Procedure
The AC input current limit can be set using DIP switches ds8, ds7 and ds6 (default
setting: 30A, automatically limited to 16A in 16A models).
Procedure: set the DIP switches to the required value:
ds8 ds7 ds6

Remark:
Manufacturer-specified continuous power ratings for small
generators are sometimes inclined to be rather optimistic. In that
case, the current limit should be set to a much lower value than
would otherwise be required on the basis of manufacturer-specified
data.
5.5.1.2 AES (Automatic Economy Switch)

off = AES off
on = AES on
5.5.1.3 Charging current limitation (default setting 75%)
For maximum battery life, a charging current of 10% to 20% of the capacity in Ah
should be applied.
Example: optimal charging current of a 24V/500Ah battery bank: 50A to 100A.
The temperature sensor supplied automatically adjusts the charging voltage to the
battery temperature.
If faster charging – and a subsequent higher current – is required:
- The temperature sensor supplied should always be fitted, since fast charging can
lead to a considerable temperature rise of the battery bank. The charging voltage will
be adapted to the higher temperature (i.e. lowered) by means of the temperature
sensor.
- The bulk charging time will sometimes be so short that a fixed absorption time would
be more satisfactory ('fixed' absorption time, see ds5, step 2).
Procedure
The battery charging current can be set in four steps, using DIP switches ds4 and ds3
(default setting: 75%).
