SWITCHMATIC - SWITCHMATIC 2
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 is an electronic pressure switch with integrated digital ma
nometer. It manages the start and stop of a singlephase pump up to
2.2kW 3 HP. 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 diff 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.

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. Must be activated in

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 qualifi 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.
Check if power supply is between 115230V.
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 .
• Do the power supply connection L1, N and .
• The earth conductor must be longer than the others. It will be the fi rst
one to be mounted during the assembly and the last one to be dis
connected during the dismantling. The earth conductors connec
tions are compulsory!

Remark 2:
Basic SWITCHMATIC can only detect dryrunning operation
through the minimum pressure. This means that plumber must
determine the water column of the installation, the start pressu
re 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 fl ow requirement is excessive. In this case SWITCHMATIC would
activate a false dryrunning alarm.
If these concepts are not clear, it is preferable not confi gure this
protection or install the SWITCHMATIC 2 with accurate and easy
setting of dryrun detection.

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. SET identical cutin and cutout pressures in both units.
2. 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 diff erential d.XX.
3. Press repeatedly until exit the ADVANCED MENU.
4. Press in order to disable the units. Is displayed “OFF”.
5. Press again in both units in order to activate the synchronization.
Remark 3: after 10 cycles the unit confi gured E01 will display pressu
re and the unit confi gured E02 will display current in Amps.
ACCURATE DRYRUNNING DETECTION diagram C
In the SWITCHMATIC 2 model it is enough to set the rated current of the
pump in order to activate the overcurrent and dryrunning protection.
However, the accuracy of dryrunning detection can be improved by the
activation of DR1 parameter in the ADVANCED MENU. The following steps
must be followed:
1. Drain the hydraulic installation and verify that the hydropneumatic tank
is infl ated to the required pressure.
2. Go to the ADVANCED MENU:
 Press simultaneously + + during 5 seconds.
 Press 7 consecutive times to accept and go to the next step until
reaching dr0.
 Using , set dr1.
3. Press and close all the valves.
4. The pump will start, will fi ll the installation and will stop at the cutout
pressure.
5. Now, SWITCHMATIC 2 knows the current consumption curve of the
pump.
If you install a new pump this process should be repeated.
If you enter the CURRENT INTENSITY MENU by pressing for 3 seconds
all this process is invalidated because is predominant the rated current
manually introduced.
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 fl 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 fl ashes
with a fi gure.
3. Adjust the pressure with the arrows pushbuttons to get the pressure
desired.
4. Press to validate.
Remark 4: pressure sensor decalibration should not be a normal
event. If it is frequently repeated contact the technical service.
