Fig. 5-8 Switching time diagram: Lubrication (normal case)
At the displayed signal on PIN 2, all four hydraulic outputs dispense 0.16 cm
3
lubricant. Start of the discharge = 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, 0.16 cm
3
lubricant is discharged in the respective hydraulic output. The output signal on PIN 4 is High (20...30
V) during normal operation. During an actual motor run of the lubricating system, the signal switches to Low (+0 V). Usually this takes between about 7 and 17 seconds, depending on the length of the
lubrication lines and the viscosity of the lubricant. The signal then switches back to High (+24 V).
