Error message: Empty

    The FlexxPump issues the following signal on PIN 4 if the lubricant cartridge is empty:

    Switching time diagram: Error message: Empty

    If the cartridge is empty, the FlexxPump issues a change signal (rectangular pulse) on PIN 4 between High and Low with a frequency of 0.5 Hz. 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. Afterwards, the signal switches back to High. You can use the signal change during motor run to calculate the emptying time of the cartridge.
