Time Mark Model 442-120 Flow Controller

The Model 442 multi-stage alternator is designed to control the operating sequence of multi-stage motor/pumping systems. It can also be used to maintain ideal pressure levels in air compressor systems. Four motor selection DIP switches located on the front panel allow the alternator to control a single motor/pump,two motor/pump,three motor/pump or four motor/pump system. The Model 442 will ensure that only the necessary motors/pumps are run and that each motor/pump is run for approximately equal amounts of time. The motors are turned on sequentially and turned off at the same time. If the motor/pumping demand requires only one motor/pump at a time,the alternator will start the next motor/pump in sequence each time the input switch is closed. Depending on the application requirements,the input switch can be a float switch,pressure switch,flow switch,etc. Potential uses for the Type 442 include water supply systems,wastewater treatment plant systems,tank filling systems,air compressor systems,irrigation and water recycling systems.
