The condensate flows through the feed
line (1) into the BEKOMAT unit and
accumulates in the container (2). A
capacitive sensor (3) continuously re-
gisters the liquid level and passes a
signal to the electronic 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 BEKOMAT unit has been
emptied, the outlet line is closed
again quickly and tightly without wa-
sting compressed air.

> 1 min Alarm mode
When the microcontroller registers a
malfunction, the device will automati-
cally change to the alarm mode. The
switching sequence of the valve (see
illustration) continues until the fault is
cleared (automatically 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
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
first minute, a fault signal is triggered
(see illustration) which can be picked
off as a potential-free signal via the alarm
relay.
