Note:
If two or several batteries are connected in parallel to the charging port "+Board I", set the total capacity
(total Ah-value of the connected units)!
According to the battery manufacturers,
permanent
parallel operation is admissible in case of two or
several batteries of the same type, the same capacity, as well as of the same age (history) in cross
connection.
The above mentioned capacity rates should be considered as approximate values regarding battery load
and charging time.
3.)
Activation of the Battery pulser
(only possible with lead batteries):
If the vehicle is not used for an extended period and it is parked in a hall (no solar power), the idle mode at a socket
is recommended, since the battery board I, as well as the battery Start II will be kept charged.
If neither mains supply nor solar power is available, the pulser can be used for lead-acid, gel, AGM batteries.
It trains the battery Board I with short, but quite powerful current pulses, which shall counteract creeping
sulphation. Nevertheless, the average current consumption is still low. The pulser will be activated automatically, if
there is no charging source and the switch is in position "Pulser".
Automatic disconnection of the pulser in case of voltage at terminal "Board I":
< 12.00 V
With switch position
"off"
or always when the characteristic line of charging
LiFePO4
had been set, the
pulser will
not be active.
4.)
How to activate the charging lock input "Sw"
(only active with LiFePO4 batteries):
The BMS (Battery Management System) of the LiFePO4 battery is able to stop the charging process (mains, B2B or
solar) at any time by means of the input "Sw", when the battery is full, the battery temperature is too high or too
low, or the voltage is too high. If required, also a reactivation is possible.
For this, the output charging stop/warning/error of the LiFePO4 battery must be connected to the control input
terminal "Sw". This switch can be used to select the type of disconnection signal coming from the BMS:
Left Switch
Sw
: A signal 0 V switches the charger to safety voltage 12.8 V (charging stop)
Right Switch
Sw
: A signal 12 V switches the charger to safety voltage 12.8 V (charging stop)
The charger will not be switched-off completely. If required, it can supply a voltage rate of 12.8 V to the consumers
and the battery, or it can support them to avoid total discharge of the battery.
If the input
terminal "Sw"
is
not used
, position the switch to
right "Sw".
