6.2 Functional Description
The Aquamatik water replenishment system is used to adjust the rated electrolyte
level automatically on traction batteries for industrial trucks.
The battery cells are interconnected through hoses and are attached to the water
supply (e.g. water container) through a plug connection. When the shut-off cock is
opened all the cells are filled with water. The Aquamatik plug controls the amount of
water required and, at the relevant water pressures, ensures the water supply is shut
off and the valve is closed securely.
The plug systems have an optical level indicator, a diagnostic port to measure the
temperature and electrolyte density and a degassing port.
6.3 Adding water
Water should be added to the batteries just before the battery is fully charged. This
ensures that the amount of water added is mixed with the electrolyte.
6.4 Water pressure
The water replenishment system must be operated with a water pressure in the
water line of 0.3 bar - 1.8 bar. Any deviations from the permissible pressure ranges
will affect the operation of the systems.
Water drop
Assembly height above battery surface is between 3 - 18 m.
1 m corresponds to 0.1 bar.
Pressure water
The pressure regulating valve is adjusted to suit the system and must lie between
0.3 - 1.8 bar.
