Alarm mode
Compared with BEKOMAT standard
types, the alarm mode of the BEKOMAT
4 CV is different. By an altered opening
sequence on alarm, a significantly larger
condensate quantity may be discharged,
this enabling the reduction of a conden-
sate backup during the state of alarm.
When the microcontroller registers a
malfunction, the device will automatically
change to the alarm mode. The switching
sequence of the valve (see illustration)
continues until the fault is cleared (auto-
matically 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 mini-
mum 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.
