Squeegee System345Service Manual – CS7000Circuit DescriptionThe following conditions must be met for the squeegee system to operate:• The Hopper Interlock Switch S3 must be closed.• There must be positive voltage to the J7-1 Interlock Input. For this to happen:– The Seat Switch S9 must be closed.– The Safety Relay K14 on the Steer By Wire Controller A5 must energize the coil to close the Safety RelayK14 contactor.– The Emergency Stop Switch S15 must be closed.– The Battery Interlock S13 must be closed.• The A1 Main Machine Controller must receive a signal from the A3 Control Panel via the CAN BUS that theoperator has pressed the scrub switch.• The J2-8 and J2-9 Outputs from the A1 Main Machine Controller provide voltage to the Squeegee ActuatorMotor M12. The output polarity determines whether the Squeegee Actuator Motor lowers or raises thesqueegee.Component LocationsThe Rear Squeegee Assembly is attachedto the Squeegee Support Assembly withtwo split Squeegee Clips that clamp ontohorizontal pins in the Squeegee SupportAssembly.The front of the Squeegee Support Assemblyis attached to the machine frame by apivoting Rod End. This allows the rearof the Squeegee Support Assembly andattached squeegee to tilt up and down, andpivot side-to-side to conform to the floorsurface. The two Squeegee Casters supportthe Squeegee Support Assembly on the floor.The rear of the Squeegee Support Assemblyrests on and is supported by the SqueegeeLift Arm. The pivoting Front Brackets onthe Squeegee Lift Arm are attached to themachine frame. The Squeegee Lift Actuatorraises and lowers the rear of the SqueegeeLift Arm, which pivots up and down to raiseand lower the Squeegee Support Assemblyand the attached Rear Squeegee Assembly.The Squeegee Support Assembly and RearSqueegee Assembly swing left-to-right toallow the Rear Squeegee Assembly to pickup water on the inside of the corner whenmachine is turning. The Extension Springsre-center the Squeegee Support Assemblyand Rear Squeegee Assembly once themachine is again moving in a straight line.RearSqueegeeAssemblySqueegee LiftActuatorSqueegeeLift ArmSqueegeeClip (2)SqueegeeSupportAssemblyRodEndFrontBracket (2)SqueegeeCaster (2)ExtensionSpring (2)
