ENGLISH

The power supply cable must never be used to carry or shift the pump.

Never pull on the cable to detach the plug from the socket.

If the power cable is damaged, it must be replaced by the manufacturer or by their authorised technical assistance service, so as to avoid any risk.

Failure to observe the warnings may create situations of risk for persons or property and will void the product guarantee.

RESPONSIBILITY

The Manufacturer does not vouch for correct operation of the electropumps or answer for any damage that they may cause if they have been tampered with, modified and/or run outside the recommended work range or in contrast with other indications given in this manual.

The Manufacturer declines all responsibility for possible errors in this instructions manual, if due to misprints or errors in copying. The Manufacturer reserves the right to make any modifications to products that it may consider necessary or useful, without affecting their essential characteristics.

1. GENERAL

The product is an integrated system composed mainly of a self-priming multi-stage centrifugal electropump, an electronic circuit that controls it and an expansion vessel. Cooling of the motor with water rather than air ensures less noise in the system.

1.1 Applications

Water systems supply and pressure boosting domestic use. On the outside the product appears as a parallelepiped that presents 6 faces as shown in Fig.1.

ENGLISH

“IN” the system from which you want to draw water (well, cistern,...) and connect the delivery system to the connection marked “OUT”. There is also a ventilation grid. The 3/8” cap allows drainage of the system in the case of horizontal installation. There is also a ventilation grid.

Face E: the 4 brass threads form the seat for the 4 support feet in the case of horizontal installation. The main function of the 1" cap is drainage of the system in the case of vertical installation. There are also 2 ventilation grids.

Face F: as indicated by the label to be removed, the 1" cap next to the word "IN" on face C has a dual function: in the case of horizontal installation, the outlet that is closed by the cap acts as the system's loading door (see below "loading operations", par. 2.2.3); in the case of vertical installation, the same outlet can act as the input hydraulic connection (exactly like the one marked "IN" on face C and as an alternative to it). The other 1" cap gives access to a second delivery connection that can be used at the same time as or alternatively to the one indicated with "OUT" on face C. The user interface panel is composed of a display and a keyboard and its function is to set the system, query its status and communicate any alarms. The door closed by 2 screws gives access to a special maintenance compartment: cleaning of the non-return valve and resetting of the tank preload pressure.

The system can be installed in 2 different configurations: horizontal (Fig.4) or vertical (Fig.5).

1.2 Description of the Integrated Inverter

The electronic control integrated in the system is of the type with inverter and it makes use of flow, pressure and temperature sensors, also integrated in the system.

By means of these sensors the system switches on and off automatically according to the utility's needs and it is able to detect conditions of malfunction, to prevent and indicate them. The Inverter control ensures different functions, the most important of which, for pumping systems, are the maintaining of a constant pressure value in delivery and energy saving.

• The inverter is able to keep the pressure of a hydraulic circuit constant by varying the rotation speed of the electropump. In operation without an inverter the electropump is unable to modulate and, when there is an increase of the request for flow, the pressure necessarily decreases, or vice versa; this means the pressures are too high at low flow rates or too low when there is an increased request for flow.
• By varying the rotation speed according to the instantaneous request of the utility, the inverter limits the power supplied to the electropump to the minimum necessary to ensure that the request is satisfied. Instead, operation without an inverter contemplates operation of the electropump always and only at maximum power.

or the configuration of the parameters see chapters 4-5.

1.3 Integrated Expansion Vessel

The system is complete with an integrated expansion vessel with a total capacity of 1 litres. The main functions of the expansion vessel are:

• to make the system elastic so as to protect it against water hammer;
- to ensure a water reserve which, in the case of small leaks, maintains the pressure in the system for a longer time and spreads out needless restarts of the system which otherwise would be continuous;
- when the utility is turned on, ensure the water pressure for the seconds that the system takes to switch on and reach the correct rotation speed.

It is not a function of the integrated expansion vessel to ensure a water reserve such as to reduce interventions of the system (requests from the utility, not from a leak in the system). It is possible to add an expansion vessel with the capacity you prefer to the system, connecting it to a point on the delivery system (not a suction point!). In the case of horizontal installation it is possible to connect to the unused delivery outlet. When choosing the tank, consider that the quantity of water released will also depend on the parameters SP and RP that can be set on the system (chapters 4-5).

The expansion vessel is preloaded with pressurised air through the valve accessible from the special maintenance compartment (Fig.1, Face F).

The preload value with which the expansion vessel is supplied by the manufacturer is in agreement with the parameters SP and RP set as default, and anyway it satisfies the following equation:

• SP = Set Point (chapter 5.3.1) in bar
• RP = Reduction of pressure to restart (chapter 5.5.1) in bar

So, by the manufacturer: Pair = 3 - 0.3 - 0.7 = 2.0 bar

If different values are set for the parameters SP and/or RP, regulate the valve of the expansion vessel releasing or letting in air until the above equation is satisfied again (e.g.: SP=2.0bar; RP=0.3bar; release air from the expansion vessel until a pressure of 1.0 bar is reached on the valve).

ENGLISH

Failure to respect the above equation may lead to malfunctions of the system or to premature breakage of the diaphragm inside the expansion vessel.

Considering the expansion vessel capacity of only 1 litres, any operation to check the air pressure must be performed by connecting the pressure gauge very rapidly: on small volumes the loss of even a limited quantity of air can cause an appreciable drop in pressure. The quality of the expansion vessel ensures the maintenance of the set air pressure value, proceed to check it only at calibration or if you are sure of a malfunction.

