Possible cause
Operating pressure is too
low.
The maximum achievable
force on the DMSP/MAS is
less than the required force.
Supply pressure is too high.
Load is too high.
Diaphragm is worn out.
Air volume is lacking.
Valve is too small.
Remedy
Increase operating pressure (observe
maximum permitted value
è 13 Technical data).
Select a larger DMSP/MAS.
Reduce operating pressure.
Reduce load.
Replace DMSP/MAS.
Increase connection cross-section.
Place volume upstream.
Use short tubing lines.
Use a larger valve.
