Air is blown into the battery through a capillary tube specifically provided for this purpose.
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.

Temperature-
controlled char-
ging option Used for batteries with fixed electrolytes (gel, sealant), or for batteries in use in extreme
temperatures. The charging voltage is adapted depending on the battery temperature to
achieve faster or more gentle charging.
Important! Connect temperature sensor to the correct poles and connect to the negati-
ve pole on the battery.

The Aquamatic option incorporates
automatic actuation of a solenoid valve to
fill the battery with water automatically.
The charging over option is used to
activate a signal lamp. When charging is
complete, the normally open contact
closes automatically.
The collective fault option can be used to
activate a signal lamp.
The NO contact closes automatically
whenever a fault (ERROR) is detected.
