Ventilation fault
Fault
Low pressure in the ventilation
system, error in the pump or in
the electrolyte circulation system.
If the pressure values are not
corrected again within one minute,
the charging current I1 is reduced
to 80% in the main charging
phase and the pump is no longer
switched on.
Low pressure in the ventilation
system, error in the pump or in
the electrolyte circulation system.
If the pressure values are not
corrected again within one minute,
the charging current I1 is reduced
to 80% in the main charging
phase and the pump is no longer
switched on.
More than 5 malfunctions in the
electrolyte circulation system
(pressure either too high or too
low) during the charging cycle;
the loading current I1 is reduced
to 80% in the main charging
phase and the pump is no longer
switched on.
Leaky point in the electrolyte
circulation system; after switching
off the pump, the pressure drops
rapidly.
Blockage of the charging device
due to malfunctions in the electro-
lyte circulation system.

Elimination
• Check the electrolyte circulation system
and the pump
• Check the electrolyte circulation system
• Check the electrolyte circulation system
and the pump
• Check the electrolyte circulation system
and the pump
• Check the ventilation pipelines and pump
• Charging device must be unlocked by the
service technician
