Driver for one single-phase or 3-phase pump at variable speed. Plug and play unit.
General electric supply is single-phase 230 Vac. Easy to setup and operate, as it’s only necessary to connect and select the setpoint pressure. It can be mounted individually (only one pump) or in group of 2 pumps communicated and operating in MASTER-SLAVE mode with alternated sequence of operation.
OPERATING CHARACTERISTICS
– Pump managed by frecuency converter (inverter).
– ART function (Automatic Reset Test). If the device has been stopped due to 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.
– MASTER-SLAVE operation mode. The group will consist of 2 communicated devices: a
main device configured like MASTER and an auxiliary device configured as SLAVE. The
operating system is alternated, the device configured as MASTER is the responsible of the
control but it does not imply that is the first to start when there is a flow demand.
– Automatic restore system after an interruption of power supply. This system restores the
previous mode keeping the configuration parameters.
– Inner pressure transducer with digital indicator,
– Inner current sensor with instantaneus digital reading.
– Control and information panel with 2 digits.
– Electronic input for detection of minium water level in aspiration tank – optional. This is independent
of the safety system against dry-running operation.
– Register of operational parameters. Information about: operating hours, counter of starts,
counter of connections to the power supply.
– Register of alarms. Information about type and number of alarms.
– Open PID in the expert menu.
