8.1.3 Control
Leantechnik recommends the following pneumatic controls. The
piston chamber is filled with compressed air, thus eliminating
the spring force. In the event of a power failure, the compressed
air in the piston chamber is discharged. The spring force acts
on the clamping element. The profile rail is clamped/braked.
Switching time-related applications
• Select the shortest possible cable paths. Cross sections
and the lengths of the cables influence
the response times considerably.
• For faster brake application we recommend a
quick exhaust valve (6) (selected according to the
compressed air connection thread).
• The size and speed of the 3/2-way valve (5) influences
the switching time.
Safety-related applications
• Use of a proximity switch for
switch condition monitoring (see Section 9.1)
• In addition, use a pressure monitor (pressure switch 6)
between the brake and the quick exhaust valve.

Recommendation!
For applications to optimise the
switching time (reduction of braking path)
Note!
The flowing away of compressed air must not
be compromised by any other
components.
Recommendation!
For applications to optimise
safety (in case of danger to persons)