Any operation to check and/or reset the air pressure must be performed with the delivery system not under pressure: disconnect the pump from the power supply and open the utility nearest to the pump, keeping it open until it no longer gives any water.

The special structure of the expansion vessel ensures its quantity and duration over time, especially of the diaphragm which is typically the component subject to wear for items of this type. However, in the case of breakage, the entire expansion vessel must be replaced and exclusively by authorised personnel.

2. INSTALLATION

The system is designed for indoor use: do not install the system outdoors and/or directly exposed to atmospheric agents.

The system is designed to be able to work in environments where the temperature remains between 1^ C and 50^ C (on condition that the electric power supply is ensured: see par. 5.6.8 “anti-freeze function”). Esybox mini operates correctly with a difference between ambient and liquid temperatures of no more than 30^ C (with the ambient temperature higher than the liquid temperature). Besides this temperature difference, the humidity limit must not exceed 50%, otherwise there is a risk of condensation forming, which can cause irreparable damage to the electronic board.

ENGLISH

Seven yellow warning symbols with exclamation marks, arranged vertically in a row.

The system is suitable for treating drinking water.

The system cannot be used to pump salt water, sewage, inflammable, corrosive or explosive liquids (e.g. petroleum, petrol, thinners), greases, oils or food productsi.

The system can suck up water with a level that does not exceed the depth of 8 m (he height between the water level and the pump suction mouth).

If the system is used for the domestic water supply, respect the local regulations of the authorities responsible for the management of water resources.

When choosing the installation site, check that:

• The voltage and frequency on the pump's technical data plate correspond to the values of the power supply system.
• The electrical connection is made in a dry place, far from any possible flooding.
  • The earth system must comply with the regulations.

The possible presence of a small amount of water inside the product is a residue of the testing process.

If you are not sure of the absence of foreign bodies in the water to be pumped, install a filter on the system intake that is suitable for catching impurities.

The installation of a filter on intake causes a decrease of the system's hydraulic performance proportional to the loss of load caused by the filter itself (generally the greater the filtering power, the greater the fall in performance).

Choose the type of configuration you intend to use (vertical or horizontal) considering the connections to the system, the position of the user interface panel, and the spaces available according to the indications below. Wall installation is possible, see par. 8.2.

2.1 - Vertical Configuration

Screw the 4 rubber feet supplied loose in the package into the brass seats in face C. Put the system in place, taking into account the dimensions in Fig.6.

• The distance of at least 10mm between Face E of the system and any wall is obligatory to ensure ventilation through the grids provided. If you expect to have to drain the system from its discharge door and not from the system, leave a further distance sufficient to manoeuvre the drainage cap.
• The distance of at least 10mm between Face B of the system and an obstruction is obligatory to let out the power supply cable to the mains socket.
• The distance of at least 200mm between Face A of the system and an obstruction is recommended so as to be able to remove the door and gain access to the technical compartment.

If the surface is not flat, unscrew the foot that is not touching and adjust its height until it contacts the surface so as to ensure the stability of the system. The system must in fact be placed in a safe and stable position, ensuring that its axis is vertical: it must not be in an inclined position.

2.1.1 Hydraulic connections

Make the connection at input to the system through the mouth on Face F marked "IN" in. Fig.6 (suction connection). Then remove the cap using a screwdriver.

Make the connection at output from the system through the mouth on Face F marked "OUT" in Fig.6 (delivery connection). Then remove the cap using a screwdriver.

All the hydraulic connections of the system to the plant to which it can be connected are of the threaded female type 1" GAS, made of brass.

If you intend to connect the product to the plant with fittings that have a diameter larger than the normal 1" pipe (for example the ring nut in the case of fittings in 3 pieces), make sure that the 1" Gas male thread of the coupling protrudes at least 25mm from the above diameter (see Fig.7)

ENGLISH

Figure 7

The brass threads are housed in technopolymer seats. When making the connection watertight by adding material (e.g. Teflon, hemp,...) ensure that the gasket is not too thick: under the action of an adequate tightening torque (e.g. long handled pipe wrench), the excess material could exert abnormal force on the technopolymer seat, damaging it irremediably.

With reference to its position with respect to the water to be pumped, the installation of the system may be defined "above head" or "below head". In particular the installation is defined "above head" when the pump is placed at a level higher than the water to be pumped (e.g. pump on the surface and water in a well); vice versa it is "below head" when the pump is placed at a level lower than the water to be pumped (e.g. overhead cistern and pump below).

If the vertical installation of the system is of the "over head" type, it is recommended to fit a non-return valve in the suction section of the system; this is to allow the operation of loading the system (par. 2.1.2).

If the installation is of the "over head" type, install the suction pipe from the water source to the pump in such a way as to avoid the formation of goosenecks or siphons. Do not place the suction pipe above the pump level (to avoid the formation of air bubbles in the suction pipe). The suction pipe must draw at its entrance at a depth of at least 30cm below the water level and must be watertight along its whole length, as far as the entrance to the electropump.

The suction and delivery pipes must be fitted so that they do not exert any mechanical pressure on the pump.

2.1.2. Loading Operation - Installation above head and below head

Installation "above head" (par. 2.1.1): access the technical compartment and, using a screwdriver, remove the filling cap (Fig.3). Fill the system with clean water through the loading door, taking care to let the air out. If the non-return valve on the suction pipe (recommended in paragraph 2.1.1) has been placed close to the system entry door, the quantity of water with which to fill the system should be 0,9 litres. It is recommended to fit the non-return valve at the end of the suction pipe (foot valve) so as to be able to fill it quickly too during the loading operation. In this case the quantity of water necessary for the loading operation will depend on the length of the suction pipe (0,9 litres + ...).

