Spray System Operation The Multi Pro 5700–D spray system uses a positive displacement diaphragm pump to move spray solution from the spray tank to the boom nozzles. The spray pump is self–priming and has a dry crankcase. The downward stroke of the pumps’ two connecting rods and diaphragms create suction to allow fluid to be drawn from the spray tank to the pump via the suction tube, suction strainer, hoses, and connectors. A suction dampener placed in the suction line dampens suction pulses to smooth suction flow. Suction valves positioned in the pump valve chamber prevent fluid from being pumped back into the suction line. Leaks in the suction line will cause system problems and often will be indicated by erratic suction line jumping and excessive pump noise. Once to the pump, the fluid is pushed by the upward stroke of the pumps’ two connecting rods and diaphragms to the pressure side of the spray system through hoses, connectors, control valves, and spray nozzles. A pressure dampener at the pump outlet smooths system pressure pulsation. Pressure valves positioned in the pump head prevent fluid from being drawn back into the pump. Maximum pressure in the system is limited by a pressure relief valve located in the tank. A pressure gauge on the dash panel indicates spray system pressure. Battery current for spray system fuses, switches, valve motors, and other components is provided by the accessory solenoid when the machine ignition switch is in the RUN position. For spray system electrical component information and test procedures, see Chapter 5 – Electrical System. The machine operator controls the spray system on the Multi Pro 5700–D with electrical switches located on the spray console. Switches include a spray pump on/off switch, an application rate (increase/decrease) switch, an agitation control switch and three boom control switches. These switches control the PWM Valve, the agitation control valve and three boom control valves. Additionally, a master (foot) boom valve switch allows the operator to turn off/on all three boom sections. The spray pump is directly coupled to and driven by a hydraulic motor. Flow from the hydraulic gear pump to the motor is controlled by the Pulse Width Modulated (PWM) Valve. Based on available current (mA) from the spray pump application rate (increase/decrease) switch, the PWM spool valve directs gear pump flow to the spray pump hydraulic motor. This hydraulic flow causes the motor to rotate the spray system pump for spray system operation. When the spray pump is on, application rate (increase/ decrease) switches allow the operator to adjust electrical current to the PWM Valve solenoid. Higher current (rate increase) to the PWM solenoid increases hydraulic flow to the spray pump motor and results in a higher spray pump speed with more output/pressure. Lower current (rate decrease) to the PWM solenoid decreases hydraulic flow to the spray pump motor and results in a lower spray pump speed with less output/pressure. Desired spray pump pressure should be based on boom nozzle selection and ground speed (see Nozzle Selection Guide (Toro Form No. 3351–389) for information regarding boom nozzle selection). When the agitation switch is ON, the switch light is illuminated and the agitation control valve is opened. This open valve directs system flow to three agitation nozzles in the spray tank. When the agitation switch is OFF, the agitation control valve is closed so no flow is available for tank agitation nozzles. When a boom control switch (left, center or right) is ON, the switch light is illuminated and the boom control valve for that boom is opened. This open valve directs system flow to the spray nozzles located on the boom section. When a boom control switch is OFF, the boom control valve is closed so no flow is available to that spray boom. A manually adjustable boom bypass valve is incorporated in each of the boom control valves. Proper adjustment of the boom bypass valves prevents system pressure changes when a boom section is shut off. Flow from the boom bypass valves is directed back to the tank (boom bypass). An optional Pro Control Spray System is available for the Multi Pro 5700–D. This system includes a console computer and an inline flowmeter to control the spray pressure system. The flowmeter is positioned in the pressure side of the spray system directly before the boom control valves. The flowmeter measures spray boom flow. The Pro Control computer determines system application rate based on operator programming and inputs from the flowmeter and the ground speed sensor located in the right rear wheel motor. Additional Pro Control information can be found in the Pro Control Spray System Operator’s Manual. NOTE: When a vehicle is equipped with the optional Pro Control Spray System, the balancing valves on all boom valve motors must be fully closed. Spray System Multi Pro 5700–D Page 6 – 5 Spray System
