For general errors, the lubrication system issues a Low (+0 V) signal on PIN 4 lasting more than 3 seconds. The output signal on PIN 4 is High (20...30V) during normal operation. During an actual mo-
tor 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 lubri-
cant. Afterwards, the signal switches back to High.
