The innovative characteristics of the CBHF2-D 24V 25A/30A battery charger are the following:
1.
Advanced Mosfet technology with high frequency and insulation transformer.
2.
Charging process fully controlled by microprocessor.
3.
Visualization on a lit display of the charging current, of the battery voltage, of the charging time, of the electric charge supplied in Ah's and of the
electric energy absorbed in KWh's.
4.
Possibility to change the charging curve by means of microswitches (DIP-switches), choosing from 16 standard pre-programmed curves for lead-acid,
Gel and VRLA batteries. Any other optional curve available on request.
5.
Possibility to change the battery voltage and the charging current by means of the relevant microswitches.
6.
Charging process starting in the "soft start" mode, storing of the data of the cycle just fi nished and automatic reset upon connection of a new battery.
7.
Protection against polarity inversions, short-circuits, over-voltages or anomalies by means of an output relay.
8.
Battery to battery charger connection without sparks on the output terminals with obvious advantages for the active safety, thanks to the recognition
of the battery voltage downstream the normally opened output relay.
9.
Alphanumeric signals of possible anomalies.
10. Insensitive charge parameters in case of ±10% network voltage
11. Effi ciency > 85%.
12. Output ripple at maximum charge lower than 150mV.
13. Compensation of the voltage drop on the connecting cables to the battery with algorithm inside the microprocessor.
14. Start of the charge cycle also with 1V batteries.
15. Thermal protection against over heating.
16. An auxiliary relay that permits the partial or total disconnection of an electric traction machine is available in should the batteries have to be re-
charged with the battery charger placed on board the machine. In this way the relay prevents the machine from starting while the battery charger is
operating. This is a safety device.
On switching on the CBHF2-D 24V 25A/30A battery charger, programmation data are displayed (these parameters depend on internal dipswitch confi guration).
After the "SPE" logo you can see on display the version of software installed on the machine. At this time the following programmed parameters are displayed
on sequence according to internal dipswitch confi guration (see tables on page n. 56):
battery voltage, charging current, number of charging curve and is displayed the message "GEL" if programmed charging curve is suitable for gel batteries or
"Acd" if programmed charging curve is suitable for Lead-Acid (Wet) batteries. After these operations the charger is ready to check the battery voltage and to
decide whether to start the charging process. If the battery is not connected to the battery charger, the message 'bat' will be displayed. The same message is
displayed also in case of negative result of the testing (for example, reversed polarity or battery having a wrong voltage). If the result of the testing is positive,
the value of the battery voltage is displayed for about 5 seconds, with output relay open. After 5 seconds the charging of the battery can start. The output relay
closes and the current of the fi rst phase rises slowly till it reaches the nominal value programmed.
If the user disconnects the battery from the battery charger during the charging process, after a few seconds the battery charger will re-initialize and prepare
to start a new charging process.
The display always shows the charging current of the battery. The battery voltage, the time since the beginning of the charge, the charge yielded in Ah's and the
energy consumed in KWh can be seen only by pressing the button S.
The progress of the charging process is shown by three LED's: red, yellow and green, as in the whole range of the battery chargers.
The green LED indicates the stop of the charging or the last phase in case of deep charging process; in the former case, the relay is opened to disconnect galva-
nically the battery from the battery charger.
•
When the maximum voltage admissible for a specifi c battery is reached (value given by the manufacturer) the error message 'E01' is displayed, and
the process is terminated.
•
By using an internal thermostat, the charging can be interrupted in case of excessive battery charger over-temperature. In this case the error message
'E02' is displayed.
•
Possibility of setting each single charging phase. On exceeding this time, the charge will be interrupted and the error message 'E03' will be displayed.
•
The display of the message 'SCt' indicates safety timer operation.
•
The message 'Srt' will be displayed in case of internal short circuit.
Authorized Service Centers can change the battery voltage and the charging current always by means of a DIP-switch. On the control card placed behind the
front panel of the battery charger eight DIP- switches are available for:
1.
Selecting the charging curve: DIP1 DIP2 DIP3 DIP4.
2.
Selecting the fast charging current I1 (current of the fi rst charging phase): DIP5 DIP6
3.
Selecting the battery voltage: DIP7 DIP8.
Programming of battery charger is possible by changing dipswitch confi guration. According to the charging curve, charging current and battery voltage reque-
sted, it is necessary to set the position of each dipswitch either in the "ON" or the "OFF" position in compliance with the selection scheme shown at the following
page. The set of 8 dipswitch is located under the front label of the charger, lifting the corner on the upper-left) without opening the charger.
