Battery Care
The Battery Care philosophy is base on algorithms that implement rapid and automatic charging, battery charge
optimization during time, flat batteries recovery and real time diagnostic during installation and operation. The Real
Time Auto-diagnostic system, monitoring battery faults such as, elements in short circuit, accidental reverse polarity
connection, disconnection of the battery, they can easily be detected and removed by help of Blink Code of Diagnosis
Led; during the installation and after sell. Each device is suited for all battery types, by means of jumpers it is possible
setting predefined curves for Open Lead Acid, Sealed Lead Acid, Gel, Ni-Cd and Li-Ion.They guarantees battery
reliability in time by continuously testing the internal impedance status, avoids any possible risk of damages and
grants also a permanent, reliable and safe connection of the battery to the power supply. The system, through a
battery stimulation circuit with algorithms of evaluation of the detected parameter, is able to recognize sulphated
batteries or batteries with a short-circuited element.
Battery Test: Automatic. Every 60 sec. check battery connection. Every 220 minute in Float charge, make the test of
the battery efficiency. The fault is signalized with relay commutation and diagnosis led blinking.
Check for accidental disconnection of the battery cables:
All In One detects accidental disconnection and immediately switched off the output power.
Battery not connected:
If the battery is not connected no output power.
Test of quality wire connections:
During Float charge the quality (resistance) on the battery connection is checked every 60 sec. This to detect if the
cable connection has been properly made.
Battery in Open Circuit or Sulphated:
Every 220 minute. The CB tests of internal impedance, in Float charging mode.
Reverse Polarity check:
If the battery it is connected with inverted polarity, CBis automatically protected.
Test of battery voltage connections:
Appropriate voltage check, to prevent connection of wrong battery types, more or less than the nominal voltage.
End of Charge check
When the battery it is completely full, the device automatically switch in Float charging mode.
Check for Battery Cells in short circuit
Thanks to specific algorithms of evaluation, the CBs recognize batteries with cells in internal short circuit.
In Float charge every 220 minute test of element in short circuit.
Diagnosis of battery and device
All CB devices support the user during installation and operation. A Blink code of Diagnosis Led allows to
discriminate among various possible faults.
Error conditions, "LED Battery Fault" ON and "LED Diagnosis" blinking with sequence; see Display Signal section.
Protection Features
On the primary side: the device is equipped whit an internally fuse. If the internal fuse is activated, it is most
probable that there is a fault in the device. If happen, the device must be checked in the factory.
On the secondary side Battery and load: The device is electrically protected against short circuits and overload.
Inversion polarity: the module it is automatically protected against inversion of battery polarity and connection of
load inverted.
Over current and output short circuit: the unit limits the output current (see the technical data).
Deep discharge: not possible. The unit disconnects the battery when a minimum voltage level is reached.
Thermal behaviour
Surrounding air temperature 50°C. For ambient temperature of over 50°C, the output current must be reduced by
2.5% per °C. Max 70°C At the temperature of 70°C the output current will be 50% of In. The equipment does not
switch off in case of ambient temperature above 70°C or thermal overload. The devices are protected for Over
temperature conditions "worst case"; in this situations the device Shut-down the output and automatic restart when
temperature inside fall.
Charging Curve
Automatic multi-stage operation and real time diagnostic allows fast recharge and recovery of deep discharged
batteries, adding value and reliability to the system hosting the CB device. The type of charging is Voltages
stabilized and Current stabilized IUoUo. Five charging phases are identified by a flashing code on a Diagnosis LED.
To maintain the Output Load in lower Voltage state, don't put jumper in position 6, in this case no boost charge but
