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 2T is an electronic pressure switch with integrated digital
manometer. It manages the start and stop of a three-phase pump up to
4kW (5,5 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 dierential pressure switch and as reverse pressure
switch.
Unit SWITCHMATIC 2T in addition to all the features of the basic SWIT-
CHMATIC includes instantaneous reading of current drawn. This paten-
ted system controls and manages the overcurrent, dry-run operation and
fast-cycling.
Unit SWITCHMATIC 2T in addition to all the features of individual assem-
bly includes the option to be synchronized to another unit SWITCHMATIC
2T managing and protecting 2 pumps operating in cascade with alterna-
ted starting sequence.

HYDRAULIC INSTALLATION (diagram A)
SWITCHMATIC 2T equipment must be threaded to a tting G1/4”
male at the pump´s outlet.
Before connecting the SWITCHMATIC 2T 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 230-400V.
If you have purchased the unit without cables follow diagram B:
• Use cables type H07RN-F 4G1 or 4G1,5 with section enough to the power
installed.
• Do the pump connection U, V, W and
• Do the power supply connection L1, L2, L3 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!
CONTROL PANEL (diagram C)
The meanings of the dierent control panel elements are summarized on the
following tables, where:
• O means lit LED light.
• ( ( O ) ) means slow-ashing.
• (((O))) means fast-ashing.

SYNCHRONISATION
SWITCHMATIC 2T can be synchronized to another unit SWITCHMATIC 2T
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 dierence beetween the starting pressure of main and au-
xiliary pumps, it is also the dierence 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 dierence 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 congured E01 will display pressu-
re and the unit congured 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. Press ENTER to disconnect the device. It ill be displayed OFF.
2. Open the taps living the hydraulic net without pressure.
3. Press simultaneously the buttons and until the display show 0.0
ashing.
4. Press to validate.

O
DRY-RUNNING
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 denitive 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
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.

A04 (((O))) FAST CYCLING
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.
