TECHNICAL FEATURES OF THE CBHF1-SM SERIES (Robot FR3xx/FR4xx)
The innovative characteristics of the CBHF1-SM range of 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 finished 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. Efficiency > 85%.
12. Output ripple at maximum charge lower than 100mV.
13. Start of the charge cycle also with 2V batteries.
14. Thermal protection against over heating.
15. 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.
OPERATING PRINCIPLE
On switching on a new battery charger of the CBHF1-SM series, programmation data are displayed (these
parameters depend on internal dipswitch configuration).
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
configuration (see tables on page n. 4):
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 first 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 galvanically the battery from the battery charger.

Technical remarks
When the maximum voltage admissible for a specific 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.
On the next page we have written the meaning of dipswitch. Through the set of 8 dipswitches it is possible to
change the charging curve (16 charging curves are available for Wet and Gel batteries and it is possible to
customize the charging profile under the specifications of battery manufacturers), the battery voltage (12V or
24V) and the charging current (4A or 8A or 10A or 12A). The set of 8 dipswitch is easy to find (is located
under the front label of the charger, lifting the corner on the bottom-left) without opening the charger.

The occurred problem
Charge the battery for 8 hours and after a few pallet the battery charger show orange led.
Possible remedies
Attention: if the tension was interrupted during 8 hours of charging then when re-start the
tension, the battery charger start again from zero.
1. Check all the connection (battery-battery charger);
2. Check the “Dip Switch Configuration”;
3. Discharger completely the battery;
4. Charger again the battery for 8-10 hours (finally shows=green led);
5. After have charger completely the battery, don’t keep away the plug of the tension and
touch the button ”S” on the battery charger (reads and writes the values A, U, h, C, E);
6. Check with the tension meter the voltage of the two batteries, max voltage must be 27
Volt;
The tension between the two batteries must be the same, if isn’t so, the battery that has
less voltage has a part in “short-circuit”.
Should the problem persist, contact the Customer After-Sales Service of Manufacturer.
