Solution System323Service Manual – CS7000– The Extended Scrub Level (float) Switch S4 in the recovery tank must be open to prevent the J7-15 Inputfrom going to battery negative. Note the switch opens when there is adequate water in the recoverytank, and closes when the recovery tank is empty.The Following Conditions Must be Met for the Low Pressure Wash Hose to OperateNote: The low pressure wash hose does not require the interlocks to be closed to operate.• The low pressure wash function must be installed in the configuration menu.• The 400-amp Fuse F1 must be closed to provide positive voltage from the Battery to the load side of AuxiliaryContactor K9.• 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 voltage to the Key Switch Input J7-13.• Circuit breaker VACC2/CB2 must closed to provide positive voltage to the Low Pressure Pump M23.• The J3-24 Output must provide negative ground to the Low Pressure Pump M23. This output will be activewhenever the key switch is on.• The internal pressure switch in the Low Pressure Pump M23 must be closed for the pump to run.Note: The internal pressure switch in the low pressure pump is set to switch the pump on at 25 psi± 5 psi (when the hose nozzle is opened), and shut pump off at 45 psi (when the hose nozzle isclosed).The Following Conditions Must be Met for the EcoFlex™ System to OperateThe J2-19, J2-7, J2-32 and J2-21 PWM Outputs provide power to the Chemical Metering Pumps M17 and M18respectively under the following conditions:• The detergent system and EcoFlex™ system must both be installed in the configuration menu.• The A1 Main Machine Controller must receive a signal from the A3 Control Panel via the CAN BUS that theoperator has pressed the scrub and EcoFlex™ switches.• The A1 Main Machine Controller must receive a signal from the A2 Drive Controller via the CAN BUS that themachine is moving forward or reverse.The Following Conditions Must be Met for the High-pressure Spray System to Operate• The high pressure wash system must be installed in the configuration menu.• The J3-8 Output provides positive voltage to the High Pressure Pump Clutch under the following conditions:– The A1 Main Machine Controller must receive a signal from the A3 Control Panel via the CAN BUS that thescrub and detergent systems are enabled.– The A1 Main Machine Controller must receive a signal from the A2 Drive Controller via the CAN BUS thatthe machine is in Neutral and NOT moving forward or reverse. (The feature is disables when themachine is moving.)• The High Pressure Pump Clutch must be connected to battery negative.
