Safety In order to connect optional components it may be necessary to open the housing. The fol-
lowing warning notices must be obeyed:
Electrolyte circu-
lation The electrolyte circulation option features an air pump integrated in the battery charging
system. 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 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 battery charging system's control sys-
tem. A number of selection options are available for this purpose in the configuration menu.
More information can be found under "Additional functions" in the "Display" 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 together with a subsequent ex-
planation.
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 process continues with the "ON 2" and
"OFF 2" times until charging is completed.
WARNING! An electric shock can be fatal. The housing may only be opened by
a service engineer who has been trained by the manufacturer. The device must
be disconnected from the mains before starting any work with the housing
opened. A suitable measuring instrument must be used to ensure that electrically-
charged components (e.g. capacitors) are fully discharged. Use an easily legible
and understandable warning sign to ensure that the charger is not reconnected
to the mains supply before all the work has been completed.
WARNING! Work that is carried out improperly can cause serious injury or dam-
age. All work involved with connecting optional components must only be carried
out by qualified specialist technicians. If there are installation instructions or a
leaflet for the optional component concerned, then all warning notices and in-
structions therein must be obeyed.
NOTE! Risk of damage to air pump from the ingress of electrolyte from the battery
or from operation without any back pressure. Always set up the battery charging
system at least 0.5 m (1 ft. 7.69 in.) above the battery to be charged. Always use
an undamaged, purpose-supplied connecting hose to connect the compressed
air outlet on the battery charging system to the battery.
