Typical Applications
Submersible Waste Water Pump Control
Using level switches, PM1000 can be used to automate up to
6 submersible wastewater pumps. Input signals from up to 4
level switches at 4 different levels provide enhanced control.
Line Pressure Control Applications
Using analog pressure
sensors, PM1000 can be used in industrial facilities or commercial
buildings in order to maintain a constant line pressure by
multiplexing required number of pumps. The line pressure can
be accurately maintained with the help of the microprocessor
control and analog pressure measurement in systems that have
air tank pressure balancing. Desired line pressure can be
set using the keypad interface.
 Irrigation
Applications
PM1000 is used in irrigation applications where demand fluctuations
are met by controlling multiple pumps. Using the microprocessor,
the pumps can be programmed to work in rotation and with sequential
control. Operation time is divided between the pumps with
lead pump switching to optimize wear and to extend the operating
life. The number of motors can be set to a desired value less
then the actual quantity, leaving a desired pump out of the
rotation sequence.
