The lubrication system is switched on as long as PIN 1 has a continuous supply of +24 VDC voltage. Any information saved will not be lost when the lubrication system is switched off. The output sig-
nal at PIN 4 in normal operation is High (20…30 V). The lubrication system has to be controlled by a PLC for it to dispense lubricant on a regular basis. For this purpose, a pulse rhythm for each con-
trol signal must be sent for every lubrication cycle.
