UF3020 General description 1
General description
The UF3020 operating control is used to fully automatically monitor and control very
simple ultra filtration water treatment systems.
The basic values that have been programmed into the operating control can be
changed at any moment and are not erased in case of a power failure.
The control has seven switching steps, namely "Standby", "Filtration", “Pre flush”,
“Flush1”, “Backwash”, “Flush2” and “Alarm”.
The steps “Pre flush”, “Flush1” and “Flush2” are programmable to be switched off
and on.
The state of the outputs during a step is programmable for each step.
UF3020 General description 2
"Standby” step
During standby the low level (RW tank) and high level (CW tank) will be checked.
When both are not activated the installation will switch to “Pre flush“ (if activated
in step 2.1) and then to “Filtration“.
When the push button will be pressed the controller will start a flush.
All outputs free programmable.
The following values are monitored:
-Low level, raw water tank
-High level, clean water tank
"Filtration" step
During filtration the low level (RW tank) and high level (CW tank) will be checked.
When one or both are activated the installation will switch to standby.
When the push button will be pressed the controller will start a flush.
After a programmed interval time the installation will switch to “Flush1” (if activated
In step 2.1).
All outputs free programmable.
The following values are monitored:
-Overpressure
-Low level, raw water tank
-High level, clean water tank
-Push button
UF3020 General description 3
"Pre flush” step
This step has to be activated in step 2.1 (PFL).
The step “Pre flush” will be activated after switching power on (when program step
4.1 is programmed for ‘PFL)’ or when the installation will go to the “Filtration” step
after “Standby”.
After a programmed time the installation will go into “Filtration”.
All outputs free programmable.
The following values are monitored:
-Overpressure
"Flush 1” step
This step has to be activated in step 2.1 (FL1).
The installation will switch to “Flush 1” after the “Filtration” time has passed.
You can also start “Flush 1” manually by pressing the push button during “Standby”
or “Filtration”.
After a programmed time the installation will switch to “Backwash”.
All outputs free programmable.
The following values are monitored:
-Overpressure
UF3020 General description 4
"Backwash” step
The installation will switch to “Backwash” after the “Flush 1” time has passed.
After a programmed time the installation will switch to “Flush 2”,
All outputs free programmable.
The following values are monitored:
-Overpressure
"Flush 2” step
This step has to be activated in step 2.1 (FL2).
The installation will switch to “Flush 2” after the “Back wash” time has passed.
After a programmed time the installation will switch to “Filtration” or “Standby”
(depending on the state of the level switches).
All outputs free programmable.
The following values are monitored:
-Overpressure
UF3020 General description 5
"Alarm” step
The installation will switch to “Alarm” when there is a overpressure situation or when
program step 4.1 is programmed “AL”.
During alarm the over pressure switch and the button will be checked.
When pressing the button and the pressure is ok the installation will proceed the
process step that was interrupted. The interval time for the flush and back wash
steps will also proceed and not be reset.
All outputs will be deactivated.
The following values are monitored:
-Overpressure
-Push button
