ONEMATIC
0. DESCRIPTION.
ONEMATIC is a compact automatic control unit for controlling pumps with single-phase and three-phase motors. The system
manages the start and stop of the pump depending on the pressure detected by its internal transducer and the flow detected by the
internal flow sensor. It can be run either in pressure-dependent mode (start pressure and stop pressure) or on/off mode (start
pressure between 1÷5 bar, stopped by the flow sensor).
1. CLASSIFICATION AND TYPE.
According to EN-60730-1 ONEMATIC is a unit of independent assembly, type 1B with software of class A, for floodproof installation in
clean or slightly contaminated environments.
2. MAIN CHARACTERISTICS.
Pump controlled by power relay.
2 operating modes: pressure-dependent or on/off mode.
Control and protection system against over-current.
Control and protection system against dry running.
ART function (Automatic Reset Test). When the unit is stopped due to a lack of water, the ART system attempts to re-start the unit in
programmed intervals.
Automatic restore of system after interruption of power supply. System restores the previous mode.
Volt-free contact for monitoring the alerts displayed in screen, which were caused by irregularities or problems within the system.
Input for monitoring the minimum water level in inlet tank. This function is independent of the protective system against dry running and
optional.
Internal pressure transducer.
Internal flow sensor.
Control panel:
LCD screen, for configuration menu and indication of alerts with permanent pressure indication.
START/STOP push-button to operate the pump manually.
AUTOMATIC push-button with mode LED .
Keyboard for accessing the configuration menu.
Digital gauge.

1.- LCD screen: during the configuration process, it shows the different parameters. When ONEMATIC is running, it shows the current
pressure, the configured target pressure and the alerts.
2.- Push-button PUMP Start-Stop: will only run with the automatic mode disabled (AUTO LED off).
3.- Push-button AUTO On/Off: for choosing between manual and automatic operating modes.
4.- Push-button MENU: for accesing or exiting the configuration menu.
5.- Push-button ENTER: used for saving configured values. Each time the button is pushed, a new field opens in the configuration
menu. Press MENU if you wish to exit the configuration sequence.

7.- LINE LED (green): lit when the unit is connected to the electric supply.
8.- FAILURE LED (red): lit or flashing depending on type of failure.
9.- AUTO LED (green): lit in automatic mode and off in manual operating mode.
10.- PUMP LED (yellow): lit when the pump is running.
