Arithmetic mean value, electronically controlled according
to the charging reference line IU
protection, open-circuit protected
Nominal current (see charging reference line)
at 35°C, above this, automatic power reduction
Battery I
Smart Charge 20
≤ 5 A
Smart Charge 30
Residual ripple
<0,18 Vpp
Temperature-dependent control (optional)
The values of the automatic switching device refer to a battery
temperature of 20 °C. If a temperature sensor is used with the
battery, these values will vary in accordance with the battery
temperature.
High temperature –> reduction of the threshold values
Lower temperature –> higher threshold values

defective.
* Reset the flash code:
takes place automatically after addressing the cause.
** Reset the flash code:
disconnect the mains voltage after addressing the cause
and disconnect battery (approx. 1 minute).
Flashing frequency:

If this does not solve the problem, please contact the
Truma Service.
Rectification
– Check all connections are
tight.
– Pull out the female device
plug to disconnect the
device from the 230 V AC
voltage mains. Wait 15 s
– then connect the female
device plug to the device
again.
– Check all fuses and the
mains supply connection.
– The device is too warm,
ensure better ventilation
of the device.
Connect battery, or replace
battery if necessary.
Ensure there is sufficient
ventilation.
Ensure there is sufficient
ventilation.
Address defect in wiring.
– Replace temperature
sensor.
