Silent Run"
noise-optimised operation (night operation)
The internal cooling fan of the unit will be set to constant lowest noise, steady speed.
All light-emitting diodes will be switched off, only the current display "Current" will still be lighting weakly.
Of course, all charging and control functions continue working internally to the full extent.
The lower cooling capacity might effect a slightly reduced charging capacity. **
Reactivation of the display and thus of the full charging capacity:
is possible at any time by pressing the key again.
Automatic reactivation after 10 hours by integrated timer (end of nighttimes)
**
With the most powerful unit type Pb 1230 SMT 2B the charging capacity will be limited to approx. 80 % (AC limit).
Operation of the unit is also possible, if the local 230 V mains only offers smaller capacity rates (weak protection of the
parking lot with only 2 amperes, shore power supply or Marina, generator operation).

Special charging program
"Li Storage"
for
LiFePO4 maintenance (
seasonal
operation)
This charging mode can only be activated, if the "charging program LiFePO4" had been set. It cannot be activated for lead
charging programs!
Press the key > 4 sec. until the light-emitting diodes "Battery Full" and "Main Charging" will be flashing quickly. Then,
release the key:
After that,
"Battery Full" and "Main Charging" are flashing slowly and alternately,
the charger had switched, ready.
This special charging program automatically maintains an advantageous charging state of 50-80 % of the LiFePO4 battery
when the vehicle is stopped. This charging state is advantageous for the battery lifetime and simultaneously supplies the 12
V consumer loads of body and systems, such as alarm systems, WLAN etc., as well as the vehicle's starter battery and the
consumer loads in idle mode.
Note: For reasons of safety, the charger always remains in this operating mode, even in case (inadvertently) of power
failure, engine start, higher charging of the battery (batteries) by the solar system, high 12 V consumer current rates etc., in
the meantime. Of course, the temperature control for the LiFePO4 battery and the internal monitoring functions of the
equipment continue working.
The lighting intensity of the LED "Current" will be reduced or increased depending on the supplied current intensity. It will
turn off, if the charging current rates are approx. < 0.2 A.
At the beginning of this charging mode there are two possibilities in practice:
1.
Low charging state of the battery: The LED "Current" is lighting:
The unit charges the battery to the desired charging state of 50-80 % and keeps it constant.
Further action is not required.
2.
High charging state of the battery: The LED "Current" is turned off:
The charger cannot discharge the battery by itself. This is effected by the 12 V consumer loads being continuously
connected.
The battery will be discharged until the charger automatically "catches" it and the consumer loads. From this moment, the
desired charging state of 50-80 % is kept. Further action is not required.
Depending on the consumer loads and the battery size, this can take long, possibly days. However, the process is executed
automatically.
Users in a hurry can drop the battery with strong consumer loads, until the LED "
Current
" is lighting
intensively
for an
extended period or an existing battery computer indicates approx. 60-70 % charging state. The system levels off
automatically over the coming weeks.
Return
to the standard LiFePO4 charging program:
This is solely and
only
possible by a
longer keystroke
of min.
4 sec.
until the LEDs "Battery Full" and
"Main Charging" will be flashing quickly. Then release the key. Ready. Actions, such as withdrawal of the mains plug, do not
have any effect (see above).
It follows the automatic full charging process with the charging program LiFePO4. End of season break.
Option: Remote Control
(Plug "Remote Control")
If the charger has been installed in a difficult to access location, the
Remote Control S for
Automatic Charger (Order No. 2075)
can be used for remote control of the charging process
(plug-and-go connection cable of 5 m length is included in the delivery scope).
Connection:
Just insert the plug of the remote control into the tip jack "Remote Control" of the charger.
Function:
The remote control is equipped with the same pilot lamps (light-emitting diodes)
as the charger.
Switch Function:
Position "ON": Charger works with full charging capacity.
Position "OFF": Ensures silent operation on board by means of the function "silent run",
noise-optimised operation (night operation), see above.
