FESTO费斯托双手启动控制器
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, out
When installing the two pushbutton

easily be bypassed, for example by
pressing the pushbutton valves with
the hand and elbow of the same
arm. If necessary, the pushbuttons
valves should be fitted with an
