When the oil bellow is empty, the lubricating system will send a signal (square pulse) at PIN4 alternating between High and Low with a frequency of 0.5Hz. The output signal at PIN4 in normal oper-
ation is High (+20…30V). The signal will switch to Low (+0V) while the lubrication system's motor is actually running. This usually takes between approx. 7 and 17seconds, depending on the length
of the lubrication lines and the viscosity of the lubricant. Then the signal will switch back to High. You can use the change in signal while the motor is running to calculate the draining time of the oil
bellow.
