– Restore compressed air supply.
– Note maximum length of the sig-
nal lines.
– Run the control and power lines
separately.
– Use screened cables.
– Provide low-impedance paths to
earth.

little.
– Attach reservoir in front of inlet
p1.
– Modify the compressed air sup-
ply, e. g. increase cross-section
of the power supply cable.
