A.3 Additional pneumatic circuits
You may require additional pneumatic circuits in order to
attain a particular status for the system in certain applica
tions.
Note
If the operating voltage for the CMAX is switched off, the
VPWP proportional directional control valve will move to
the mid−position. Due to the asymmetrical voltage−pres
sure curve of the proportional directional control valve
when the supply pressure is switched on, the slide can
move slowly into one of the end positions.
