Three Phase Sewage Water Pump Controller Specialized In Sewage Lifting ,Available From 0.75-15kw ,One Button Calibration, IP 54,Both Auto &Manual Mode


1.GENERAL DESCRIPTION


L932-S pump controller is a compact wall mounted unit which will manage the operation of a Duty & Standby pump motor combination applicable for waste water management.


Pump Controller adopt the digital control chip, set upper and down liquid level and automatic control in one function. Automatic and manual two working mode can be selected..the controller have loss phase, overload, empty load, over voltage and under voltage function protection. Small size .elegant appearance. Applicable to a variety of water supply control occasions.

Under normal operation the two pumps under control will alternate use with every pump cycle to ensure even equipment wear & loading. If one pump should fail to reduce water levels when operated, then the alternate pump will take over and an alarm condition will be flagged.

One inside built level transmitter will inform the controller when the container has been pumped dry, when a container is in danger of overflowing, or when a normal pump cycle needs to be initiated. Real time water level can be displaying on the LCD,pump can be cut in and cut off as per in-advanced setting of water level. A number of alarm conditions will be displayed and electronically recorded where normal operating limits have been exceeded.

The controller unit is housed in a tough IP54 rated plastic enclosure with a LCD displaying front so that various status indicators may be viewed. This allows routine pump checks and maintenance to be carried out without the presence of an electrician. (Installation and maintenance of all electrical components will still require the presence of a qualified electrical contractor.)
