NOTE!
Danger due to non-compliance with the permissible mains voltage tolerance.
Malfunctions and damage to property may result.
▶
The electrolyte circulation option has an air pump integrated into the battery charger.
This delivers air into the battery via specially designed capillary tubes. This results in an
intensive mixing of the electrolyte. The benefit is less battery heating, a longer battery life
and less water loss during charging.
If an error is detected due to a pump defect - or due to leaks in the connection to the
battery - the status code "Statecode 14" appears on the display. This defect can be indic-
ated as a common error by means of an external signal lamp, for example.
The sequential control of the electrolyte circulation takes place via the battery charger
control unit. Several selection options are available in the configuration menu for this pur-
pose. Detailed information can be found in the "Additional functions" section of the "Dis-
play" chapter.
These selection options include the factory default programs 1 through 5. The relevant
parameters for these programs are shown in the table below, followed by an explanation.

In each of these programs, the solenoid valve picks up for an "ON 1" time and drops out
for an "OFF 1" time. This process repeats as many times as specified for "Repeat". After
this number of repetitions has elapsed, the "ON 2" and "OFF 2" times continue until the
end of charging.
Cleaning the air filter insert
Clean the air filter insert for the integrated air pump once a year. If there is a lot of dust,
shorten the cleaning interval accordingly. It is necessary to remove the air filter insert (2)
for cleaning purposes. Remove the air filter (1) by pulling it off and then reinstall it as fol-
lows:

For the electrolyte circulation option, a limited mains voltage tolerance of 207 V to
250 V, phase-phase, applies compared to the battery charger: 360 V to 433 V.
