520-211-000 2/01 Model S05 Non-Metallic Design Level 1 Page 17SOLENOID SHIFTED AIRDISTRIBUTION VALVE OPTIONWarren Rupp’s solenoid shifted, airdistribution valve option utilizes electricalsignals to precisely control yourSandPIPER’s speed. The solenoid coilis connected to the Warren RuppSolenoid Rate Controller/Batch Control,or a customer - supplied control.Compressed air provides the pumpingpower, while electrical signals controlpump speed (pumping rate).OPERATIONThe Solenoid Shifted SandPIPER has asolenoid operated, air distribution valvein place of the standard SandPIPER’spilot operated, air distribution valve.Where a pilot valve is normally utilizedto cycle the pump’s air distribution valve,an electric solenoid is utilized. As thesolenoid is powered, one of the pump’sair chambers is pressurized while theother chamber is exhausted. Whenelectric power is turned off, the solenoidshifts and the pressurized chamber isexhausted while the other chamber ispressurized. By alternately applying andremoving power to the solenoid, thepump cycles much like a standardSandPIPER pump, with one exception.This option provides a way to preciselycontrol and monitor pump speed.BEFORE INSTALLATIONBefore wiring the solenoid, make certainit is compatible with your system voltage.Solenoid Connector#2 TerminalNeutral(Negative)#1 TerminalPower(Positive)3rd Terminalfor ground.WiringDiagramBefore wiring, removeterminal block fromconduit connector.To Control
