1.
Setting
Press the button MODE while turning ON the battery charger by the general switch and release it once the YELLOW LEDS
are lighted. At this point only the YELLOW LED corresponding to position “0” remains lighted and both the RED LEDS “V” and
“A” start flashing: for 3 seconds in a slow way (1 flash each second) then for 5 seconds in a quick way (5 flashes each
second) and it continues like this in a cyclic way:
ADJUSTMENT MODE (
slow
flashing of the LEDS “V” and “A” (1Hz)
DATA STORAGE MODE (
quick
flashing of the LEDS “V” and “A” (5Hz)
2.
Adjustment
Entering ADJUSTING MODE: press the MODE button until the LED corresponding to the desired adjustment is
lighted. After 3 seconds from the button release You can enter the DATA STORAGE MODE.
3.
Data storage
Entering DATA STORAGE MODE: press the MODE button to memorize the desired adjustment. The automatic battery
charger’s start indicates data storage selection has been successful. After 5 seconds from the button release You return to
ADJUSTMENT MODE.
IMPORTANT:
by keeping the MODE button pressed for more 5 seconds while turning ON the device, it returns to the initial
“default” setting.
Alarms (Two-tone audible message)
An two-tone audible m flashing LED shows that an Alarm situation has occurred (in this case the battery charger stops
supplying current)

Battery Presence
Battery disconnected or not in conformity. (Verify the connection and the nominal
voltage).
Audible m YELLOW

Thermal Sensor
The thermal sensor is disconnected during the re-charge or it is out of working range.
(Verify the connection of the sensor and measure the temperature of the battery).
Audible m GREEN
flash
Timeout
Phase 1 and/or Phase 2 have a duration in excess of the maximal allowed. (Verify
the battery capacity).
Audible m RED-
YELLOW flash
Battery Current
Loss of output Current control. (Failure of the control logic).
Audible m RED-
GREEN flash
Battery Voltage
Loss of output Voltage control. (Battery disconnected or failure of the control logic).
Audible m YELLOW
-GREEN flash
Selection
An unavailable configuration has been selected (Verify the selector’s position)
Audible m RED-
YELLOW-GREEN flash
Thermal
Overheating of semiconductors. (Verify the fan operation).
Thermal Sensor and/or External Indicator
Thermal Sensor and/or External Indicator are Options that have to be connected to the 5 poles socket 180°.
Unless otherwise stated, the compensation of the Battery Voltage in function of the temperature of the Thermal Sensor
is of -5mV/°C for battery cell.
The control range of the Thermal Sensor goes from -20°C to +50°C.
Attention:
over +50°C charger goes in alarm and stops charge.
The External Indicator reflects exactly the LED Indicator which is placed on the equipment.
Further information can be found in the description of the Charging Curve.
