8. Minimum regeneration distance
The minimum distance between two regenerations in ion exchangers can be
calculated and monitored on the basis of the system’s capacity and the maximum
water demand.
If the treatment unit is additionally monitored using an automatic water hardness
monitoring device, the minimum distance between regenerations must be
programmed in, as otherwise any fault in the hardness monitoring device or the
treatment unit (such as faulty priming of chemicals) may result in continuous
regenerations.
This applies to filter systems monitored by a differential pressure gauge.
A setting between 1 and 999 hours can be entered as the minimum time distance
between two regenerations.
If an attempt is made to initiate a regeneration automatically before the set time
has elapsed (by water meter, time interval or analysis device), the appropriate
message is shown on the LCD display, and the built-in buzzer sounds if
programmed at program step 21.
Where the IF2030 card is installed, a warning relay can also be activated (program
step 19).
You can determine whether the regeneration is to be carried out immediately after
the end of the ‘minimum regeneration distance’ (Y/N) or whether the next
regeneration has to be started manually.
When the message ‘minimum regeneration distance’ is displayed, you can
determine whether the valve of the system in service is to stay open until
regeneration is initiated, with the possibility that it will supply incompletely treated
water (Y/N) or whether that the valve should close (Y/N) with the result that the
system does not supply any more water.
