Lubrication

    The following signal to PIN 2 results of 0.15 cm3 of lubricant being dispensed to each of the four hydraulic outputs:

    HINT

    Accuracy of the impulses (High) on PIN 2: +/- 0.2s or +/- 10%!

    Switching time diagram: Normal case

    At the displayed signal on PIN 2, each of the four hydraulic outputs dispense 0.15 cm3 of lubricant. Start of the dispensing = output 1.1 or 1.2, then output 2.1 or 2.2. Each hydraulic output is filled with lubricant by its respective piston. Each piston carries out a lubrication stroke. Per lubrication stroke, 0.15 cm3 of lubricant is pumped into the respective hydraulic output. The output signal at PIN 4 is High (+20...30V) during normal operation. During an actual motor run of the FlexxPump, the signal switches to Low (+0V). Normally this takes between approx. 9 and 18 seconds, depending on the length of the hydraulic hoses and the viscosity of the lubricant. The signal then switches back to High (+24V).
