Water meter, flow pulse
6. Water meter
Using a contact head/reed water
meter, the volume of treated water
produced is measured and, when the
pre-programmed quantity of water
has been supplied, regeneration is initiated.
The LED display usually shows the capacity remaining i.e. the amount of water
which can be treated before regeneration is required.
NOTE: If no water meter is used (e.g. regeneration takes place only at time
intervals), the system's full capacity is always shown.
The impulse rate (k factor) of the
water meter can be programmed for
values of between 1 and 9999,9 litres
per pulse/contact closure.
7. Flow-pulse
(
Standard Program
)
.
For every impulse of the water meter
the pulse relay K9 operates once. The
contact duration can be programmed
in the range of 0,2 to 999,9 seconds.
These output pulses can be used for
control of a dosing pump or a dosing monitoring system or to operate a remote flow
rate measuring/control system.
If the interval between successive water meter pulses/contacts is less than the
programmed output duration the impulses are stored by the control and the output
relay reactivated the appropriate number of times. There is an interval of 0,5 sec
between output pulses.
7. Flow-pulse
(De alkalisation)
.
If the de alkalisation software option
has been selected, Relay K9 is used
to control the fill chemical fill valve of
the chemical tank.
This valve operates for a pre-
programmed period of time when regeneration is initiated before the regeneration
cycle commences. The refill time can be programmed for values between 5 and 60
minutes.
As soon as the chemical tank level system signals that the required volume of
chemicals is present in the tank, by closing the “Chemical” input, the regeneration
cycle will commence even if the pre-programmed time has not expired. If the
“Chemicals” input is not operated before the pre-programmed time has expired an
alarm condition results.
It can be determined whether the
operating valve of single filter systems
is to be closed or open during the
topping-up period.
IMPORTANT
The control is able to operate several different types of plant. If the “Hardness” key is held down when
the power is switched on the control offers the choice of the "Standard" water softener/filter program or
a "De- alkalisation” program, selectable by the "#"-key. If Standard "Y" is selected and the "#"-key is
pressed again a "Motor valve" option is available ( see page 27: Electrical control )
