Operating Characteristics; Technical Characteristics - Coelbo SWITCHMATIC 2T Manual De Instrucciones

1. 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.
2. 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 differential 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.

3. OPERATING CHARACTERISTICS

• Adjustable cut-in and cut-out pressures.
• Integrated digital pressure gauge with bar and psi indication.
• Inner pressure transmitter.
• Dry-run protection: through the instantaneous current consumption
in case of.
• Overload protection.
• Overvoltage protection.
• Undervoltage 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 5 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: differential, 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.

5. HYDRAULIC INSTALLATION (diagram A)
SWITCHMATIC 2T equipment must be threaded to a fitting 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.
6. ELECTRIC CONNECTION (diagram B)
The electric connection must be performed by qualified 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 differen-
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
If you have purchased the unit without cables follow
• 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 first
one to be mounted during the assembly and the last one to be discon-
nected during the dismantling. The earth conductors connections are
compulsory!
