Display symbols:
Fig. F-2: Control panel control GENO-OSMO RO 125K
Operating display
Appears when the system is switched on using
the ▲ button (> 5 s from basic time display).
High-pressure pump
Appears when the high-pressure pump is
producing permeate (flashes with fault Er1).
Pressure booster pump
Appears when the pressure booster pump is
pumping permeate or when the power unit K2
is active.
Solenoid valve input
Appears when permeate is being produced, or
when the system is rinsing.
Rinse solenoid valve
Appears when the system is rinsing.
Solenoid valve forced withdrawal
Appears when the permeate tank is emptied to
the drain.
Level indicator permeate tank
Upper wave: Cut-off level for high-pressure
pump.
Middle wave: Switch-on level for high-pressure
pump.
Lower wave: Dry-running protection for
pressure booster pump.
Numerical display
In the information level, indicates the
time and operating parameters.
Displays the parameters of the code
levels.
Displays symbols in addition to the
error message.
Bars for water meter pulses
Flash with every 5th pulse of the water meter
p
ermeate or
c
oncentrate.
Dot appears for as long as the pressure booster
pump is blocked (after ON using ▲ button, after
exceeding the lower wave permeate tank,
acknowledge after malfunction).
Bars for operational readiness of high-pressure
pump (HP) and pressure booster pump (PS)
Shows the status of the feed water inlet
pressure switch (bar appears when pressure
is active) and PS pump operation enable
(bar appears when enabled).
P
Flashes when the pressure switch for high-
pressure pump drops out during permeate
production (lack of feed water pressure).
Bars for signal and fault signal contact
appears when the maintenance interval has
expired, high-pressure pump pressure switch
failed, conductivity pre-alarm, permeate tank
empty.
Er
appears in the event of malfunctions
Er 0 … Er 6.
Bar for close input
Appears when the system is blocked
because the on-site operational release is
missing.
Appears when HP pump is overheated.
