Figure 6: Display of the SynPur
The SynPur is ready for operation when the supply voltage and the water supply
(with adequate water pressure) and the additive (with adequate gas pressure) are
connected. In addition, the lighted mains switch indicates that the device is turned
on.
The infeed pressure switch monitors the pressure of the water supply and shuts
the system off if the water supply malfunctions. In this case, the red LED „Fault“
lights up on the display.
Another pressure switch monitors the gas inflow. The LED „Additive“ lights up on
the display when gas is present. If the gas supply malfunctions the pressure switch
shuts the system off and the red LED „Fault“ lights up on the display. At the same
time, the LED „Additive“ turns off. Operation can be resumed after the bottle has
been replaced (for more information on replacing the bottle, see Section 6.3).
Because the resins in the synthesizer cartridges are depleted during the process of
extracting the minerals, the SynPur continuously monitors the quality of the
demineralized water. When a first threshold value is reached, the SynPur outputs a
service message indicating that the synthesizer cartridge should be replaced soon.
When the second threshold value is reached, the SynPur outputs a fault message
and the system
– and therefore also the entire downstream air humidification
system – is shut off. To resume operation the synthesizer cartridge must be
replaced at this point (for more information on replacing the cartridge, see Section
6.2).
If there is no demand for humidification for an extended period, no product can be
accepted. In this case, there is a danger of germination during downtime. To avoid
this, the system should be equipped with extensive hygiene functions. The
DRAABE BioSafe System ensures a hygienically unobjectionable operation. The
SynPur directs the water cyclically from the synthesizer cartridge over a bioreactor
that disinfects the synthesizer cartridge, or the water from the cartridge, by means
of intensive UV-C radiation (it circulates). The unit responsible for this function is
referred to as the circulation.
If the circulation of the SynPur is shut off, the pump pressure and the motor current
are monito
red as soon as the pump starts to run. The LED „Circulation“ lights up
on the display.
