Via the inlet line (1) the condensate flows into the
ENL 5 Vario and accumulates in the housing
(2).
A capacitive functioning sensor () continuously registers
the filling level.
As soon as the condensate has reached a certain
level, a fixed waiting time starts.
During this period, further condensate flows in and
continues filling the ENL 5 Vario
ENL 5 Vario and upstream units must be adjusted to
each other.
After the waiting time has expired, the condensate
may have risen up to the inlet area (1). The solenoid
valve (4) is switched over now and the zone above the
valve membrane is vented.
The valve membrane (5) lifts off from the valve seat,
the overpressure in the housing forces the condensate
into the outlet line (6).
The total amount of accumulated condensate is discharged.
When the sensor () is “free”, meaning that the total
amount is discharged, the solenoid valve re-switches
and the valve membrane is re-closed tightly through
the overpressure which builds up above the latter
membrane.
A new cycle starts with the inflow of condensate (1).