Installation "below head" (par. 2.1.1): if there are no check valves between the water deposit and the system (or if they are open), it loads automatically as soon as it is allowed to let out the trapped air. So slackening the filling cap (Fig.3) enough to vent the trapped air allows the system to load completely. You must survey the operation and close the loading door as soon as the water comes out (however it is recommended to fit a check valve in the section of the suction pipe and to use it to control the loading operation with the cap open). Alternatively, in the case where the suction pipe is intercepted by a closed valve, the loading operation may be carried out in a similar way to the one described for installation over head.

2.2 - Horizontal Configuration

Screw the 4 rubber feet supplied loose in the package into the brass seats in face E. Put the system in place, taking into account the dimensions in Fig.8.

• The distance of at least 10mm between Face B of the system and an obstruction is obligatory to let out the power supply cable to the mains socket.
• The distance of at least 200mm between Face A of the system and an obstruction is recommended so as to be able to remove the door and gain access to the technical compartment.

If the surface is not flat, unscrew the foot that is not touching and adjust its height until it contacts the surface so as to ensure the stability of the system. The system must in fact be placed in a safe and stable position, ensuring that its axis is vertical: it must not be in an inclined position.

2.2.1 Hydraulic connections

Make the connection at input to the system through the mouth on Face C marked "IN" in Fig. 8 (suction connection). Then remove the cap using a screwdriver. Make the connection at output from the system through the mouth on Face C marked "OUT 1" in Fig. 8 and/or through the mouth on Face F marked "OUT 2" in Fig. 8 (delivery connection).

In this configuration either of the 2 mouths can be used as an alternative to the other (depending on the convenience of the installation), or simultaneously (dual delivery system). Then remove the cap(s) from the door(s) you intend to use with a screwdriver.

All the hydraulic connections of the system to the plant to which it can be connected are of the threaded female type 1" GAS, made of brass.

See WARNING for Fig.7.

• Disengage the 4 screws at the corners of the panel using the accessory tool.
• Do not remove the screws completely, just disengage them from the thread on the product body.
• Be careful not to drop the screws into the system.
• Move the panel away, taking care not to pull on the signal transmission cable.
• Reposition the panel in its seat at the preferred angle taking care not to pinch the cable.

Tighten the 4 screws with the wrench.

2.2.3 Loading Operation - Installation above head and below head

With reference to its position with respect to the water to be pumped, the installation of the system may be defined "above head" or "below head". In particular the installation is defined "above head" when the pump is placed at a level higher than the water to be pumped (e.g. pump on the surface and water in a well); vice versa it is "below head" when the pump is placed at a level lower than the water to be pumped (e.g. overhead cistern and pump below).

Installation “above head”: with a screwdriver, remove the filling cap which, for the horizontal configuration, is the one on Face F (Fig.1). Fill the system with clean water through the loading door, taking care to let the air out: to ensure optimum filling it is convenient to open also the loading door on Face A (Fig.1), used for filling in the vertical configuration, so as to let all the air out, which otherwise could remain trapped in the system; take care to close the openings correctly once the operation is completed. The quantity of water with which to fill the system must be at least 0,7 litri almeno. litres. It is recommended to fit a non-return valve at the end of the suction pipe (foot valve) so as to be able to fill it quickly too during the loading operation. In this case the quantity of water necessary for the loading operation will depend on the length of the suction pipe (0,7 litres + ...).

Installation "below head": if there are no check valves between the water deposit and the system (or if they are open), it loads automatically as soon as it is allowed to let out the trapped air. So slackening the filling cap (Face F - Fig.1) enough to vent the air allows the system to load completely. You must survey the operation and close the loading door as soon as the water comes out (however it is recommended to fit a check valve in the section of the suction pipe and to use it to control the loading operation with the cap loose). Alternatively, in the case where the suction pipe is intercepted by a closed valve, the loading operation may be carried out in a similar way to the one described for installation over head.

3. COMMISSIONING

The suction depth must not exceed 8 m.

3.1 Electrical Connections

To improve immunity to the possible noise radiated towards other appliances it is recommended to use a separate electrical duct to supply the product.

The line voltage may change when the electropump is started. The line voltage may undergo variations depending on other devices connected to it and on the quality of the line.

It is recommended to carry out installation as indicated in the manual, in compliance with the laws, directives and standards in force in the place of use and depending on the application.

The product contains an inverter inside which there are continuous voltages and currents with high-frequency components (see Table 2).

3.2 Configuration of the Integrated Inverter

The system is configured by the manufacturer to satisfy most installation cases operating at constant pressure. The main parameters set in the factory are:

• Set-Point (desired value of constant pressure) SP = 2.7 bar / 39 psi.
  • Reduction of pressure to restart RP = 0.3 bar / 4.3 psi.
• Anti-cycling function: Disabilitata.

However, these parameters and others can be set by the user according to the system. See par. 4-5 for the specifications.

For the definition of the parameters SP and RP, the pressure at which the system starts has the value:

Pstart = SP - RP For example: 2.7 - 0.3 = 2.4 bar in the default configuration

The system does not work if the utility is at a height higher than the equivalent in metres of water column of the Pstart (consider 1 bar = 10 m water column): for the default configuration, if the utility is at a height of at least 27m the system does not start.

3.3 - Priming

The priming of a pump is the phase during which the machine attempts to fill the body and the suction pipe with water. If the operation is successful the machine can work regularly.

ENGLISH

Once the pump has been filled (par. 2.1.2, 2.2.3) and the device has been configured (par. 3.2), it is possible to connect the electric power supply after having opened at least one utility on delivery for the first 10 seconds.

