Under voltage (outputvoltage too low)Supply voltage too low Increase the supply voltage.Sieve screen center hub bondingdamagedReplace the sieve screen.Damaged generator Contact the Vibrasonic systemmanufacturer.2. Over voltage (outputof generator too high)Poor contact surfaces betweentransducer and sieve screenRemove the transducer from thescreen and clean the mating surfaceswith acetone. Assemble thetransducer to the screen using theVibrasonic Transducer and SieveScreen Installation procedure.Loose transducer Tighten the transducer using thesupplied torque wrench. Refer to theVibrasonic Transducer and SieveScreen Installation procedure.Damaged sieve screen matingsurfaceReplace the sieve screen.Damaged transducer matingsurfaceReplace the transducer.3. Open circuit (opencircuit in output fromcontroller)Disconnected transducer cable Check the transducer cableconnections.Damaged control cable orconnectorReplace the control cable.Loose or damaged wiring in thecontrollerCheck the controller wiring. Tightenany loose connections.Damaged transducer Replace the transducer.4. Short circuit (shortcircuit in output fromcontroller)Short circuit in control cable Replace the control cable.Short circuit in either control ortransducer cable connectorsThoroughly clean the connectors.Short circuit in transducer Replace the transducer.
