12
The pressure
display accuracy
does not satisfy
the specifications.
Foreign matter
Check if any foreign matter has
entered the pressure port.
Install a 5 µm filter to prevent
foreign matter from entering
the pressure port. Also, clean
the filter regularly to prevent
drainage deposits.
Air and fluid
leakage
Check if air or fluid are leaking from
the piping.
Rework the piping.
If an excessive tightening
torque is applied, the
mounting bracket, screws or
the product may be damaged.
Insufficient
warm-up time
Check if the product satisfies the
specified accuracy after 10 minutes
warm up time.
After energizing, the display and
output can drift. For detecting
fine pressures, warm up the
product for 10 to 15 minutes.
Product failure
Replace the product.
13
The display units
cannot be
changed.
Improper model
selection (selection
of model "without
units selection
function")
Check if there is an "-M" at the end
of the part number printed on the
product
"M"
in the part number means
that the units cannot be
changed.
(kPa
↔MPa can be selected)
∗: The units selection function is
not available in Japan due to a
new measurement law.
∗: It is fixed to the SI unit "kPa",
"MPa".
Product failure
Replace the product.
14
The buttons cannot
be operated.
Key lock mode Check if the key lock mode is turned on. Turn off the key lock mode.
Product failure
Replace the product.
15
The product is
loose.
Incorrect
installation
Check that the panel mount adapter
and the product are correctly
assembled.
Mount the product on the
panel correctly.
Product failure
Replace the product.
16
The product is
noisy.
Air or fluid leakage
Check if air or fluid are leaking from
the piping.
Rework the piping.
If an excessive tightening
torque is applied, the
mounting bracket, screws or
the product may be damaged.
Product failure
Replace the product.
17
The operation is
unstable.
(chattering)
Pressure source
fluctuation, small
hysteresis or the
response time is
too short.
(1) Check the set pressure
(hysteresis)
(2) Check the response time
(1) Check the pressure
setting.
(2) Reset the function
settings.
Incorrect wiring or
broken lead wire
(1) Check the power supply wiring.
(2) Check if there is bending stress
applied to any parts of the lead
wire.
(1) Correct the wiring
(2) Correct the wiring
conditions (reduce the
tensile force and increase
the bending radius).
Product failure
Replace the product.