If a flow of water is detected in delivery, the pump is primed and starts its regular work. This is the typical case of installation below head (par. 2.1.2, 2.2.3). The utility opened in delivery from which the pumped water is coming out can be closed.

If a regular flow in delivery is not detected after 10 seconds, the system asks for confirmation to enter the priming procedure (typical case of installation above head par. 2.1.2, 2.2.3). Or:

Fill the pump Escape First priming

Figure 11.1: Priming PopUp ^(1)

Fill the pump Escape First priming

Figure 11.2: Priming PopUp (2)

When “A” is pressed the pump enters the priming procedure: it starts working for a maximum time of 5 minutes during which the safety block for dry operation is not tripped. The priming time depends on various parameters, the most influential of which are the depth of the water level from which it is drawing, the diameter of the suction pipe, the water-tightness of the suction pipe. On condition that a suction pipe is used that is no smaller than 1” and that it is well sealed (with no holes or joins from which it can take in air), the product has been studied to manage to prime in water conditions up to 8m in depth in a time of less than 5 minutes. As soon as the product detects a regular flow in delivery, it leaves the priming procedure and starts its regular work. The utility opened in delivery from which the pumped water is coming out can be closed. If after 5 minutes of the procedure the product is still not primed, the interface display sends a failure message. Disconnect the power supply, load the product adding new water, wait 10 minutes and repeat the procedure from the moment you put the plug in the socket.

Press "v" to confirm that you do not want to start the priming procedure. The product remains in alarm status.

Operation

Once the electropump is primed, the system starts regular operation according to the configured parameters: it starts automatically when the tap is turned on, supplies water at the set pressure (SP), keeps the pressure constant even when other taps are turned on, stops automatically after time T2 once the switching off conditions are reached (T2 can be set by the user, factory value 10 sec).

4. THE KEYPAD AND THE DISPLAY

The user interface is composed of a keypad with 320x240 pixel LCD display and with POWER, COMM, ALARM warning leds as can be seen in Fig.12.

The display shows the values and the statuses of the device, with indications on the functionality of the various parameters.

The functions of the keys are summed up in Table 5.

DAB MODE SET

Figure 12

	The MODE key allows you to move on to the next items in the same menu. Holding it down for at least 1 sec allows you to skip to previous menu item.
	The SET key allows you to leave the current menu.
	Decreases the current parameter (if it is an editable parameter).

ENGLISH

Increases the current parameter (if it is an editable parameter).

Table 5

Holding down the “^” key or the “v” key allows the automatic increase/decrease of the parameter selected. After the “^” key or the “v” key has been held down for 3 seconds, the automatic increase/decrease speed increases.

When the ^ key or the v key is pressed the selected value is modified and saved immediately in the permanent memory (EEprom). If the machine is switched off, even accidentally, in this phase it does not cause the loss of the parameter that has just been set. The SET key is only for leaving the current menu and is not necessary for saving the changes made. Only in particular cases described in the following paragraphs are some values updated by pressing "SET" or "MODE".

Warning leds

• Power
  White led. Lit with a fixed light when the machine is powered. Blinking when the machine is disabled.
• Alarm
  Red led. Lit with a fixed light when the machine is blocked by an error.

Menus

The complete structure of all the menus and of all the items of which they are composed is shown in Table 7.

Access to the menus

The various menus can be accessed from the main menu in two ways:

1. Direct access with a combination of keys.
2. Access by name with a drop-down menu.

4.1 Direct Access with a Combination of Keys

The desired menu can be accessed directly by pressing simultaneously the appropriate combination of keys for the required time (for example MODE SET to enter the Setpoint menu) and the various items in the menu are scrolled with the MODE key.

4.5 - Blocking parameter setting by Password

The device has a password-enabled protection system. If a password is set, the parameters of the device will be accessible and visible but it will not be possible to change them. The password management system is in the “technical assistance” menu and is managed by means of the parameter PW.

4.6 - Enabling and disabling the motor

In normal operating conditions, pressing and then releasing both the “A” and “V” keys causes the blocking/release of the motor (self-holding even after switching off). If there is a fault alarm, the operation described above resets the alarm. When the motor is disabled this status is shown by the blinking white LED. This command can be activated from any menu page except RF and PW.

5. MEANING OF THE INDIVIDUAL PARAMETERS

The inverter makes the system work at constant pressure. This regulation is appreciated if the hydraulic plant downstream from the system is suitably sized. Plants made with pipes with too small a section introduce load losses that the equipment cannot compensate; the result is that the pressure is constant on the sensors but not on the utility.

Plants that are excessively deformable can create the onset of oscillations; if this occurs, the problem can be solved by adjusting the control parameters "GP" and "GI" (see par 5.6.3 - GP: Proportional gain coefficient and 5.6.4 - GI: Integral gain coefficient)

5.1 User Menu

From the main menu, hold down simultaneously the "MODE" and "SET" keys until "SP" appears on the display (or use the selection menu pressing ∧ or ∨). The ∧ and ∨ keys allow you respectively to increase and decrease the plant boosting pressure.

Press SET to leave this menu and return to the main menu. The range of adjustment is 1-5.5 bar (14-80 psi).

5.3.1 - SP: Setting the setpoint pressure

Pressure at which the system is pressurised.

The pump restarting pressure is linked not only to the set pressure SP but also to RP. RP expresses the decrease in pressure, with respect to “SP” caused by the pump starting.

For example: SP = 3,0 [bar]; RP = 0,3 [bar];

During normal operation the system is pressurised at 3.0 [bar].

