Switching time diagram: Filling hydraulic lines / venting the FlexxPump
The filling process starts with the displayed signal on PIN 2. The filling process takes a maximum of 1600 seconds. The filling process is continued after the FlexxPump is switched on if it was inter-
rupted by switching off the FlexxPump. 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). Nor-
mally 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).
