                CONNECTION DIAGRAM

After supply voltage was applied to terminals A1 and A2, the SAFE Z will be ready for operation. The power LED illuminates. If the button S1 is pressed and within 0,5 sec. the button S2 also pressed, the outputs 13-14,  23-24 are closed and 31-32 will be opened. The machine will be started. The PLC-output (34) is connected with 24 V supply voltage. If one or both buttons are released, the outputs 13-14 and 23-24 open immediately. The output 31-32 closes. Only after releasing of both buttons S1 and S2, a new cycle can be started. If the time for pressing the buttons S1 and S2 will be longer than 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 circuit (repeating contactor control) or a bridge can be connected.
