5 Function and application
The control block for two-hand start is a pneumatic AND gate.
If pneumatic signals with a time offset of a maximum of 0.5 s are supplied to the ports (1.1) and (1.2),
an outlet signal is provided at the outlet port (2). Control is implemented using two external, manually
operated pushbutton valves.
– If both pushbutton valves are activated, the outlet port (2) is pressurised.
– If no or only one pushbutton valve is activated, the outlet port (2) is depressurised. The system
exhausts from port (2) to (3).
To trigger an additional outlet signal:
1. Release both pushbuttons.
2. Actuate the pushbutton again.