The electropump restarts when the pressure falls belowai 2,7 [bar].

Setting a pressure (SP) that is too high for the pump performance may cause false water lack errors BL; in these cases lower the set pressure.

5.4 - Manual Menu

In manual operation, the sum of the input pressure and the maximum pressure that can be supplied must not be greater than 6 bar.

From the main menu, hold down simultaneously the "SET" and "^" and "v" keys until the manual menu page appears (or use the selection menu pressing ^ or v). Press SET to leave this menu and return to the main menu. Entering the manual menu by pressing the SET ^ v keys puts the machine into forced STOP condition. This function can be used to force the machine to stop. In the main menu, irrespective of the parameter displayed, it is always possible to perform the following controls:

Temporary starting of the electropump.

Pressing the MODE and ^ keys at the same time causes the pump to start at speed RI and this running status remains as long as the two keys are held down. When the pump ON of pump OFF command is given, a communication appears on the display.

Starting the pump

Holding down the MODE v ^ keys simultaneously for 2 sec. causes the pump to start at speed RI. The running status remains until the SET key is pressed. The next time the SET key is pressed the pump leaves the manual menu. When the pump ON of pump OFF command is given, a communication appears on the display. In case of operation in this mode for more than 5' with no flow of liquid, an alarm overheating alarm will

ENGLISH

be triggered, with the error PH shown on the display. Once the PH error condition is no longer present, the alarm will be reset automatically only. The reset time is 15'; if the PH error occurs more than 6 times consecutively, the reset time increases to 1h. Once it has reset further to this error, the pump will remain in stop status until the user restarts it using the "MODE" "v" "^" keys.

5.4.1 - Status

Indicates the range of supply voltage found. It may have the values: [110-127] V or [220-240] V. If the range is not determined, it has the value “- -”.

5.4.10 - TE: Dissipator temperature display

5.5 - Installer Menu

From the main menu, hold down simultaneously the "MODE" and "SET" and "v" keys until the first parameter of the installer menu appears on the display (or use the selection menu pressing ∧ or ∨). The menu allows you to view and modify various configuration parameters: the MODE key allows you to scroll through the menu pages, the ∧ and ∨ keys allow you respectively to increase and decrease the value of the parameter concerned. Press SET to leave this menu and return to the main menu.

5.5.1 - RP: Setting the pressure fall to restart

Expresses the fall in pressure with respect to the SP value which causes. Restarting of the pump.

For example if the setpoint pressure is 3.0 [bar] and RP è 0.5 [bar] the pump will restart at 2.5 [bar]. RP can be set from a minimum of 0.1 to a maximum of 1 [bar]. In particular conditions (for example in the case of a setpoint lower than the RP) it may be limited automatically. To assist the user, on the RP setting page the actual restarting pressure also appears highlighted under the RP symbol, see Fig. 18.1-18.2.

5.5.2 - OD: Type of plant

Possible values 1 and 2 referring to a rigid system and an elastic system.

The device leaves the factory with mode 1 suitable for the majority of systems. In the presence of swings in pressure that cannot be stabilised by adjusting the parameters GI and GP, change to mode 2.

ENGLISH

IMPORTANT: The regulating parameters GP and GI also change in the two configurations. In addition the GP and GI values set in mode 1 are stored in a different memory from the GP and GI values set in mode 2. So, for example, when passing to mode 2, the GB value of mode 1 is replaced by the GB value of mode 2 but it is kept and will reappear again when returning to mode 1. The same value shown on the display has a different weight in one mode or in the other because the control algorithm is different.

5.5.3 - MS: Measuring system

Set the measuring system, choosing between metric and Anglo-American units. The quantities displayed are shown in Table 13.

Sets the time when the inverter switches off after detecting low pressure on suction (see Setting low pressure detection on suction par. 5.7).

T1 can be set between 0 and 12 s. The factory setting is 2 s.

5.6 - Technical Assistance Menu

Present only in models with Kiwa function.

Advanced settings to be made only by skilled personnel or under the direct control of the service network.

From the main menu, hold down simultaneously the "MODE" and "SET" keys until "SP" appears on the display (or use the selection menu pressing ∧ or ∨). The menu allows you to view and modify various configuration parameters: the MODE key allows you to scroll through the menu pages, the ∧ and ∨ keys allow you respectively to increase and decrease the value of the parameter concerned. Press SET to leave this menu and return to the main menu.

5.6.1 - TB: Water lack blockage time

Setting the reaction time of the water lack blockage allows you to select the time (in seconds) taken by the device to indicate the lack of water. The variation of this parameter may be useful if there is known to be a delay between the moment the motor is switched on and the moment it actually begins to deliver. One example may be a plant where the suction pipe is particularly long and there are some slight leaks. In this case the pipe in question may be discharged and, even though water is not lacking, the electropump will take a certain time to reload, supply the flow and put the plant under pressure.

5.6.2 - T2: Delay in switching off

Sets the delay with which the inverter must switch off after switch-off conditions have been reached: plant under pressure and flow rate lower than the minimum flow. T2 can be set between 2 and 120 s. The factory setting is 10 s.

5.6.3 - GP: Proportional gain coefficient

Generally the proportional term must be increased for systems characterised by elasticity (for example with PVC pipes) and lowered in rigid systems (for example with iron pipes).

To keep the pressure in the system constant, the inverter performs a type PI control on the measured pressure error. Depending on this error the inverter calculates the power to be supplied to the motor. The behaviour of this control depends on the set GP and GI parameters. To cope with the different behaviour of the various types of hydraulic plants where the system can work, the inverter allows the selection of parameters different from those set by the factory. For nearly all plants the factory-set GP and GI parameters are optimal. However, should any problems occur in adjustment, these settings may be varied.

