Automatic mode:
switching off the
energy cell
The energy cell is completely switched off after an automatic switch-off or when the
keylock switch has been turned to the - O - position.
Once the energy cell has been completely switched off, it is in the „safe state“. This
means that all valves for the hydrogen supply that can be activated by the energy cell
are closed.
The electrical connection to the connected battery is also disconnected.
To allow fully automatic operation, a start can be triggered with an external start signal
on pins 4 and 5 of input X4, even in the safe state and even if the keylock switch is in
the - O - position.
„1“: In phase 1, the charging current
remains at a constantly high level to
ensure that charging is as fast as
possible.
„2“: In phase 2, the ability of the batteries
to absorb energy decreases. The
charging current is reduced before
outgassing starts at the edges of the
electrode plates. The charging
voltage remains constant. Now even
the lower layers of the electrode
plates are gradually converted.
