Switching time diagram: Normal case
At the displayed signal on PIN 2, each of the four hydraulic outputs dispense 0.15 cm
3
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 cm
3
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).
