11.3. Battery charger
This platform stairlift includes a charger as standard, which has a charging voltage of 24 volts
and a charging current of 2A.
The input voltage can be in a wide range starting from 90V up to 264V. A frequency of 47 Hz
to 63 Hz is supported. These wide ranges mean that the charger can be used in almost any
country.
11.3.1. Operating states of the charger
• LED orange (cf. Figure 9, Pos. 1):
The batteries are charged constantly with 2A until the batteries have reached the
charging voltage.
• LED green (cf. Figure 9, Pos. 1):
The charger keeps the battery voltage at 27.6 V and slowly reduces the charging
current. The charger can now remain connected indefinitely without damaging the
batteries. If the voltage drops below 27.6 V, the charging process starts again and the
LED changes colour to orange.
If the charger does not detect a battery, the LED also lights up green.
