Cycle Press to initiate one complete dispense cycle. Press and hold while in the time override mode for continuous cycle. Time override Press to override time control. [. . . ] This connection will be made during valve installation. 6 / Setup Power 1. Press the time override button to place the controller in manual mode (---). Adjusting the Spray 1. Turn the nozzle air pressure on the controller to zero. Using the needle stroke control knob on the 781S valve, set the fluid flow rate to one or two drops per second. Check flow rate by actuating the controller in the time override mode. Make valve stroke adjustments when the controller is off. Set the nozzle air pressure on the controller to 10 psi (0. 7 bar) and actuate the controller. To change fluid flow, use the needle stroke control knob , and/or tank air pressure. Note: Avoid tight stroke settings with high tank pressure. 4. To change nozzle air, use the nozzle air pressure regulator . Higher pressures will provide finer spray. Return to the time control by pressing the time override button . The display should show the time setting. Adjust the deposit time to 0. 5 seconds by using the time set and decimal buttons. VALVEMATE 7040 Note: Optimal results will be obtained 3. The conwith the proper combination of time troller will open the valve for 0. 5 secsetting, needle stroke control knob, onds. Adjust time and test deposits and reservoir and nozzle air pressure. until desired output is obtained. 7 / Adjusting the Spray Programming Nozzle Air Delay Nozzle air delay is the time the nozzle air continues to spray after the fluid is turned off. When spot marking with low viscosity fluids, the delay can be reduced to prevent blowing out the center of the mark. The delay can be increased with high viscosity fluids and greases to provide a spreading out effect. Press and hold the time override button while turning power switch on. The display will read "SEL" (select). Press either the up or down time set buttons once and release. The current nozzle air-delay setting will be displayed. [. . . ] Note: There will be a maximum voltage drop of 2. 0 VDC through the feedback circuit with each 7040 that is added to the series. The input power should be adjusted for this drop to ensure that the required voltage is available to operate the load. Maximum input voltage to terminals 3 and 4 must not exceed 30. 0 VDC. 5-24 VDC Source + 1. Parallel circuit diagram for Voltage Initiate. 54321 9876 54321 9876 54321 9876 _ 2. [. . . ]
