive charging current
when charging the battery
Switch off the battery and check the battery parameters and the SMA STPS 60
parameters. Restart the battery.
F929/W945
Switch contactor
Switch has
reported a fault
Restart the battery.
F930
Short circuit
Peak current is too high
Decommission the TS HV 70 Outdoor and contact the
TESVOLT Service Line +49 (0) 3491 87 97 - 200.
F932/W948
Cell imbalance
Cell voltages deviate too strongly
from each other
Restart the battery. If the fault continues, check the cell
voltages using the BatMon software and contact the
TESVOLT Service Line +49 (0) 3491 87 97 - 200.
F972
Isolation fault
DC currents in the +/- cables
differ
Check the grounding of the cabinet and APU and also the wiring. Also check
the BAT-COM wiring and the CAN bus cables.
F973
Isolation test fault
The current sensor has a fault
Decommission the TS HV 70 Outdoor and contact the
TESVOLT Service Line +49 (0) 3491 87 97 - 200.
E 201
IsoSPI connection time-out
ABO communication is faulty
Check the BAT-COM wiring.
E202
Master/slave communication fault
Communication between the
APUs in the configuration is faulty
Check the CAN bus cables.
E203
BMC master/slave error
At least one APU has a fault
Check the addressing settings, the termination and the CAN bus cable. Also
check the states of all APUs in the configuration. Restart the battery.
E205
Modules mismatch
Master/slave configuration shows
a different number of modules
Check the BAT-COM wiring. After this, start the systems individually and
check the displayed number of modules in each case.
W301/F302
Board high/max. temp
Temperature exceeded on the
BMC board
Switch off the APU and allow it to cool down.
W947
BMC internal
Internal fault in the
controller
Restart the battery.
NOTE: For further assistance or in the event of persistent faults, please email [email protected]
or contact the TESVOLT Service Line +49 (0) 3491 8797 - 200.
