"D+":
Control input charging converter ON / OFF and function selection:
Two (2) operating modes for automatic ON / OFF control of the unit are possible:
1)
Connection of terminal "D+"
:
Activation of the charging converter by control signal of the vehicle:
This operating mode is to be used for the caravan living compartment via plug connections, for conventional
generators/vehicles, as well as for
EURO standard 6, 6+ vehicles
with energy management, start/stop, strongly
varying voltages of generator/STARTER batteries during energy recovery etc. Also refer to the connection plan, page 2.
Advantageous for stable operation, even with long cables between STARTER battery and charging converter in
connection with conventional generators.
Increase of the charging capacity *:
>
11.70 V
Reduction of the charging capacity *:
<
11.40 V
Switching off threshold (with continuous signal "D+") *: <
11.20 V
with delay 30 s
Recharging branch
for STARTER battery (trickle charging), if the BOARD battery is charged by a mains supply charger:
ACTIVE
2)
No connection of terminal "D+". It is left blank: Pure voltage control of the charging converter:
The unit is activated by the increased voltage at the STARTER battery due to the running engine. It will be switched off
automatically in case of a voltage drop (engine off).
This operating mode requires powerful, short cables to the STARTER battery and a conventional,
a non-intelligent generator with sufficient high and uniform charging voltage (not Euro 6).
During this operating mode the STARTER battery cannot be discharged, due to the high switching off threshold.
Note:
If voltage had been supplied to the terminal "D+" by mistake, the unit will memorize this "control by signal D+" and will expect this
signal for the further operation.
Reset:
Return to the operating mode "Voltage Control" (without "D+") is possible by
separating the unit from any
operating voltage for 30 seconds. (Separate BOARD and STARTER battery).
Increase of the charging capacity *:
> 13.30 V
Reduction of the charging capacity *:
< 13.00 V
Switching off threshold*:
< 12.90 V
with delay 30 s

BLOCKED
* Also see "Function of the Power Control at STARTER Battery and Generator", page 7.
Battery Temperature Sensor:
Connect the temperature sensor (included in the standard delivery scope) to the
terminals "TS TS"
(any polarity).
The temperature sensor controls the
temperature
of the BOARD supply
battery
.
Ensure that the installation place of the sensor is not influenced by any source of heat (engine heat, exhaust, heater
etc.)!
Lead-Acid, Gel, AGM Batteries:
Installation:
The
thermal contact
of sensor and
battery inside temperature should be well.
Thus, it should be screwed
down to the negative pole or positive pole of the battery. It is also possible to fasten it at the sidewall centre of the battery
casing.
Function:
The temperature-dependent charging voltage of the BOARD battery will be adapted automatically to the battery
temperature (automatic temperature equalization).
For this purpose, the temperature sensor measures the battery
temperature. In case of low temperatures (winter operation), the charging voltage will be increased in order to improve
and accelerate full charging of the weak battery. Sensitive consumers are protected by a voltage limitation in case of very
low outside temperatures.
In case of summery temperatures, the charging voltage is reduced to minimize the load (gassing) of the battery and to
extend the lifetime of gas-tight batteries.
Battery Protection:
In case of excessive battery temperatures (from +50 °C), the charging voltage will be reduced strongly
to the
safety charging voltage
of approx. 12.80 V for battery protection, and the maximum charging current rate will be
halved
(safety mode, LED
"Charge" is flashing
). Any charging data being recorded hitherto will be kept in memory. Battery
charging is then interrupted, but the supply of possibly connected consumers will be continued by the unit, and the battery
is allowed to cool down. After that, automatic charging will be resumed. Also refer to:
"Lead batteries, 3 charging programs
, charging voltage rates and
temperature equalization"
from
page 8.
The unit recognizes automatically a missing sensor, cable break or short circuit of the sensor cables, as well as unreasonable
measuring values. In that case, it will switch automatically to the usual charging voltage rates of 20 °C / 25 °C being
recommended by the battery manufacturers.
