This SWITCHMATIC 2 unit is an electronic pressure switch with integrated digital pressure gauge. It can manage the starting and stopping of single-phase electric pumps up to 3 HP (2.2 kW). The implementation of the on and off pressure can be set easily and precisely via the intuitive control panel. The wiring is identical to that of a traditional electromechanical switch, it can operate as a differential pressure switch or as an inverted pressure switch.

SWITCHMATIC 2 also features instantaneous current reading and can be mounted individually or in groups of 2 synchronized pumps operating in cascade with alternating operating sequence. This patented version controls and manages overcurrent, dry-running protection of the pump and rapid cycling protection. The SWITCHMATIC 2A unit includes an alarm output.

– ART function (Automatic Reset Test). If the device has been stopped due to the intervention of the dry-running safety system, the ART attempts to activate the pump, with a programmed periodicity because the water supply may have restored.
– Sleep mode with low energy consumption.
– Internal pressure transmitter.
– Integrated pressure gauge with instant display in bar and psi.
– Intuitive control panel with 3-digit display, luminous LEDs and buttons.
– Protection against dry running by current.
– Fast cycle alarm: when the hydropneumatic tank has lost air and there are frequent starts-stops, an alarm is activated and the start is delayed.
– Overload alarm
– Clean contact for monitoring alarms displayed on the screen originating from system irregularities or problems.
– Manual start.
– Operating modes: differential, reverse differential and synchronized.
– EMC certificate and electrical safety certificate.
– Compliant with RoHS and WEEE

– 3-digit display:
– Mode of operation: Instantaneous pressure.
– Set mode: activation and deactivation of the pressure.
– Bar-psi led lights (green):
– Operating mode: light bar or psi.
– Pump on: flashing bar or psi.
– Star-Stop led light (green):
– Bright: Press Start or Press Stop displayed.
– Flashing: Psart or Pstop setting.
– Buttons: increase or decrease configuration parameters.
– ENTER button:
– Manual start and stop.
– Confirm the configuration value.
– Alarm LED (red): dry running and fast cycles.
– Led-light “A” (yellow):
– Bright: Displays the instantaneous current consumption of the pump.
– Flashing: Setting of the maximum current of the pump.
– Alarm led: dry running, overcurrent, fast cycles
– Button “A”: sets and displays the intensity of the current.
