1. GENERAL
Read carefully the instructions before installing this unit. Verify
the technical characteristics of the motor in order to assure the
compatibility with the device.
2. DESCRIPTION (diagram A)
SWITCHMATIC 1 is an electronic pressure switch with integrated
digital manometer. It manages the start and stop of a single-pha-
se 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 diferential pressure switch and as reverse pres-
sure
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.
3. 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).

SWITCHMATIC units 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.
6. ELECTRIC CONNECTION (diagram B)
The electric connection must be perormed by qualied per-
sonal 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 diferential switch o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) or C1, C2 and
to the control panel (Only SW3)
• Do the power supply connection L1, N and . (SW1-2-3) or
24V + and - (SW3 24V)
• 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 disconnected during the dismantling. The earth
conductors connections are compulsory!
• (Only version in-out) The device has a volt-free contact for
monitoring the alarms displayed in the screen originated by
irregularities or problems of the system. See Diagram C for
connection.
• (Only version in-out) There is a level switch input in the auxiliary
circuit. See Diagram C for connection.

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 alse dry-running
alarm.
Ithese concepts are not clear, it is preerable 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
11. SYNCHRONISATION (ONLY FOR SWITCHMATIC 2)
SWITCHMATIC 2 can be synchronized to another unit SWITCH-
MATIC 2 managing and protecting 2 pumps operating in cascade
with alternated starting sequence. Next steps must be followed:
1. GO TO ADVANCED MENU: + +
-Instep 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 pressu-
res d.XX. This is the diference beetween the starting pressure
omain and auxiliary pumps, it is also the diference 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 diference
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 synchroni-
zation.
Remark 4: ater 10 cycles the unit congured E01 will display
pressure and the unit congured E02 will display current in
Amps.
