UFS8000 System description 3
The controller is routinely delivered in the “Standby Stop" phase. The unit will not be automatically
started until this is switched on manually (see § 9.1 “Standby stop” on page 57. Once it is switched on,
the controller will no longer start in this phase after a power failure, unless this phase is activated via
the programming (see § 7.12 “Standby Stop” on page 53).
The production of water can be started depending on the level in the tanks, the “start filtration” switch
(if enabled) or manually.
It is possible to disable the installation manually during the “Filtration” phase (see § 9.5 “Filtration” on
page 58), regardless of the level in the tanks or the position of an eventual “start filtration” switch.
The installation will go on “Standby” after this phase (depending on the programming, eventually by a
backwash).
The lower bar in the main window will then show that unit has been manually switched off. The unit will
no longer be automatically switched on until the unit is manually turned on again.
It is further possible to activate a backwash or chemical rinse during the production (see § 7.7 “CEB 1”
on page 49, § 7.8 “CEB” on page 50 and § 7.9 “CEB” on page 50).
One backwash phase is activated as a standard. A second backwash phase, however, can be
activated (see § 7.6 “Backwash 2” on page 48). With this a distinction can be made between a
backwash via the top and bottom of the filter.
If an eventual chemical rinse is dependent on the number of executed backwashes, then, in the case
of two activated “normal” backwashes, “Backwash 2” is checked for the counter of the number of
executed backwashes. If “Backwash 2” is not activated, then “Backwash 1” is, of course, checked.
Also a second filtration phase (“Filtration 2”) can be activated (see § 7.3 “Filtration 2” on page 46) to
perform “top / bottom” filtration.
A chemical rinse will follow immediately after the respective backwash. If there are any chemical
rinses occurring simultaneously, then these will be carried out directly after one another.
For “Chemical rinse 2” (CEB 2), the interval can also be made dependent on the “Chemical rinse 1”
(CEB 1) phase. In this case, the cycle will be as follows:
Also see § 7.8 “CEB” on page 50.
For the testing of a "leak" in the membrane, the “Integrity Test” phase is present in the control unit.
This phase can only be achieved through the “Standby” phase (see § 9.3 “Standby” on page 57).
The test is not started automatically immediately, but the system is initially in a “rest” position. The
actual test can be started from this position (see § 9.2 “Integrity test” on page 57). There is more
information on the “Integrity Test” phase in § 7.10 “Integrity test” on page 51.
If a phase is interrupted because of an alarm situation the top bar will show there is an alarm situation.
Also shown is the phase when the alarm occurred, the cause of the interruption and how the
unit is switched on again.
§ 7.13 “Alarm” on page 53 In § 8 “Alarms” on page 54 there is more information about alarms.
