The condensate flows through the feed
line (1) into the ENL unit and accumulates
in the container (2). A capacitive sensor
(3) continuously registers the liquid level
and passes a signal to the electronic
4
control as soon as the container is filled.
The pilot valve (4) is then activated and
the diaphragm (5) opens the outlet line
(6) for discharging the condensate.
When the ENL unit has been emptied,
the outlet line is closed again quickly and
tightly without wasting compressed air.

When the microcontroller registers a
malfunction, the device will automatically
change to the alarm mode. The switching
sequence of the valve (see illustration)
continues until the fault is cleared (auto-
matically or through maintenance). The
red LED flashes as long as the device
is in the alarm mode.
Malfunctioning could be caused by, e.g.:
• Mistakes during installation
• Dropping below the necessary mini-
mum pressure
• Excessive condensate quantities (over-
loading)
• Blocked/shut off outlet line
• Extreme amount of dirt particles
• Frozen piping
If the fault is not cleared within the first
minute, a fault signal is triggered (see
illustration) which can be picked off as a
potential-free signal via the alarm relay.
