LED Indicator
RED LED shows that the battery is in the initial charging phase.
YELLOW LED shows that the battery charger has reached 80% of charge.
GREEN LED shows that the battery has reached 100% of charge.
Further information can be found in the description of the Charging Curve.
Example
: RED LED on with brief blinks indicates a constant tension phase.
Alarms (Two-tone audible message)
An two-tone audible message and the flashing LED shows that an Alarm situation has occurred:
Condition
Alarm Type
Description (Action)
Audible m
RED flash
Battery Presence Battery disconnected or not in conformity. (Verify the
connection and the nominal voltage).
Audible m
YELLOW flash
Thermal Sensor
The thermal sensor is disconnected during the re-
charge or it is out 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

flash
Thermal
Overheating of semiconductors. (Verify the fan
operation).
When there is an alarm the battery charger stops supplying current.
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.
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.
