SWITCHMATIC

This unit SWITCHMATIC is an electronic pressure switch with an integrated digital pressure gauge. It can manage the start and stop of single-phase electric pumps up to 3 HP (2,2 kW). Cut-in and cut-out pressure implementation can be set easily and accurately through user friendly control panel. Wiring is carried out identically to a conventional electromechanical switch.It can operate as a differential pressure switch or as an inverted pressure switch. SWITCHMATIC 2 includes also instantaneous current lecture and it can be mounted individually or in groups of 2

OPERATING CHARACTERISTICS -

ART function (Automatic Reset Test). If the device has been stoped due the action of the safety system against dry operation, the ART tries to connect the pump, with a programmed periodicity because the water supply could have been restored. - Sleep mode with low power consumption. - Inner pressure transmitter. - Integrated pressure gauge with bar and psi instantaneous display. - User friendly control panel with 3-digits display, led-lights and pushbuttons. - Dry-running protection by current (for type Switchmatic 2) and for minimal pressure (for type Switchmatic 1). - Rapid-cycle alarm: when the hydropneumatic tank has lost the air and frequent start-stops are produced an alarm is activated and is delayed the start. - Overload alarm (only type SWITCHMATIC 2). - Volt-free contact for monitoring the alarms displayed in screen originated by irregularities or problems of the system (only type SWITCHMATIC 2A). - Manual start. - Operation modes: differential, inversed differential and synchronized (only for Switchmatic2). - EMC certified and Electrical Safety certifed. - RoHs and WEEE compliant.
