Air is blown into the battery through a capillary tube specifically provided for this purpo-
se.
This allows intensive mixing of the electrolyte to take place.

The benefit is reduced heating of the battery (longer service life) and reduced water
loss during charging.

Cycle control
The electrolyte circulation cycle is controlled by predefined programs.

Additional option, ERROR 14 error output:
Error detection (air pressure monitoring) is optionally available for electrolyte circulation.
The charger multifunction panel displays an error message („Error 14“) if electrolyte
circulation fails.

Important! If the electrolyte circulation pump does not have an optional error output:
-

Connect contacts X6/1 and X6/4 together.

If electrolyte circulation pump does have an optional error output:
-

Connect no-voltage contact (relay/normally open contact) to contacts X 6/1 and X 6/4

Changing charge parameters: If electrolyte circulation fails, the charger only ensures
sufficient circulation of the electrolyte.
