3.3 Additional pneumatic circuits
You may require additional pneumatic circuits in order to
attain a particular status for the system in certain applicaĆ
tions.
Please note
If the operating voltage supply for the SPC200 is switched
off, the proportional directional control valve type MPYE
will move to the mid−position. Due to the asymmetrical
voltage−pressure curve of the proportional directional conĆ
trol valve when the supply pressure is switched on, the
slide can move slowly into one of the end positions.
