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 dierential 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: dierential, 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 qualied 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 dieren-
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 congure
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 congu-
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 dierence beetween the starting pressure of main and au-
xiliary pumps, it is also the dierence 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 dierence 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 congured E01 will display pressu-
re and the unit congured 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.
WARNINGS AND ALARMS

A01
O
DRY-RUNNING
(Only for
SWITCHMATIC 2)
When is detected a dry-run operation the
pump is automatically stopped. By mean
of ENTER the normal operation can be
manually restored.
( ( O ) )
After the activation of the dry-running
alarm if the Automatic system reset (ART)
is enabled, a rst attempt at 5 minutes and
then an attempt every 30 minutes for 24
hours is performed in order to restore the
normal operation. This alarm can also be
reset manually with the ENTER push-but-
ton. If the alarm persists after 24 h we nd
a denitive alarm.
A11 O
DRY-RUNNING
(BY MINIMUM
PRESSURE)
Is displayed during normal operation if the
pressure is below the minimum pressure
(Px.x) - previously set - during a period
(txx) - also previously set - in the ADVAN-
CED MENU.
If at any time the pressure exceeds the mi-
nimum pressure, the operation is restored
automatically and the alarm is cleared.
Normal operation can also be restored
manually by pressing ENTER.
A02
O
OVERLOAD
(Only SW2)
Overcurrent alarm is activated when the
nominal pump current is exceeded.
4 automatic reset attempts prior to the
nal alarm are performed.
During the attempts display will show
current.
Normal operation can also be restored
manually by pressing ENTER.
( ( O ) )
A04 (((O))) FAST CYCLING
(Hammering)
This alarm can be unabled or activated in
the BASIC MENU. The alarm is activated
when 3 consecutive cycles occur in a range
lower than the set time (between cycle and
cycle).
If it has been activated rc1, this alarm does
not stop the normal operation but are
added 5 seconds to the start delay in order
to protect the electric pump.
If it has been activated rc2, the pump is
stopped.
To RESET the normal operation press
ENTER.
