CONNECTION DIAGRAM
Af
ter 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.
