CONNECTION DIAGRAM
If the input circuits S11, S12 and S21, S22 are closed and the start button is
released, the safety circuits 13-14, 23-24 will close. By pressing the stop button,
the safety circuits 13-14 and 23-24 open. After the set time period has elapsed,
the relay K3 and K4 energise. The safety gate switch is released and the safety
gate can be opened. By pressing the start button the relay K3 and K4 are
energised, K1 and K2 energised and close the safety circuits 13-14 and 23-24.
