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.
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 minimal pressure.
– 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.
– Manual start.
– EMC certified and Electrical Safety certifed.
– RoHs and WEEE compliant.
CONTROL PANEL
– 3 digits display:
– Operating mode: Instantaneus pressure.
– Set mode: Cut in and cut out pressure.
– Bar-psi led-lights (green):
– Operating mode: Bright bar or psi.
– Pump on: Flashing bar or psi.
– Star-Stop led-light (green):
– Bright: displayed Pressure start or Pressure stop.
– Flashing: Setting Psart or Pstop.
– Push Buttons: Increase or dicrease configuration parameters.
– ENTER push-button:
– Manual start and stop.
– Confirm configuration value.
– Alarm led-light (red): dry-run and fast cyclying.
