Double-channel
Always check that each channel
in multi-channel solutions fulfils
the safety function.
Diagnostics
Diagnostics for both channels
must be carried out via software.
Special features
The non-return valves also need
a differential pressure in order to
exhaust. In the event of a fault,
a residual pressure of approx.
0.5 bar cannot exhaust.
Safety function
With this set-up, both cylinder
chambers are exhausted via
2 channels.
Exhausting via non-return valves