ENGLISH

5.6.4 - Gl: Integral gain coefficient

In the presence of large falls in pressure due to a sudden increase of the flow or a slow response of the system, increase the value of GI. Instead, if there are swings in pressure around the setpoint value, decrease the value of GI.

IMPORTANT: To obtain satisfactory pressure adjustments, you generally have to adjust both GP and GI.

5.6.5 - RM: Maximum speed

Sets a maximum limit on the number of pump revolutions.

5.6.6 - AY: Anti Cycling

As described in paragraph 9, this function is for avoiding frequent switching on and off in the case of leaks in the system. The function can be enabled in 2 different modes, normal and smart. In normal mode the electronic control blocks the motor after N identical start/stop cycles. In smart mode it acts on the parameter RP to reduce the negative effects due to leaks. If set on "Disable", the function does not intervene.

5.6.7 - AE: Enabling the anti-block function

This function is for avoiding mechanical blocks in the case of long inactivity; it acts by periodically rotating the pump.

When the function is enabled, every 23 hours the pump performs an unblocking cycle lasting 1 min.

5.6.8 - AF: Enabling the anti-freeze function

If this function is enabled the pump is automatically rotated when the temperature reaches values close to freezing point, in order to avoid breakages of the pump.

5.7- Setting low pressure detection on suction (typically used in boosting systemsconnected to the water mains)

Present only in models with Kiwa function.

The low pressure detecting function generates the blocking of the system after the time T1 (see 5.5.6 - T1: Low pressure delay).

When this function is active the symbol F4 is shown on the main page.

Tripping of this function causes the pump to cut out; it may be reset automatically or manually. The automatic reset requires that, to leave the error condition F4, the pressure must return to a value 0.3 bar higher than PK for at least 2 sec. To reset the cut-out in manual mode, press and then release the “^” and “v” keys simultaneously.

5.8 - RF: Fault and warning reset

Holding down the ∧ and ∨ keys together for at least 2 seconds deletes the history of faults and warnings. The number of faults present in the log is indicated under the symbol RF (max 64). The log can be viewed from the MONITOR menu on page FF.

5.8.1 - PW: Change password

The device has a password-enabled protection system. If a password is set, the parameters of the device will be accessible and visible but it will not be possible to change them.

When the password (PW) is "0" all the parameters are unlocked and can be edited. When a password is used (value of PW different from 0) all modifications are blocked and "XXXX" is displayed on the page PW.

If the password is set it allows to navigate through all the pages, but at any attempt to edit a parameter a pop-up appears, asking you to type in the password. When the correct password is typed in the parameters are unlocked and can be edited for 10' after the last key is pressed. If you want to cancel the password timer, just go to page PW and hold down ^ and v together for 2". When the correct password is typed in a padlock is shown opening, while if the wrong password is given a flashing padlock appears. After resetting the factory values the password is set back at "0".

Each change of the password takes effect when Mode or Set is pressed and each subsequent change of a parameter implies typing in the new password again (e.g. the installer makes all the settings with the default PW value = 0 and lastly sets the PW so as to be sure that the machine is already protected without any further action).

If the password is lost there are 2 possibilities for editing the parameters of the device:

• Make a note of the values of all the parameters, reset the device with the factory values, see paragraph 7.3. The reset operation cancels all the parameters of the device, including the password.
• Make a note of the number present on the password page, send a mail with this number to your service centre, in a few days you will be sent the password to unlock the device.

6. PROTECTION SYSTEMS

The device is equipped with protection systems to preserve the pump, the motor, the supply line and the inverter. If one or more protections trip, the one with the highest priority is immediately notified on the display. Depending on the type of error the motor may stop, but when normal conditions are restored the error status may be cancelled immediately or only after a certain time, following an automatic reset.

In the case of blockage due to water lack (BL), blockage due to motor overload (OC), blockage due to direct short circuit between the motor phases (SC), you can try to exit the error conditions manually by simultaneously pressing and releasing the and keys. If the error condition remains, you must take steps to eliminate the cause of the fault.

In the event of blocking due to one of the internal errors E18, E19, E20, E21 it is necessary to wait 15 minutes with the machine powered until the blocked status is automatically reset.

Table 16: Indications of blockages

6.1 - Description of blockages

6.1.1 - "BL" Anti Dry-Run (Protection against dry running)

In the case of lack of water the pump is stopped automatically after the time TB. This is indicated by the red “Alarm” led and by the letters “BL” on the display. After having restored the correct flow of water you can try to leave the protective block manually by pressing the “^” and “v” keys simultaneously and then releasing them. If the alarm status remains, or if the user does not intervene by restoring the flow of water and resetting the pump, the automatic restart will try to restart the pump.

If the parameter SP is not correctly set, the protection against water lack may not work correctly.

6.1.2 - Anti-Cycling (Protection against continuous cycles without utility request)

If there are leaks in the delivery section of the plant, the system starts and stops cyclically even if no water is intentionally being drawn: even just a slight leak (a few ml) can cause a fall in pressure which in turn starts the electropump.

The electronic control of the system is able to detect the presence of the leak, based on its recurrence.

The Anti-Cycling function can be excluded or activated in Basic or Smart mode (par 5.6.6).

In Basic mode, once the condition of recurrence is detected the pump stops and remains waiting to be manually reset. This condition is communicated to the user by the lighting of the red "Alarm" led and the appearance of the word "ANTICYCLING" on the display. After the leak has been removed, you can manually force restart by simultaneously pressing and releasing the "^" and "v" keys.

