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 singlephase pump up to
2.2kW 3 HP. Cutin and cutout 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, dryrun operation and
fastcycling.
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.
CLASSIFICATION AND TYPE
According to IEC 607301 and EN 607301 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 cutin and cutout pressures.
• Integrated digital pressure gauge with bar and psi indication.
• Inner pressure transmitter.
• Dryrun protection:
• Through minimum adjusted height for basic SWITCHMATIC.
• Through the instantaneous current consumption in case of SWIT
CHMATIC 2.
• Overcurrent protection only SWM2.
• ART Function Automatic Reset Test. When the device has stopped
the pump by the intervention of the dryrunning protection system,
the ART tries, with scheduled basis, to restart 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 startstop cycles are produced this alarm is
activated and is delayed the start of the pump. Must be activated in
the step 2 of the BASIC MENU rc1.
• Manual start pushbutton ENTER.
• 3 operation modes: diff erential, reverse and synchronized only
SWM2.
• Control panel with 3digit display, LED indicator lights and push
buttons.
• Voltfree contact for monitoring the alarms displayed in screen origi
nated by irregularities or problems of the system only type SWITCH
MATIC 2A.
• Available settings:
• Standby mode.
• Minimum period between fast cycles.
• Start and stop delay.

HYDRAULIC INSTALLATION diagram A
SWITCHMATIC equipment must be threaded to a fi 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 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 115230V.
If you have purchased the unit without cables follow diagram B:
• Use cables type H07RNF 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!
CONTROL PANEL diagram C
