4.3.7
Regeneration Release according to Minimum Quantity
If the filter should be regenerated according to an external signal but also following a
specific minimum quantity, the regeneration release is set to Quality in the FS-21 configu-
ration and a value greater than 0 m
3
must be set for the minimum quantity.
selection 'Reg. Extern' yes
or
no
setting range 'minimum Quantity' 0 … x
m³
Note
: The minimum Quantity is an amount, which is related to the filter capacity (
ref. to
. Within these limits, it can freely be adjusted by the device operator. It serves
to avoid a premature regeneration release – e.g. quality dependent release (
ref. to chap.
4.3.3 - External - / Quality dependent Regeneration Release
), if the filter doesn’t provide
good water, immediately after the standby time. The pre-setting for the minimum quantity is
done in the submenu 'Filter values' (
see chap. 4.3.11
4.3.8
Regeneration Release according to Minimum Quantity (delayed)
If the filter should be regenerated according to an external signal but also following a
specific minimum quantity and at a certain time, the regeneration release is set to Time,
Quantity and Quality in the FS-21 configuration.
selection 'Time dept. Reg ' / 'Quality ( external ) Reg.': yes
or
no
setting range 'minimum Quantity': 0 … x
m³ *
* Note:
The maximum of adjustable minimum quantity 'x' depends on the configured filter
capacity (
see above and chap. 4.3.11.1 ).
4.3.9
Regeneration Release according to Maximum Quantity
If regeneration of the filter is selected according to an external signal, it is possible to define
its release through a maximum quantity. The filter is then regenerated on reaching a
maximum quantity even if the external signal has not been received.
Release via the maximum quantity prevents a filter being 'run too long' if, for example, the
external signal from a water analysis unit fails.
selection: yes
or
no
Note:
The maximum quantity corresponds to the parameterised filter capacity water (
ref. to
chap. 4.3.11 Setting the Regeneration Quantities
). If filter regeneration according to
maximum quantity is selected,
regeneration according to quantity (
ref. to chap. 4.3.5 / 4.3.6
) is deactivated.
the value for the maximum quantity is to be entered in the 'filter capacity' field.
4.3.10 Regeneration Release according to Maximum Quantity (delayed)
If the filter should be regenerated according to an external signal but also following a
specific maximum quantity and at a certain time, the regeneration release is set to Time,
Maximum Quantity and Quality in the FS-21 configuration.
