With the sizes PNG.138 and PNG.V.138 it is possible to monitor
the dynamic pressure of the clamping slide position. Pressure
build-up in "OPENED" status. Control of the clamping slide monitor
requires a reduced pressure supply limited to 2 bar (see chapter
"Pneumatic circuit diagram"
(

4.7, Page 33) ).
The measurable differential pressure must reach a minimum of
0.5 bar in order for a reliable evaluation to be done via the air
gap sensor. The maximum pressure is 2 bar. Monitoring requires
a pressure gauge, an adjustable throttle and an air gap sensor.
For monitoring of the clamping slide, the predefined connection
must be accessed via a base side bore hole.
Request our installation drawings if doing the installation yourself.
