General Description
Intelligent Three Phase Duplex Sewage Pump Controller AC380V Input Voltage , DOL Start Type , One Button Calibration.
L932-s Sewage Pump controller ,is a smart and intelligent three phase fully automatic pump controller with built-in water level control .
It is very useful in water and waste water applications,The unit features an advanced microprocessor controller bonded to the PCB boards within the enclosure. The unit will support two Three phase 380 VAC pumps rated up to 15KW.
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.)
Other Features
●Should tank levels become too high or too low, different audible and visual alarms will be triggered for the duration of the fault. A single or double flash will indicate the fault type.
●The audible alarm may be muted as per setting time by briefly pressing an ‘STOP ‘Mute button on the front side of the cabinet.
●The two motors will operate alternately with each cycle to distribute wear evenly. Should one pump motor fail, the unit will automatically restart using the alternate pump motor.
●When one pump or pipe get broken ,can disable one pump then alternation into other pump as running pump always.
●Pump start delay time and pump stop delay time can be adjustment by user.
