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

Software version
The factory regularly updates the software. Changes are made as necessary to
adapt the product to the latest insights and requirements. Displayed is the number

UF3020 Input functions 11
Input functions
The ‘Over pressure’ (CC), ‘Low level raw water tank’ (LP) and ‘High level clean
water tank’ (FU) inputs are standard available.
Overpressure
The ‘Over pressure’ (CC) input is used to prevent the installation from to high
pressures.
In step 3.3 you can program the delay before the system is switched to “Alarm”.
You can leave the “Alarm” step by pressing the button when the when over pressure
situation is solved.
The input function is active when the contact is open.
Low level raw water tank
The input function ‘Low level raw water tank’ (LP) is used for checking the level of
water in the raw water tank.
The controller will respond immediately when the contact is opened and will switch
into the step “Standby”.
In step 3.1 you can program the delay for the installation to switch back the step
“Filtration” (through the step “Pre flush”, if programmed in step 2.1).
The controller is detecting low level when the contact is open.

UF3020 Input functions 12
High level clean water tank
The input function ‘High level clean water tank’ (FU) is used for checking the level of
water in the clean water tank.
The controller will respond immediately when the contact is opened and will switch
into the step “Standby”.
In step 3.2 you can program the delay for the installation to switch back the step
“Filtration” (through the step “Pre flush”, if programmed in step 2.1).
The controller is detecting high level when the contact is open.

UF3020 Output functions 13
Output functions
The outputs are free programmable for each process step.
There are no special output functions available.

Attention
Changing settings may only be done by qualified electrical engineers.
When the system is put into operation, the operational data of the reverse osmosis
system can be controlled by entering basic values.
You can change these values at any time and they are not erased in case of a
power failure.
To prevent unwanted changes in the programme, you must keep the
key depressed for four seconds before the system allows you to make
changes
With the same key you can then browse through the programming.
You leave the programming mode automatically about two minutes after
the last keystroke or by pressing the key combination as shown.
With the upper key you can move the cursor.
By pressing the lower key you can change numeric values within the
given range that you have first marked with the cursor.
For questions with a choice, you can also use this key to switch
between ‘-‘ en ‘|’.
