Term. Signal Description
5 Ventilation_Feedback
(Ventilation_FB)
Ventilation feedback
If the vehicle indicates by signalling "State D" that a ventilation is
required for charging, the switch output for the ventilation will be
enabled. The charging contactor will be closed, but opened again
after 10 seconds, if this feedback input remains disabled. When
using ventilation, this input must be enabled by a ventilation
monitoring, if the ventilation operates properly.
