Fronius Selectiva 4.0 2100 Operating Instructions Manual page 57

NOTE!
Danger due to non-compliance with the permissible mains voltage tolerance.
Malfunctions and damage to property may result.
▶
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.
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 indicated as a common error by means of an external signal lamp, for ex-
ample.
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 purpose. Detailed information can be found in the "Additional
functions" section of the "Display" 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.
Program ON 1
1 30 min
2 3 min
3 3 min
4 5 min
5 2.5 min
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 follows:
OFF 1 Repeat
