Function
BEKOMAT® 32U 11
9 Function
Via the inlet line (1) the condensate flows into the
BEKOMAT® 32U and accumulates in the housing (2).
A capacitively functioning sensor (3) continuously
registers the filling level and relays a signal to the
electronic control as soon as the container is filled.
The pilot valve (4) is activated and the membrane (5)
opens the outlet line to discharge the condensate (6).
When the BEKOMAT® 32U is empty, the outlet line
is reclosed tightly in time before unnecessary
compressed-air losses occur.

Function
12 BEKOMAT® 32U
At the BEKOMAT® 32U, two LEDs indicate the
individual operating states.
When applying supply voltage, the BEKOMAT® 32U
carries out a self-test.
Both LEDs are lit for approximately 1 second,
subsequently, the device changes over to the
"ready-to-operate" state.
Ready to operate, voltage is applied.
In the event that the condensate discharge is
disturbed, an alarm mode will start which is indicated
by the flashing of the red alarm LED.
Malfunction/alarm
Test of the valve function (manual drainage):
press and hold the button for approximately 2 s.
Test of the alarm function (see below):
press and hold the button for at least 1 min.
Do not use for permanent drainage.
Switching sequence of the valve in the alarm
mode
Alarm mode:
In the event that the BEKOMAT® is not empty after
one minute, a trouble indication is released:
• The alarm LED flashes.
• The alarm relay switches over
(the signal can be picked off potential-freely).
• The valve opens every four minutes for
7.5 seconds.
• When the malfunction has been eliminated,
the BEKOMAT® will switch back automatically
into the normal mode.
Possible trouble sources include:
• Mistakes during installation
• Dropping below the minimum pressure
• Excessive accumulation of condensate
(excess load)
• Blocked / obstructed outlet line
• Extreme amount of dirt particles
• Frozen pipework
Trouble indication via a potential-free contact

Function
BEKOMAT® 32U 13
The BEKOMAT® 32U releases a maintenance
message for a service that is to be carried out.
Depending on the operating mode, a visual
maintenance message (service) is activated
which signalises the replacement of the service unit.
The maintenance message is indicated by the flashing
supply voltage-LED "Power".
The maintenance message is released after
2 x 8.760 h or one million switching cycles.
The maintenance signal is released when
one of these two values is reached.
In the event of a power outage or when the energy
supply is deactivated, the status of the timer will be
maintained.
The activities to be carried out regarding maintenance
are described in the chapter entitled "Check and
maintenance".
Prior to the replacement of the service unit, a reset
needs to be carried out. The control unit is released
by actuating the arresting hook. When removed, the
TEST button must be pressed and held for at least
five seconds.
