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 four switching steps, namely "PRODUCTION", "STAND-BY", “RINSE” and “INTERVAL RINSE”. OS3015 General description 2 "Production” step The start of the production depends on the number of programmed level switches and the position of these switches (inputs FU and EM). In the "Production" step of the reverse osmosis system first the inlet valve is opened. After an adjustable delay time of 1 - 999 seconds the high-pressure pump is activated. The following values are monitored: - Low water pressure input - Exceeded pressure input - Tank high-level input - Tank low-level input - Stop A built-in working hours counter registers the duration of the "PRODUCTION" step from one minute to 65.000 hours. "Stand by" step No water flows during the "Stand by" step. The input valve is closed and the high- pressure pump is switched off. The following values are monitored: - Tank high-level input - Tank low-level input OS3015 General description 3 "Rinse” step The step “Rinse” will be activated (if programmed in step 10.1) after finishing the step “Production”. The concentrate valve will be opened always. The inlet valve and high pressure pump can be programmed. The high pressure pump can be switched on with a programmable delay. The following values are monitored: - Low water pressure input (only when inlet valve is opened) - Exceeded pressure input - Tank high-level input - Tank low-level input - Stop "Interval Rinse” step The step “Interval Rinse” will be activated (if programmed in step 11.1) when there is no water production for a programmable time. The concentrate valve will be opened always. The inlet valve and high pressure pump can be programmed. The high pressure pump can be switched on with a programmable delay. The following values are monitored: - Low water pressure input (only when inlet valve is opened) - Exceeded pressure input - Tank high-level input - Tank low-level input - Stop OS3015 Measuring and function display 4 Measuring and function display First LCD line The first line of the LCD display shows the actual phase of the system: "Production", "Stand-by", “Rinse” and “Int.Rinse”.

Software versionOS3015 1.01.00OS3015 Alarms 9 Alarms Exceeded pressure The "excess pressure" input has been activated. The system is switched off and automatically switched on again after a programmed delay time. Possible cause: set value for the system was changed, soiled membrane. Low water pressure The "Low pre-pressure" input has been activated. The system is switched off and automatically switched on again after a programmed delay time. The message disappears as soon as the "low pre-pressure" signal has been cancelled. Possible cause: no water pressure Signal Overpressure Signal Low pressure OS3015 Alarms 10 Stop The "Stop" input has been activated. The system is switched off and switched on again when the signal at the input has been cancelled. The message disappears as soon as the "low pre-pressure" signal is cancelled. Signal Stop OS3015 Input functions 11 Input functions The ‘Low water pressure’ (LP) and ‘Tank full’ (FU) inputs are standard available. The third IN input depends on the programming : - ‘Tank empty’ for two level switches - ‘Exceeded pressure’ for one level switch - ‘Stop’ for one level switch Low water pressure The ‘Low water pressure’ (LP) input is used to prevent the pump from running dry. In step 6.1 you can program the delay before the system is switched off. The LCD display shows the message ’Low water pressure’ and in step 7.1 you can set whether the alarm relay must be activated for this message. The system switches on again automatically after the delay programmed in step 6.3. The input function is active when the contact is open. Tank full / Tank empty The input functions ‘Tank full’ (FU) and ‘Tank empty’ (EM) are used for automatically filling a storage tank. In step 5.1 you can select whether one or two level switches are used. If you only use one level switch, then the ‘IN’ input is used for excess pressure safety. Replenishing takes place after : - a programmable delay when programmed for one level switch - a fixed one-second delay when programmed for two level switches The FU input function is active when the contact is open. The EM input function is active when the contact is closed. OS3015 Input functions 12 Exceeded pressure The ‘Exceeded pressure’ (EP) input function can only be used if only one level switch is used. In step 6.2 you can program the delay before the system is switched off. The LCD display shows the message ’Exceeded pressure’ and in step 7.1 you can set whether the alarm relay must be activated for this message. The system switches on again automatically after the delay programmed in step 6.3. Stop The ‘Stop’ (ST) input function can only be used if only one level switch is used. In step 6.3 you can program the delay before the system is switched off. The LCD display shows the message ’Stop’ and in step 7.1 you can set whether the alarm relay must be activated for this message. The system switches on again automatically when the input is no longer active. OS3015 Output functions 13 Output functions The output functions ‘Inlet valve’ (IV) and ’High-pressure pump’ (PU) are standard available. The output functions ‘Alarm’ (AL) and ’Concentrate valve’ (CV) can be selected for the third relay output (terminals 9,10 and 11). Inlet valve The input valve is opened as soon as the ‘Production’ step, “Rinse” step (if programmed) or “Int.Rinse” step (if programmed) is activated. The maximum current load on this output is 8A (fused). High-pressure pump The high-pressure pump is activated after the input valve has been opened with a delay time programmed in step 8.1. The maximum current load on this output is 8A (fused). Alarm The alarm relay can be activated for certain events like: - low water pressure - exceeded pressure - stop You can program whether or not the alarm relay must be energised in case of malfunction. Concentrate valve The concentrate valve is only opened during the rinse functions. OS3015 Display and modification of set points 14 Display and modification of set points 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 ‘|’. OS3015 Display and modification of set points 15 1. Language In this step you can set the language. 5. Level switches The storage tank is replenished via level switches. Level switch = 1 : The storage tank is replenished immediately when the water level falls below the full level. There is always a maximum volume available. The ‘IN” input can then be used for an excess pressure safety. Level switch = 2 : Alternatively, the system can be filled via two level switches. In that case the system is switched on when the low level is reached and switched off again when the high level is reached. Advantage: the system is switched on and off less frequently. The ‘IN’ input is used for connecting the low-level switch. Step no.: 1.1 D Nl E F I Step no.: 5.1 Level switch 1 OS3015 Display and modification of set points 16 The switch-on delay for the high level switch can be programmed from 0 to 99 seconds. This step is only available when programmed for one level switch. 6.