In Smart mode, once the leak condition is detected, the parameter RP is increased to decrease the number of starts over time.

6.1.3 - Anti-Freeze (Protection against freezing of water in the system)

The change of state of water from liquid to solid involves an increase in volume. It is therefore essential to ensure that the system does not remain full of water with temperatures close to freezing point, to avoid breakages of the system. This is the reason why it is recommended to empty any electropump that is going to remain unused during the winter. However, this system has a protection that prevents ice formation inside by activating the electropump when the temperature falls to values close to freezing point. In this way the water inside is heated and freezing prevented.

ENGLISH

The Anti-Freeze protection works only if the system is regularly fed: with the plug disconnected or in the absence of current the protection cannot work.

However, it is advised not to leave the system full during long periods of inactivity: drain the system accurately through the drainage cap and put it away in a sheltered place.

6.1.4 - "BP1" Blockage due to fault of the delivery pressure sensor (system pressurisation)

If the device detects a fault in the delivery pressure sensor the pump remains blocked and the error signal "BP1" is given. This status begins as soon as the problem is detected and ends automatically when correct conditions have been restored.

6.1.5 - "BP2" Blockage due to fault of the suction pressure sensor

If the device detects a fault in the suction pressure sensor the pump remains blocked and the error signal "BP2" is given. This status begins as soon as the problem is detected and ends automatically when correct conditions have been restored.

6.1.6 - "PB" Blockage due to supply voltage outside specifications

This occurs when the allowed line voltage at the supply terminal assumes values outside the specifications. It is reset only automatically when the voltage at the terminal returns within the allowed values.

6.1.7 - "SC" Blockage due to short circuit between the motor phases

The device is provided with protection against the direct short circuit which may occur between the motor phases. When this blockage is indicated you can attempt to restore operation by simultaneously holding down the and keys, but this will not have any effect until 10 seconds have passed since the moment the short circuit occurred.

6.2 - Manual reset of error conditions

In error status, the user can cancel the error by forcing a new attempt, pressing and then releasing the ∧ and ∨ keys.

6.3 - Self-reset of error conditions

For some malfunctions and blockage conditions, the system attempts automatic self-reset.

The auto self-reset procedure concerns in particular:

"BL" Blockage due to water lack

"PB" Blockage due to line voltage outside specifications (1)

"OT" Blockage due to overheating of the power stages

"OC" Blockage due to motor overload (1)

"BP1" Blockage due to fault of the pressure sensor

"BP2" Blockage due to fault of the Kiwa pressure sensor

For example, if the system is blocked due to water lack, the device automatically starts a test procedure to check whether the machine is really left definitively and permanently dry. If during the sequence of operations an attempted reset is successful (for example, the water comes back), the procedure is interrupted and normal operation is resumed.

Table 13 shows the sequences of the operations performed by the device for the different types of blockage..

Automatic resets of error conditions
Display indication	Description	Automatic reset sequence
BL Blockage due to water lack	- One attempt every 10 minutes for a total of 6 attempts.- One attempt every hour for a total of 24 attempts- One attempt every 24 hours for a total of 30 attempts.
PB(1)	Blockage due to line voltage outside specifications	- It is reset when it returns to a specific voltage.
OT	Blockage due to overheating of the power stages	- It is reset when the temperature of the power stages returns within the specifications.
OC(1) Blockage due to motor overload	- One attempt every 10 minutes for a total of 6 attempts.- One attempt every hour for a total of 24 attempts.- One attempt every 24 hours for a total of 30 attempts.

7. RESET AND FACTORY SETTINGS

7.1 General system reset

To reset the system, hold down the 4 keys simultaneously for 2 sec. This operation is the same as disconnecting the power, waiting for it to close down completely and supplying power again. The reset does not delete the settings saved by the user.

7.2 Factory settings

The device leaves the factory with a series of preset parameters which may be changed according to the user's requirements. Each change of the settings is automatically saved in the memory and, if desired, it is always possible to restore the factory conditions (see Restoring the factory settings par 7.3 - Restoring the factory settings).

7.3 Restoring the factory settings

To restore the factory values, switch off the device, wait until the display has switched off completely, press and hold down the "SET" and "^" keys and turn on the power; release the two keys only when the letters "EE" appear. This restores the factory settings (a message and a rereading on EEPROM of the factory settings permanently saved in the FLASH memory). Once all the parameters have been set, the device returns to normal operation.

NOTE: Once the factory values have been restored it will be necessary to reset all the parameters that characterise the system (gains, setpoint pressure, etc.) as at the first installation.

9. PARTICULAR INSTALLATIONS

9.1 - Inhibiting self-priming

The product is made and supplied with the capacity of being self-priming. With reference to par. 2.1.2, the system is able to prime and therefore operate in whatever installation configuration chosen: below head or above head. However there are cases in which the self-priming capacity is not necessary, or areas where it is forbidden to use self-priming pumps. During priming the pump obliges part of the water already under pressure to return to the suction part until a pressure value is reached at delivery whereby the system can be considered primed. At this point the recirculating channel closes automatically. This phase is repeated each time the pump is switched on, even already primed, until the same pressure value that closes the recirculating channel is reached (about 1 bar).

