With a remaining quantity of approx. 5-10% grease/oil, the magnetic sensor delivers the empty-signal from the lubricator to the LED signal lamp. When the cartridge is empty, the piston and synchronic the magnet moves with it. Magnet contact the sensor, to the active surface of the sensor. The reed switch is closed by the magnet. Thus, the signal from the supply voltage of 9V block battery supply the red LED on the battery housing. The red warning LED flashes 3 times per second. At the same time, the yellow LED flashes also directly on the sensor.
