(Selection of
model "without
unit change
function")
Check for an "M" suffix on the part
number on the name plate
"M" in the part number means
that the unit cannot be
changed.
: The new Measurement Law
prohibits the use of Pressure
switch with the unit conversion
function in Japan.

Product failure
Replace the product.
13
The buttons
cannot be
operated.
Key lock mode
Check if the key lock mode is
selected.

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

Replace the product.
15
Noise.
Air leakage
Check for air leakage from the
mounted part.
(No mounted O-ring)

respectively, and that the output line
has not come off (contact failure).
Correct the wiring.
Opened lead
wire
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.)
Product failure
Replace the product.
