User manual EFD 7090

[. . . ] Time is displayed in real time from . 001 to 99. 9 seconds. In settings less than 1. 0 seconds, the decimal will not show. Pressure is identified with a flashing "P" for pounds per square inch or an "A" for atmosphere in the left display segment. Motor speed is identified with a rotating cursor in the left display segment and voltage in the two right segments. [. . . ] Continue dispensing until valve is purged of all air. To determine deposit size, press and hold the program button until the display flashes bright to dim. The valve will begin to dispense while accumulating time on the display. Release the cycle button, then press again; time will be added to the prior sum. Press the program button to save the time. Press the cycle button or optional foot pedal to initiate a complete cycle. Each press on the button or pedal will repeat the same timed deposit. Pressing the button or pedal while the valve is dispensing will stop the cycle. Press up/down buttons to make fine adjustments to the time. Press the buttons momentarily to single step, or press and hold to scroll the time display. Press the toggle button twice to enter the motor speed mode (24 will show on the display). Press the down button to reduce the voltage to 15. Press the cycle button and notice the change in dispensing rate. Press the up button to return to normal operating speed of 24. Turn the key lock to the locked position. Notice that the program, up and down buttons are not operative. The cycle, time override and toggle buttons, however, do function in the locked mode. 9 / Trial Run Operation Review Reservoir Pressure Setting Air pressure is used to maintain a constant flow of fluid from the reservoir to the auger. In general, 8 to 12 psi (0. 5 bar to 0. 8 bar) is enough pressure for solder paste. Some experimentation may be necessary to find the correct pressure for other fluids. Set the pressure so there is enough to keep the auger primed at all times, but not so much pressure that the fluid is forced past the auger when the valve is off. Begin by setting the pressure at 10 psi (0. 68 bar). Operate the valve in time override mode without a dispensing tip installed until material flows from the outlet.
