The adjoining figure shows the basic flow
chart for control signal 2 seconds (chapter
8.2.1) which triggers a stroke in impulse

The flow chart shall help you creating a
customized program for your external
control (PLC). This program is essential
to completely control and run LUB-V
properly.
Both PIN 2 and 4 refer to the electrical
interface M12x1 (chapter 8.1)
Proceed the same way when creating
a program to trigger the FIL function
(chapter 8.2.2) but change control signal