When the water arrives at the system intake already under pressure (maximum allowed 2 bar) or when the installation is always below head, it is possible (and mandatory where local regulations require it) to force the closure of the recirculating pipe, losing the self-priming capacity. This obtains the advantage of eliminating the clicking noise of the pipe shutter each time the system is switched on. To force closure of the self-priming pipe, proceed as follows:

1. Disconnect the power supply;
2. empty the system (unless you decide to inhibit self-priming at the first installation);
3. remove the drainage cap on Face E, taking care not to drop the O-Ring (Fig.19);
4. with the aid of pliers take the shutter out of its seat. The shutter will be extracted together with the O-Ring and the metal spring with which it is assembled;
5. remove the spring from the shutter; insert the shutter in its seat again with the respective O-Ring (side with gasket towards the inside of the pump, stem with cross-shaped fins towards the outside);
6. screw on the cap after having positioned the metal spring in side so that it is compressed between the cap itself and the with cross-shaped fins of the shutter stem. When repositioning the cap ensure that the respective O-Ring is always correctly in its seat;
7. fill the pump, connect the power supply, start the system.

10. MAINTENANCE

Disconnect the power supply before starting any work on the system.

ENGLISH

The system requires no routine maintenance operations.

However, below are the instructions for performing the special maintenance operations that may be necessary in particular cases (e.g. emptying the system to put it away during a period of inactivity).

10.1 Accessory tool

With the product, DAB supplies a metal key with a hexagonal section (Fig.21) useful for performing some special maintenance operations on the system, or during installation.

In particular, use the key for the orientation of the interface panel described in par. 2.2.2 or for opening the door of the compartment next to the interface panel. If the key is lost or damaged, the operation can be done using a standard 2mm allen wrench.

Figure 21

10.2 - Emptying the system

If you want to drain the water out of the system, proceed as follows:

1. disconnect the power supply;
2. turn on the delivery tap closes to the system so as to remove pressure from the system and empty it as much as possible;
3. if there is a check valve immediately downstream from the system (always recommended), close it so as not to let out the water that is in the plant between the system and the first turned on tap;
4. interrupt the suction pipe in the point closest to the system (it is always recommended to have a check valve immediately upstream from the system) so as not to drain the whole suction system;
5. remove the drainage cap Fig.1 face E if vertical configuration; Fig.1 Face C if horizontal configuration) and let out the water inside (about 1.5 litres);
6. the water that is trapped in the delivery system downstream from the non-return valve integrated in the system can flow out at the time of disconnecting the system, or on removing the cap of the second delivery (if not used).

Though essentially drained, the system is unable to expel all the water that it contains. During handling of the system after emptying it, some small amounts of water may probably leak out from the system.

10.3 - Non-return valve

The system has an integrated non-return valve which is necessary for correct operation. The presence of solid bodies or sand in the water could cause malfunctioning of the valve and therefore of the system. Although it is recommended to use fresh water and eventually fit filters on input, if you notice abnormal operation of the non-return valve it can be extracted from the system and cleaned and/or replaced by proceeding as follows:

1. remove the access door to the special maintenance compartment (Fig.1 Face F) disengaging the 2 fixing screws with the accessory tool. It is advisable not to remove the screws completely, so that you can used them to extract the door. Take care not to drop the screws inside the system once you have removed the door (Fig.22);
2. using a screwdriver, remove the 1"1/4 cap so as to access the non-return valve (Fig.22);
3. using pliers, extract the cartridge of the non-return valve without rotating it, gripping it by the jumper provided for the purpose (Fig.22): the operation may require a certain effort;
4. clean the valve under running water, ensure that it is not damaged and replace it if necessary;
5. put the complete cartridge back in its seat: the operation requires the force necessary to compress the 2 O-Rings (Fig.22);
6. Screw on the 1"1/4 cap until it is snug: if the cartridge has not been pushed correctly in place, screwing on the cap will complete its positioning (Fig.22);
7. reposition the door and tighten the 2 screws (Fig.22).

Figure 22

Should one or more O-rings be lost or damaged during maintenance operations on the non-return valve, they must be replaced. Otherwise the system might not work correctly.

ENGLISH

10.4 - Motor shaft

The electronic control of the system ensures smooth starts so as to avoid excessive stress on the mechanical parts and thus prolong the life of the product. In exceptional cases this characteristic could cause problems in starting the pump: after a period of inactivity, perhaps with the system drained, the salts dissolved in the water could have settled and formed calcification between the moving part (motor shaft) and the fixed part of the pump, thus increasing the resistance on starting. In this case it may be sufficient to help the motor shaft by hand to detach itself from the calcifications. In this system the operation is possible because access to the motor shaft from outside is guaranteed and a groove is provided at the end of the shaft. Proceed as follows:

1. remove the cover of the technical compartment (Fig. 1 Face A);
2. lift the rubber cover of the motor shaft access cap (Fig. 23);
3. using a 10mm hexagonal key, remove the motor shaft access cap (Fig. 23);
4. insert a straight tip screwdriver in the groove on the motor shaft and manoeuvre, turning in 2 directions (Fig. 23);
5. if it is turning freely the system can be started, after having replaced the cap and cover that have been removed;
6. if rotation is blocked and it cannot be removed by hand, call the assistance service.

10.5 - Expansion Vessel

See paragraph 1.2 for the operations to check and adjust the air pressure in the expansion vessel and to replace it if it is broken.

To access the valve of the expansion vessel, proceed as follows:

1. remove the access door to the special maintenance compartment (Fig.1 Face F) disengaging the 2 fixing screws with the accessory tool. It is advisable not to remove the screws completely, so that you can used them to extract the door. Take care not to drop the screws inside the system once you have removed the door (Fig. 24);
2. slip the rubber cap off the valve or the expansion vessel (Fig. 24);
3. regulate the valve as indicated in paragraph 1.2 (Fig. 24);
4. reposition the rubber cap (Fig. 24);
5. reposition the door and tighten the 2 screws (Fig. 24).
