Sweep System, Side Broom396Service Manual – CS7000Circuit DescriptionThe Following Conditions Must be Met for the Side Broom Sweep 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 400-amp Fuse F1 must be closed to provide positive voltage from the Battery to the load side of AuxiliaryContactor K9 and circuit breaker CB7.• The Ignition Switch S14 must be closed to provide positive voltage to the Auxiliary Contactor K9 coil. TheJ2-14 Output on the A1 Main Machine Controller provides ground to the Auxiliary Contactor K9 coil when theIgnition Switch S14 provides an input to the Key Switch Input J7-13.• The Auxiliary Contactor K9 must be closed to provide positive voltage to circuit breaker VACC1/CB1.• Circuit breaker VACC1/CB1 must be closed to provide positive voltage to the Side Broom Motor Contactor K8coil.• The J2-15 Output on the A1 Main Machine Controller must provide a ground to the Side Broom MotorContactor K8 coil. J2-15 provides ground to K8 under the following conditions:– The A1 Main Machine Controller must receive a signal from the A3 Control Panel via the CAN BUS that theoperator has pressed the sweep and side broom switches.– The A1 Main Machine Controller must receive a signal from the A2 Drive Controller via the CAN BUS thatthe machine is moving forward or reverse.• Circuit breaker CB7 must be closed to provide positive voltage to the load side of Side Broom MotorContactor K8.• Side Broom Motor Contactor K8 must be closed to provide positive voltage to the Side Broom Motors M8 andM9.• The Side Broom Motors M8 and M9 must have connections to battery ground B-.Side Broom Actuator MotorThe J3-5 and J3-17 Outputs from the A1 Main Machine Controller provide voltage to the Side Broom ActuatorMotor M13. The output polarity determines whether the Side Broom Actuator Motor lowers or raises the sidebrooms.
