Functioning
Switching on and power failure
After switching the unit on and after each power failure, the plant automatically returns to the Standby position. Prior to
the Standby-position another flush takes place according to the programmed flushing duration (see programming). The
plant can either be switched on manually by pressing the
A
RUN/STOP
@
key ("Production/Standby") or, e.g.,
automatically via existing level transmitters in the storage tank.
Production / Run
Use the
A
RUN/STOP
@
("Production/Standby") key to switch on the pressure pump(s) of the osmosis plant. The input
valve opens and after a delay time the motor of the pressure pump starts . During production, it is possible to monitor the
raw water pressure in front of the pressure pump (dry-running protection) as well as the pressure behind the pressure
pump (overpressure protection) via pressure switches and to monitor the concentrate (concentrate flow) via a flow
controller if the osmosis plant is equipped with the appropriate sensors. Additionally, the permeate conductivity is
measured, displayed and compared with a minimum and maximum limit value.
The switching on and off can also take place automatically via level transmitters in the storage tank if the osmosis plant
is equipped with a storage tank.
It is possible to interrupt the production temporarily via an external switch (input "STOP") in order to, e.g., regenerate a
pre-connected softening plant.
Standby
Press the
A
RUN/STOP
@
("Production/Standby") key if water is no longer required. The pressure pump is switched off and
the display shows "Standby". If the osmosis plant is equipped with a storage tank, the switching on and off can also take
place automatically via level transmitters in the storage tank. In the case of plants with a flush valve, there is a re-rinsing
phase (flush after production) prior to the position "Standby". During this time,
A
Flush
A
is shown on the display and the
control lamp
A
flush valve
A
(
A
FV
@
) lights up.
While switching from production to flush the pressure pump is, with opened input and flush valve, switched off for 5
seconds in order to achieve a pressure compensation of the plant.
The water pressure before and after the pressure pump, the concentrate flow as well as the conductivity limit values are
not monitored in the
A
Standby
@
position.
Flush after production
The osmosis plant can be equipped with a flush valve (connection "FV") in order to avoid unacceptable high deposits at
the units. Flush is started after the end of the production if the storage tank is filled or by pressing the
A
RUN/STOP
@
("Production/Standby") key.
Program the necessary flushing duration in the basic program under "Flushing duration". Please set the flushing duration
to 0 minutes if no flush is to take place after the production.
Flush is cancelled as soon as the
A
RUN/STOP
@
("Production/Standby") key is pressed or if water is requested via a limit
transmitter in the storage tank.
Interval flush
After the last switch off (in the Standby position), flush can occur at fixed intervals. Unacceptable bacterial contamination
of the units is avoided due to this interval flush. Enter the interval time (0 - 999 hours) and the flushing duration (1 - 99
minutes) in the basic program ("Interval flush").
Flush is cancelled as soon as the
A
RUN/STOP
@
("Production/Standby") key is pressed or if water is requested via a limit
transmitter in the storage tank.
With production stop, no interval flush takes place
. If an interval flush is not desired, the interval time (hours) has to be
entered as
@
0
@
.
Quality flush and emergency service
During quality flush switch off at too high conductivity (LV Permeate Max: Switch off) should not be activated. During
production, it is checked whether the permeate conductivity rises above the upper limit value (LV Permeate Max).
If it is too high and
quality flush (Quality flush: ON) has been programmed, quality flush is started for the programmed
duration after the end of the set test time for the upper limit value.
It is switched back to production if the conductivity falls again due to the flush. However, if the conductivity remains as
high, the
emergency service starts after the quality flush. The emergency service is not shown extra on the display
(display:
@
Production
@
).
Emergency service is terminated as soon as the conductivity is below the upper limit value.
