6.2.1 – Cleaning programming and operation.

By cleaning we mean the procedure used by the controller for removing concentration residues from the membrane. Cleaning programming consists of choosing operation and interval times and the procedure for carrying out the operation.

The following can be described in reference to tab. 4 in par. 6.2:

0t03 is the cleaning time, programmable from 0 to 99. This time may be expressed in minutes or in seconds based on the contents of the 3At flag, 1 to have the time in minutes, 0 to have it in seconds.

4t30 is the time period between two cleanings, programmable from 0 to 99. This time may be expressed in hours or in minutes based on the contents of the 1At flag, 1 to have the time in hours, 0 to have it in minutes.

1Ct is the flag which controls cleaning before supply. If programmed with a value of 1, cleaning is carried before supply startup with a duration time equal to the periodic cleaning time. If programmed with a value of 0, cleaning is not carried out.

2At is the flag which controls cleaning after supply. If programmed with a value of 1, cleaning will be carried out when the operator presses the Start / Stop key to stop supply or when the level inputs signal the presence of water in the collection tank. If programmed with a value of 0, cleaning will not be carried out.

3Ht is the flag which controls cleaning during supply. If programmed with a value of 1, when the time period between two cleanings is up, supply will stop and cleaning begins. When cleaning has finished supply starts up again. It will stop again when the programmed time period is up. If programmed with a value of 0, cleaning will not be carried out.

0At is the flag which controls pump startup during cleaning. If programmed with a value of 1, cleaning will be carried out with the pump on.

0Ht is the flag which controls the intake electrovalve during cleaning. If programmed with a value of 1, cleaning will be carried out with the electrovalve closed. Otherwise it will be open.


In summary, Aqua R.O. Simply carries out 4 types of cleaning:

- Periodic cleaning during stand-by which cannot be deactivated; - Cleaning before every supply, activated when flag 1Ct is on 1; - Periodic cleaning during supply, activated when flag 3Ht is on 1; - Cleaning at the end of every supply, activated when flag 2At is on 1;

The length of such cleanings is programmed in 0txx, time expressed in seconds if 3At is on 0 or in minutes if 3At is on 1. Periodic cleanings begin when the time programmed in 4txx runs out, expressed in minutes if 1At is on 0, or in hours if 1At is on 1.

Whatever type of cleaning amongst those indicated above is being carried out, it will be carried out with the pump off if 0At is on 0 or with the pump on if 0At is on 1. Furthermore, the intake valve will be off if 0Ht is on 1, or will be on if 0Ht is on 0.

For periodic cleaning during stand-by nothing must be done, it is already activated. Simply program the times as previously indicated. For cleaning before supply as well, simply program the 1Ct flag on 1. The times are the same as those for periodic cleaning. For periodic cleaning during supply as well simply program the 3Ht flag on 1. The times are the same as those for periodic cleaning. For cleaning after supply as well, simply program the 2At flag on 1. The times are the same as those for periodic cleaning. Obviously pre-supply cleaning, periodic cleaning during supply, and cleaning after supply may be activated individually. They may all be activated, only one or two may be activated, or none of them may be activated.

6.2.2 – Conductivity control operation.

During supply, Aqua R.O. Simply carries out a control of the quality of the water by means of a conductivity probe. The value read by the probe is compared with a threshold value called the set point (value 0.1.80 in tab. 4 of par. 6.2) and if it proves to be superior, the service electrovalve is immediately closed. At this point, the time programmed in 1txx and expressed in seconds begins counting down. If the conductivity value descends below the set point value before the intervention time runs out, the service electrovalves reopen and supply continues; if the intervention time runs out and the conductivity value is still superior to the set point value, the controller is shut down by an alarm in order to avoid polluting the water of the utility. To reset the system, the operator must intervene and press the Start / Stop key. If the controller is started up again when the conductivity value is still superior to the set point value, the system will shut down again when the intervention time runs out.

All of this is carried out only if the 2Ht flag is on 1.

6.2.3 – Pressure control operation.

Aqua R.O. Simply provides an input for the connection of a pressure indicator device. Whatever type of instrument used (gauges which read high or no pressure), it must close the contacts of the controller when an alarm condition is present. When the controller reads that the alarm input is closed, the time programmed in 2txx and expressed in seconds begins to count down. When the time is up, the controller is shut down by an alarm in order to prevent damage to the system.


To reset the system, the operator must intervene and press the Start / Stop key. If the controller is started up again with the pressure alarm input still closed, the system will shut down again when the intervention time runs out.

All of this is carried out only if the 1Ht flag is on 1.

6.2.4 – Inhibit signal operation.

Aqua R.O. Simply provides a second input, the inhibit input, for the connection of alarm devices. Unlike the previous signals, this input is always activated and when an alarm condition has disappeared, the controller automatically resets operation. The presence of an inhibit signal is indicated by a special led which lights up on the panel. If the signal appears during stand-by, the led lights up and all controller operations are shut down including both cleaning and supply startup in automatic or manual. If the signal appears during cleaning or supply, the operation in progress is stopped and the controller lights up the led on the panel. When the signal disappears, the shutdown procedure starts up again.

No matter what type of device is connected to the inhibit input, it must close the terminals when an alarm condition is present.

The intervention time may be programmed using the 3txx parameter. This may be from 0 to 10 seconds; when it is on 0, controller shutdown immediately occurs when the inhibit signal appears. Otherwise, it must run for the time indicated before the controller will be stopped.

6.3 – The floats and supply startup.

The main instrument for supply startup is the level control of the water in the collection tank. This is carried out by means of two floats, one for low level and one for high level, directly connected to the controller on terminal board J2. The floats must be the normally closed type. That is, the contacts must prove to be closed when water is present.

Supply startup takes place when the low level input opens and the high level is already open; this means that if the low level input proves to be open while the high level input is closed (for example in the case of a broken float), supply will not begin.

The signal of the floats has priority over the Start / Stop key. If it is pressed when the floats indicate the presence of water and the system is therefore in stand-by, supply will startup and immediately stop. Similarly, if it is pressed when the floats indicate a lack of water and the system is therefore being supplied, the system will stop and immediately start up again.

If one does not wish to use any level control, terminals 1 and 9 of the high level must remain open while terminals 2 and 10 must remain closed by means of a jumper. This way, supply startup and shutdown are controlled exclusively by the Start / Stop key.

If one wishes to use only one float for level control of the collection tank, terminals 9 and 10 must be closed by means of a jumper and the float must be connected between the abovementioned jumper and ground available on both terminals 1 and 2.

The drawing shown in attachment B illustrates the various connection possibilities just described and the logic sequence of the float signals during the productive cycle of the controller.


6.4 – The maintenance phase.

The maintenance phase is activated by turning off and restarting the controller by keeping the Display key pressed. During this phase, the pump and drainage and cleaning valves are activated, whereas the service valve remains off. Signals from any connected sensors and the conductivity value are ignored. This phase is indicated on the display by the wording St-C (see par. 6.5).

To exit from maintenance, simply press the Start / Stop key.

6.5 – The operational states.

The Display key permits changing the parameter shown on the display. Table 3 illustrates which data are shown by the controller. The first of these, the operational state communicates what the controller is doing in that moment. The table below is a complete list of the operational states of the Aqua R.O. Simply:
