Pump controller TOSCANO

Pump controller for wastewater and stormwater.

• Unit for waste & sewage stations, control and protection of 2 pumps (up to 7.5 CV 400 V) with automatic alternation. Control through 2, 3 or 4 floats or level switches.
• Three-phase or single-phase.
• Dual voltage supply 230/400 VAC.
• Phase failure protection.
• Protection against failure in wiring to pump.
• Over-voltage protection.
• Overload protection.
• Protection against dry running through floats.
• Guaranteed against connection failures.
• Protection against jammed impeller during long resting periods. Unit activates motor for one second every 24 hours (only in AUTO mode).
• Assured operation on failure in any float.
• Assured operation of first pump on failure of the second one.
• Second pump delay (re-starting due to supply cut).
• Electronic overload relay, scalable (for each pump).
• Audible high level alarm (90dB).
• Operation selection (simultaneus or delayed shutdown).
• Control elements are low voltage.
• Load break safety switch.
• Calibrated fuse switch.
• Power contactors.
• Pilot lights for VOLTAGE and HIGH LEVEL.
• Pilot for ON/OFF and OVERLOAD for each pump.
• Overload alarm reset button.
• Wide diameter range and high protection in cable glands.
• Option: magnetic circuit breaker.
• Adjustable temporisation of motor shutdown.
• Six alarm outputs: General alarm, High level, Motor 1 running, Pump 2 running, Pump 1 overload, Pump 2 overload.
• General alarm output at 230 VAC (on request).
• Auxiliary inputs for thermal probes (klixon).
• MAN-O-AUTO buttons per pump.
• Includes batteries for high level alarm in case of supply cut.
• Correct sense turn indication light (three-phase motors).
