9 Error messages
Please note: Never open the device to find faults and do not
attempt to replace components yourself. Incorrectly performed
repairs can result in danger for the user and the system. This
will also invalidate all warranty claims.
When the device detects faults or impermissible operating states, this is
indicated by a flashing error code on the display.
Errors are basically either temporary faults, e.g. temporary overloading of
the device, or serious system errors that require external intervention.
Since multiple errors cannot be displayed at the same time, the error with
the highest error number (priority) is always displayed first. If multiple errors
exist, then the next error code is not displayed until the higher-priority error
has been fixed.
The error codes have the following meanings:
Display Meaning Cause / Remedy
Communication error
with the internal stor-
age (EEPROM).
Disconnect the load, solar
modules and battery. Re-install
the device. If the error recurs,
then please contact your
specialist dealer.
Communication error
on the external Steca
bus (6-pin edge con-
nector).
Check the plug connection
at the 6-pin edge connector,
check the power supply and
check for correct functioning
of external expansions.
If the error recurs, then please
contact your specialist dealer.
Short circuit in
external temperature
sensor.
Check the contacts of the
2-pin edge connector and
remove the short circuit.
Check sensor.
Overtemperature.
The controller has
switched off the
load due to internal
overheating.
Allow the controller to cool
down. Check for possible
causes of overheating (mount-
ing location, other heat
sources). Possibly reduce the
charging current or load cur-
rent. Make sure the controller
is adequately ventilated
Battery voltage too
low.
Voltage < 10.5 V or
< 21.0 V.
Check installation. Check the
battery voltage and manually
recharge the battery if neces-
sary. Loads directly connected
to the battery can cause deep
discharge!
Battery voltage too
high.
Voltage > 15.5 V or
> 31.0 V.
Check installation. Check the
battery voltage and check any
additional charging sources if
present.
Excessive load cur-
rent. The permissible
load current of the
controller was
exceeded, causing
the load output to be
switched off.
Reduce the load current at the
load output.
The load may cause current
peaks.
Try reconnecting the load.
