If the lubricant cartridge is empty, the lubrication system puts out a change signal (rectangular pulse) on PIN 4 between High and Low with a frequency of 0.5Hz. The output signal on PIN 4 is High
(20...30V) during normal operation. During an actual motor run of the lubricating system, the signal switches to Low (+0V). Normally this takes between about 7 and 17 seconds, depending on the
length of the lubrication lines 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 lu-
bricant cartridge.
