Problem Possible cause Investigation method Countermeasure
Improper model
selection
(Selection of
model "without
unit conversion
function")
Check if there is a "-M" at the end of
the part number printed on the
product
"M" in the part number means
that the unit cannot be
changed.
: The unit change function is not
available in Japan due to a new
measurement law.
: It is fixed to the SI unit "kPa",
"MPa".
13
The unit cannot
be changed.
Product failure Replace the product.
Key lock mode
Check if the key lock mode is turned
on.
Turn off the key lock mode.
14
The buttons
cannot be
operated.
Product failure Replace the product.
Air and liquid
leakage
Check if air liquid are leaking from
the piping.
Rework the piping.
If excessive tightening torque
over the specified range is
applied, a mounting screw,
mounting bracket, and product
may be broken.
15 Noisy.
Product failure Replace the product.
Effect of
pressure source
fluctuation due to
small hysteresis
or too early of a
response time
(1)Check the set pressure
(hysteresis)
(2)Check the response time
(1)Check the pressure
setting.
(2)Reset the setting of
function.
Incorrect wiring/
cable breakage
(1)Check the power supply wiring.
(2)Check if bending stress is
applied to a specific part of the
cable.
(bending radius and tensile force
applied to the cable)
(1)Correct the wiring
(2)Correct the wiring
conditions. (Adjust the
tensile force and widen the
bending radius.)
16
The operation is
unstable.
(Chattering)
Product failure Replace the product.
