CategoryContentW713BPhoto for Reference Pressure OptimizationPressure StabilityThe pressure change curve is more stable, and the frequency change is smaller after stabilizationAlternate TransitionYes, the transition tends to be smooth and excessive (the transitional pump looks at the difference between the given pressure L and the feedback pressure P to adjust the frequency, and it will stop when L-P<0.2bar. If the water consumption suddenly increases at this time, the L-P>0.2 bar, alternating water pumps will speed up the frequency regulation pressure, when L-P=0.2bar, slowly adjust the frequency for a smooth transition)ModeControl ModeConstant pressure, Constant differential pressur,Constant temperature, Constant differential temperatureLinkageModeSynchronize, Master-slave, Big-small pump, One duty one standby, One VFD drive two pumpsManual/auto Mode SwitchingCan be switched by button or terminal.Button switch: press the and buttons at the same time for manual/auto switch (also switchable in case of failure)Terminal switching:S2-COM off: auto control S2-COM on:manual control In manual control, the manual frequency can be adjusted through the up and down buttons, and the influence of pressure is shielded, which is more comprehensiveAlternating ModeAlternate by time (Alternate when time comes to sleep)Alternate sleep and wake up, and alternate by timeUpper and Lower Pool ControlAvailable (S1~S4 terminal control)Independent Start and Stop ControlAvailable, start and stop is controlled by the inverter (can be controlled by panel or S4 terminal)Outward ExpansionGeneral Frequency Converter (such as PLC)Compatible with this modeConnect the Touch Screen of BEDFORD AvailableThird-party DevicesDirect connection(Mob Bus RTU communication protocol)External Interface FeaturesAnalog Input Digital Input4-way1.
