The filling process starts with the displayed signal on PIN2. The filling process takes at least 1533seconds. The filling process has to be restarted after the lubrication system is switched on if it was in-
terrupted by the switching off of the lubrication system. The output signal on PIN4 is High (20...30 V) during normal operation. During an actual motor run of the lubricating system, the signal
switches to Low (+0V). Usually this takes between about 7 and 17 seconds, depending on the length of the lubrication lines and the viscosity of the lubricant. The signal then switches back to High
(+24 V).
