Pilot Lamps:
"Batt. Full"
(BOARD battery fully charged,
green
)**:
On:
Battery has been charged to 100 %, trickle charge U2, finished.
Flashing:
Main charging process is active in the charging phase U1, indication of the charging state of
75 % (lead), approx. 90 % (LiFePO4) (short flashing), gradual increase to 100 % (long flashing).
Off:
Main charging process is still in the phase I.
"Power"
(Main charging BOARD battery,
yellow
)**:
On:
Charging converter operates, the BOARD battery is controlled and charged.
Flashing:
Battery Protection: Battery overtemperature > 50 °C, switchover to low safe charging voltage
and half of the max. charging current. Automatic return, as soon as the temperature is 2 °C
less.
Turns off shortly
every 2 s:
1. The power control of the charging converter has reduced the output capacity by more
than 30 % (STARTER battery discharge protection), since the voltage of the STARTER
battery dropped below the value for "Reduction of the charging capacity". The charging
capacity will be increased automatically, as soon as the voltage exceeds the value for
"increase of the charging capacity".
2. Only LiFePO4: Battery temperature below 0 °C. The charging current is reduced for all
modes of charging to protect the battery. If the battery is discharged, charging times will
increase.
Off:
Charging converter in idle mode.
** "Batt. Full"
and
"Power"
are flashing simultaneously:
The battery temperature sensor is not connected with charging program LiFePO4!
Function of the Power Control at STARTER Battery and Generator:
The charging converter is either voltage-controlled or via the control input "D+". It will be deactivated automatically if the
engine is switched off. It starts with minimum charging capacity.
After the engine starts, the STARTER battery will begin charging immediately and its starting capacity will be maintained.
Therefore, the charging converter does not start charging the BOARD battery, before the voltage value "increase of the
charging capacity" of the starter battery is reached.
The unit gradually increases the charging current of the BOARD battery as the STARTER battery’s voltage exceeds the
“increase of the charging capacity” threshold.
In case of a heavy load on the starter circuit due to many large loads, and the STARTER battery’s voltage drops again below
the value "reduction of the charging capacity", such as during engine idling, there will be a gradual reduction of the
charging current for the BOARD battery to relieve the starter circuit.
If the voltage drops below the "Switching off threshold" for 30 seconds, the charging converter will be switched off
automatically. As soon as the voltage exceeds the threshold "increase of the charging capacity", the converter will be
switched on, and the capacity will be increased gradually until the required (maximum) charging capacity is reached.
A reduction of the charging current by more than 30 % due to insufficient input voltage of the generator will be indicated
by the LED "Power", which turns off shortly every 2 seconds. The LED will again light permanently, as soon as either the
input voltage is sufficient or the power requirement has dropped due to a charged BOARD battery.
The charging converter simulates a large load at the generator/starter circuit to ensure an activation also with Euro 6
vehicles with intelligent generators, if required.
Recharging Branch for STARTER Battery 12 V:
The unit is equipped with a charging branch, which ensures support charging and trickle charging of the STARTER battery
12 V in case of extended standstill periods. It will be activated automatically, as soon as the BOARD battery has been
sufficiently charged, for instance by a mains supply charger (see Technical Data "Recharging Branch"). A small part of the
charger current (approx. 0 - 1 A) is diverted from the BOARD battery to the STARTER battery.
Charging voltage and charging current are reduced to prevent the STARTER battery from being overcharged.
Activation of the recharging branch is only possible with control "D+" of the charging converter, and not with "voltage
control", described under
"D+"
Control Input, page 8 !
A possible use of the recharging branch is detailed in the different connection plans.
