Key features
Function
This pneumatic control block for twohand
start ZSB is used where a manually
started operation, such as the
triggering of compressed air cylinders,
would otherwise involve danger for
a machine operator, or with other
devices where machine operators
have to have both hands clear of a
danger zone when starting a machine.
The ZSB will only switch if pressure is
applied simultaneously via 3/2-way
pushbutton valves to the two inlet
ports 11 and 12 of the ZSB, i.e. within
max. 0.5 seconds, and if there is an
output signal at port 2. If both pushbutton
valves are activated, outlet
port 2 is pressurised.
Releasing one or both pushbutton
valves interrupts the flow immediately
and the outlet port 2 becomes unpressurised.
The system vents from 2 to 3.
