Description
Barrier M
3.
Controller The Barrier M controller can be installed in a sheet steel or stain-
less steel control cabinet. The settings and important system data
are displayed on the operating panel. Status and error messages
are also indicated by LEDs on the operating panel.
UV sensor The UV sensor constantly monitors the intensity of the UV light in
the chamber and displays its status on the control cabinet opera-
ting panel.
Disinfection control Depending on the SAtC (Spectral Attenuation Coefficient) or water
transmittance, the flow rate, deposits on the quartz sleeves or UV
measuring window and the age of the UV lamps the UV power of
the lamps can be automatically stepless adjusted.
Dose control The dose control determines the UV dose currently present in the
chamber, which means the lamp power is adapted to the prevailing
conditions accordingly.
Flow rate monitoring The flow rate monitoring enables processing of the signals of a
flow rate measurement system integrated at the customer site and
the triggering of an alarm via minimum and maximum limit values.
Automatic
cleaning mechanism
The automatic cleaning mechanism, available as an option (for the
Barrier M 80 or higher) is controlled by programmed time intervals.
It is also activated automatically if the intensity of the UV light in the
chamber drops, just before the minimum UV intensity is reached.
Manual
cleaning mechanism
The mechanical cleaning mechanism, also available as an option,
can be actuated as required without having to switch off the UV
disinfection unit.
