5. Input function parameters
Parameters still have to be input for some input functions. The "full/empty
level switch" and "power failure" programming steps are always displayed.
The others are only displayed if the function has been selected beforehand.
Full/empty level switch
The
reservoir
can
be
refilled via a (full) level
switch. The system comes
on immediately if the level
drops below FULL.
Advantage: the full reservoir capacity is available to the consumer all the
time.
Select:
Level switch = 1.
Alternatively, the reservoir may be filled via two level switches. The osmosis
plant comes on when the reservoir runs dry. When the level in the reservoir
rises to FULL, the osmosis plant cuts out.
Advantage: the system is switched on and off less frequently.
Select:
Level switch = 2.
If there is no reservoir activated, the system can only be switched on and off
manually.
Select:
Level switch = 0.
General note:
The "Reservoir Empty" and "Reservoir Full" statuses are displayed on the
LCD if the buzzer and the alarm relay have been activated, irrespective of the
setting selected.
Concentrate control
The response time for the
concentrate control switch
can be
programmed to
between 1 and 999 sec-
onds.
The
controller
can
be
programmed to allow a few
more attempts to switch on
the system on if the con-
centrate level is low before it cuts out completely. It can only then be switched
back on by pressing "ON". A setting of between 0 and 9 is permissible.
If you select 0, the system does not cut out completely. The system comes
back on as soon as the flow of concentrate restarts and permeate is requested.
If you select 1, the system cuts out and must be restarted manually.
If you select values of between 2 and 9, the system makes 1-8 attempts to come back on, despite the
current low-concentrate alarm signal. It then cuts out and must be restarted manually.
If between 2 and 9 attempts to switch the system
back on are programmed, the delay between auto-
matic switch-on attempts must be set. You may
specify a delay of between 1 and 999 seconds.
