Description
Electronic pressure switch. Patented model.
This unit SWITCHMATIC 1 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.
OPERATING CHARACTERISTICS
– Inner pressure transmitter.
– Integrated pressure gauge with bar and psi instantaneous display.
– User friendly control panel including manual start push-button, 3-digits display, led-lights
and pushbuttons.
– Dry-running protection by minimal pressure (for type SWITCHMATIC 1).
– ART function (Automatic Reset Test). If the device has been stopped 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.
– 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.
– Sleep mode with low power consumption.
– Advanced configuration menu: differentials, delay settings and other parameters.
