ES2030 SV Functional description 1
Functional description
The controller ES2030 SV (wall mounted) is
used for the automatic control and monitoring
of single and double filter systems.
If additional control functions are required, they
can be obtained with the IF2030 card, which
can also be installed subsequently.
The software’s flexible programming capacity
and the individually adaptable hardware make
a wide range of uses in water treatment
systems possible. In combination with
individual valves, these control units can
operate ion exchanger systems and filter
systems.
For single filter systems, 6 (or 8, if the IF2030
card is fitted) in relays are available for
controlling individual valves or for controlling
pilot valves or control motors of a multifunction
valve.
Since only 6 (or 8) relays in total are available
for dual filter systems too, individual valve
systems can only be operated as simple
backwashing filters.
NOTE: For the sake of simplicity, in these
instructions the treatment process carried out
by a filter system (e.g. deferrization) is also
referred to as “REGENERATION”, as is usual
in the case of ion exchangers.
A regeneration can be initiated :
1. by manual switch
2. by remote switch (water hardness monitor,
conductivity meter, manual switch, etc..)
3. by pre selected amount (pulse water meter
required)
4. after set time intervals (e.g. every 72 hours)
5. starting on real time clock
A time window can be set to determine times
when regeneration must not take place
(delayed regeneration).
A minimum regeneration distance between
regenerations prevents regenerations being
initiated constantly if the water meter or the
remote switch is faulty.
