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.
The operating states of the BEKOMAT
21 are indicated by one LED with dif-
ferent flashing frequencies.

If the condensate discharge is not func-
tioning properly, the valve will keep
opening (about every 3 seconds) so as
to clear the fault automatically, if
possible.
Malfunction / Alarm

Test of valve function and

manual drainage: briefly press
button.
Additional feature of the BEKOMAT 21
PRO: press button for > 1 minute to
test the alarm function (s. below).
The BEKOMAT 21 PRO also has an
alarm-mode function:
If normal conditions have not been re-
stored after 1 minute, a fault signal
will be triggered:
• Alarm LED flashes.
• Alarm signal switches over (can be
transmitted via potential-free con-
tact).
• Valve opens every 4 minutes for a
period of 7.5 seconds.
Once the fault is cleared, the
BEKOMAT 21 PRO will automatically
switch back to the normal mode of
operation.
Malfunctioning could be caused
by, e.g.:
• Mistakes during installation
• Dropping below the necessary mi-
nimum pressure
• Excessive condensate quantities
(over-loading)
• Blocked/shut off outlet line
• Extreme amount of dirt particles
• Frozen piping
