1. Confirm that the mounting adapter
for the regulator is installed

2. Confirm that the Pressure switch is
installed to the mounting adapter
properly.
Correct the mounting
conditions.
Check for air leakage from the
mounted part.
(No mounted O-ring)
Rework the assembly of the
regulator.
If the regulator is tightened at a

Confirm that the brown and blue wires
are connected to DC(+) and DC(-)
respectively, and that the output line
has not come off (contact failure).
Check if there is bending stress
applied to a certain part of the lead
wire.
(Bending radius and tensile force
applied to the lead wire.)
Modify the wiring conditions.
(Adjust the tensile force and
widen the bending radius.)
