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.
