During service and during the regeneration of
the system, various signals are given
depending on the type of controller and its
programming.
These signals can be signalled with the built-in
buzzer and displayed in the LCD display. If the
extension card IF2030 is installed an additional
relay can be selected as warning relay (step
15).
Press the key OUT1 or OUT2 to clear the
buzzer and any activated warning relay. The
LCD display is only cleared when the warning
signal is no longer active.
Capacity exceeded
This display can only appear with a double
filter system.
While one of the filters is regeneration, the
other was also called on to regenerate. The
warning in the LCD display is cleared when
this filter starts regeneration.
Possible causes where activated by the water
meter :
Incorrect setting of capacity, supply water
hardness or of the water meter itself.
Overloading of the system e.g. by filling a
large container.
Possible causes where activated externally by
a water analysis device :
Saturation of a system newly put into use,
caused by the negative ion effect.
Solution : fit a flushing valve or circulation
pump. Reduce the sensitivity of the analysis
Device.
Other possible causes :
Poor regeneration of the filter due e.g. to
regeneration medium not being present or
being incorrectly primed.
NOTE: In two-filter systems, after a flow
dependent regeneration activation the
regeneration of the second filter will follow
immediately the current regeneration ends.
However in the case of external activation of
the regeneration, e.g. by a water analysis
device, the regeneration does not follow, as it
can be assumed that the hardness warning
occurred as a result of a standstill hardening of
the standby filter. The second filter is only
regenerated if the relevant start signal is still
present at the end of the current regeneration
or if it reset.
In the case of ion exchangers with a salt
release valve, if no brine has yet formed for the
second filter, stop the regeneration by
switching off the unit.
Power failure
No data are lost if there is a power failure.
When power is restored the control panel will
return to the same setting with the same
values.
NOTE: If the system is at the regeneration
setting when power is lost, the filter may
become over saturated again if the water
pressure continues during this time and it is
washed by supply water over a period of
hours.
If so, stop the regeneration and then re-start.
Refill regeneration medium
Refill regeneration medium.
NOTE: An imminent regeneration will not be
carried out unless either regeneration medium
is again available or the “start regeneration”
key with the symbol is pressed.
In the case of alternately operating two filter
systems, the unit switches over to the standby
filter.
Delayed regeneration
The required regeneration will not start until the
time shown in the LCD display. However the
regeneration can be started immediately by
pressing the “start regeneration” key ( ).
This display is only shown if activation of
“delayed regeneration” was selected in step 19
or 21.
