 The power supply line is provided with:

- A high-sensitivity differential switch (30 mA) [residual current device RCD] suitable for earth fault currents with DC or pulsating DC content (a Type B RCD is suggested).

- A mains isolator switch with a contact gap of at least 3 mm.

The electrical control panel checklist

Check that the following requirements are met:  The control panel must protect the pump against short-circuit. A time lag fuse or a circuit

breaker (Type C model is suggested) can be used to protect the pump.

 The pump has built in overload and thermal protection, no additional overload protection is

required.

Grounding (earthing)

Use a cable with several strands to reduce electric noise.

Parameter

Unit of measurement

Description

P25

Control mode [ACT, HCS, MSE, MSY]

This parameter sets the Control Mode (default value: HCS)

ACT

: Actuator mode. A single pump maintains a fixed speed at any flow rate. ACT will always try to minimize the difference between the speed setpoint and the actual rotational speed of the motor. If a 0-10V signal is supplied to terminals 7 and 8, the pump automatically switches to ACT mode, following the external signal, as shown in figure 17. If the external signal is missing, the pump remains in ACT mode, using the value set as setpoint using the display.

HCS

: Hydrovar® Controller mode for Single pump. The pump maintains a constant pressure at any flow rate: the Hydrovar® algorithm, based on the set of parameters from P26 to P37 (see Par. 6.5.3), is implemented. HCS mode must be set in conjunction with the use of an absolute reading pressure sensor installed in the hydraulic circuit, which

6.5.2 Settings Parameters

6.5.3 Drive Configuration Parameters

Depending on the type of pump used

Page 33

en – Original instructions

supplies to the unit the pressure feedback signal: HCS will always try to minimize the difference between the pressure setpoint and the pressure feedback signal.

MSE

: Hydrovar® Controller mode for multiple pumps in Serial Cascade. Pumps are managed in series: only the last activated pump modulates the speed to maintain the set pressure, while all the others in operation rotate at the maximum speed. The set of pumps, connected to each other through the multi-pump protocol, maintains a constant pressure at any flow rate: the Hydrovar® algorithm, based on the set of parameters from P26 to P37 (see Par. 6.5.3), is implemented. MSE mode must be set in conjunction with the use of absolute reading pressure sensors, one for each pump, which supply to the set the pressure feedback signal: MSE will always try to minimize the difference between the pressure setpoint and the pressure feedback signal. Using the multi-pump protocol, it is possible to connect up to 3 pumps, all of the same type and with the same power.

MSY

: Hydrovar® Controller mode for Multiple pumps in Synchronous Cascade. The pumps are synchronised: they all keep the set pressure and operate at the same speed. Other characteristics: as for MSE mode.

P26

Max RPM set [ACT set-Max*]

rpmx10

Maximum pump speed setup.

P27

Min RPM set [Min*-ACT set]

P28

Ramp 1 [1-250]

This parameter adjusts the fast acceleration time. It affects the control of the pump for HCS, MSE and MSY control modes (also see Par. 6.6.2). Default: 3 s.

P29

Ramp 2 [1-250]

This parameter adjusts the fast deceleration time It affects the control of the pump for HCS, MSE and MSY control modes (also see Par. 6.6.2). Default: 3 s.

P30

Ramp 3 [1-999]

This parameter adjusts the slow acceleration. It determines:

 The Hydrovar®adjustment speed, in case of small flow rate

variations

 The constant outgoing pressure.

The ramp depends on the system being controlled, and affects the control of the pump in HCS, MSE and MSY modes (also see Par. 6.6.2). Default: 35 s.

P31

Ramp 4 [1-999]

Adjustment of the slow deceleration time (also see Par. 6.6.2). Other characteristics: as for Ramp 3.

P32

Ramp Speed Min Acceleration [2.0-

25.0]

This parameter sets the fast acceleration time. It represents the acceleration ramp used by the Hydrovar® controller until the minimum speed of the pump is reached (P27). It affects the control of the pump for HCS, MSE and MSY control modes (also see Par. 6.6.2). Default: 2.0 s.

Depending on the type of pump used

Page 34

en – Original instructions

P33

Ramp Speed Min Deceleration [2.0-

25.0]

This parameter sets the fast deceleration time. It represents the deceleration ramp used by the Hydrovar® controller for stopping the pump once the minimum speed of the pump is reached (P27). It affects the control of the pump for HCS, MSE and MSY control modes (also see Par. 6.6.2). Default: 2.0 s.

P34

Speed Min Configuration [STP, SMI]

This parameter defines the operation of the Hydrovar® controller once the minimum speed of the pump is reached (P27):



STP

(STP): once the required pressure is reached and no further request is made, the pump speed decreases to the selected P27 value: Hydrovar® then keeps running for the selected time interval (P35), and then stops automatically.



SNI

(SMI): once the required pressure is reached and no further request is made, the pump speed decreases to the selected P27 value: Hydrovar® continues running at the same speed. This parameter affects the control of the pump for HCS, MSE and MSY control modes.

Default: STP

P35

Smin time [0-100]

This parameter sets the time delay before a shut-off below P27 occurs. It is only used by the Hydrovar® controller if P34 = STP. It affects the control of the pump for HCS, MSE and MSY control modes. Default: 0 s.

P36

Window [0-100]

This parameter sets the ramp control interval, as a percentage of the pressure setpoint. It is used to define the range of pressures, around the setpoint, in which the Hydrovar® controller uses slow acceleration and deceleration ramps instead of fast ones. It affects the control of the pump for HCS, MSE and MSY control modes (also see Par. 6.6.2). Default: 10%.

P37

Hysteresis [0-100]

This parameter sets the slow ramp hysteresis, as a percentage of P36. It helps define the pressure range, around the setpoint, in which Hydrovar® goes from slow acceleration ramp (P28) to slow deceleration ramp (P29). The parameter affects the control of the pump for HCS, MSE and MSY control modes (also see Par. 6.6.2). Default: 80%.

6.6.3 Example: Effective Required Value

Pumps activation in cascade modes:

1. Lead pump reaches its P60 (Enable Speed).

2. Actual value falls to the cut in-value of the 1st assist pump. The 1st assist pump switches on automatically. (Cut-in value = P01 (Required Value) - P59 (Actual Value Decrease))

3. A new required value, P02 (Effective Required Value) is calculated after the start up.

Page 40

en – Original instructions

Calculation of Effective Required Value in Cascade Serial (MSE):

K = number of active pumps Pr = pump priority

P02 (Actual Required Value) = P01 (Required Value) + (K – 1) * P58 (Actual Value Increase) – (Pr – 1) * P59 (Actual Value Decrease)

Calculation of Effective Required Value in Cascade Synchronous (MSY):

K = number of active pumps (K ≥ Pr) P02 (Actual Required Value) = P01 (Required Value) + (K – 1) * (P58 – P59)

Behaviour of P58 (Actual Value Increase) and P59 (Actual Value Decrease):

 if P58 (Actual Value Increase) = P59 (Actual Value Decrease) → Pressure constant,

independent of how many pumps are in operation.

 if P58 (Actual Value Increase) > P59 (Actual Value Decrease) → Pressure rises when assist

pump switches on.

 if P58 (Actual Value Increase) < P59 (Actual Value Decrease) → Pressure decreases when

assist pump switches on.
