Switching from parallel to alternate
If parallel switching was selected when
programming filter switching at program step
1.4 then it is possible to switch over to
alternate service. When this is done, the filter
which has the least capacity remaining is first
to regenerate.
Bear in mind that the other filter has also
become partially saturated, so that the system
may become overloaded after it is switched to
alternate service. It is therefore best to start a
regeneration manually after switching over.
Press the ‘OUT1’ and ‘OUT2’ keys
simultaneously.
Fast cycle
Simultaneously press the function keys with
the symbols and .
After 3 seconds the internal program clock
switches over from minute pulses to second
pulses. The fast cycle activated only affects the
current regeneration phase, the following
phases will run at normal speed.
NOTE: If you want to cycle through the various
regeneration phases using the fast cycle, wait
for two or three minutes after each stage to
allow all the valves to move into their new
positions.
NOTE: If regeneration medium has already
been primed, the filter must be rinsed before
the system is put into service.
Regeneration without initialisation
For maintenance purposes it is sometimes
necessary to check the regeneration program
without initialising the pulse counter or
recalculating the filter capacity. Simultaneously
press the function keys with the symbols
and .
In single filter system, the service filter will be
regenerated after 4 seconds without
initialisation and without recalculation of the
filter capacity.
In two filter systems the standby filter will be
regenerated and the displayed capacity values
will not be changed.
If the service filter is to be regenerated., a ‘filter
exchange without program initiation’ must be
carried out first.
NOTE: This only applies for single filter and
alternating filter service.
(Program steps 5.1, 5.2 or 5.3 = YES).
Regeneration of Filter 1 ONLY
Simultaneously press the function keys with
the symbols and .
After 4 seconds, Filter 1 only will be
regenerated without initialisation and without
recalculation of the filter capacity.
NOTE: This only applies for series or parallel
connection (program steps 5.4 or 5.6 = YES).
Regeneration of Filter 2 ONLY
Simultaneously press the function keys with
the symbols and .
After 4 seconds, Filter 2 only will be
regenerated without initialisation and without
recalculation of the filter capacity.
NOTE: This only applies for series or parallel
connection (program steps 5.4 or 5.6 = YES).
