NOTE!
Danger due to non-observance of the permissible mains voltage tolerance.
This can cause malfunctions and damage.
▶
For the electrolyte circulation option, a restricted mains voltage tolerance of
207 V to 250 V, phase-phase: 360 V to 433 V, applies for the charger.
The electrolyte circulation option features an air pump integrated in the charger.
This introduces air into the battery through capillary tubes that are provided spe-
cifically for this purpose. This allows intensive mixing of the electrolyte to take
place. The benefit is the reduced heating of the battery, and consequently longer
battery-life, plus reduced water loss during charging.
If a pump fault or leaks in the connection with the battery result in a fault being
detected, then the status code "Statecode 14" will appear on the display. One
way in which this fault can be indicated is by using an external indicator lamp to
show a common error.
The electrolyte circulation cycle is controlled by the charger's control system. A
number of selection options are available in the configuration menu for this pur-
pose. More information can be found under "Additional functions" in the "Dis-
play" section.
The default preconfigured programs 1 to 5 are among these selection options.
The relevant parameters for these programs are listed in the table below togeth-
er with a subsequent explanation.
Program ON 1 OFF 1 Repeat ON 2 OFF 2
1 30 min 25 min 1 x 5 min 25 min
2 3 min 10 min 4 x 3 min 20 min
3 3 min 12 min 1 x 3 min 12 min
4 5 min 10 min 3 x 5 min 20 min
5 2.5 min 7.5 min 1 x 2.5 min 7.5 min
In each of these programs, the solenoid valve opens for a time "ON 1" and closes
for a time "OFF 1". This process is repeated for the number of times specified
under "Repeat". After this number of repetitions has been completed, the pro-
cess continues with the "ON 2" and "OFF 2" times until charging is completed.
Cleaning the air filter insert
The air filter insert for the integrated air pump should be cleaned once a year. In
dusty environments, the cleaning interval should be shortened accordingly. The
air filter insert (2) must be removed for cleaning. Remove the air filter (1) by
pulling it out and then refit it as follows:
