Functional Description
The OS 3030 (wall-mounted) controllers are
used for the fully automatic monitoring and
control of water treatment plant, which operate
on the basis of the process of reverse osmosis.
The controller can be expanded to include a
programmable input and two programmable
outputs using the IF plug-in card.
The following description relates to a standard-
ised plant. Your existing plant can be adapted
depending on its size, on the quality of the
untreated water, on the use of demineralised
water and on local requirements. In any event,
pay particular attention to information and de-
scriptions relating specifically to your plant.
The basic data programmed into your control-
ler may be altered at any time. A code number
can be set as a safeguard against unauthor-
ised programming and calling up the mainte-
nance function.
All of the program data is saved in the event of
a power failure.
The installation can be switched off manually
using the OFF switch. Its control will then
switch to sleep mode (the SLEEP phase).
The controller differentiates between different
phases, which are described below.
PRODUCTION phase
The plant supplies treated water during the
PRODUCTION phase. In general, the un-
treated water floats via the input valve to the
pressure pump and on to the osmosis module.
A salt-enriched part (concentrate) flows into
the duct via the concentrated control valve.
The other part, the demineralised water (per-
meate), flows into a reservoir or to the con-
sumer.
The plant may come with different design fea-
tures, such as multi-stage systems, concen-
trate recirculation or a permeate flush valve
which is activated depending on conductivity.
Up to 3 stages, each lasting between 0 and
999 seconds, can be installed upstream of the
PRODUCTION phase. A production phase is
always ended by switching off the high-
pressure pump for 3 seconds.
The following values are monitored during the
PRODUCTION phase provided the controller is
properly programmed, the IF plug-in card
(available as an optional extra) is plugged in or
the requisite sensors are connected to the
inputs:
Conductivity too low (
programmable
)
Conductivity too high (
programmable
)
Reservoir full input
Reservoir empty input
Stop input (
programmable
)
Excess pressure input
Concentrate throughput input
External alarm switch input (
programmable
)
Low-water input (
programmable
)
Motor circuit-breaker input (
internal
)
An integrated elapsed-time meter records how
long the PRODUCTION phase has been
switched on to the precise minute, up to
65 000 hours ".
STANDBY phase
No treated water flows during the STANDBY
phase.
A stages lasting between 0 and 999 seconds
can be installed upstream of the STANDBY
phase.
The following values are monitored during the
STANDBY phase provided the controller is
properly programmed, the IF plug-in card
(available as an optional extra) is plugged in or
the requisite sensors are connected to the
inputs:
Reservoir full input
Reservoir empty input
Motor circuit-breaker input (
internal
)
"SLEEP" Phase
All in- and outputs are switched off in the
"SLEEP" phase. This phase is activated by
pressing the OFF button.
It can be taken out of sleep mode by pressing
the ON button.
