GENERAL

Read carefully the instructions before installing this unit. Verify the tech-

nical characteristics of the motor in order to assure the compatibility with

the device.

DESCRIPTION (diagram A)

SWITCHMATIC 1 is an electronic pressure switch with integrated digital

manometer. It manages the start and stop of a single-phase pump up to

2.2kW (3 HP) (SW1-2). Cut-in and cut-out pressures are easily adjustable

through the users control panel.

Wiring is analogous to the traditional electromechanical switch.

It can operate as a dierential pressure switch and as reverse pressure

switch.

Unit SWITCHMATIC 2 in addition to all the features of the basic SWITCH-

MATIC includes instantaneous reading of current drawn. This patented

system controls and manages the overcurrent, dry-run operation and

fast-cycling.

Unit SWITCHMATIC 2 in addition to all the features of individual assembly

includes the option to be synchronized to another unit SWITCHMATIC 2

managing and protecting 2 pumps operating in cascade with alternated

starting sequence. The SWITCHMATIC 3 unit is ideal for a control panel as

it has a dry contact output.

CLASSIFICATION AND TYPE

According to IEC 60730-1 and EN 60730-1 this unit is a control sensor

device, electronic, independent assembly, programming type A with action

type 1B (microdisconnection). Operating value: I <20% I learned. Pollution

degree 2 (clean environment). Rated impulse voltage: cat II / 2500V. Tem-

peratures for ball test: enclousure (75) and PCB (125).

OPERATING CHARACTERISTICS (diagram C)

• Adjustable cut-in and cut-out pressures.

• Integrated digital pressure gauge with bar and psi indication.

• Inner pressure transmitter.

• Dry-run protection:

• Through minimum adjusted height for basic SWITCHMATIC 1/3.

• Through the instantaneous current consumption in case of SW2.

• Overcurrent protection.

• Overvoltage protection.

• ART Function (Automatic Reset Test). When the device has stopped

the pump by the intervention of the dry-running protection system,

the ART tries, with scheduled basis, to re-start the pump in order to

restore the water supply. See “ART. Automatic reset function“. Must be

activated in the step 6 of the ADVANCED MENU (Ar1).

• Fast cycling: when the hydropneumatic tank has lost too much air and,

consequently, frequent start-stop cycles are produced this alarm is

activated and is delayed the start of the pump. Activated (rc2).

• Manual start push-button (ENTER).

• 3 operation modes: dierential, reverse and synchronized.

• Control panel with 3-digit display, LED indicator lights and push-

buttons.

HYDRAULIC INSTALLATION (diagram A)

SWITCHMATIC equipment must be threaded to a tting G1/4” male

at the pump´s outlet.

Before connecting the SWITCHMATIC verify that the hydraulic system is

properly installed, especially if the hydropneumatic tank is pressurized.

ELECTRIC CONNECTION (diagram B)

The electric connection must be performed by qualied personal in

compliance with regulation of each country. Before doing manipulations

inside the device, it must be disconnected from the electric supply.

Wrong connection could spoil the electronic circuit.

The manufacturer declines all responsability in damages caused by

wrong connections.

When carrying out the electrical connection it is compulsory to use a dieren-

tial switch of high sensitivity: I = 30 mA (clase A o AC). It is compulsory to use a

magnetothermic switch adapted at the motor load.

Check if power supply is between 115-230V (SW1-2).

If you have purchased the unit without cables follow diagram B:

• Use cables type H07RN-F 3G1 or 3G1,5 with section enough to the power

installed.

• Do the pump connection U, V and (SW1-2) o 1, 2 y al cuadro (Only

SW3)

• Do the power supply connection L1, N and .

• The earth conductor must be longer than the others. It will be the rst

one to be mounted during the assembly and the last one to be discon-

nected during the dismantling. The earth conductors connections are

compulsory!

• (Only version A) The device has a volt-free contact for monitoring the alarms

displayed in the screen originated by irregularities or problems of the system.

For the connection see Diagram C.

Remark 2:

Basic SWITCHMATIC 1/3 can only detect dry-running

operation through the minimum pressure. This means that

plumber must determine the water column of the installa-

tion, the start pressure of the pump and place the minimum

pressure below the start pressure.

It can also occur that pumping system is running out of its

curve so that the pump is unable to provide the minimum

pressure because the ow requirement is excessive. In this

case SWITCHMATIC 1/3 would activate a false dry-running

alarm.

If these concepts are not clear, it is preferable not congure

this protection or install the SWITCHMATIC 2 with accurate

and easy setting of dry-run detection.

Remark 3:

By choosing “no” (normally open) it will operate as an auxi-

liary pressure control element in the suction of the pump. It

will restart when the suction pressure reaches the congu-

red PStart.

Example: - PStop: 0,9 bar

- PStart: 1,2 bar

SYNCHRONISATION (ONLY FOR SWITCHMATIC 2)

SWITCHMATIC 2 can be synchronized to another unit SWITCHMATIC 2

managing and protecting 2 pumps operating in cascade with alternated

starting sequence. Next steps must be followed:

1. GO TO ADVANCED MENU: + +

- In step 2: select E01 in a unit (this one will be the master) and select E02

in the other unit (this one will be the slave).

- In step 3: select identical parameters of gap between pressures d.XX.

This is the dierence beetween the starting pressure of main and au-

xiliary pumps, it is also the dierence beetween stop pressures of both

pumps.

2. Press repeatedly until exit the ADVANCED MENU.

3. SET identical cut-in and cut-out pressures in both units.

To optimize the synchronization, the minimum dierence between

the start and stop pressures must be at least 1 bar.

4. Press in order to disable the units. Is displayed “OFF”.

5. Press again in both units in order to activate the synchronization.

Remark 4: after 10 cycles the unit congured E01 will display pressu-

re and the unit congured E02 will display current in Amps.

PRESSURE SENSOR CALIBRATION

In case of wrong lecture of the pressure sensor it can be adjusted again.

For the pressure sensor calibration is necessary to have a pressure gauge

in the installation. Proceed following next steps:

ZERO REGULATION

1. Open the taps living the hydraulic net without pressure.

2. Press simultaneously the buttons and until the display show 0.0

ashing.

3. Press to validate.

FULL SCALE

1. Start the pump until cut-out of the pressure switch.

2. Press simultaneously the buttons and till the display ashes with

a gure.

3. Adjustthe pressurewith the arrowspush-buttons to getthe pressurede-

sired.

4. Press to validate.

Remark 5: pressure sensor decalibration should not be a normal

event. If it is frequently repeated contact the technical service.
