12 Product Overview
Monitoring
The inlet pressure and the nozzle pressure are monitored with the analogue pressure sensors "PS4" and
"PS5". On systems type B without booster pump and without optional sterile filter the nozzle pressure
is equal to the inlet pressure, thus the pressure sensor "PS5" is not present.
The pressure after the optional sterile filter is monitored with the pressure switch "PS2" on systems type
A (with booster pump), and on systems type B (without booster pump) with the pressure sensor "PS5"
since the pressure after the sterile filter is equal to the nozzle pressure.
The conductivity of the fully demineralized water is continuously monitored. If the conductivity of the
fully demineralized water exceeds the admissible range (max. 15 µS/cm), the drain valve Y10 on the
valve manifold (25) opens and the water system is flushed until the conductivity meets the preset value.
An error message is displayed or the system is stopped if the conductivity value does not reach the
admissible range within a certain period (conductivity >100 µS/cm).
Hygiene function/Flushing
To prevent standing water, each spray circuit which is not active is emptied via the corresponding spray
valve (the spray valves are connected to the drain in currentless status).
After 1 hour without humidification, the flushing valve opens to empty the system.
If the conductivity in the water supply line exceeds a preset value or if the humidification system has
been without demand for more than 23 hours, the drain valve Y10 opens and the water supply line and
the water lines in the central unit are flushed for a certain time with fresh RO water. During the flushing
additionally residual water in the spray circuits is sucked out via the built-in water jet pump (26) and is
led via the open funnel with trap (27) to the wastewater line of the building.
