The
Model B471 Multi-Stage Alternator is designed to control the operating sequence
of multi-stage pumping systems. it can also be used to maintain the desired
level of pressure on air compressor systems. Four PUMP SELECT DIP switches
located on the front panel allow the alternator to control a single-pump,
two-pump, three-pump or four-pump system. Only one switch needs to be set for
the total number of pumps in the system.
The Model B471 will assure that
only the necessary pumps are operating, and that the run time for each pump is
approximately equal. Pumps are sequenced “first-on” and “first-off.” If the
pumping demand requires only one pump at a time, the alternator will start the
next pump in sequence each time an input switch is closed. Input switches may be
float switches, pressure switches, flow switches, etc., as required by the
application.
Potential uses for the Model B471 include water supply
systems, sewage disposal plant systems, storage tank filling systems, air
compressor systems, irrigation and water recycling systems. |
