Minimum inter regeneration time limit.
This message will only appear if a minimum interval between regeneration’s has been programmed
(section 5 of the programming instructions).
Possible causes when the plant is controlled by a water meter:
Wrongly programmed capacity.
Wrongly programmed incoming water hardness.
The water meter is faulty or of the incorrect type.
Excessive demand for water e.g. a large tank being filled rapidly.
Possible causes when activated by an external water analysis equipment signal:
Poor water quality from a column which has been on standby for some time, due to the contra ion effect.
this can be overcome by fitting a flushing valve or circulation pump in the system or by reducing the
sensitivity of the analytical equipment.
IMPORTANT Regeneration is not initiated. This must be done manually, this prevents repeated
regeneration’s due to a malfunction.
Press the "UNLOCK" key indicated by the symbol
,to restore the display and reset the alarm relay, if
programmed.
Maximum programmed value exceeded.
