The condensate flows through the feed
line (1) into the BEKOMAT unit and ac-
cumulates in the container (2). A capaci-
tive sensor (3) continuously registers the
liquid level and passes a signal to the
electronic control as soon as the con-
tainer 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 wasting com-
pressed air.
The operating states of the BEKOMAT 20
are indicated by one LED with different
flashing frequencies.

Discharge procedure
Outlet line open
If the condensate discharge is not func-
tioning properly, the valve will keep open-
ing (about every 3 seconds) so as to clear
the fault automatically, if possible.

drainage: briefly press button.
Additional feature of the BEKOMAT 20
FM: press button for > 1 minute to test
the alarm function (s. below).
The BEKOMAT 20 FM also has an
alarmmode function for condensate
drain
If the sensor will not be free after 1
minute, a fault signal will be triggered:
• Alarm LED flashes.
• Alarm signal switches over (can be
transmitted via potential-free contact).
• Valve opens every 4 minutes for a period
of 7.5 seconds.
Once the fault is cleared, the BEKOMAT
20 FM will automatically switch back to
the normal mode of operation.
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
