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.
• Available settings:
• Stand-by mode.
• Minimum period between fast cycles.
• Start and stop delay.
• Volt-free contact for monitoring the alarms displayed in the screen (only
version A).

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.
