Fluid Plates
Problem Cause Solution
No outlet pressure Air pressure low Verify air pressure is above 60 psi
(410 kPa, 4.1 bar)
No “Valve On” signal from automa-
tion unit
Check output and wiring from
automation unit
No air signal to air diaphragm Check for loose/disconnected
connector to Voltage to Pressure
(V/P) Transducer; tighten
False signal being sent to control Check outlet pressure sensor output;
verify that it corresponds to zero
pressure; replace sensor and/or
amplifier
High outlet pressure Fluid regulator needle/seat is worn Rebuild fluid regulator; replace
needle/ seat
Air leaks from fluid plate Loose air connections Check air connections; tighten if
necessary
Worn gaskets Check/replace gaskets on Voltage to
Pressure (V/P) Transducer and
solenoid valve
