2.3.1. Alarm mode
The BEKOMAT
is continuously monitored by electronic and sensory devices. If a fault or malfunction occurs, the BEKOMAT
®
is automatically switched to alarm mode (e.g. due to blocked condensate discharge, or overload). In alarm mode, the solenoid
valve is automatically opened, starting in cycle mode in order to eliminate the problem. If the problem persists for more than one
minute, the red alarm LED flashes and the optocoupler output is switched. The valve is then repeatedly opened every four minutes
for 7.5 seconds, until the problem is resolved automatically or by servicing the device. After the problem has been resolved, the
BEKOMAT
automatically switches to normal operating mode.

The condensate enters the container (1) through the
condensate inlet.
The container can be filled to the limit, as the pressure is
equalised through the venting line (2).
The capacitive dual sensor (3) constantly monitors the
filling level in the container.
As soon as the container is full, the sensor sends a
signal to the electric control (4). The electric control
actuates the solenoid valve (5), and a large outlet
diaphragm is opened to allow the condensate to be
discharged.
While the container is under system pressure (min.
0.5 bar), all condensate in the container is drained off
through the condensate drain (6).
The sensor measures the discharge rate, which is used
to control the maximum valve opening time.
Should the condensate fail to drain off, the valve is closed
after 2.5 seconds and automatically opened again after 2
seconds. This procedure is repeated for 1 minute
as the control system tries to resolve the problem.
