                CONNECTION DIAGRAM

After supply voltage was applied to terminals A1 and A2, the SAFE Z.2 will be ready for operation. The power LED illuminates. If the button S1 is pressed and within 0,5 sec. the button S2 is also pressed, the outputs 13-14,  23-24 are closed and 31-32 will be opened. The machine will be started. If one or both buttons are released, the outputs 13-14 and 23-24 open immediately.The output 31-32 closes.  Only after releasing the both buttons S1 and S2, a new cycle can be started. If the time for pressing the buttons S1 and S2 will be longer as 0,5 sec., the outputs were not released. The outputs 13-14 and 23-24 keep open. The machine cannot be started. On the terminals Y1 and Y2 machine release circuits (repeating contactor control) can be connected.
