DNCM−...−POT
Pneumatic components
When using the DNCM−...−POT with electronic closed−loop control:
Please note
Special fitting conditions apply to the electronically closed−loop control of the
DNCM−...−POT:
S Observe the instructions in the manuals for positioning controller type SPC−...
(Soft Stop).
Remove the adhesive labels on the com
S
pressed air ports aG.
When using the DNCM−...−POT as a measuring
cylinder:
Use a one−way flow control valve type
S
GRLZ−..., type GRLA−... directly in the
relevant compressed air port.
If there is a drop in pressure on a system
where the cylinder is mounted in a vertical
position, non−return valves ensure that
the mass remains in the position reached
and doess not slide down.
Using the DNCM−...−POT with electronic
closed−loop control:
Use proportional directional control valve
S
type MPYE−5−... .
Only in this way will the piston remain in
the held position clamped between the
end positions.
In conjunction with such a circuit, the
control electronics compensate for the
difference in pressure due to the different
piston surfaces automatically.
Connect the DNCM−...−POT to the com
S
pressed air ports 1.
