Function
The control block for two-hand start is a pneumatic AND gate. If pneumatic signals are sent to the
inputs (1
1
) and (1
2
) with a maximum time delay of 0.5 seconds, an output signal is sent at the outlet
(2).
The control block for two-hand start is controlled via 2 external, manually operated pushbutton valves.
–
The outlet port (2) is pressurised while both pushbutton valves are actuated.
–
If one or both external pushbutton valves are released, the outlet (2) is depressurised. The system
is exhausted from outlet (2) to exhaust (3).
To trigger another output signal, release both pushbutton valves and press them again.
