Three Phase Duplex Sewage Pump Controller Available From 0.75-15kw
,With Manual &Auto Mode ,Ip54
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.
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.
L932-S 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
- Should tank levels become too high or too low, different audible

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
