Minimum time between regenerations
5. Minimum time between regeneration’s.
Based on the capacity of the installation, the incoming water hardness and
flow rate, the minimum time between two regeneration cycles can be
calculated.
With installations utilising brine tanks it may be necessary to allow time for full
strength brine to be produced, the actual time will depend upon the type of
brine system used but could exceed 4 hours.
When there are very large requirements of water, for instance when filling a
large tank, if this minimum time requirement if not taken into account and the
plant may be insufficiently regenerated because of unsaturated brine.
If a water softener installation is also equipped with water hardness monitoring
equipment, the minimum time period between regeneration’s must be
programmed. Otherwise, should there be a defect e.g. with the monitoring
equipment the unit will continuously regenerate.
The minimum time between two regeneration’s can be anything between 1
and 999 hours.
If a regeneration cycle is initiated before the programmed time has been
reached then a warning is shown in the LCD display. The warning relay can
also be activated if desired.
If a regeneration cycle is initiated before the programmed time has been
reached then an alarm is shown in the LCD display. The alarm relay can also
be activated if desired.
