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

When the micro controller registers a
malfunction, the device will automatically
change to the alarm mode. The switching
sequence of the valve continues until the fault is
cleared (automatically or through maintenance).
The red LED fl ashes as long as the device is in
the alarm mode.
Malfunctioning could be caused by:
• Mistakes during installation
• Dropping below the necessary minimum
pressure
• Excessive condensate quantities
(overloading)
• Blocked/shut off outlet line
• Extreme amount of dirt particles
• Frozen piping
If the fault is not cleared within the fi rst minute,
a fault signal is triggered (see illustration) which
can be picked off as a potential-free signal via
the alarm relay. (24 Vdc version: pages 14-15)
